Title: Laverda Jota Ownership, second time around. (ramblings)
Post by: cbertozz on December 04, 2016, 22:28
As I am just getting up to speed with owning my 180 Jota the second time around (the first being 25 years ago) I thought I'd create a thread to contain my ramblings as well as the usual posts elsewhere on topic, as in the past I've found this a great way to keep track of everything that I've experienced with the bike, and it means you can easily ignore. Apologies for the repetition here but wanted to make the thread complete. There seem to be few new owners who have no experience of these bikes coming into ownership but for those that there are might find it useful/interesting.

My love affair with Laverda started as a child in Northamptonshire, a small village called Stoke Bruerne, where a pair of Laverdas, one orange, one green, would park up each year by the bridge. That image was clearly seared on my consciousness and surfaced when I pulled back the dust covers on this bike after finding it in a sorry state in an 'under-the-arches' garage in South London in 1991 after being towed there after my Guzzi Le Mans broke down. I managed to secure a part exchange after much haggling and after confirming it was indeed a 180 Jota engine (had them open the thing up and show me the 4C on the cams - can't believe I did that!). I commuted around the UK for a couple of years, riding London to Brighton and Northants to London in all weathers until the bike expired in late 1993 and I was without the cash to revive it (just married, first house etc), so it went into storage until 2001 when we emigrated to the UK. At that point I took it to Slaters who got it back in working order. I rode it for a while here in Australia before selling it to a member of this forum where it stayed for 15 years, the last 10 off the road (the lucky man had two Jotas) being gradually restored with the engine rebuild done by Redax.

I should note that I have no mechanical experience or skills beyond the basics I have picked up over the last couple of years racing in the Moderns class. I have learnt to do more in the last month or so of Laverda ownership than I have in my previous almost years of riding, and I have been graciously assisted by the members of this forum who are generous with their time and experience obviously gathered over many, many years.

The only picture I have off this bike from the first time around. My son is now almost 21.

So the things I have learnt to date, or have had to grapple with.

Rear Suspension - the bike has Gazi rear suspension which has a lot of damping adjustment but the length of the shock means the centre stand isn't 100% stable. I've got them as short as they can go but will need to shorten slightly again for the stand to be 100%. Other than the fact that I have minimum preload on to keep them as short as possible they work well, and have highlighted the need to get the front sorted.

http://www.gazisuspension.com/sources/images/products/main/HyperX_01.jpg

Front suspension - the bike has Sportsvalve gear fitted which gives rebound and compression damping but there's something not right with the forks. They are way to stiff and don't really move when riding, making the front a little skittish. It is no doubt a function of age so will get them stripped down and looked at, something for someone more skilled than me. I suspect the front needs putting back together carefully, and that even the mudguard is part of the equation as its pretty solid!
Once sorted then the adjustability will be great to fine tune, shame the caps don't fit under the Jota Bars (worth noting as I paid extra for these).
http://sportsvalve.com/sports-valve-fully-adjustable-damping-control/


The clutch has a an EasyClutch mod by Greg Parish at DAM Laverda, and was the first mod I did to the bike. It seemed like a good value and quick mod that would allow me to ride with comfort and I don't mind the look at all. I can't be doing with all the macho shit about the original lever - I did that years ago and it was a PITA then and I'm glad such a low impact, low cost conversion is available. If I feel flush I may get a hydraulic version down the line.
http://www.thedam.com.au/The_DAM/DAM_Laverda_Easy_clutch.html

The Gear selector return spring on the Shift foot broke shortly after taking ownership but I was able to source one from DAM and it was fixed in a few days. The fact I've been able to learn something about the bike in the process is great, never having opened any sort of case on a bike before, albeit this is really just an outside case and no too messy. Learnt that I can lean the bike on its side and work on the selector without having to drain the oil which was a tip I saw somewhere on this forum. The eccentric in the gearbox selector was another interesting voyage of discovery, and setting that has helped improve the gearbox considerably. Have been fine tuning to try and get it perfect but having some issues trying to lean bike and get back wheel off the ground! Managed it once but have struggled since. Anyway hopefully no more needed in that direction. Making sure the mark on the inner gear and the gear selector spindle was another learning. Hoping this is pretty much sorted now.

The Jota bars, I like the look of them but seriously considering clip-ons. I have adjusted them down to how they were originally, much more aggressive stance, but with the stiff front end it didn't feel good so put them back to straight up. Once the suspension is setup properly at the front I will have another look. I put on some new grips but they are too short to cover the throttle tube so back to the drawing board to find a set that work, otherwise will just have to refit the old ones which I believe were Suzuki. Someone I am sure will have a suggestion and I'll post about this later.

Instruments - I have a kit from CB750faces which looks great, just have to find the time to remove the clocks and get all the bits and pieces put back together. Minor annoyance is the bouncing speedo needle but I'll get that looked at when I get the clocks done.

The side panels I could have got from a variety of sources but not having done my homework I ordered from Europe when there were some here in Oz with Redax, and probably others. Anyway... Incidentally I sourced the badges for the side panels and tank from Badge Replicas, and the quality is great http://badgereplicas.com.au/

Some other things I have had to re-discover like adjusting the rear wheel - although I could not for the life of me see how I could loosen the rear caliper properly, I could get at one nut but not the other. I used an old-school method with the string around the back tyre and it worked well, the rear was out of alignment and using this method and a digital measuring caliper I was able to get it straightened out and the bike feels better already.

Anyway that's about it for now.

2 things, Jota Bars are a great idea that has some issues in the real world. The adjustment is pretty course and mine would always be just 1 click out. Do yourself a huge favor and get the Bushman Lawton Kawasaki side stand kit,cheap as chips including the Donation to Charity Joe make. It's so much easier than the centre stand,and more stable. I keep the centre stand on the bike for maintenance but use the sidestand 99% of the time.

Gidday,

Sorry if i missed it but what part of Oz are you from?

Lots of things you can modify and play with but a skittish front end sounds like an accident about to happen!  Get the front suspension sorted asap! 

I spent a lot of time effort and money on the front fork of my 3C, still not as good as the standard marzos on my 120 Jota.  If in doubt return to original and start again.

Cheers

Marty

Post by: cbertozz on December 06, 2016, 15:48
So apparently my stiff fork issues were caused by three issues:

- too much fork oil (100ml too much)
- spacers below the sportsvalve that was preloading an already heavy spring
- Fork legs that were being splayed by the spacers and aftermarket discs that were making contact with forks - not sure what happpned here but we've sorted it now.

So the forks should work beautifully, although I won't find out till Friday.

I've asked the guys to grind off that collar on the throttle tube so we can get the Madura grips to fit.

I'm not brave enough to take the front end apart. It's all good, this is the sort of stuff that you work through when you get a new bike, it's always a work in progress and the bike has actually been nicely put back together for the most part and now its basically finished.

So had the collar on the throttle tube ground off today, and so the Magura grips fit well and look good. Very grippy, not particularly insulated from vibration but hey I'm not even 50 yet!

The heaviest springs Shock Treatment has are 0.95 Eiboks{sp} They are too light for me and needed to much preload to set the sag.One of these days we might start a post on what springs people use and how that works with there weight. The Race Tech auto system isn't that helpful getting a good result re springs,BTW they list Ceriani 38mm forks in their Vintage section in the spring calculator.

Title: Country ride today
Post by: cbertozz on December 11, 2016, 10:06
Just so I don't forget: riding the Dewars Pool road from Toodyay to Bindoon and then down the Chittering road, was great fun. Stayed comfortably on the pace and the bike felt solid and stable. Rode it like a race bike and it responded to Weight over the nose and didnt skip about as more modern bikes often do on their fat rubber. The Long slab of a tank makes a good pivot and although the pegs aren't rearsets they are pretty high so make riding on the balls of your feet easy. Only issue was that by the end of the day the rubber on the right peg popped off down the road, luckily I was able to recover and refit (note to self to check when stopping). Great bike.

So stopping on the side of the road on a red dirt sloping verge in country Western Australia is always a bit tricky at he best of times but with only a centre stand that isn't 100% anyway its a bloody nightmare. (note to self get a kickstand). Was a great ride up to that point.

(http://www.laverdaforum.com/gallery/albums/userpics/13570/normal_Screen_shot_2016-12-11_at_6_02_48_PM.png)

When the bike began to splutter I was fairly sure what it was but buggered if there was anywhere to safely pull over (a fair few people get cleaned up on WA roads each year, plus the fact that the bike nearly ended up in the ditch!). Luckily was able to limp to a local servo.

The culprit was obvious. Reckon these are the 80s vintage leads. Easy fix

Depends.  I dunno if the current ones are modified to Keith Nairn's spec, in which case yes, you can keep the centre stand, but the original ones foul the centre stand tang unless you bend it (looks bad) or remove it (what I did)  Didn't miss it once I had the Bushman/Lawton stand on, and I just bolted on the centre stand if I needed to work on the bike.

You are going to need a relay and a hot wire from the battery to power that horn. It draws more current than the stocker, can melt things.

Post by: Brett on December 11, 2016, 21:14
Its a Bushman bracket with a Kawasaki ZX6 stand I would say..........you will need to mod the foot on the centre stand in some way to make it work if you bolt it straight on.... some clever chappies here have made a modded bracket so you dont need to bugger up the centre stand. Jotajoe on the forum here used to sell them send him a line he might still have some brackets.. then you just got to find a stand and bobs your uncle.
http://www.laverdaforum.com/forum/index.php?topic=91629.0 (http://www.laverdaforum.com/forum/index.php?topic=91629.0)

With the horn/horns yep wire in a relay definate good plan... two fold the horns will work better as now all the current for them aint going through the button and if one for some reason parts company with the bracket the wire wont then short on the exhaust and cause the bike to die.... good ole Laverda and minimum fuses... :o
Use the search function and you will a wiring diagram for this.

Plug leads I use dynatek silicon with copper core  wire cut them to length, fit termnals and boots to coil end and screw on the caps to tother
... though if you go to one of the local motor factor stores who specialise more in performance vehicles you should be able to pick up some 7mm copper core plug wires with right angle coil ends, cut them suckers to length  ... a set of new NGK caps XB05 caps and bob;s your uncle..

New Ikon springs fitted.  New HT leads on.

Quick test ride up the coast. Springs working fine but nay still need some adjustment, haven't put any spacers in yet, will give them a few days to get used to it, then will give the spacers a go. I seem to remember that a spring with very little preload can feel firm because the spring is at the wrong part of the springs compression.

Old springs on the left, new Ikon spring on the right.

Post by: Dellortoman on December 16, 2016, 23:00
You will need preload spacers Carlo. Front end must be a bit saggy without them, especially since the new spring looks a bit shorter than the original one.

Measure how much the suspension sags with both wheels on the ground and you sitting on the bike with your feet on the pegs (may need a second person to help hold the bike vertical take the measurement). I usually measure between the bottom of the lower triple clamp and the top of the fork slider.

Sag is the difference between full fork extension and where the suspension sits with bike and rider weight on the wheels.  Around 35mm is optimal.

The proper way to measure sag is to compress the suspension, let it rise slowly to its rest position and measure. Then pull the handlebars up to extend the suspension and let it settle slowly to its rest position and measure again. Take the average of the two measurements, subtract it from the full extension measurement and that's your sag.

Incidentally, the difference between the two measurements is an indication of the amount of stiction in your forks. Less than 10mm is good.

I suspect that you'd be somewhere around 70 mm sag without any spacers. Once you've measured it, subtract 35mm from that measurement and that's the required spacer length.

I use orange electrical conduit to make my spacers. I trim them to length in the lathe to make sure the ends are square. Well, OK, they're still round, but you know what I mean  ::)

Happy to make up a pair of spacers for you once you have figured out the length required.

Cheers,
Cam

Greg sent them with the springs. About 1" in length.

However, I just measured the front sag and its at 38mm, call is 40mm with gear, which is about right for a road bike. I put a small washer inside when I installed them which would have given me an extra 3mm or so but no more. So I got lucky.

To be fair when I took it for a ride today it felt good, not wallowy at all. Good under brakes and in the tight and more sweeping turns.

You will need preload spacers Carlo. Front end must be a bit saggy without them, especially since the new spring looks a bit shorter than the original one.

Cheers,
Cam

Gotta remember it has emulators fitted so probably had too much preload with the original springs.

Post by: Vince on December 17, 2016, 05:31
You do need at something solid between the springs and the preload tube so either bear nicely,don't dig into or eat each other up if you get my drift. A nice thick washer with a small hole is fine.

Post by: cbertozz on December 17, 2016, 13:34
Need to cut the spacers into shorter lengths. Typically on a modern sportsbike one full turn of preload is equivalent to 1mm but that's with upside down forks. Are the normal telescopic forks less sensitive? Otherwise it seems like I'd be better adding a 5mm spacer first.

Need to invest in a proper work bench and a bike lift to secure and work on the bike.

Considering the flux of his post in this forum, it's highly unlikely he's real.

I've tried to help him out over his various issues but it's as if our input falls on deaf ears as he always changes the topic. Perhaps he is a Motorcycle Moron and should pay a Motorcycle Mechanic.

Something is not adding up for me.

You know damn well our Breganzies are not perfect and demand attention and usually found in the hands of seasoned Motorcyclists.

What's more, to days Mechanics know absolutely nothing about maintaining, rebuilding and tuning carburetors. It's all about reading codes, resetting the ECM in EFI Fuel Systems and I doubt one could even clean a TBI unit without bolting a new on.

To be honest early on I was suspecting some trolling but now I don't. I like the fact he asked some basic,to long term owners,questions. It's good to go back to basics and generate some activity here,at least it's better than see this bike for sale posts,that seems to be all that's happening lately. If that's all that happens people get bored and piss off. If you don't like it don't read it or get involved,easy fix. It's good to see someone invest in and RIDE a Laverda and look at fixing shit.

Had a great ride today, found a rollercoaster of a road that I never knew existed. Really quite unnerving to be heading downhill fast on a steep hill and not be able to see the bottom of the hill.

Have a number of new jobs to get my head around. This is as much a list for myself as anything else

- change to 5w fork oil, as suspension still a bit harsh and the Sportsvalve people recommend 5w with their gear. (has 10w at the moment), If its still bad I'll make up some spacers.

- Have to sort battery - still not 100% sure but it's not charging properly when running. It was 13.1 when I headed out and came back it was 12.35v even though I'd only used indicators/brake lights. Most likely it's the battery so going to make sure its properly charged and then see.

- have to install a different grease nipple on the swingarm, the one thats on currently points backwards at 90degrees and is obstructed for even a flexible hose.

- Need to order a workbench so I can work on the bike properly. Hopefully something where hold the bike and i can drop the rear of the bench so I can spin the rear.

- Going to take the recommendation of an LED running light.

Your ignition is also an electrical load.  Since we now know you have one of Red's excellent ignition & alternator upgrades, your battery should remain fully charged after a run.  This is pointing more at no charging (broken wire/duff connection) or blown reg/rect than the battery itself.

Yep off to buy a voltmeter.

Have fully charged the Shorai battery. It seems to lose charge overnight even with the battery tender attached it didn't fully charge, was 13.3 which according to Shorai is 90% so I'm.not entirely convinced I don't also have a slightly knackered battery.

There should no issues with the extra charging of Reds kit AND a trickle charger. Either as Rob said the juice isn't getting through or the battery is knackered. You can get the battery loaded tested at most bike shops but I have had issues with that, battery supposedly good at 80% but not starting the bike. It also could a MASSIVE parasitic leak,power draining while the bike sits turned off but with a trickle charger on it would be an amazingly big drain. Pull the battery out and do the load test thing.

See you are using a Shorai charger.  Assume you are pressing the Charge button? Did the Charge LED light up to show full charge achieved? Your SOC (state of charge) table shows that 13.1v you measured could mean SOC as low as 40% capacity  :(

The LEDs also provide some diagnostics - see user instructions

My recommendation, if you don't already have the Shorai charger, get one and balance the pack and then do it periodically after that. If not, these are two to three year batteries...period...forget all the hype about long life.

Ye I'm using a Shorai charger and when I plug it in both store and charge lights start flashing, indicating less than 50% charge, then eventually I can push Charge and the green light flashes and eventually both are solid. Then I press Store and it flashes orange.

Yesterday I charged overnight and it was at 13.3v. Today I ride 20km to work, did a couple of short trips and then 20km back with headlight on just for tgatast leg home on freeway.

When I checked the voltmeter showed  12.9v which the manual says is 30% charge, so something is definitely wrong.

I need to buy a proper gadget to measure all the things and check out Red's instructions for troubleshooting because he knows the system inside out, and I need time!

The thread continues despite the interruptions.

The bike is in the shop for some diagnostics around that charging issue, should.find out later today what the situation is.

Spent yesterday talking to the historic racing community here in WA, and some helpful souls on this forum, to establish requirements for putting the Jota on the track.

Good news is it's relatively easy once you have engine protection sorted, then it's just the lock wiring etc. The log book application is the only thing that needs urgent attention to make sure I have it in time for the season.

Also popped in to see Paul at RetroMoto On the way past and discussed the front suspension - the forks aren't quite right. We agreed that we'll strip them down after Christmas to what's causing the harshness. In the meantime I'm going to make sure the damping is set to its absolute least on the Sportsvalve.

Haha ye Rob does a good job. Will get him to do the Jota for the new season. Gold doesn't seem right for racing.

Anyway back on charging, turns out to be a bad earth that was affecting the charging and would have been affecting everything else as the same point t was used for everything - the frame wasn't rubbed back enough after powder coating.

Happy days  ;) ;)

When I did the wiring during the rebuild I ran earth wires everywhere including a heavy earth wire to the starter motor. All run to a single point on the frame which is also the place the earth wire from the battery is connected. Absolutely no problems with earths anywhere despite powdercoat and paint.

Well couldn't face any major mucking around as it's getting late so opted to try re-route clutch cable and grease the pivot point.

Should know never to start jobs when I'm tired. Have now stripped/split the cover on large sections of clutch cable Turing to remove. Now.i need a new cable FARK.

Going to use remaining time wisely this evening and work out the best way to route it. There only seems to be one viable way but maybe not.

So got around to replacing the knackered (by me) clutch cable this evening.

Some other adventures along the way...actually first time I've taken the tank off (too easy, now worried by how few things hold the tank on the bike - couple of rubber bungs, fuel pipes ( :o) and a large rubber band!  :o

Then realised I'd lost the slotted screw which attaches to the adjuster wheel on the handlebar. After much swearing and searching through my less than tidy garage with a torch I found it lurking in the wiring around the neck of the bike!

Then couldn't work out how to get the two ends connected, they seemed a bit to short, but then eventually realised I just hadn't adjusted properly, which took me a little while. I posted and then figured it out before someone shamed me with an obvious answer.

There's no more 'clicking' from the lever, adjusted both clutch and brake to make sure they move only in the desired plane, and greased pivits to help them on their way.

Took the opoortunty to make sure everything else under there was firmly in place and tied up a couple of leads. Thanks to Dellortoman and Dave48 for their thread contributions earlier this year which guided me in terms of the routing. It much better than previously, helped by a slightly narrower cable as well.

Post by: Vince on December 22, 2016, 16:09
Hope you haven't snugged down the clutch cable under the tank with cable ties,it needs to be nice and loose with as bigger loops as you can get. Where I alway have trouble is where it goes along the handlebars and down into the tank. I find it hard to work out above the tank rubber or below? Still haven't got a good answer on that in close to 30 years.

Everything as loose as I can make it, no cable ties. The place I'm trying to avoid issues is where the cable is under the tank.

Nope, the EasyClutch works just fine. The cable was the issue, I'm now able to change into neutral when stopped, gear change is smooth.  The old cable.could.have been routed better and was so thick it was less free. Everything felt way better now, easier to feed in clutch and smoother action.

Fitted my trusty laser jammer. Fitted rear sensors while I work out the best was to do the front. Before anyone gives me a "they don't work" speech I've had this unit on. 1199 Psnigale and a BMW HP4 and not one ticket (so far).

Also changed gear selector gasket so hopefully that's that weeping oil leak fixed.

Speed camera detectors are allowed in the UK as they are deemed 'safety' cameras, but jammers are a big no no.
Pretty sure if a cop couldn't lock on to you he would stop you PDQ and put you in a world of hurt.

It's on when you're riding. I don't have the front jammer installed at the moment so I'm fair game but those pesky multinova cameras that are rear facing are a bitch so it covers my arse.

The system shuts down 5 secs after jamming so that the policeman can get a read by which time you're on the brakes. It resets 30s - 60s later depending on how its set.

Seems the Queensland's have a new threat, small Orange Speed Cameras mounted to trailers left on the median strip of expressways. Don't know how long they will last sitting alone by themselves, we in NSW get manned speed camera vehicles. But if you don't have to pay an Operator a wage to sit on them that's more profit to them.Gives me a nice warm feeling in the arse to see they are looking out for us. BTW Radar detectors are strictly forbodden and they seem to have Detector Detectors, no idea about jammers. First I have heard of them.

In Spain I routinely saw pigs in a plain car with laser speed detector hidden in the vegetation in the central reservation about a few hundred metres beyond fixed grey painted speed cameras.
I also saw a tiny camera on a tripod hidden by a brick farm building on a rural road, absolutely no chance to see it as you whizzed past.
And at the Pinkstertreffen in Balkbrug the pigs set up a speed camera in a wheelie bin by the side of the road.

Well not sure what I did there, locked the topic somehow!

Anyway, changed fork oil tonight and tried to adjust the Sportsvalve valves - pretty sure they are knackered. They are not adjusting properly, cant feel any clicks on rebound. They were working before but after they were taken apart recently I'm guessing they put them back together wrong, which is bloody annoying. Will see how they feel with the 5w back in but almost certain they will be harsh, something is jammed. Waste of bloody money and I don't think I would go for Sportsvalves again on a Jota.

Bike ready for a country run tomorrow. Given the suspension is still suspect I'll be taking it easy on the bumpier sections.

I've found the handling at the front is much more to my liking at 42psi. Haven't settled on an ideal pressure for the rear.

New clutch cable has been the icing on the cake, bike runs well. The bike rewards being ridden hard so looking forward to fork strip down. If Sportsvalve is buggered I won't be replacing them.

My one partially refurbished tacho looks good so looking forward to the completed refurbishment.

You may have to if the damper rods have been drilled. Either that or swap to Racetech emulators. Either that or chase down some damper rods from folk who have had a cartridge conversion. I did ask at Maxtons but they said they sent all old parts back to the owners with the converted forks.

Somedays you are one with the motorcycle. The throttle is just an extension of your consciousness, the gears are seamlessly in tune with the movement of your right ankle; you pivot effortlessly off the foootpegs, your inner thigh pressed flat against the side of the tank as you hang over the bars, rolling on the growling, smooth power while the sonorous sound of the triple resonates off the scenery around you.

Today was not one of those days. Shifting gear was a clunky, crunchy nightmare and I was about as far from being in tune with bikes as if it had.....Well you get the idea.

Perhaps tomorrow...

We saw quite a few cops on the expressway between Sydney and Newcastle but zero on all the great bike roads we did in the last 2 days. They have plenty to do on the major expressways where all the once a year carnage happens.

So after a bit more riding with 5w oil and no spacers I was finding the new springs too soft.

 I checked the sag and it was way off as expected, with 55mm. So I chucked in the spacers that I had to hand and now I'm running around 25-30mm.

Put new nylon nuts on the handlebar clamp bolts as I've stripped one before.

The new handlebar position is much easier but needs to adjust down just a tad, will try the lead washer trick mentioned elsewhere on the forum.

The spacers make a big difference. Bike feels more supple. Have added some more proad to the rear to try and maintain/improve the geometry, with the slightly annoying side effect of the centrestand now being less stable.

Well today didn't quite go as planned. Bike conked out and had to get a tow truck.

I did my best to be the bush mechanic but couldn't find anything obvious wrong (I.e no loose, broken or disconnected wires.

Bike appears to have no spark. Anyway these things happen and once diagnosed I'll know what I'm looking for next time.

So managed to get to the bottom of the no spark issue eventually.

It seems that there were multiple issues:

- A lose earth causing intermittent cutouts and which like scrambled the ignition programming.

- The ignition box which understandably needed to be reflash with correct map.

- The relay which when bypassed  allowed the who lot to work as it should.

Anyway learnt a lot about how the bike is wired and how it works, learnt how to use a multimeter (don't laugh, never touched one before) and now have the diagnostics platform sorted in case I ever need it again (did you ever fit that TPS Paul LeClair?)

Vince: Interesting but can't see the point of it where Venture Atomization could be sync'd to an ECM where a simple set of points "TUNED" would be much more simpler and easier to maintain.

Anyone owning a Breganzie are not dummies.

So Cybertoss has some sort of antiquated aftermarket ECM ignition system linked to the throttle of his carbs?

I might go with a Mag Trigger, Halls or Photo-Electric Trigger with a CDI Box with  Carbs - What in hell does he have that uses a TBI system on a Carb Throttle?

Maybe I'm clueless. Perhaps a Laverda DMC Ignition Module but never heard of one with a TBS for Carbs but may require a MAS (Mas Air Flow Sensor or Vacuum Sensor) for it to work. I never knew these systems existed. Enlighten me more.

I'm really curious - Seriously, because I've always thought of that system ;o)

Hey Ron,

The Ignitech ignition that Cbertozz has on his bike is quite sophisticated. It has an input for that can be used for TPS or MAP (manifold absolute pressure) which can be used to map the advance curve against.

What you end up with is two inputs to for the ignition, RPM and throttle setting by either TPS or MAP. So its a 3-dimensional ignition timing curve.

There's nothing new about a 3-dimernsional advance map. Cars have been doing it for donkeys years. The old mechanical advance system in car distributors used centrifugal bob-weights to advance the ignition as revs increase, as well as a vacuum advance.

Cape (forum member in Finland) has found much improved fuel consumption on his Laverda by using the TPS input on his Ignitech.

Just as an aside, the Ignitech also has an analogue servo output that could in theory be connected to a throttle actuator. Taking an input signal from a handlebar mounted TPS and using it to drive a throttle actuator motor on the carbs will give you fly-by-wire throttle. That's something I'd be interested in having a go at. No more straining against heavy throttle springs.

After they fitted the Miks at Reds shed I did a 50k test ride with Mark, had a problem that got sorted but one thing along the way I found was the VERY strong return spring. It was that strong I found it hard to blip the throttle on gear changes and yes I very bravely complained and got what I expected from the boys, after the usual 20 minutes of girly man comments Mark did an adjustment that backed this return spring off a lot. That made a hell of a lot of differance, Cam have you tried this adjustment. Mine is much easyer now.
It involved pulling a grub screw out and allowing the shaft to release tension, or that's what I remember

Found them to be much lighter than holding the throttle on against the spring in damn Dels. Still trying to figure out a sensible solution for the Goose.

You think yours are bad, try an early 3C: the springs on *1173* are killers :o :o. On my T3 Cal there is a 'cruise' screw to hold the throttle. works ok but can't be adjusted in a hurry so probably not the safest invention (like a hand throttle in a 73 series LandCruiser) :o ::) ::)

I have Mikunis on both my Laverda triples. Lighter throttle pull than the old Dells and quite OK.

My throttle issue is the same as Davo's. My Guzzi LeMans has a rather heavy throttle. I've made it a wee bit easier by optimal cable routing and greasing the ramps on the slides that operate the accelerator pumps, but it's still a bugger of a thing. Next thing to try is some lighter throttle springs, and maybe a single cable from the twistgrip going to a splitter somewhere under the tank.

As for the girly-man comments, It's OK for you young whipper-snappers (under 60). Heavy throttles didn't bother me up until a few years ago. In my old age I think I must have some deterioration in either the nerves or circulation to my hands (carpal tunnel syndrome?). Having to use a strong grip on the throttle eventually causes a pins and needles sensation in my hands. On long rides it can get quite painful.

You should try the death grip I used  on The Snowy Run and the recent 2 day Oxley Run when the grip glue let go. Well it was ok with the cable ties except the Sikaflex silicon I tried as a grip glue that failed reduced the friction as well. Every 5 minutes I had to twist the grip back to clear the heated grip wiring from the brake lever. What I really missed with the cable tie fix was the Cramp buster throttle rocker gadget that I always use.
Holds the throttle open just with the weight of your hand. Had to take it off with the cable ties not allowing it to work. Love that gadget on a long day. Now that the Araldite is working its going back on. I also added one of those thumb actuated cruise control locks, had it on years ago but removed it after I had the plastic slides melt on a set of CV carbs and that got the blame. It took years to find it was CAM TIMING OUT ONE TOOTH, Bloody Obvious but smarter people than me blamed this Cruise Control.

Just reduce the throttle spring pre-load a bit, Cam.  Works wonders.

I've always been bothered by heavy controls.  Throttle, clutch, really no need for them to be so stubborn.  Lighter controls are loads easier to use consistantly, a light throttle results in cleaner engine response because the carbs can be controlled far more precisely.  A lighter clutch action allows finer dosing of the clutch if the need should arise.  Much the same for the brakes, a "softer" action makes braking far more predictable. 

Making long trips easier on the limbs is a nice by-product. ;D

Just about every car with a carburettor engine has vacuum advance. The vacuum diaphragm on the dizzy performs pretty much the same function as TPS.

Bikes don't usually have a vacuum advance system, so a TPS is one way of doing the same thing electronically.

Only way to do that is cut a bit off the springs, which isn't a reversible modification. The carbs won't close fully if I take too much off, so I haven't gone down that route yet. Might be better to buy some lighter springs. Stein Dinse lists several different spring rates for these carbs. I'll measure the springs and work out what spring rate I have now.

The triple Mikuni setup on my Laverdas can get away with a lighter spring because they have positive closing via a second cable. Some call it a push-pull system, but that's a misleading name.

I changed the tops on the dels so that the cables ran a better line and angle of action was improved and put in lighter springs. Still bloody heavy compared to the Miks on the Laverda with the pull-pull cables.

Have to go get a replacement fuel line today, has to shorten one of them after it split at the end. Hoping I can get a slightly easier to work with, these seem quite brittle.

Also trying to work up the enthusiasm to shorten the rear shocks with the new eyelets from Gazi but maybe I'll save that for another day.

Those original Cavis-Benz fuel lines aren't much good. I think it's probably PVC which goes hard and brittle when exposed to fuel. They need to be replaced quite often if you want them to be supple. So often that you may as well consider them a consumable item.

A better long-term solution is a black rubber fuel hose, or if you prefer the transparent look, go for polyurethane fuel line.

Well I did replace fuel lines and frankly they are a disposable item, I bought a few metres of hose from local dealer.

Did a quick test ride up the coast after shortening the rear shocks (though then wound on the desired amount of rear preload so fairly balanced it out.

I've replaced coils, plugs, new caps all round and checked all the wiring but coughs and splutters at 4500-5000 and later at 6-7 etc.

I've got this relatively low powered battery in there but surely once it's running that should be fine.Anyway will have another look tomorrow.

I love this bike.

It's the perfect combination of performance, comfort and style, but I particularly love how it sounds on full song!

It's also designed to be ridden well. I've been really surprised this time around having had a couple of years racing that you can really ride it  like a race bike up on the pegs, pivoting off the tank weight over the front. If you ride like that you can get the best out of it but you can potter along the coast quite happily.

IF the wiring is OK and there are no intermittant connections, sounds a lot like insufficient fuel supply.  Float heights, clogged filters, and/or petcocks are possible issues.

Have you thoroughly checked the carbs and petcocks?  I read one tap is difficult to turn.

As has been said before, electrical issues often turn out to be carbs, and vice versa.

IF the electrics have been properly sorted(what I'd expect after all you have reported), there is no real reason for the engine to cut out because of them.  The rev ranges you describe are where the engine is producing max torque and power, ie, requires the most fuel.

I would attend all possibilities before limiting myself to just one... and end up running around in circles!

The fuel taps can easily be re-built(just did a set for my racer), sealing rubbers available from OCT if you can't source them locally.  Original taps are no longer available, repros are close, but not identical.  The repros also have a much shorter reserve range.  Unfortunately, the Original Orlandi/Paoli parts will not all interchange without a bit of modification.

And for fucks sake, get some proper fuel line clips!! ;D

I just happen to have the tank off my brother's 3C as I type this so I took a couple of photos.

Rear tank rubbers are domed plugs that fit in the top of the vertical frame tubes behind the engine. They seem to last forever. I've never heard of them wearing out but I suppose it's possible. They should stand about 23mm above the top of the frame tube and have round domed top on them. If they've worn down or flat on top then they're past their prime.

Front rubbers are 30mm diameter cylindrical knobs that fit snugly over the lugs on the frame.

Rears don't wear, front ones do!  They get rather soggy after a few years, surprising how much they allow the tank to move around.

Went for a spin down the coast just to get some air and while riding I noticed that there was no fuel coming from the left hand tap so perhaps that's the issue. That said I did drain the tank last night so perhaps I've dislodged some crap that has clogged the tap. Who knows! Will have to wait until the taps arrive as I can't imagine there's much I can do without removing the tap fitting.

You could try removing the tube from the carby and blowing back through the tap into the tank and see if the dislodges any crap. If you don't hear a bubbling sound from the tank and your cheeks stay distended you'll know you have a blockage. ;)

I reckon the reason your tap handle is hitting the cam cover is that the tap needs to rotate a bit on its thread. Just back the nut off, turn the tap and re-tighten. It can be tightened with the tap in any position.

PS: posted a photo to show what I mean. The tap handle overlaps with the cam cover, but needn't touch it.

Now I'm wondering how old those spark plug caps are on Tim's bike. They appear to be unsuppressed. They don't have resistors in them and he isn't running resistor plugs either. Doesn't seem to bother the Ignitech program though.

Fuelling was good although I didn't open her up at all.

They're fuckin' ugly!  :o

And the ones that are usually used are far too big and will not seal properly and often chew up the hose.  The factory installed tiny jubilee clips early on (band about 3mm wide), later they switched to foolproof, simple-to-use wire clamps.

People lavish 1000s of bucks on engine re-builds, paint and snazzy shocks, and let themselves down with details like rotten wiring and hose clamps... don't get it. ::)

I've never had a problem with the jubilee clips from auto or hardware shops. I agree with Terry, they're perfectly OK on proper rubber fuel hose. May not be on that cavis benz stuff, but that's rubbish hose anyway in my opinion.
I haven't seen those skinny little OE jubilee clips for ages. Are they still available? I have a vague recollection that they break pretty easily.

Tim's 3C originally had those small clamps too, also long gone (may be one or two left). The ones on the fuel taps get undone and re-tightened whenever the tank has to come off for maintenance, so they wear out eventually. The spring clips on there now are much more tolerant of regular disconnection.

I've got jubilee clips on most of my bikes simply because they're easy to source. Gotta admit that they're not the best with the length of polyurethane hose I bought a couple of years ago. The 5/16" hose is a wee bit loose on the fuel tap spigots and the jubilee clips are a bit hit and miss at getting it to seal.

When cleaning the Dellorto carbs on my Benelli the other day (first time I've had the carbs off), I noticed there wasn't any kind of fuel line clip on any of the 8 fuel spigot/hose connections. The (black rubber) hoses were just pushed onto the spigots. Didn't seem to be a problem as there was not a leak anywhere.

One of the local  well regarded independent Motorcycle repair shops here use the plastic tie wraps/cable ties instead of hose clamps. Maybe not the right look for "show" on old bikes like ours where you can see the clamp but it works well. Actually very clean look as well, especially  if you can hide the little end piece.

Looking forward to taking the taps off tomorrow and seeing if any gunk comes out. There was a fine black silt when I drained the tank last weekend so I assume I'm going to find more when I drain it. The left hand fuel tap was so seized up perhaps there is some blockage that can explain the poor running at high rpm.

Will take the air filter off and check but I'd be really surprised if it's bad but worth checking. Can't believe I' I'm buying another set of plugs.

Try without air filter for a quick run to see if that makes a difference, the jetting might then be out or of course get better.

Do you switch the fuel off when you stop the engine? I do that religiously as I have heard of too many damaged engines due to hydraulic lock.

I think the tanks needs to come off, be much easier that way as the airbox moves forward. The vacuum hoses are on top of the carbs and are less that 5mm thick, sometimes there is no hoses. Just bolts plugging the holes, it's either bolts or bolted on spigots that the hoses connect to. Try just removing the 50mm thick rubber connectors between the airbox and carb and test to see if it pulls through the rough rev range?

Don't just rev it sitting still, test it with a ride. Seen some issues with carbs that don't show unless the bike is actually pulling.

OK will do when I change the tap.

Hit the freeway and tried rolling on gradually rather than grabbing a handful. The bike behaved up to 6,000 and beyond and just started to stumble close to 7000 which suggests that it may be fuel.

Lets see how it runs with new tap a d cleaner air filter.

Post by: Vince on January 21, 2017, 01:31
7400 is red line, ducking for cover but that's pushing it a bit. If Reds done the engine I suppose thats ok. I rarely go beyond 6 mostly. Dont you have cops over there?

Post by: Davo on January 21, 2017, 01:53
Really? I thought 8500 was red line  :o

But then, like you Vince, 6000 is about my limit. Rode it this week mostly sitting on 5000, occasional 4500 and 5500 just because, nice and stable but about 1500rpm behind the bikes in front of me  :laugh:

Will be doing an oil change tomorrow and checking the shim gaps and having a squiz at the cam lobes and buckets with a fair degree of trepidation.

8,500 is real redline. The one thing I learnt about this bike 25 years ago.

I take it back though, still not 100% at around 6000+ but better than it was. Have new plugs for when I do the other changes.

That sounds a out right Davo

One of the local  well regarded independent Motorcycle repair shops here use the plastic tie wraps/cable ties instead of hose clamps. Maybe not the right look for "show" on old bikes like ours where you can see the clamp but it works well. Actually very clean look as well, especially  if you can hide the little end piece.

Nice idea

The clear hose had only been on for a few days.

The green hose is today's replacement and these are the stand-in clips until the Piet approved ones arrive. The others where chewing up hose.

Red line on the Laverda triples has always been a bit of a mystery. It's obviously not the 6500 shown on the tacho because the engine is only just hitting its straps by then.

Without dragging out a dyno chart, I think peak power is around 7600, plus or minus a bit depending on state of tune. But as with most engines the power drops off rather steeply once it's past the max, so there's not much point going beyond 8000.

Tooling around below 6000 on a Jota is fine on suburban streets. But if I want to have a bit of fun on country roads I like to crank it up towards 8k.

If I was going to paint a red line on the tacho I'd put it at 8000. With Ignitech ignitions you can set a rev limit. I have mine set at 8500.

Put some drywall screws in the tank along with some paraffin and give it a really good long shake and then rinse with more paraffin,  or whatever is in the tank will clog up your carbs and they'll be back off to Red.

Keep shaking to just before you collapse, just do it till the kero comes out clean. Hopefully its not big flakes. You will then have to decide if you got it all or if its a regular event. Then it's time to do a seal job. Thats if its rust and not just gritty crap. If its rust it has a tendency to reappear. If you go liner you must follow the steps to the letter, even more time than specified. It pays to do it as well as you can

Inline filter will catch the downstream fines that are not caught by the larger bits that will eventually block the coarser filters above the taps causing fuel starvation anyway. You can also end up with pinholes through the tank. The tank needs to be sorted if it is rusting inside.

No because one tap stops flowing - the one with the higher pipe when you get to the bottom but in reserve position in both taps fuel goes from the bottom of the tubes where the *hit is - the higher pipe is your alarm bell - then turn both to reserve 

Jota is a beaut compared to stylishly designed but infinitely flawed RGS tank - where there is capacity below both taps  :-\

The bike ran nicely all the way to York which is about 100km outside of Perth.

I still reckon there's a fuelling issue of some sort but need to ride more to be able to define.

Although I was going on about there still being a rough spot north of 6000 I didn't the notice it today because I never went there even at faster than legal speeds.

Special mention for the brakes on this beauty, they are pretty impressive for a 40yr old bike.

So managed to get home but the bike started missing over 4,000rpm, seemed to happen progressively, starting at around 5, then 4500 and eventually it wouldn't run smoothly over 4k, even though it was faultless below that.

Pretty sure something is causing the plugs to foul but it's going into ProTwin on Tuesday so they can deal with it.

Was a nice ride regardless :D Was also nice to be able to close fuel tap without a set of pliers  ;)

Bike still in the shop.

They test rode it and apart from the misfiring Mitch also said he heard "a horrible noise" from the engine at around 4000rpm - he found can chains a little loose so tensuoned them.

He also pointed out that I had resisted plug caps and resisted plugs so he's swapped out for hotter, unresisted plugs, all of which should give a stronger spark.

Taking on the front forks today...

Well the boys are into Ignition software now.

They managed to get it running well up to 6,000rpm but after that they felt that it just runs flat at that rpm - they asked me if the rev limiter was set there it was so consistent.

They have now downloaded the Ignitech software and are trying a few things, although I doubt that's the problem but hey ho they are used to troubleshooting old bikes so lets see what happens!

Worth your shop checking volts when running at 6000rpm.  Ignitech is very tolerant but needs 7-18v max
If you used the map Red sent you for a 180, I very much doubt that is the problem

Post by: cbertozz on January 25, 2017, 10:45
Well apparently it's all sorted now. The bike is now pulling cleanly past 6,000rpm without drama.

They used the Ignitech software and reconfigured it (don't have any details yet). They started using the map that was on the bike and then tried the one that Red sent me.The issue was present with both maps.

Justin asked whether anything has changed on the bike apart from the coils, thinking that that alone shouldn't be responsible. However the coils are the only thing to change.

(Just as a footnote Troy Bayliss had Justin build and tune Mike Jones's bikes when he started his new race team last season)

Bike back. Running great. Tried winding it up a little bit and it pulled strongly through 7,500, not a hint of a hiccup.

The bottom line was that the new coils needed the ignition dwell time changing (longer dwell time) they finessed it a bit as well so runs well from idle.

The forks are also back in commission, the sports valves weren't re-installed correctly so that's all good. The guys overtightened the steering head which was quite unnerving riding home; easy fix.

Carbies leak fixed, just a blob of sealant on the oojimaflip. Ignition wired properly now as well.

Not sure sorry, didn't get into it yesterday. I'll post back when I get a chance to setup the laptop. Keen to ride before it's into the electrician for a week.

send me the map, want to see what they have done as don't actually believe that was the issue
modified map I sent you already had increased dwell time programmed in

What is dwell time? The amount of advance?

No, it's the amount of time that the coil is energised.

It's easier to imagine if you think of an old points type ignition system. Power is supplied to the primary (12V) side of the coil via the points.  The spark is made when the primary voltage is cut as the points open. Dwell is the amount of time the points are closed, allowing current to flow into the coil. Coils have some reluctance (a bit like damping) so it takes a little time for the coil to come up to full voltage (saturation) after the points close. If the dwell is too short, the coil won't reach saturation and won't deliver a good spark when the points open.

If you think about what the points are doing, you'll understand that the dwell is not actually a fixed time. It's a number of degrees of crankshaft rotation. As engine revs increase, the dwell time gets shorter. It may reach a point where the dwell time is insufficient and coil performance starts to fall off. In that case the dwell can be increased by reducing the points gap.

Electronic ignitions do basically the same thing, except the coil switching is done electronically and the dwell is set within the program.

Dwell time is also dependent on battery charge. A poorly charged or under-rated battery means you need a longer dwell time to ensure the primary coil is fully charged. If the battery is unsuitable for the job the ignition will suffer and break down at higher revs as the dwell time shortens.

Hooked the bike up to the laptop (praying it didn't corrupt the map on there. Also to Davo's point, the battery was fully charged so that wasn't the source of the problem before I took it in.

Now the valves in the forks are working I took out the spacers, and I put a tiny bit more fork oil in. Found that one of spacers had jammed in the tube, did wonder what was up with the front.

So looks like a change from Auto to Long on dwell setting did the job
Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: redax5 on January 27, 2017, 19:50
advance map has been changed as well
he has set the base advance at 3 degrees which is telling the box that the ignition system itself has been set at 3 degrees off of TDC which is not correct

base advance on the Ignitech set up is to allow for a standard ignition set up like a Ducati Kokusan inductive pulse ignition where the leading edge of the lobe on the rotor is set at 6 degrees and the total duration of the lobe is 30 degrees which gives the Ducati a total advance of 36 degrees
If you installed an Ignitech ignition on this Ducati and used the standard inductive triggers you would set base advance at 6 degrees which is telling the box that the leading edge of the lobe is in fact 6 degrees away from TDC

that is an incorrect setting on the Redax/Ignitech ignition as it is timed at TDC so the actual setting should be "zero" though I do set the base advance at 1 degree as I presume very few people will be able to accurately position the engine at exact TDC when installing the ignition

changing the dwell to "Long" from "Auto" is setting the dwell to the Ignitech default of 3,000 microseconds and a dynamic addition of 12%, this is the default Ignitech setting for coils with a rating of over 2 ohms
if it works on this engine then fine, is doing no damage

Post by: Dellortoman on January 27, 2017, 21:29
I presume very few people will be able to accurately position the engine at exact TDC when installing the ignition

Yes. When I set these things up, I try to get the base as close to TDC as possible, but rarely get it spot on. After positioning the rotor, I set the Ignitech program to zero advance, fit a degree wheel and strobe it to see where the base setting has ended up. It's usually somewhere within a couple if degrees of TDC. Note that the Ignitech won't accept a negative base advance, so if I happen to get the rotor positioned a degree or two after TDC, I'll re-set it and try again. I'm happy with anything between 0 and 5 deg.

Giving Carlo's tuning bloke the benefit of the doubt and assuming he's familiar with ignitech systems, perhaps he strobed it and found the base advance to be 3 deg. It would be worth asking him. If he didn't actually measure the base advance and arbitrarily changed it to 3 deg (while it is still 1 deg) then the entire advance curve will be 2 degrees retarded.

When I set up the advance on my Jota, I did it on the dyno, setting the advance for best engine performance at several different engine speeds. I ended up with a curve almost identical to the "before" map in Carlo's post. I note that the "after" map brings the advance in significantly earlier through the rev range.  It would be interesting to know the reason why he did that.

Carlo. I'm not saying your tuning guy is wrong, but it would be worth asking him why he did what he did. He may be a tuning guru and we could all learn something from him.

Show him this thread and ask for a comment. That's why this stuff is so useful to all. I also think I noticed the column where there is engine rotations before firing, this is one of the reasons why this ignition is so good on Laverdas, having it rotate a couple of times before firing helps with Starter sprag issues, not so much with 180s, more so with 120s. Even though I have heard mine squeal a couple of times from slipping, caught my attention and got a set of springs immediately.

Dunno about your clutch cable routing - I may be wrong but I don't think it should run along the outside of your motor.  Looks like the top bend out of the clutch lever is too sharp.

Sorry about the state of the paintwork - it did get done eventually.  I may be wrong, but this was my routing - up over the shell of the headlamp and then curving down as gently as possible between the frame and the tank on the RHS, and then under the frame and to the left of  the carbs.  You can see the cable tucked out of the way in the second pic.

Carlo - does your cable run past (and in front of) the steering head before looping back along the top frame tube?  Can't tell from your photo if it routes past the steering head on the clutch side rather than the throttle.  The latter is preferred.  Think Reggie has picked up on your cable diving down rather than across the headlamp shell...but this may be because of the angle of your bars?

It also pops out in front of the cambox rather than behind

It is routed past the steering head and the down under the tank below the RHS tank stop.  The biggest curve brings it out over the far side of the cam box.

The good thing about you eagle eyed bunch is that when I'm looking at  this stuff I spot other stuff. Note the frayed cable cover in the picture, starting to expose the wiring.
edit: discovered was just a blob of brown stuff that looked like a worn cover, when I went to tape it,.

The clutch cable is loose enough to jiggle on the engine side and it moves on the other skde but it still seems to be wearing cover off the clutch cable.

Do you use cable ties to help guide the cable? Seems like if I make the cable come out over the engine I will be bending it in a way that restricts movement. I'm assuming that length of cable is an issue here anyway. I have to get the mechanism which adjusts the tension at the bar replaced as its seized and I've lost the spring out of the mechanism (that's what that ball bearing early on was from!).

Well your cable seems more or less right at the top end - it initially looked to me like the top bend was very sharp - not the case it seems.  I think I used a large cable tie set loosely around the frame spine to keep the cable in position.  It could be that your cable is too long.  Mine would have been custom made because I used a Yamaha clutch lever and perch, but I think the routing (behind the motor) was correct.

For those gadget geeks amongst you I recently bought a Samsung Gear S3 and I discovered I could make my own watch faces.

Have done a couple so far, no prizes for guessing what design. ;)

The Laverda logo lends itself nicely to a watch face.

First set of filters have arrived but 3mm too big, although haven't tried to see if I can make that work somehow. (Any ideas?)

Red did advise you the pod IDs were too large.
Fit is critical if you want hem to stay in place.
Either buy the right size or get someone to turn some adaptors that screw on to the rear of each carb. This area is threaded to accept screw on bellmouths/velocity stacks.

Yes he did but was too late by then, my bad. It's fine can return, and have bought some from same place Cam got his.

Thanks for the heads up on the adaptors Will see whether protwin can help with adapters out but no dramas either way.

Fairings are a lot of work to fit, especially if you mount the instruments in them. I have had 2 types on mine. The TT Montegi full fairing and now an SS bevel that I fitted using the mounts from the first one. Useful back when you could cruise in the bush at 140 plus. Doest happen these days with the attention that would cause. Much easier to do the Blual :sp" or maybe Guzzi nose cones, much less effective but very sexy looking.

Horrific thread-bomb :o

Anyway, so still not 100% with my forks and doing some reading on the forum I discover the existence of an item called a "spring guide" (Thanks Cam)

Apparently these are this metal tubes that sit over the spring and keep it compressing straight and stop contact directly with inside of forks.

I definitely don't have any installed.

Also checked the sag again and it's too much so will have to reinstall some spacers, albeit smaller. So will have to find something at hardware store that will do the job.

The last time one of the spacers I had been using got stuck inside the fork leg on the thread causing  the spring to remain compressed. Loathe to put those spacers back in in-case that happens again.

2 easy ways, thick walled plastic conduit cut square to size. Walls need to be 4 or 5mm thick with stainless washers top and bottom loose enough to fit into the fork with smaller than usual holes to support the plastic, or just a stack of the same washers. Bevel Heaven used to sell Maz only fork cap with a built-in preload adjuster.

Measured the washer in there and ordered a box so I can fix at the weekend.

Look at this on eBay http://www.ebay.com.au/itm/262039965213

So will be able to add the preload 2mm at a time, which should be around the equivalent of two turns of preload on a normal fork adjuster (Very roughly), starting at 8mm and goinff from there.

Whilst out yesterday I found myself thinking about a fairing again.  Not sure whether I'd look at the full top fairing or try Reggie's approach. Something else to research.

I quite like the HoleShot fly screen, headlight mounted. Looks a lot like an earlier Buel fly screen. Decent brackets, I had to modify them to fit it to my 79 1200 Mirage. Later I moved it to my 79 CBX turbo bike, where it presently remains.

for such a little flyscreen, it is surprisingly effective, generates smooth air flow and raises the air flow significantly.

So fitted washers to forks and they already feel better just at static, and I have a usable 39mm of sag at the front, the rear at 25 so will reduce preload a tad.

Fitted the bigger hoses and more traditional clips. Will be interested to see whether the larger diameter pipe has any impact at all that I can discern.

Also fitted the low tone Voxbel under the tank. Don't really like two horns on display so the other being tucked away is fine. Thank God I was persuaded not to fit the fog horn.

Fuel flow is limited by the tube with the smallest radius which is through the tap so the bigger pipe will not make any difference.

I've been riding with ear plugs for around the last 15 year. I've tried everything from custom fitted protectors to builder bulk plugs. To date the cheap disposable type have worked best.

That's said the different foams filter different frequencies of sound and different plugs achieve better results for some bikes than others. The ones I use for racing seem to cut out some of the Laverda bass and let some of the mechanical noise through so I was considering looking for a new variant.

Anyway I saw these advertised and they intrigued me. Iike the idea that they are completely passive but with some tech (which I don't pretend to understand.

 So will let you know how they work when they arrive. At the very least they'll be good for flying.

Be interested to see how they go. Not cheap so would want to be very good. I have started trialling ear plugs for the first time ever due to the very loud wind noise of my new Neotech helmet compared to the previous Multitech despite claims that it is very quiet. Have tried moulded plugs and disposable foam and both seem to get rid of the engine sounds I wish to preserve but still allow the "thump thump" of wind noise.

So having put the new spacers in the bike seems to ride better. There's still a bit of shake in the bars on rough roads - haven't had a go at adjusting valves and bit sure where they were set since protwin had it, so likely needs less rebound damping. I turns and begaves itself in sweepers. Tried pressures at 35F and 39R today and softened off the rear a bit.

Anyway still avoiding the rain!

Interesting comment. Studies done on Moto Guzzi Le Mans showed the exact opposite. The bikes tested breathed far better and had a better power curve using the stock air box and filter compared to pods of various types. So maybe it is the placebo effect, feels better because you think it should.

Mind you, I haven't seen comparison studies done on Laverdas. And yes, I have pod filters on my triple.

That's what the conventional wisdom used to say, airbox good, pods bad with Dels. It was always the same with 3 into 1s producing less power than a Jota system. Give the pods a go and tell us what you find. Its mostly pods with Miks as its hard to fit and use the airbox.

I'm just basing it on past experience with several Harley and modern bikes. Like the look/sound better ( hold your derision). If not I'll put airbox back.

Will give you a little more to clean/polish, fuel stand-off from open carbs causes a horrible mess.

Feels livelier because it's louder, same effect as with open pipes... dyno will probably show there is little to no difference, might even fuck up performance depending on what type stacks or pods are fitted!

I agree with Grant, and matches my personal observations tuning carbs on Laverda triples.

I would suggest stock air box shell, gutted of any of the baffles (if even still present) and cut down a thin flat K & N filter from a Honda Valkyrie, silicone beaded into place. Great air flow, excellent filtration, cleanable.

Smashed out a few hundred km again today, and tested suspension on bumpiest roads I know.

Bike ran well apart from a weird glitch a couple of times where the bike struggled to get going when rolling on hard in top gear at 120kmh. It was different from the electrical issue which felt like a rev limiter. This felt more like it was struggling to get fuel. Only happened a couple of times after stoping for a coffee and wasn't able to replicate. Hopefully just a glitch, reminds me to get those inline filters on.

There can be some long straights between the bends here!

Do not eat BBQ sauce ...... I worked in a sauce factory once, have never chosen to eat BBQ sauce since.
Except the time the stupid girl at the fish shop that put BBQ sauce on my hamburger. I ate it, but cringed on every mouthful.

I'm not going to go into the details, but some of the things I saw go into BBQ sauce was a wide variety of shit...... that bloke on the TVs that eats all those, bugs, goats balls and deep fried frogs shit, would gag on a BBQ sauce line. Do not eat it .......... I feel like puking now!

The fuses on the table would be healthier for you than the BBQ sauce.

I agree with Grant, and matches my personal observations tuning carbs on Laverda triples.

I would suggest stock air box shell, gutted of any of the baffles (if even still present) and cut down a thin flat K & N filter from a Honda Valkyrie, silicone beaded into place. Great air flow, excellent filtration, cleanable.

Paul LeClair

Ok so there's basically nothing in here apart from that thin foam filter (with heavy metal frame).

So putting on pods is really only a cosmetic change? (That might make performance worse because of the 'turbulent' air. Well we'll soon see.

I did try and for the 'wrong' ones but they sit too high and contact the tank. I've got a set of the cheap ones Cam mentioned and a set of K&Ns on the way.

Too kind, it's amazing what a phone can do these days, add a filter and you're off! There's so much stuff to photograph that I have to remind myself I'm supposed to be riding. One thing I rode past today and regretted not shooting was a make-shift sign for "LOT 101", I'm a 1984 fan.

Now I want to know what horrors are in BBQ sauce. C'mon Chris, tell us the recipe.

Can't but loads of sugar and caramel ............... when making tomato sauce the tommies are all shit stuff the market won't accept. They go into a big centrifuge to sieve out all the maggots, bugs, spiders, frogs, lizards, leaves, shit, pips and skin. When the jacketed pans were finished cooking up the tommie sauce there is a crust on the inside of the pan, the sugar and caramel is added ............... the shit in the centrifuge has to go somewhere (puke), cooked to down and then sieved before bottling ........... hence the name BBQ I suppose.

Things may have changed since then, but not in my mind.

Anyway finay fitted the sidestand today. Thanks to Jotajoe for that :) (thanks Cam for spotting the side stand for me as well)

I probably should have cleaned it up a bit more but it might look out of place.  Anyway it will be a blessed relief not to have to check around with centre stand on shitty surfaces.

Fitted K&N pods tonight so we'll see how they go tomorrow.

To be honest I thought I was going to like them.better visually. They seem a bit small and they foul the side panel ever so slightly on the right side.

I have a feeling they may not be on for long as the airbox was already gutted and as Paul and others have pointed out, probably does a better job of letting the engine breath.

New grommets installed for side panels.

I've superglued a small plastic loop on the inside of each panel and will losely lockwire the loop to the frame which hopefully buy me vital seconds if they pop of

think your carbs are different as well Cam  :o
we use DNA filters, not a fan of the K&N due to shape and also these days, they seem to be made from a different material to what they were and tend to slip off too easily
probably made in China these days whereas the DNA I believe are made in Greece
not certain if that is a good thing or not

Only if you want there to be. The only reason my bike got all the mods was because it needed a full rebuild from bare crank and frame. You have the option of doing nothing and just riding the thing and enjoying it for what it is. No matter what you do to it you will never turn it into a modern superbike, they just don't have the ponies or handling.

Riding more than you ;)

Shoudl have done more research, assumed I could just pop them on and off I go.

For the record I wasn't after HP or speed. I love the way the bike goes, just wanted to see if it breather any freer but the previous setup was probably as good as it gets.

Also like the look of pods but purely cosmetic. Think it had bellmouths on prevuously.

Hey Carlo. Have you made some kind of bracket to support the filter or does it just hang off the end of the rubber connector tube?

Have 'made' a cat's cradle using cable ties which site nicely over the clips joining the pod to the connector and links with one over the frame. I've also put cable ties on the very end of the rubber connector where it sits over the carbies threaded port to help make it super firm.

I ran today without this stuff and it all stayed in place but I can imagine that without it it would all come apart on a really bumpy road.  I'd like something that screwed on at the carbies. Maybe will get something made. Anyway let's see how it goes, love not having the fugly airbox.

Still searching for another solution but resisting putting airbox back on.

Have to thank Piet for bugging me about those clips and hoses. The hose is thick and maleable but fits firmly and the clips are a breeze to use. Makes getting the tank on and off a breeze and looks good.

There was nothing immediately obvious other than a more aggressive sound and and a better spin up through the higher rev range, although that could just be the placebo effect. No popping, idling problems.

The airbox had been completely gutted apart from that thin foam filter and the connectors are the same. Taking it on a longer run today.

I had the same thing with the baps on the Cico so I drilled them out too and it seemed to fix that it.

They may do, but when I needed to drain the tank to do some repairs it took 10 minutes from around 3/4 full to empty running the fuel out through the new square taps. I can't see the engine at any revs using the fuel that fast.

Seriously I let most of your grumpiness through to the keeper but this takes the biscuit!

There are only half a dozen good roads in WA and if you think the plod doesn't know where they are then you're kidding yourself  :laugh: :laugh: :laugh:

There are actually a lot more than you think and obviously know about and I for one keep my mouth shut about them on public forums. I personally know of two of our boys in blue who have joined forums and kept their real job quiet until discovered. For that reason I never mention roads I ride on public forums. Just last week I was having a chat with a couple of guys at a servo who were about to ride out that way and had never heard of the road you mentioned. If you think I am grumpy, so be it. Getting sick of roads that used to be dead quiet becoming overloaded with prats on 2 wheels because the cops have moved in on their previous favourite

These routes are published in multiple places online.

Not every Tom, dick and Harry may know.them but the police certainly do.

Police and speed cameras follow the accident blackspots. People need to learn to ride. We see these guys rock up at the track who can barely get them around Turn 1 yet they can hoon around the countryside out of control.

What's her name? Not as well known as an 883 as a girls bike, but not far off.
Tidy looking thing though.

I swapped my ZX7R for a spin on a GSX1400 on Saturday ................. cracked a fat over the torque.
Need a gear to go fast ............ pick any and turn the twist grip. When we swapped back 1400 owner said he'd never changed gears so much in his life.
My comment was the opposite.

A mate and I are looking at buying a 4x4 truck from WA as a support vehicle for our upcoming trip to Cape York ............... there's a tubocharged GSX1400 :o over there for sale that I've been eyeing off for a while ........ very tempted, as freight home would be $0.00. 178HP and all that torque ....... phew, blows my mind just thinking about it.

The GSX1400 is the bike of choice for my sidecar riding mates. There was something like 14 of them that turned up to the Northcliffe w/e last year. And a couple more have been built since.
The Laverda sidecar has been retired and replaced with a 1400 as well

I've had mine for a while (98), here's what I learnt:
Keep a check on the fuel pump. Make a habit of putting in first gear and turn on ign and hit starter, you should hear fuel pump clicking away then go silent. Proves it works, they shit themselves at about 60K. I have added another fuel filter pre pump to hopefully stop the problem.
Fuel tap rubbers go every now and then, cheap replacement Saturday arvo job.
Cam chain and shims .... at 42K will be close to needing to be done. I change engine oil every 5K or so and has now done 62K and cam chain and shims are now due again.
You know when they need doing, as it sounds like a diesel engine. It'll come back from the shop nice and quiet again.
I strip all the bodywork off before taking it into the shop, saves a fortune.

If laying bike up for a while, I disconnect the fuel line at the tap and run it until it dies from fuel starvation. New fuel turns to shit quickly, and clogs up jets.

Mine has a Dyno Stage 2 kit, worthwhile I think, has 144hp at rear wheel on Dyno.

Speed wobbles: When powering on, watch for bumps in the road. I've had tank slappers rounding up other bikes that almost threw me off the bike, and at 180 it's a little unnerving.

Other than that, I've found these bikes great, just too small for my almost 6ft body on long trips.

So finally had the gaskets sealed up on gearbox so hopefully no more leaks.

Routed the clutch cable slightly differently

We trimmed the air connector pipes so they are now securely fixed.

Unfortunately discovered that the suspension gremlin I was chasing is actually the rear swing arm so will have to replace bushes or bearings depend on what it has - I have no idea!!! Can you tell somehow visually?

Ah, Cerianis, as per your lock stop query.
The same lock stop bracket is used for Ceriani and also Marzocchi yokes but they are assembled differently.
The bracket that located to the steering stem tube on the underside is bolted directly to the frame above the oil cooler area, whereas on Marzocchi yokes the bracket has a small spacer between frame and bracket (where the M8 bolt locates it to the frame).
If the bracket is fitted using the spacer when Ceriani yokes are fitted the lock stops barely if at all touch the lock stops.
If all is present and correct then maybe your bracket is bent or damaged.

Warn swingarm bearing are supposed to be detected with feelable play laterally with the bike on the centrestand and you pulling and pushing the rear wheel. That might need a solid whack with the palm of your hand to feel and hear any clunking as well. Works better with the shocks disconnected. This can be subtle, its not like they end up like a cock in a sock sloppy. Did you feel any knocking while healed over in corners.

Ye we put it on the centrestand and then man-handles the wheel and there is play (exactly not cock in sock loose but definite play). Didn't feel it in corners but when changing through the gears under hard gas, wobble from rear as the drive picks up.

Bike booked in for swingarm bearings next week.

Have got a weird mechanical clattering that starts to show up on short acceleration/deceleration runs, like rolling on and off over taking.

Thought it might be the sidestand on the exhaust so may try and find a better spring this weekend.

Will also try changing that rubber grommet for the bump stop.

Get the bike up on the centrestand and have a look at the drive chain versus the chainguard. Either a slack chain or a slightly out of true chainguard can cause that.

And early centrestands on bikes fitted with big bore collectors can have and exhaust v stand clash. Solved by either putting a bigger rubber stop on the rest pin or getting a crossbar with a bigger curve fitted to the centrestand.

Good points. I've removed the centrestand to have a look anyway, will eliminate that, and I will definitely check chain/chain guard and exhaust mounts.

hi, first thing to do with your swinging arm is to slacken the swinging arm pivet nuts then pump the swinging arm full of grease until it oozes out then re torque to ft and your problem my disappear, i do mine every winter.
 the rattle is normaly a slack chain i've found they are very touchy when it comes to tension but these are just my veiws you can buy other makes.
hopefully my pic will work

Ok Well I will definitely check chain guard and alignment again if the noise is still there after running without the centrestand.

The swing arm thing could quite possibly be grease related as the previous owner warned me about lack of grease and with everything else going on I've not done anything with it. I'm going to get a new grease nipple today and pump the bugger full of grease and hope it's not too late ;)

What do you torque it to? I've done 80nm (59ftlb) as that's what I do front wheel on race bike, don't want to go too tight I'm guessing.

If your swing arm bearings are knackered, pumping grease in will cure it, for a short time by taking up the play. It won't cure the wear which will soon make itself evident again.

The swingarm wasn't tight enough either, didn't even have 30nm so would  a loose swingarm mimic worn bearings? Bike feels great now, just took it out for another shorter but more aggressive run.

hi, not sure of the torque numbers but FT means fucking tight, if your bush's/bearing are worn then replace but i suspect if the spindle was loose and dry then you may have saved yourself a shit load of money ;D. or do as others do a chuck five figures at it and turn it in a hybrid
 the gold on mine was matched with a new side panal from Richard Slater who kindly lent it to me, the code is ford capri yellow and you must use a yellow primer.
don't know why but mine is very free revving compared to my others.

You want to be sure the swing arm is properly shimmed up between it and the frame.

Tim,

I love that photo!
I don't know if it is the colour or what, but the engine seems to dominate the bike.
This is how a musclebike should look.
Great!

hi, not sure of the torque numbers but FT means fucking tight, if your bush's/bearing are worn then replace but i suspect if the spindle was loose and dry then you may have saved yourself a shit load of money ;D. or do as others do a chuck five figures at it and turn it in a hybrid
 the gold on mine was matched with a new side panal from Richard Slater who kindly lent it to me, the code is ford capri yellow and you must use a yellow primer.
don't know why but mine is very free revving compared to my others.
here's a pic of me 750 same paint / primer but just looks different :o
safe riding andy

My dad had a yellow ford Capri in the 70s :) there's a local guy who does good work locally on old bikes (Davo's used him). I'm torn though, was thinking of returning it to black but Laverda have some great colours and I'm tempted by green and also one of the blues I've seen.

Bike ran really well today, pulled hard through the gears. Started to work it up over 7,000 rpm and although there's a slight stutter at 7500rpm it pulls through it. It's spent very lite time at that Rpm so let's see next time.

Essentially I was recalibrating my own feel for how I could push the bike. I hope I haven't nannied it too much since it was rebuilt.

More importantly it rode really well at speeds that I would.run on a modern sportsbkie, albeit a bit bumper ;)

Tried taking out some rebound compression to 'soften' the rear but it actually made it worse. Put it back in and the bike felt better again. Need to back off the front next time before I back off the rear.

Running 34f and 36r for tyre pressures. Will try a little higher next time to see what happens.

Post by: Dellortoman on February 28, 2017, 02:53
Not a difficult job to replace now that you have it apart. Well, almost apart. That nut has to come off.

You'll need a rattle gun and very deep 36mm socket. I don't think you can buy them that deep. Easiest way to get one is to buy a normal 36mm socket, cut the business end off, find a suitable sized piece of pipe that will fit over the end of the crankshaft, and weld it in between the business end of the socket and the 1/2" square drive end. Voila! A socket as deep as you like.

Or you could borrow one from someone who has already done that.

BTW, I think that's a left-hand thread.

Once the nut is off, hook the seal out and press in a new one.

I didn't check the oil but they've changed the oil before and we've not experienced this problem. Will check once it's back together again. We've been chasing the leak almost since day one, although the gear selector cover was also leaking.

The alternator cover gasket was leaking oil into the outer case and the wind would have been whipping that up through the top gap. I agree it could have been over filled, but when they did the last oil change it was good and it's the same guy working on it. Who knows?? Anyway on its way to being fixed.

Forks open again tonight. Now five clicks of rebound compression now, not 15.

Topped up fork oil - last time I didn't put enough in, was reading the wrong scale. Not sure WTF I was doing.

Took it for a spin, rides better, better damping with less harshness and pulls up better too.

Yep compression dampinh already low. Personally I've never been convinced and eventually I'll replace with a set of gold valves, get it setup perfect and never touch them again apart from servicing. I reckon they were damaged because they weren't fitted right after a different shop (not protwin) had them off the bike.

If I ever switch to clipons I might consider them again as I'll be able to use the fork cap access but nothing positive to say about them in their current state.

No just a trick of the light. Something on my to do list Cam!

Drained forks again today, put 5W back in and adjusted the suspension again . First time when I put it all back together again the front was bouncing like a Pogo stick so off with the bars again and this time put back the rebound damping I'd taken out when I had too much 10w in there. Measured it all properly this time and seems to have paid off.

Also fitted the SmartTurnSystem today. Wiring was pretty straight forward. The unit sits nicely in the nook under the frame and  front/above coils.The only issue is the foam pads in the switch which aren't quite right yet but will see if they bed down. Looking forward to testing tonight.

Fitted new speedo cable in an attempt to reduce the bouncing needle, the old cable was pretty knackered.

2000km trip coming up next week so gradually sorting everything.

Something not right even though it tests right up until engine on.

I even tried removing the unit from the bike and mounting it on a fixed (vibration free) surface just in case the rumbling idle could be impacting it but no difference.

Tried simultaneously running earth and love to other points but same result.

Going back over wires again

Earth and love isn't enough, what you need is electricity!

I am not convinced that vibes are the culprit. I would be going towards the 'what changes electrically with supply when I hit the button' scenario.
Perhaps getting the power from somewhere else - just to test. Perhaps direct from battery.

I agree that was clutching at straws.

I ran a wire back to negative on battery and I ran a wire to a guaranteed supply, still.no dice when the engine starts.

Nothing can be drawing current from it when wired to battery and the multimeter still shows 13v on the power. You'd thing wiring to negative terminal would also rule out earth.

So I'm left looking at what other areas are in the equation that only happens/changes with the motor running.

The only thing I can think of is that the alternator starts generating juice at that point which is going to the regulator (?). I seem to remember Brett suggesting the regulator was wired wrong but we never got into it.

Going to go over Cams wiring diagram see if I can find any clues.

If you've got this unit wired directly to the battery and it works until the bike starts. I'd guess it being affected by EMI from the coils.

You might try to shield the unit with some tin foil to see if there's any improvement.

I was working with a customer using a Tesla Coil last month when my tablet touch screen stopped working, seems it was due to the EMI field from the coil.

Well thats an intersting thought. It was mounted right next to the coils. Although it continued to do it when it was a short distance from them as well when I had it sat on a bin next to the bike, but would have still been within 30cm. Dang back in Sydney at the moment but will be back mid-week so know what I'll be trying!

EMI (electromagnetic interference)

EMI from spark plug wires can cause erroneous signals to be sent to engine management systems and other on-board electronic devices used on both racing and production vehicles in the same manner as RFI (radio frequency interference) can cause unwanted signals to be heard on a radio receiver. Engine running problems ranging from intermittent misses to a dramatic loss of power can result when engine management computers receive signals from sensors that have been altered by EMI emitted from spark plug wires. This problem is most noticeable on modern production vehicles used for commuting where virtually every function of the vehicle's drive train is managed by a computer. For many reasons, the effect of EMI on engine management computers is never predicable, and problems do become worse on production vehicles as sensors, connectors and wiring deteriorate and corrosion occurs. The problem is often exacerbated by replacing the original ignition system with a high-output system.

Cool. Will do. You are very lucky to have those roads on your doorstep. Attached a pic of Saturday's ride.

The roads were in pretty good nick all round apart from one bend on the way to Manjimup, there was a bend with quartz gravel (i.e invisible) a couple of inches deep. A guy on an Indian going the other way had clear hit it and his bile was in pieces, he was in a bad way.

I have a set on the Pantah 38mm Maz forks that are adjustable for both angles and height. From Gowanlocks and considerably more expensive that non-adjustable ones. Look at fitting them above the top triple tree if your fork is through enough, it can be done now with clip ons if your back complains. Speeds up the steering but reduces ground clearance and changes how the stands work

Best you forget that one pretty quick.  The Ceriani yokes as used on the triples by Laverda were not bored parallel to the head stem, never heard of Ducati parts being thus made.  Of course, it only depends on the size of hammer you intend using, you may even persuade it to fit... ::)  The Ducati item isn't cranked either, will lower the front end by about 15mm.

Only 38mm Ceriani yokes used by Laverda that were bored parallel were fitted to the 750SFC.

Doubt you can.  You can raise the forks by 25mm through the yokes without your mudguard tangling with the exhaust (CHECK THIS FOR YOURSELF!) but that isn't really enough to mount the clip-on IMO.  Otherwise you'd have to throw away the standard headlight 'ears' and use aftermarket tat which never looks good.

So as usual started a project with a voyage of discovery.

There's a simplicity to these bikes that you only start to appreciate when you begin to pulll them apart.

Started to install Clip-ons and the new headlamp bracket yesterday, as well as the steering head cover and fork caps with access to sportsvalve.

Discovered that the caps that sportsvalve provided aren't actually drilled large enough to take their adjusting tool which is disappointing to say the least - they are sending new caps. How does that happen??

Anyway easy process until I removed the tightening nut with built in crush tube or whatever you call the extended tube that extends below the nut. The stem appeared to rotate at one point which it shouldn't do apparently.

Anyway, worked out that I hadn't broken anything. Should have put the bike up on a block of wood to increase the centrestand height from the beginning. Once done I could move the stem to get the nut back on easily.

(https://lh3.googleusercontent.com/al9KA_x_vR5DH3vT_VOFsicSEwOkk8Yt9XclMiBlTdUwepDVy2G0j31xbhLY2ymZ0ncNsd6S35xJ8McbMqgMn33hHVmkOfZLEHj1vFYh0HHGU-mg67VGU6A8YY2cEKdvO0DYXg=w1081-h811-no)

That said I don't really have any choice but to pull the front end off to see why the stem rotated because it's now not true when I put the top triple back on, so can't put the bug chrome nut back on.
Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: cbertozz on March 19, 2017, 09:28
Well had the front end off  :o

All seemed ok, bearings in good nick, added some grease for good luck. Put everything back and made sure stem was properly seated and tightened.

(https://lh3.googleusercontent.com/_kXYxd-YEkJNCRR2bxusKtMVoQLtei1zVMqz9f4N-4AzbC2l8BMfSxjpk0Wg1eIRj3BjGgv-bpbk4A-sOJ087ZbmZzazJFTkzDirAr0t4B7c5SxZ2L0XRyDl-lLV9u4e20ia7Q=w1081-h754-no)

I suspect I will have to try the Tarozzi bars as these tingates are low, which feels good but reckon some extra height would be good. Anyway while I deck around with the suspension they're fine.

Front end felt very solid, no shales, and like the purchase the slightly wider angle on bars.

The headlamp braxket is pretty average (as predicted by Davo) so will keep an eye out.

Also not sure I like the gap where the Jota bars used to go through the dash clamp, looks worse than I anticipated. May be better when I have the higher clip-on as it will balance out better.

All this discussion​ of the hybrid front end I think I'll see if I can't get back to a full Ceriani setup..

I've seen them where a piece of chromed handlebar is cut off flush with the sides of the instrument mount.  Put a couple of black plastic in the ends and it looks pretty neat, or even have a piece of bar turned up to fill the hole.

Still digesting my first experience pulling the front end off a motorcycle.

One thing that has stuck with me is how little is holding those forks in the clamps.

With a set of Jota bars you kinda had an emergency backstop but with clipons those pinch bolts are it right?

I don't "see" mechanical stuff easily but with the top clamp firmly secured to the steering stem if you hit a big pothole it's possible that the forks could move in the clamps, or the Clip-ons could move.

Anyway it was good to torque everything up at least although not the pinch bolts which are just fucking tight.

Fuck me you don't half overthink things.
The stanchions have never moved in the yokes (without me moving them) on any of my triples in 38 years of ownership.
The same forks and yokes were extensively race tested in endurance, road and short circuit races with forces exerted far in excess of anything you or I could generate.
Just do them up properly and ride the thing.

Always wondered what would happen if that little screw that holds the headlight on came loose. I found out tonight going over a ramp.

Headlight popped out of its shell but fortunately the wires stayed connected so I was able to stop and regroup.

Can't see any evidence of a leak but there must be one. I expected to see something on the garage floor but no evidence to date.

Going to pick up the Tarozzis tomorrow.

So this allen bolt is inside in the bottom of the forks? Will go find a diagram

So #27 and #28, hopefully just loose, or maybe doesnt have a washer. If it doesnt have a washer whats an interim fix until I can get one?

Ye I've filled them from zero and put around 320ml so far but when I put the measuring stick in there's basically no oil on it  but assume its sitting below the valves? not sure where its suppoed to be but that would mean a very big air gap.
Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: Davo on March 24, 2017, 13:22
From memory 380ml is the recommended amount for Ceriani forks. Prepare for the dissenting comments. The other method is to measure level from the top rather than volume of oil. There are many opinions on volume v level.
Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: Vince on March 24, 2017, 13:28
Air gap is measured springs out and the fork fully bottomed, collapsed. I jack mine with a trolly jack till there bottomed and set the gap with a turkey baster at 130mm. Pump the forks to remove any air after adding the oil, DONT JACK IT OFF THE CENTRESTAND. Hope you still have a centre stand, handy for this stuff. Preferred method over volume out of a bottle

Thee hundred mills in my forks (RGS) then I pump away on the forks like milking a cow. When the 'swishin'g noise stops, I let the forks sit fully extended for a while to let the fluid settle then check the level with a steel tape measure to make sure they are the same.

You reckon your oil leak was bad? One of my Gazi shocks spewed oil all over the IFOS Laverda display, not bad for a brand new shock that has travelled a total of 1.5 hours.

In retrospect, I should have gathered up the oil and poured it down the spark plug holes to free the seized pistons.... this Laverda stuff is character building.

No, until the 1979 model year the horns were mounted to the lower yoke, or 3Cs had them mounted on the oil cooler (if an oil cooler was present).
1979 onwards were mounted at the front engine mounts, right in line for all the road spray from the tyre.

Yes, see them now.
Your bike, you can put them wherever you want.
Will last longer if kept away from the road spray flung up by the front tyre though.
Voxbells are a crappy design and are notorious for rusting up inside and stopping working.
On my Corsa, when the second set of Voxbells stopped working I ended up fitting a pair of Fiamms inside the fairing and left the Voxbells down by the engine (but disconnected) just to be period correct.

well you can see them cant you???
so that makes a noticeable difference,
you cant see any of the other stuff, carbs excepted perhaps.

If you really want a noticeable difference take your bike in its known good condition to a dyno house, and be prepared to either, take a lot of jetting, needles, emulsion tubes and slides with you and swap them out (carbs off every time)  after your 2 or 3 dyno runs, for replacement's, or do a couple of dyno runs, return home and do the same at your leisure and then return to the dyno shop for another 2 or 3 runs. Repeat maybe 5 times or even 10, and you have a perfect set up, but only if originally you had correct values of ignition timing, valve timing and clearances.

Post by: Dellortoman on March 30, 2017, 00:08
... (carbs off every time) 

Blimey, you've been doing it the hard way Clem. The carbs don't need to come off. I've done dyno tuning runs with both DellOrto and Mikuni, and never took the carbs off to adjust jetting.

Actually, with the flimsy mounting hardware on DellOrtos, it's likely that removing and reinstalling the bank of carbs will upset their balance, so they're better left undisturbed during tuning operations.

With DellOrto carbs, main jet swaps are dead easy with carbs in place. It's also pretty easy to pull the slides out for needle adjustments (middle carb less accessible than the left and right, but still do-able). Emulsion tubes can be removed/fitted with carbs in place, but I don't know why you'd want to depart from the standard AB265.

With Mikunis, needle changes in situ are easy. Main jets also do-able but not as easy as Dells because of the 4 screws holding each float bowl on.

Main pain in the arse is working on an engine that's just had a sound thrashing on the dyno and is still scalding hot. Cotton gloves with the finger tips cut off can be handy in that situation - saves burning knuckles and backs of hands. Also, be careful with petrol dribbling over hot exhausts when you undo the float bowls. Use a catch tray. Best to let it cool for a few minutes too if your dyno guy is not in a hurry.

Post by: Dellortoman on March 30, 2017, 05:02
Yes, you're right. I was confusing myself because I remember taking float bowls off when the bike was on the dyno. I remember now that the centre bowl had a seized plug with the hex nut rounded off by a PO (2nd hand carbs) so had to remove the whole bowl to change jets. It was easier to get at the centre one by taking the outer two off as well.

I was stuck using that centre one because that's the one with the pump in it. I eventually found a new pump type float bowl on ebay.

So moved the horns but still to rig up a decent wiring arrangement.

Fitted them on and hooked them up and the mysterious fuse blowing problem returned, the one I had assigned to a loose earth on the horn last time. Turns out it wasnt the horn, it was the the handlebar switchgear that was shorting. I noticed on the old bars that there was insulation tape under both sets of switchgear, and with the new clipons this was no longer there, which I thought was for grip for the unit but now it seems it was a pre-existing problem that the tape was covering for. (cue all the shouts to get the wiring sorted).

Anyway, taped under the switchgear and now no shorting but will get it looked at. At least now I have something much more specific pinpoiinted.

reply 708

in a way you are right Cam,

 but I base my choice on a few things, at the dyno house, everything is hot and bothered, so burnt fingers are the order of that game, the dyno is charged by the time your bike is on it, parked or not, and there is little space when not on it, I don't like to have to borrow a single tool, even though I know the spannermen working at this shop, I can and did take my own "carbs off etc" tool kit, but still found that I was missing something, and the very worst was dropping a needle, which disappeared down a slot in the checker plate of the raised from the floor dyno installation, so 2 or 3 runs and return home, where everything is cool, I am not rushed or flustered, my carbs come off easily (Jota 120 inlet manifolds and rubbers) and every single tool is always available, plus getting the slide and needle out of the centre carb is just too fiddly, and I do like being able to actually see the pilots and mains when changing them, in situ is too much "by feel". I would and do however change the main jets in situ, if that is the only one needing a change, and for that you don't even have to remove the float bowls, if they "stick" that helps as well, but for all the rest, I take them off every time and rebalance every time.
CLEM
ps emulsion tubes? I tried the 2 stroke versions, which have a tiny raised "fence" at the engine side because that can help the motor tolerate rich settings more easily, as in slow speed and snapped throttle, and from that there might have been a torque gain, which in my view is more important than ultimate BHP, that didn't work!

Late evening run and the only place I can get a cup of coffee is BP!

We dont run much at night here outside of the city so when I hit a truly dark section of the coast road with no cars it reminded me why I was so comfortable riding at night in the UK. The headlight is remarkably effective for a bike of this age.

I'd never ride outside city limits at night, and frankly we see enough roos on the road during the day to freak me out.

Handlebars feel good in this position although I feel like everything is slightly crooked - need to find a way of getting everything exactly straight (bars, clamp, headlight, instruments etc.

Post by: Legs on April 04, 2017, 08:19
Here's an idea. String align your wheels so you know the front wheel is facing dead straight ahead. Then, holding one end of a length of string on the bikes centre-line right back near the tail light, measure the distance from there to the end of each clip-on. Once you are satisfied, punch a mark on each one for future reference.
That's how I did mine, seems to work ;)

The new Sportsvalve fork caps arrived  today so I can finally adjust suspension without having to remove the caps. Have reduced preload to 2 turns (out of 6) and have taken rebound  to 8 clicks on.

Have to find some decent black blade connector caps because there is nowhere in Perth selling them.

What are black blade connector caps

Hmm wasnt sure what to call them. The connectors for the wires joining the blades on the horn, two on one side, four on the other. Would be good to just have black to minimise their visibility.

Stripped the compression back to one full turn and rebound to 4 as a starting point. Will leave compression as is, and start adding on the rebound from there. I feel like the extra preload of the valves plus the depth of the caps probably puts the spring in a zone where it doesnt need a lot of damping but we'll see, this is a bit different from a track bike!!

Post by: Dellortoman on April 06, 2017, 01:38
The things on the ends of the wires that plug onto the flat terminals on the horns are normally called ( female ) spade connectors (the male bits obviously being the flat brass terminals on the horns). Various types are available, but avoid the crappy pre-insulated types. I buy uninsulated connectors and use clear silicone rubber sheaths to insulate them. See photo below. I've not seen any black insulating sheaths, but you could probably paint them if that's your preference.

You can find these connectors on ebay or from auto electrical suppliers. If you can't find any I could send you some.

The Voxbell horns on Laverdas present a particular problem though. Because of their flexible mountings, they tend to move around on the ends of their springy laminated stalks. This vibration causes loss of grip between the male and female parts of the connectors, either through wear, or the female spade connector bending open enough to come loose, so they need to be crimped tight again from time to time. A possible permanent solution is to solder wire tails onto the spade connectors on the horns and use bullet connectors a sufficient distance from the horns that they're not subject to vibration.

Spent yesterday trailing a group of frustrated racers on sports bikes across the WA countryside. I started off trying to keep up (well at least not delay them too much) but soon gave up on that. Even so it was a good workout. Nothing fell off (including me) and the suspension was better by a long way. The Lancelin road north of Yanchep normally rattles the fillings out of your head but it was relatively civilised. The front is still not where I want it but it's close.

Everything's​ relative. Thanks to support on the forum I've learnt how to do, and done, many things that would.have been unthinkable for me to attempt even a few months ago. For which I'm very grateful.

 I guess that some of these seem trivial to someone who has been maintaining these bikes (and others) for years but it's a steep learning curve for someone with no mechanical or electrical knowledge. I was pleased as punch to be able to eventually tackle many of the issues that have cropped up.

If it seems like I post a lot of issues maybe it's because I've done about 6,000km +  on a bike that hadn't turned a wheel in a decade.

I've thankfully acknowledged your advice, not sure what else I can do?

Hi Carlo, I made a completely new wiring harness for my Motodd using a really simple diagram. From day one it has been perfectly reliable. I was also a complete electrical nunce before I started and now I have trouble understanding why they made it so complicated in the first place.
I can send you a copy of the diagram I used, have a look at it. You'll need about 20 different colour wires, 5 relays, a bunch of spade connectors and insulators, couple of different size sheathing and heat shrink. Also buy a decent pair of crimping pliers.  I also used the Euro type of cable with thin wall insulation which reduces the bulk size. Once you've done it you'll know the wiring like the back of your hand. It won't be original so the rivet counters may have a problem.
Let me know if your interested.
As for posting, well if everybody spent more time doing it instead of asking question there wouldn't be fuck all to read on the forum so keep asking questions. I bet not many forum contributors have put as many miles on their Laverdas as you have been doing of late and posting some great photos. If you find you way in my neck of the woods [Walpole] drop by so you can see what I've done and I'll go through it with you.

All I was saying was if you have a wiring diagram then you have the key to the mess of spaghetti inside the headlamp shell.
First time I opened up the headlamp shell on a CDI loom 3C it looked impossible but as soon as I got a diagram it was straightforward to work everything out.
And I was a 21 year old eedjit.

Would be great to catch up Rob. I also remember your helpful post on the wiring previously when I had the no spark issue.

I know the electricial harness is my Achilles heel and I will get it redone eventually but that means quite a while off the road  and while I'm flat tack at work most of the time I want to be able to ride whenever I have a spare moment as it keeps me sane.

I have been using the diagram that Cam redrew and I'm pretty confident as to where everything is, and things like this indicator is likely within my capabilities to sort out, so I am listening to everyone , well maybe not SF ;)  just need time.

I actually couldn't believe the mileage when I looked at the dial!! It's still in Miles. Time for some new tires soon ;)

Always glad to banter, often makes me laugh loudly.

Writing today off as a 'tuning' day. Lots of short rides to test suspension adjustments.

Did a better job of setting the air gap in the forks, which was a bit wonky, and took two spacers (washers) out of each fork. Sag in the ballpark of 40mm.

Reset compression and rebound and reached an acceptable compromise after a few goes. Need to ride the bike when rested, and ride it harder. Feels like it might need a lite bit more rebound. Watched few Dave Moss suspension videos today, although he generally works on more modern bikes the principles are the same.

Seem to have lost the rubber boot on the brake lever which was why the lever was feeling funny, adjusted so back to normal but will have to find another boot from somewhere.

Sunday breakfast crew on West Coast highway must think I've lost it! Up and down the same stretch of road all morning. The suspension adjustment tool tucked away under the seat and spanner in the ducktail toolkit I had a red hot crack at fixing this harsh suspension.

Started with more preload to get the sag down to 35. I think this was the missing link previously, I had it closer to 40. Now with the spring in a better working range the compression and rebound have a meaningful impact on the ride. So after about 20 mini-rides I think it's somewhere I feel comfortable leaving it for a while to properly test.

In hindsight, I should have started with rebound and then tweaked compression but was sure that the harshness was as much to do with the valves over damping the compression. Its hard to know what the bike should really feel like but the stretch of road I chose is particularly bumpy with a series of well-placed manhole covers to test once I was a little braver. It now handles them as well as any sports bike I've ridden up there.

It's amazing the difference that the correct rebound makes to the feeling of the bike. Really think its a worthwhile mod if you get around to it. I take back my previous indifference to the Sportsvalve kit. If the suspension basics are set up incorrectly or its installed incorrectly then the Sportsvalve isn't going to work properly.

It's really impressive to feel or in reality, the lack of feel when you have great suspension. I had my Husky done years back by a pro, before in deep sand whoops it was a real struggle to push it. Necessary in deep sand, afterwards I could just pin it and hold on. It just worked.
Feels great to make a change that has an effect.

Well I'm out of my depth now on the two suspension threads that are in full swing so posting back here for the record.

I am indeed one of those blokes that's fitted valves and is now chasing a good setup from a fairly harsh set of forks.

I've tried the bike with different levels of preload and have at least some insight. The valves themselves actual add the equivalent of a 20mm spacer so, and I've also tried with an extra 1.5 (1 washer), 4.5, 6.0 and 12mm. The forks were least harah with 1.5 but bouncy as hell. However the rebound and compression couldn't be set properly at the time because I was waiting for the adjustment tool.

Having received the tool I and after fitting the fork caps I proceeded to ignore the damping control and immediately added preload when actually it was probably rebound damping I needed most to cure the pogo stick.

So I've just gone back to 1.5mm of additional preload and added some.Rebound damping whilst leaving the compression somewhere in the middle of its range.

Will be travelling with the adjustment tool u see my seat for a while.to try and get this sorted.

Clutch cable snapped today whilst lane splitting at slow speed. Gah!

Luckily I had a spare (after my eldest son dropped it down to me). Limited tool kit covered the neccesary for the change and was back on the road soon thereafter.

Also blew the fuse for the lights today, no idea why.

Found a replacement headlamp bracket today to replace the very average Mostyn ones. They are Tomasellli. The only difference apart from the finish seems to be a much firmer rubber mount rather than the foam of the other. Hopefully they will bolt up more securely.

Bored of front suspension shenanigans. Was so bored I put my old non-progressive springs back in for a comparison - don't even know what weight they are. Will make the ride to work more interesting.

Taking it to a long time suspension specialist for third time lucky professional opinion week on Monday. He can pull the buggers apart completely and see whats up. My money on something worn out in there somewhere.

The old (non-progressive) fork springs worked better than the progressives. Again the missing link here that while I had the old springs in the Sportsvalves were not working at all, so now I can play I might be able to find a setting but I think  a new set of non-progressive springs that are more my weight are in order. I have no idea what weight the old springs are as they have no markings anywhere.

According to the green book index, std was 1.2 and I have either .9 or .95 eibock, one of those is the heaviest they make that fits and I am 130kg, or a bit more. I hear most suspension blokes recommend the ones I have for 100kg approx. Give Terry Hays a ring in Sydney

I've used 0.85 N/mm Racetech springs on the last three bikes I've done, including my own, and think they are a good starting point for an 80-90kg rider.

If you want the rate of your old springs, measure outer diameter, wire diameter and total number of turns (tip to tip) and I'll plug them into a calculator for you (or you can likely find one online). Not to be taken as gospel but gives an idea.  I did it for my old Bimota springs and came out with 0.96 or so, bike ended up needing 0.85's for a decent front end so that all tallied ok.

These could conceivably be 1.2 as they are pretty heavy, as am I. I' 110kg with no gear so some 25% heavier than the average. The progressives were 9.25 and I think that what I've been struggling against is a spring that is too light for my weight, so that the only way I get it in the zone for sag is lots of preload, which then makes the ride harsh as well. Will be good to experiment anyway.

Pleasant if bumpy ride to York today. The festival itself was the usual dirge of dealers and small time vendors but weather held for the ride back.

Suspension learning continues. I re-read the manual on the valves today and discovered there is only 6 full turns of compression. I realised that at some point I had adjusted from fully out rather than fully in (closed) but fully out was something like 11 full turns, which meant I was probably well outside adjustment range, and even when I thought I was adding compression I wasn't as the valve was still.fully open.The ride to York was a bit hairy! (Note to self you are supposed to always adjust from fully closed for damping, but fully off for Preload)

Not surprisiny once I had the compression back in its adjustment it felt much better!

Luckily I have a sealed aircraft type cap and breather, it's hard to find a good spot for helmets to stop on. Its too easy to have them fall off the seat, hanging on the mirror dings the liner and putting them on the ground lets spiders, Bull Ants etc crawl inside. They seem to like the sweat. It was interesting watching one of the Victorians on the Snowy Run try and kill a spider that was in the process of multiple bits while he was riding after leaving his jacket on a log type seat during a rest stop. We have plenty of bittys down here.

Good tip Piet. That had never occurred to me. Not that I put my helmet on the tank very often, but I have done it on occasion.

Having had helmets fall off parked bikes more times than I can remember, now I just put it on the ground to start with. Stuff can't fall off the ground. In places where there might be nasty creepy crawlies or the ground is wet, muddy, or otherwise unsuitable, I'll sometimes hang it on the mirror.

I do remember one time when I put my helmet on the ground. I placed it upside down to avoid getting any nasties in it, but a dog came along and pissed in it. Fortunately it was an open face helmet so I didn't have to suck in dog piss aroma on the way home. I just got a wet head. The hazards of motorcycling eh?

Bull ants in my helmet, something I'm not keen to repeat. There's basically no safe place on the ground for a helmet in Oz.

Helmet manufacturers don't want us to hang of mirrors, straps, put in tank etc etc. We all have to ride around with a fecking velvet lined top or ride a scooter so we can keep the helmet under the seat (and our vaginas out of the wind).

Lovely brisk morning for a ride.

I'm going to try and take mine to a 2 day Champions Ride days at the end of May and ride Group 1 with the Laverda and Group 4 with the Aprilia.

Third time lucky: bike in to Russell Speak at Dynotime today with a view to finally getting somebody experienced specifically in suspension to have a look at the setup. At the very least we'll get some new springs.

Russel was also sceptical about progressive springs so thats good to hear. He felt that progressives would just make the ride harsh.

If I'd have known I would have tried to pinch it ;)

Feel like a while since I posted. Bikes been away and I've been busy.

New springs are in.

Turns out the old ones weren't hard, they were way too soft, they were a 7!. The way the sports valve was mounted on the damper rod it was blocking the flow of oil which in turn was making the ride hard. So Russell made a collar to provide some spacing between the valve top and damper rod.

He also noted when adjusting the valves that to get the same feeling from both he actually used different settings on each leg. So he used different settings between left and right fork. He's old school and does this all by feel.

I didn't even ask him what he put in, was too knackered from a hard few days at work. I actually think thats because if the compression isn't set from fully closed it can cause the rebound clicks available to be limited. So will make a note of his settings and try and even it out. So many questions I forgot to ask him,

Bike felt pretty good, lot less harsh but was riding higher at the front which made seemed to make the bike run wide. Will need to give it a proper ride at the weekend to find out but feel like I want to drop the front a tiny bit (3mm) to give me back the handling I want. I could try putting the longer rear shock eyes back on rear but frankly can't be bothered.

Instead of tinkering with the bike I started tinkering with a new gadget - a Raspberry Pi
(http://au.element14.com/wcsstore/ExtendedSitesCatalogAssetStore/cms/asset/images/common/raspberry-pi-landing-page/rasp-pi-3-board.png)

I'm thinking about making something that works for the bike out of this little computer just no idea what!!! It has built in Wifi and Bluetooth and can be rigged up to a whole heap of sensors and peripherals. No idea what but with a small touchscreen I reckons theres some potential. Not really...too hard and irrelevant.

Pretty cool little gismo for hobbyists got cameras, sensors (including gyroscope and accelerometer) and even an LED panel

Take care, it's easy to end up with the handling you want but a seat height that's hard to live with like mine. Data logger kit, how useful I have no idea unless your racing and can use it combined with lap times to prove an effect is good or bad. How you could use that on the road I have no idea. Having a different setting for each fork leg would rankle me, it would be like having a different carby setting for individual cylinders. Definitely an engineering possibility as having both them exactly same but in all regards, it would still rankle.

Post by: cbertozz on May 12, 2017, 00:03
These sportsvalves are tricky things. I've noticed that if the compression adjustment isnt in its normal operating range (6 full turns) it impacts how much rebound adjustment there is. However if you don't know it's only six turns (and I didn't give Russell the manual) then it actually turns out way more than that. (Given there are 30 clicks of rebound the compression not being a clicker is a bit confusing as it doesn't hit the stops until way out of its range when winding out from closed).

So perhaps he fell foul of that, although it sounds odd given his experience.

I'll see if the compression damping component is in its operating range. I'll make a note of his settings from closed and then compare.

In terms of seat height I'll probably go with adjusting the front first. With the stiffer springs and the collar it's sitting up more - so lifting the forks up through the clamps should do the trick?
Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: cbertozz on May 14, 2017, 15:21
As suspected the compression adjusters were way outside of their range.which was most likely why he couldn't get them the same with the same settings. Put them back to normal and adjusted accordingly. At least he made the collar so the oil can flow.

3am here, can't sleep and I've just answered a PM from another forum member about the Raspberry Pi I mentioned above, which was probably the last thing I expected to do on here! Glad to be able to help somehow, given my limited knowledge of Laverdas.

It got me thinking about an interface between the R-Pi and the bike and the obvious thing would be the Ignitech box. You could use a RS232 serial to USB interface adapter for the device.

They've recently release an even smaller R-Pi so the actual unit could sit up on the handlebars no problem and not be obtrusive.
(https://i.kinja-img.com/gawker-media/image/upload/t_original/wvd1awwp92wklcmctk6h.jpg)

And there is which can function with a simple LCD screen
(http://www.raspberrypi-spy.co.uk/wp-content/uploads/2015/04/lcd_i2c_screen_01.jpg)

So now I'm thinking maybe it would be cool to be able to see what the box is reading while you are on the go and to have that display on a small screen. I know its completely off the reservation in terms of having this sort of thing on the bike but might be interested if only as a diagnostic. Something for the long winter evenings.

If you get one make sure it has an illuminated screen for night work, some don't. Some even have a tacho, more usually dirtbike ones. Don't leave the maximum speed achieved up on the display if you get pulled over.

Sorry, haven't mastered pics. The things are only about the size of a matchbox and are very easy to fit, designed to fit to handle bars funnily enough, the microswitch and magnet can be a bit of a challenge to fit though. The modern ones run by wifi from the GPS off your phone but I've got the old school stuff. If calibrated correctly they are far more accurate than the bike's speedo.
As Vince says, make sure you reset the highest speed function if pulled over by the boys in blue.

I bought one of those little bicycle speedo gadgets for my track bike. I fitted the bike with rudimentary lights and indicators so it could be registered for road use, and a speedo is also a requirement for registration.

It was a wireless one that used some kind of transmitter to send the signal from the wheel sensor to the display unit. But I couldn't get it to work. I thought it must have been faulty (cheap Chinese crap from ebay) so I bought another one. Still wouldn't work. In the end I discovered that the distance from wheel sensor to the display was too great. On a bicycle, the magnet fixes to a spoke and the sensor can be placed half-way up the forks. But on my bike the magnet was near the hub (attached to one of the disk carrier bolts) and the sensor at the bottom of the fork leg. That extra foot or so of separation was enough to dissipate the wireless signal.

Next time I'll try one with a wired connection to the sensor. But there's no pressing need any more because the bike got through its roadworthy test and is now registered.

I mounted a magnet (not the one that came with the computer) in a hole milled into one of the rear disc bolts. The sensor is mounted on the rear caliper carrier, that way the magnet and sensor stay aligned regardless of final drive chain adjustment. Has worked well over the last ten years or so but had to buy a new computer as the old one finally fell apart. The new one even has a temperature sensor (thermometer in old-speak), who would have thought? ;)

Two days of riding the Laverda before going to Collie to race in the Moderns class with the Aprilia on 11th June.

Suspension still not as I want it but getting close.

Headed down to ride the Aprilia for two days last weekend for the first time since October last year.

Yes Bear will have to start again at some point, chuck out these sportsvalves and put in some gold valves.

It really did.

Need a quick action throttle, was awkward having to wind on the throttle with a second fistful and made rolling off hard when coming in at speed. Would definitely allow you to exploit the power better.

Would be good to get some more modern brembos, although the brakes didn't let me down it was always in the back of my mind. The bike was really good under hard front braking.

Apart from a little bit of chatter on the edge of the tyre through one particular bumpy corner the suspension acquitted itself well. I felt the back move a few times under hard acceleration in 2nd gear but the track was greasy.

The track at collie is so small that even the Jota didn't get  deep into the red zone as the straights are too short, and I also didn't want to flog it. Shorter gearing would help a lot if racing there but no point in changing as it's still a road bike.

I'm assuming there's also a lot that a mob like Redax could do to lighten the engine components and have the engine spin up faster. Some rearsets would also be good.

I am tempted to enter the Historics next year, it would be great fun on this very capable machine. I can totally see why they did well in the late seventies.

The year puts it in the same class as Tony Hynes GSX1100 etc...no bloody hope, I spent a lap behind him on the RSV4 and it was flying.

Few more pics. Overall I finished the day having done all 7 sessions, which I would struggle to do on the Aprilia as its so much more demanding to punt around even though its lighter and more nimble, the 200hp means everything is happening much faster and harder. That fact alone makes me wonder whether even if it's not with the Laverda whether getting into historics might not be a bad thing. Just need to find a class where the bikes have enough power to push my deadweight along and not rip my arms out of their sockets.

Have been rather neglecting to keep these ramblings up to date, probably because the bikes been running well to date!

Switched to Bridgestones and have found them to be much better than Metzlers so far. Even from new the Metzlers felt a bit funny and flattened off super quick, probably because they were a sport tyre. Wanted a new set for the track day and wasn't dissapointed even on a pretty greasy track. (so greasy you can see the reflection of the bike in the surface on a couple of the pics).

Loving the clip ons, hadnt touched them for weeks until the track. May just leave them where they are now to see how they are on the road, a little wider and a tad lower.

I've resigned myself to the suspension as 'thats just how it is" and considering how well it performed at the track I think I can cut it some slack. Seriously on a circuit that's bumpy as fuck it the front and rear were great. The sound of the bike at the track was amazing apparently, standout compared to all the moderns running around.

Can't think of anything other than the fact that it needs a good clean and probably needs some sort of service.

have a sit on someone's triple in Perth with rear sets and check them out if they feel better
plenty of triples in Perth, Mike has a set on his 3CL and you have meet up with him a couple of times

meet Mike for a beer at Little Creatures, walk around the corner to his place and try the position
just a thought

Had the rear pads replaced last week when new rubber fitted. Since then the rear brake has been stubbornly refusing to be bled. Seen the various posts about taking the caliper off so will try that.

Had the rear pads replaced last week when new rubber fitted. Since then the rear brake has been stubbornly refusing to be bled. Seen the various posts about taking the caliper off so will try that.

From memory the rear looked like it would be difficult to remove because one of the bolts is obscured by the frame. Anyway will figure it out.

If the M/C has been actuated with the caliper off the disc, chances are the M/C seals are knackered.  Not uncommon to have them refuse to regain pressure once the seals have been moved over their "normal" range of movement.  Either there is a ridge in the M/C bore, or accumulated crud that ruins the seals.  New seal kit required, everything else has proved to be a waste of time and effort... ;D

I should clarify...

It seems to be fixed when bled, and immediately after, but then you go for the brakes another time later and it needs pumping to get the pressure.

That's different to the situation you mention above - where it's impossible to get pressure?

Is the fluid level dropping in the reservoir?

As far as I can tell the fluid lelev isn't dropping, no fluid going anywhere. Hose doesn't appear to be leaking either.

It was fine until I had those pads changed.

Post by: sfcpiet on July 02, 2017, 14:17
Check the disc for warpage, pushes the pads back to the point that lever travel increases till you regain pressure.  Or the anti-rattle (there they are again ;D) spring and pin are in good order, and that the pad locating pins are a tight fit in the caliper.  Wobbly pads will also eventually knock back the caliper pistons.  Does the lever have clearance to the M/C piston?

Carlo - to get the cleverly designed SOB bolt you need to undo the torque arm and axle and slide everything to the front - there is just enough room to get a key on the bolt with a relief area in the frame - my rear disc was moaning on light application so i got the caliper off pumped until they were together - cleaned the pistons that had been exposed - then split with a screwdriver - reassembled and all is good - pads were fine - one thing that i was advised is clamp the disc with the rear brake while tightening the torque arm bolt - tricky solo but possible  - good luck

Post by: Dellortoman on July 03, 2017, 03:09
There's a tiny little hole in the MC that allows fluid to flow from the reservoir into the hydraulic system. The hole is exposed when the MC piston is fully retracted, so it also relieves pressure from the hydraulics when you release the lever. The hole being so small, it's easily blocked with a bit of crud. It's impossible to bleed the system if it's blocked. Blockage often occurs when you put new fluid in and try to bleed it through. Probably because it stirs up the sediment in the reservoir and it gets sucked into the hole.

That's exactly what happened to the rear brake on my Pantah, fitted new pads and then spent 2 full days and every trick I knew trying to bleed it. Gave up and took it to xxx shop. A stupid amount of money later I picked the bike up with a working back brake and attempted to ride home.Halfway there the brake stopped working so I stopped and found the calliper hanging from the brake hose and dangling down onto the road. Luckily it hadn't dropped into the wheel and had me crash. The fuckwit mechanic had done the difficult bleed but had not tightened the calliper bolts afterward. Made an interesting phone call when I finally got home not dead.

Rear brake seems to be working again so maybe that last bleed and some more riding did the trick.

Bought some old Honda switchgear yesterday that is nicely aged and narrow enough to accommodate the QAT.

Running continues to improve as I'm into the second full tank of 91, although will run 98 at track only as the issues seem to be only at road speeds.

The story doing the rounds and hear by me from someone who knows his stuff is the 98 has a bit of the vegi matter to it, and the 92 is fine. That's the exact opposite of what I have been doing for years, highest octane I can get to stop any pinging in High compression engines. Be a good thread on here.

When I had my Jota on the dyno a few years ago, the dyno bloke asked me what fuel I was using. I told him 98. He suggested we take the tank off and do a dyno run using his portable workshop tank with 91 in it. There was no difference in the power curve and no pinging on either fuel. I'm not too fussed now if I'm out beyond the black stump and 91 is all they have.

When I bought the bike, the PO said it wouldn't run properly on low octane fuel. He put 98 in it and then added octane booster! But the problems were due to it's god-awful state of tune rather than the fuel. Everything was wrong with it - ignition timing, valve timing and carby setup. It was only making 50 RWHP and burning twice as much fuel as it should. Now that the tuning is sorted, it's running way more efficiently and is happy to burn pretty much anything I put in it.

Once in a while if you own enough bikes, and like to modify them to suit, then you will come across a mod that is a game changer. The quick action throttle is a game changer IMHO. The fact that quite a lot of you came out of the woodwork with yours suggests its well known, but it had passed me by.

Allowing for the fact I've used whatever switchgear I could find quickly (will look for some better now I have it done), the effect of this is all positive.  Clearly its quicker to wind her up, which will make the track day much easier on Saturday but it also makes blipping the throttle better, which makes gear changes better. I find the small modulations are good and better suited to the engine characteristics and it doessn't feel like it will be tiring in any way - no problem with heaviness and kept the original springs.

Couldn't tell you anything about the QAT as everytime I opened up the throttle the rear would start fishtailing.

Onwards and upwards!

Overtightened the 10mm dome head nut holding the exhaust on....hoping that's just a Bunnings job.

You won't get one at Bunnings. I's a M6 stud embedded in a rubber mounting block. Not only that, it's a double stud block with 2 studs each side - not a common thing. Try Red or Wolfgang.

So I have to replace the whole thing? I thought I could just remove the bolt from the block and replace. Anyway if Greg has them that's fine.

The bolts on the double mount rubber exhaust mount blocks (at least on the one that I recently tore apart) have a big flat square head which is embedded inside the rubber during the manufacturing process. It's not possible to replace the broken bolt without destroying the rubber block.

The single bolt rubber mounts (like those that hold the oil cooler mounting bracket) have the bolt fixed to a round flange the same diameter as the rubber block, which is bonded to the rubber. It must be a bloody good bonding system because when they fail, it's usually the rubber that tears, not the glue coming unstuck.

The round blocks are available from various machinery and rubber suppliers. Here's an example https://www.essentracomponents.com.au/index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=12121&gclid=CjwKCAjw47bLBRBkEiwABh-PkVCaaDl1iW2Af-1VmrRiHEjgqdYwjvW86d-F7w5qiQzu58-4u8FaAhoC5MIQAvD_BwE (https://www.essentracomponents.com.au/index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=12121&gclid=CjwKCAjw47bLBRBkEiwABh-PkVCaaDl1iW2Af-1VmrRiHEjgqdYwjvW86d-F7w5qiQzu58-4u8FaAhoC5MIQAvD_BwE)

Having said all that. I don't think it's necessary to rubber mount the exhaust on 180 deg Laverdas (that don't have a rubber mounted engine). Most other breeds of bikes have solidly mounted exhausts. The rubber blocks on my brother's 3C disintegrated last century and it went for many years with wooden block replacements and straight through bolts. Nothing cracked from vibration. Makes me wonder whether the cracking common to the 3-2 collector is actually because of the rubber mounts, which allow the mufflers to bounce around independently of the headers.

Back in the days when my mates and I used to ride smelly old 2-strokes, we'd chuck our exhaust baffles in the fire to clean them. It got rid of all traces of oil and carbon. If you were going to get a system chromed anyway, you could probably clean it out the same way. I reckon all the welds would be stress relieved by the time it's done too.

Having had two sets of Smelly two stroke exhausts  :D rechromed over the past few years here in the UK,a lot of plating companies won't touch them but others will as long as they carry out the cleaning process themselves........involves generally stripping and leaving them in the pickling bath for a couple or few weeks to get rid of all the oil contaminants......both sets came out extremely well.

Four stroke systems i have always thought would not be so much of a problem especially with a clean burning Laverda  :D however I am sure it would have to undergo the same cleaning process  (thumbup)

Get a bit of the carbon in the silencers glowing with an acetylene torch, add oxygen... rest cleans itself.  But be sure the neighbour doesn't have any washing hanging on the line. ;D  Results in interesting hues of blue in the chrome, too. ;D

After a day stuck to the laptop and evening cruise was in order. The trouble with Perth is there's nowhere to cruise to on the coast apart from the Marina! Ride felt good in straight line, but bike seemed to be tipping in a little over-eagerley, turned out to be 25psi front tyre pressure.

The little moonfaced dude on the wall seems pleased to see the Jota; I swear that I didn't see it when I took the photo, never noticed it anyway.

Post by: cbertozz on July 23, 2017, 14:26
So as mentioned above I found my front t tyre pressure to be on the low side at 25psi.

In the morning when I headed out the bike felt great, and tipped in really nicely, and the front suspension seemed to be working well. (I have Bridgestones)

When I headed out again later in the day I felt like the nice tip-in had started to feel like the front end was folding from under me. It was cooler so perhaps it had lowered pressures to a threshold the bike couldnt cope with.

I put the front to 36 and the rear to 38 and headed out again. The ride was harsh and bumpy and this makes it hard to commit in corners.

Took it down to 33 at the front and 35 on rear and it was better, less harshness, bumps etc and no folding feeling.

When I looked at some of the OEM pressures it looks like the front was around 30-32psi and the rear 32-34. So will take it to 32F and 34R to see how she feels.

Made me realise part of what I've been chasing for a while has probably been tyre pressures.

Other random thoughts from today; could I put my race bike back on the road for a bit; excited feelings about getting my knee down on roundabouts quickly reality checked by myself recalling my demerit points tally.

Post by: cbertozz on July 23, 2017, 22:45
Thats where I've been running it up until now pretty much. (actually 36 /38)

Clearly I need to go back to adjusting suspension. Trying to track down an article which tells me whether its compression of rebound that the high pressure is emulating. My understanding was that the rebound from the tyre itself is at too high a frequency to interfere with the suspension so its essentially the 'hardness' that is emulating too much compression - so if I dial out a little compression it should get it back to where I need it. Anyway, will have to keep searching for that reference.

Pretty interesting topic, tyre pressures and suspension settings. Could be bold enough to say that the topic is more relevant to the average Laverda punter than the debates concerning the 'correctness' or number of rivets that are present on some models.

The reason why there is lots of Emulator fiddling is that when they first appeared 10 years ago Race tech sent them out with vastly different settings to what you get when you buy them now. I expect the past 10 years has resulted in some better experience and consequently setting that work better out of the box when you now buy them.

I've got a car tyre on the back of my Kawasaki 1300.
OK, it also has a square profile front tyre and a Mini wheel on the sidecar.

For the back wheel, I bought the cheapest crappiest, hardest, slipperiest car tyre I could find. It's preferable to not have too much grip at the back end with a sidecar outfit. Sometimes it's handy to break traction at the rear to turn the bike quicker. It's also a lot of fun.

Apart from the intermittent back brake, slight asthma at 3250rpm and  growing sense of uneasiness about how long since the bike was properly serviced, all is well.

It's fucking cold here at the moment which doesn't add to the riding pleasure.

Ok will go get a feeler gauge tomorrow, I have to admit I'm actually curious to do this. Will have to read up about it though. I read something else that mentioned at least one other tool I don't have.

Hey Chris. You needn't have worried. There are no recorded incidents where a human was carried off by a wedge tailed eagle. They're smart enough to avoid confrontations that could cause them harm.

There are (unsubstantiated) claims that wedgies have been seen in the wilds of SW Tassie with wingspans of up to 310 cm. But I dunno how anyone would reliably assess their size while they are on the wing. Like you say, it all depends how close they get. The claims of large sized birds probably came from some scared bloke with a small stick  :D

Very kind of you  Sir Sydney!

So one of the reasons I've been a bit slow to fix some of the outstanding issues with the bike, and do a major service, is because I can't bear to not be riding for any length of time

Fortunately I have a good friend who is going to mend me his KTM 1299 Superduke for the duration.

So it's:

Clock restoration
New paint job
Major service
Complete detailing
Seat repair

The hardest thing willl be deciding on the colour.  Thinking about putting it back to Black but do like Green.

A common failure point when it's solidly bolted to the fork leg as yours appears to be. There should be rubber grommets in the mounting holes, with little steel spacer tubes in them so the rubber doesn't crush when you tighten up the bolts.

Not sure when the transition took place, but early versions of the bracket only had provision for 8mm bolts and were mounted solidly to the fork legs. 

The solid-mounted bracket should slide into the fork/wheel assembly snugly, and not exert any pressure on the sliders when bolted up.  Checking slider movement without the fork springs once the bracket/guard are fitted isn't the worst idea one could have...

Post by: cbertozz on August 20, 2017, 01:50
Thanks for the feedback guys.

So it seems entirely possible that they were hard mounted originally, but probably worth using some sort of grommet in future.

The issue may be that I reversed the mudguard to get that cleaner front edge - that somehow after best part of 40 years they had changed orientation slightly and that was now working against it.

Could be something to do with suspension, the  suspension specialist that looked at it last time said he felt that the forks were working differently on the same settings so had set them up differently. (Which I changed later becuase it didn't feel right). After the break the suspension doesn't feel any different so I doubt it was this.

So I assume they can be repaired? Thoughts on that?

Post by: Vince on August 20, 2017, 02:31
Sure, bit of welding.Don't know if they're stainless or chrome though.If you go grommets check as you tighten it that the guard is centred over the wheel, there will be enough wiggle to misalign the guard a bit. BTW once on with Alan bolts, you cannot access it while the wheel is on to adjust this.
Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: Dellortoman on August 20, 2017, 02:35
Check the size of the bolt holes in the mudguard bracket. I forget the exact size but if they're substantially bigger than the M6 bolts (about 10mm) then they're sized for grommets.

My Jota came with the mudguard bracket solidly bolted-up like yours. It had 10mm (approx) holes in the brackets so I figured the PO had simply left out the rubbers, but after Piet's comment, who knows? Anyway, it broke just like yours. It was easy enough to weld up again, but I wasn't confident that it wouldn't break again so rather than re-chrome it after welding it back together, I painted it to simplify future repairs. It's easy to spot my bike in a crowd of Jotas. It's the one with the black front mudguard bracket - see photo below (I don't normally ride in a double-breasted suit. It was taken on a Distinguished Gentleman's ride). Anyway, I may as well have re-chromed it because it's never broken again since I rubber mounted it.

Being the cheapskate I am, I didn't buy the parts from a Laverda parts supplier to rubber-mount it, I just bought a bunch of suitable size cable grommets from an electrical supplier and made up little stainless steel spacers on the lathe. If you can't get them from Wolfgang or Andy Wagner, let me know and I'll make you up a set.

Cheers,
Cam

Warm enough there Cam. One thing that I had a struggle with was the grommet inner stainless steel sleeve length, it needs to be long enough to not take out the flex from the grommet or too short and crush too much.Not easy to cut without a lath either.Finding the right outer size washer also needs to happen. Took me a couple of goes to get this right.

Nice and sunny here today Vince. It's a sweltering 11į C.

I think it took me a couple of attempts to find the optimum length for the spacer. And yes, the ends of the spacer tube need to be cut clean and square to the tube axis. Not saying it can't be done with a hacksaw and file, but a lathe is the quickest and most reliable way to do it.

Started to tinker with the carbies today. Removed the float bowls, as basically the easiest thing I could do without fucking up something (I have all the gaskets etc).

I still had the stutter at 3250 despite the change of plugs etc (yes I know I said it was gone but was kidding myself or it was temporary). Draining the float bowls seemed to cure it.

Good run in the country today.

Some, a fuel / water mixture I think in at least one.

If there was water in the float bowls, there may be water in your fuel tank. Probably condensation. Have you had some humid weather recently?

Put half a cup of methylated spirit in the tank next time you fill up (tip it in before filling up so the incoming fuel mixes it up well). That should mop up any water.

Water won't mix with fuel, but it will mix with metho. The watery metho then mixes with the fuel, so it all becomes a homogeneous mixture and will pass through the engine. A little water/metho going through the engine won't hurt anything. Might even give you a performance boost as the water flashes to steam in the combustion chamber  ;)

Try to use that tankful ASAP. If you're going to leave the bike parked for more than a day or two with metho in it, it's probably advisable to drain the float bowls beforehand (metho may affect carby o-rings?). Just turn the fuel taps off a few hundred metres before you get home and let it run dry.

Well itís been a while but the bikes been working fine and the broken shoulder has rather got in the way recently.

The transition to hybrid race/road bike has begun.

The old carbon tank and panels have been painted, so at least I have an orange Laverda. The tank was a pig to get sorted as the fuel tap fittings were buggered so we had to make a modified in-line fuel tap. Also replaced breather valve.

The second hand rearsets also needed a lot of work, welding the crack and then making the linkages, which also mean sacrificing the old gear lever. Lesson learnt.

As I wanted to keep the headlight on for road riding weíve now got a blanking plate to replace the headlamp unit.

Courtesy of Red we have engine protection (with a slider even) and we repaired an old alternator cover for the other side.

Have kept the rear seat and just need to get a jump seat to replace it with.
Still needs lock wiring, some race rubber and pads.

Some pics here.

Set up a basic web folder today as Iíve been exasperated by Google, Dropbox etc etc when trying to embed photos in the forum.

The new orange colour still a bit odd but with everything back together it will look great.

Now I have to work out how to fix the fairings on and raise the bike a little - I have some longer rear shock mounts which should help.

Have found a donor race tail for a Jota which hope to swap for my sfc version.

You don't muck around, my only suggestion is to check the flow rate of that tap is the same as stock or better. Last thing you want is fuel starvation and it running lean at full wack. Maybe you could do a timed fill of a measured volume in a  beaker and compare it to a stock tap.Better to be safe than sorry with piston issues.

Yep good idea, and got to get rid of those cable ties before Piet sees them.

When fairings and tail are done then looking at mudguards next. Think Iíve found an old front guard but not sure what to do with the rear.

Assume will look something like this..

The issue with a short rearguard is just like for me swopping from my twin thickly padded twin style touring seat to the SFC style solo seat I have but you need to keep the rear lights or at least make them in your case still connectable for road use. That's if you want to still use the Duck Tail and seat for road riding. I would love to do the guard circumcision on mine and run the lights off the rear of the SFC seat. That looks really sexy, but that seat won't allow 700k days for road trips, I haven't found an easy quick way to do this without leaving the guard and lights where they are, seats easy and a quick change for me to do, the rest not so much.

No Laverda content, just a rant at my stupidity at further delaying my return to 2 wheels.

Visited the Physio yesterday to get an idea of what I should be doing to get my shoulder and arm moving again as the shoulder blade was healing nicely. Good session, Physio reckoned arm/shoulder has good mobility and gave me some exercises.

Went home happy and relaxed, and then after trying to fix a pool pump I managed to stumble while jumping up a 2ft garden wall/terrace and fell hard. For some reason I instinctively avoided sticking my arm out to take the impact, but instead managing to roll as I fell and my side and back of my arm took the brunt of the fall. Had I stuck my arm out I think I would probably have been better off but who knows.

Upshot is the shoulder blade seems to have survived but now my side/shoulder hurts more than the bloody broken shoulder blade did. Cursing my stupidity but not a great deal to be done as I think itís just bruised.

Booked first track days of 2018 for Feb 3rd and 4th so I have something to be fit for if I can stay upright!

Too late I know, but, should have left the instrument lights and their bungs in place and disconnected the cable from inside the headlight. The bungs are Unobtanium (copyright and patent owned by Oakley). As far as I am aware the closest thing to them is made by Honda.

Instrument globes are 12V 3.4W 8BA.  Please don't fit the more common 4W, they get too hot and can damage the rubber bulb holders and can melt the little coloured windows and dial face.

I actively try and avoid night rides, better safe with my eyesight, ok in good light. But on the Tassie trip, it happened after dinner at Cams in Hobart.We ended up doing the 20ks after 9pm. I knew the tacko light didnt work but it must have been at least 6 or 7 years since I had noticed it. Its been on the too fix list that long. I have heard that LEDs are very bright with telltales, Flippen useless in bright daylight for the telltales on the Pantah dash and the heated grip temp indicators, you cannot see if they're on or not, I wonder how that would be for Instrument backlights.

Ken,

Although I haven't tried them in ND/Laverda instruments, I was quite disappointed with LEDs in Smiths Chronometrics.  They might be brighter, but only straight ahead, the light doesn't spread enough to illuminate the dials at all.  I was supplied with LEDs that were supposed to spread the light, but that part sort of disappeared into nothingness...  LEDs in the ND warning lights might be quite OK as the bulbs are contained in a channel, nowhere for the light to go except straight ahead, but I doubt that they will be able to light up the dials properly.

Post by: mcnicol on December 31, 2017, 15:33
Piet, the trouble with LED bulbs is that you can never find the same ones twice. The Chinese factories crank out a batch and then retool to make a bunch of buggy whips the next day, and by the time there's a demand for bulbs again the available chips are different so the bulbs are different. The bulbs I put in my ND instruments a couple of years ago did a better job of illuminating the gauge faces than the incandescents ever did (I have to ride in the dark every day to get to work, although I don't really enjoy heavy commuter traffic in pitch darkness, but at least I can see my gauges). I put the same bulbs in my Honda UJM commuter, and they just work flawlessly, very similar ND gauges. And the neutral lights on all my bikes are visible in full Florida summer noon sunshine, which was never going to happen with an incandescent bulb.

our first two years racing with Paul on the standard frame/18" wheel combo triple we started with Avons but eventually changed to the Conti 18" race tyres
suited the heavy triple better, just as much grip and lasted a meeting longer

now we are on 17" rims tyre issues are over, we just run Pirelli slicks

fairing is off to the painters next week.

I reckon you'd be better off dry fitting the fairing before painting it. Jota bars are different to SFC bars, so the chances are you'll need to trim the edges of the fairing so the handlebars/levers don't foul. My SFC fairing took a bit of fiddling and trimming around the edges of the handlebar and fork leg recesses before I was happy with the position of everything, and I was using clip-ons similar to the SFC.

I used a jigsaw for the surgery, followed up with sandpaper to smooth the edges again. Use a fine tooth blade and put masking tape on the gel coat side before sawing. You might need more than one blade. The glass blunts them very quickly.

So as they had to cut my race suit off Iím not just getting the bike sorted, I have to find a replacement suit.

Having been rather inconvenienced by breaking bones, especially as it impacts my work, Iím going to get a suit with airbag system. Horrifically expensive but nothing compared to the cost of me being out of action for weeks. I worked out I spent virtually the equivalent of half a new suit on Uberís and taxis alone in the last 6 weeks.

The Alpinestars one is locally supported and seems to be the best option as it has two charges before it needs to be reset. (Which involves sending it away to Melbourne)

When I first heard of airbags I thought what a joke,I thought in terms of the Michelin Man. Then I saw a doco on TV about The Alpine Star system and was impressed when even when the pros do brake collar bones its a much less damaging brake.I tried one of those Leet neck gadgets off-road and hated it, they restricted my ability to turn my head and look for danger. I am in favour of anything that saves you in a crash re protective gear. Not so keen when they talk mandating stuff for the road.

That breather looks a bit like a compressor hose fitting. It's kinda clunky looking to me.

I have one of these in my track bike's tank http://www.rallynuts.com/motorsport-fuel-tank-vent-valves/mocal-in-tank-vent-valve-horizontal.html (http://www.rallynuts.com/motorsport-fuel-tank-vent-valves/mocal-in-tank-vent-valve-horizontal.html)
It was the fitting that Red sent me with the Boba carbon fibre tank. Dunno whether it came from Red or Boba. Anyway, it's nice low profile and the drain hose lays flat on the tank. I run the drain hose forward and down one of the frame down-tubes to the bottom of the frame in front of the engine. Not that I expect much fuel to come out of it, perhaps just an occasional drip. It has an internal valve to stop fuel surge slopping out, but I suppose it's possible that a drip will get past before the valve closes.

They work ok just as long as you are really careful fitting it and its made to the correct width. It's very easy to get it to bind the fork so slowly fit and tighten with plenty of bouncing as you do it.

That breather looks a bit like a compressor hose fitting. It's kinda clunky looking to me.

I have one of these in my track bike's tank http://www.rallynuts.com/motorsport-fuel-tank-vent-valves/mocal-in-tank-vent-valve-horizontal.html (http://www.rallynuts.com/motorsport-fuel-tank-vent-valves/mocal-in-tank-vent-valve-horizontal.html)


I had a chat with Boba early in the piece wondering whether he could recess the aero filler cap and use a unit with built in breather. Apparently the moulding would prove a little difficult. But he did tell me where he got the cap and breather from, both Newton. Looks very similar to the unit you have linked to. https://www.newton-equipment.com/tank-vent-valves-tank-mount-valves.html

The breather on my Guzzi has done the same. The breather on Bears triple (Boba's carbon) did the same. I think the problem is not so much the contact between the surfaces of the breather outside the tank or the nut inside but that the edges of the hole the threaded section passes through need a coating of epoxy to cover the bare carbon edges of the drilled hole. I am going to make sure this hole and the holes drilled for the aero cap and mounting bolts are all well coated with epoxy before I refill the tank. I may need to clean the 2 pack off them before coating as they got a pretty liberal spray when I painted it.

Mine is in a std steel tank and it's the same.I think I should have sanded under it to a feathered edge and sealed it with some kind of Loctite fuel resistant sealer. I did some research on different washer types that are used to seal petrol taps to tanks and that would be a magnitude more extreme. Seems some use Stat- O-seal and some use Dowty, the Stat-O-Seal type needs a plain type washer between it and its fixing. As its a pain to remove my breather I want this done once and sealed for life.The fibre washer I used originally failed or at least didnt stop the fuel creeping under the paint.

I run the drain hose forward and down one of the frame down-tubes to the bottom of the frame in front of the engine. Not that I expect much fuel to come out of it, perhaps just an occasional drip. It has an internal valve to stop fuel surge slopping out, but I suppose it's possible that a drip will get past before the valve closes.

I curved the breather hose down the front of the tank and taped it up under the tunnel so that the hose sits alongside the crankcase breather pipe tip. Means the hose comes off and on with the tank. I had thought of routing it down the way you did but the thought of a thin plastic tube containing fuel and or fuel vapour sitting in close proximity to a hot exhaust pipe convinced me otherwise, especially when I had trial fitted a shorter hose that looped down and up beside the headstock and I saw how much fuel ended up sitting in the bottom of the looped tube at the end of a ride.

People used to put that hose into a hole in the steering head nut, worked great for washing the grease out of the bottom bearings.

Have it going through the steering on the Le Mans, but the tube extends out the bottom of the steering head and the pipes are not underneath.

Post by: redax5 on January 14, 2018, 19:37
we run that same Newton breather on our race bike fuel tanks
you need to run the hose initially to a point above the level of the breather, try and include a loop into the hose and then run it downwards

main issue was they dribble fuel out, did not worry us too much on the track as riders should be too busy to look at shite like that but taking the two bikes to and from the track, they would piddle all over the floor of the race van and dead set, I don't mind getting high but after 3-4 days of breathing race fuel, enough is enough

so we did the loop deal as described above and that stopped their incontinence while resting in the race van, but

we also found our tanks would be pressured up after a race, crack the fuel filler cap and you get a "whoosh" of fuel, may only be 3-4 psi but it has caused us an issue as we are in the process of getting new fuel tanks made right now as both the original tanks are split
#86 tank split 4 times last year and has something like 4 kgs of Caswell tank liner in it now

so my take on the Newton tank breathers, fuck em, looking for an alternative brand

Post by: Vince on January 14, 2018, 21:38
Its annoying especial after you think you have done it correctly, I added a dirtbike one-way breather valve to the anti-tip breather and it still self-syphoned when I would brim the tank, fuel over the bottom of the breather end inside the tank. That's with the hose coming up and along the handlebar. In the end, I drilled and tapped a 140 Delordo main jet into the bodies of the aircraft tank cap and that finally broke the vacuum enough to stop the syphoning. The fuel still creeped out under the breather, maybe capillary action and blistered the tank paint. Why is this shit so hard?
I remember reading about how the Gowy blokes had issues with the DB1 Bimota not running hard at Bathurst, seems that was a tank breather being too small to cope with the fuel flow at full wack on a fast circuit.

Interesting comments. I've never had an issue with my breather dribbling fuel. The breather hose on my tank is black rubber. Perhaps I should replace it with clear hose so I can see if there's any fuel in it.

Post by: sfcpiet on January 15, 2018, 00:37
I've found breather exits placed about half-way along the tanks' length to be the least problematic.  The fuel load sloshes around quite a lot under braking and accelleration, a breather near the front will allow loads of fuel to pass, unless the tank has effective baffles.  Trick around that is to fill only the amount needed for a race, plus a small safety margin.  Road riders are stuffed, simple... ;D

Was pleasantly surprised to find the simple breather hole in the filler cap of the Special to work quite well at the speeds it ran at Eastern Creek, although I'm not all that sure it can cope for long streches of WOT (will find out at Paul Ricard, the Mistral Straight is even longer than at the Creek, and I'll have the correct gearing this time so I hopefully won't need to back off prematurely ;D).  Just a 1.5mm hole drilled through the cap, positioned rearwards when tightened up.  Thought about using one of the filler cap flange fixing screws drilled lengthwise as a breather, but the cap has the advantage of being positioned a bit higher up.

My carbon tank has the Newton breather, never had a problem with it yet The hose goes down through the top yoke nut out the bottom of the steering stem then back up finishing on the fairing mount where the mirror is attached. Always a small pool of fuel in the bottom of the hose at the lowest point exciting the steering stem. No issues with the paint either.

That's what I've been doing, for the simple reason of reducing weight. Why carry 20 litres of fuel for a 6-lap race? Perhaps that's why I've not had a problem with the breather pissing fuel.

So I went to see this bike as I was passing through Melbourne again.

For $18,000 I was expecting something in better condition than I found. Donít get me wrong I think the bikes great and it is in good condition overall but I think itís a bit steep for what Iíd need to spend on it.

Greg Parish did a bunch of work on the bike and reckons itís a good genuine runner but did warn me about some of itís foibles.

The exhaust is buggered. The right hand side muffler looks like itís got a piece of armour plate welded on and the pipes buckled where it goes into the collector. Greg had a go at separating the pipe from the collector but even with heat he couldnít do it. To the point where they fitted on of those Redax sump plates that moves the sump plug to avoid the need to remove for oil change. Theyíre badly painted as well.

Mostly the rest is cosmetic. The tank is stuck up on rubber under the on the frame so that the velocity stacks fit. It looks fugly but then it also indicates they couldnít get it to run well as original perhaps? The indicators are all fugly Jap units. The paint is pretty good.

Was surprised to see Jota bars on it, always though they were just for the 1000. The tank also is Jota shape, something I didnít really notice in the pics.

When you look at the bike from top/back the screen looks twisted which is probably just the way itís mounted but given the knackered exhaust itís been dropped who knows?

I know they are rare but unless youíre buying as an investment then it has to stack up. Bear sold a perfectly good Jota for $18k. Has one sold in AU recently for less/more? (Iíve seen a couple of UK auctions but the bike was pristine)

our sump plates do not move the sump plug as a 500 engine never had a sump plug in the first place
by making billet sump plates we can then provide a sump plug that the 500 engine never had
same as the 750 engines which never had a sump plug to start with, hence we machine billet sump plates for them as well

is this an ex Brisbane bike, recently purchased and shipped to Melbourne ?

Starter clutch springs needed replacing. Luckily Justin from Protwin spotted the new qat didn't leave enough throttle play as well.

The only mystery is the gear change seizing up gradually last time out. Hopefully we'll be able to figure it out.

Won't have time for new tyres so have to work with the Bridgestones, not expecting to break any lap records and its not like they are slicks. To be fair not expecting much of a race unless a few other slower bikes rock up!

Taking Aprilia down as well to finish the shakedown on that now the shifter is sorted.

Well the weekend didnít go exactly as planned.

The good stuff:

Bike felt very stable and also agile enough, brakes held up, although started to touch the rear a little into the hard braking chicane. Have to muscle it a bit but when I put the longer rear shock eyes in I suspect that will do the trick.

Quick action throttle was good but need to put in lighter springs (or clip them) but as I have lighter ones Iíll start there.

The not so good:

Engine Iím afraid struggled misfiring or most like fuel starvation caused by the huge amount of swarf that mysteriously appeared in the fuel lines! It didnít run right all weekend, slowing progress a lot.

The tank is a boba carbon but it has been obviously been leaking and the taps were botched in, so we started again. Nothing was done to it that could have put ally swarf in there though. The only other possibility was that I borrowed some fuel a couple of weeks ago and that fuel might have been contaminated but seems unlikely. I had the tank on and off the bike that weekend to get it running, changing plugs etc, and never noticed anything.

(http://www.carlobertozzi.com/pics/IMG_1975.JPG)

Anyway having removed a lot of this stuff after tuning day and then again on race day the bike just got worse and after the start of race 2 it just wouldnít run past 4K so had to pull off. Iím flummoxed but will need to pull everything off and flush it all and get the carbies etc serviced because something obviously got past the filter mesh (no inline filters).

For standard road tyres the BT-45s did surprisingly well and felt confident after they warmed up.

The Period 5 Class is a bit lonely with GSXís dominating the field (the winning bike runs round Pi in the 1.40ís. My only target is a Ducati but the engine just wasnít capable of keeping up.

So even with a misfiring engine I was only 1.5s off the Ducati but a whopping 9s off the winner so a long way to go but laps were completely consistent around mid 59s. When I think I was running 54s when I first rode the Aprilia at Collie that doesnít feel too bad, but mid 50ís is the target with a fully functioning engine and better tyres.

Have my eye on this tail as a swap with the SFC tail I bought off Red. Love the look, maybe 0.2s lap in that ;)

Metal swarf from a carbon fibre tank.
No fuel filters in the fuel taps?
Is the swarf magnetic?
Very odd.

Very odd. I had the tank off and on last time out and didnít notice anything. The tank hasnít been off the bike since. I did use a metal fuel can when someone gave me some fuel but thatís the only thing I can think of unless it was in a clump inside and itís been shaken loose.

Well the weekend didnít go exactly as planned.

The good stuff:

Bike felt very stable and also agile enough, brakes held up, although started to touch the rear a little into the hard braking chicane. Have to muscle it a bit but when I put the longer rear shock eyes in I suspect that will do the trick.

Quick action throttle was good but need to put in lighter springs (or clip them) but as I have lighter ones Iíll start there.

The not so good:

Engine Iím afraid struggled misfiring or most like fuel starvation caused by the huge amount of swarf that mysteriously appeared in the fuel lines! It didnít run right all weekend, slowing progress a lot.

The tank is a boba carbon but it has been obviously been leaking and the taps were botched in, so we started again. Nothing was done to it that could have put ally swarf in there though. The only other possibility was that I borrowed some fuel a couple of weeks ago and that fuel might have been contaminated but seems unlikely. I had the tank on and off the bike that weekend to get it running, changing plugs etc, and never noticed anything.

(http://www.carlobertozzi.com/pics/IMG_1975.JPG)

Anyway having removed a lot of this stuff after tuning day and then again on race day the bike just got worse and after the start of race 2 it just wouldnít run past 4K so had to pull off. Iím flummoxed but will need to pull everything off and flush it all and get the carbies etc serviced because something obviously got past the filter mesh (no inline filters).

I'm still buzzing from yesterday. Muscling a bike nearly as old as you around a track at speed is much more rewarding than on a modern bike.

Even getting off the line was easier, and made starts fun. When I started riding at the track with a modern bike I started 10sec off where I ended up so I have no illusions about the work I've got ahead, although 5secs would make me competitive.

There's 1.5sec a lap in the engine working properly alone, another 1s in the tyres, and the rest is just willpower!

Bring on Easter and the Collie TT!

Bike back and ready to go! Slightly wider rubber BT45 130/80 18 66V and the 110 front so will be interesting to see how they feel. Assume it will tip slightly more progressively but as theyíve had no road use they should feel good whilst offering a slightly larger contact patch.

Lighter springs in carbies but doesnít feel lighter so weíll see.

Tank flushed, carbies cleaned and faulty connection at coil fixed. So fingers crossed it runs properly now!

Bar ends plugged so the scrutineers should be happy, and the Suzuki grips back on instead of those foam covers on the ridiculously thin Magura ones.

Learning the hard way about tyre pressures on these BT45s, lowside on left-hand T7 today scuffed up a few bits nicely but quickly fixed over lunch and was back out for the afternoon. Now down to 28 front cold and 30 rear.

The left clip-on folded and was undamaged, and weirdly the grip came off the bars but was completely untouched. I wondered whether it had come off in my hand which had caused me to crash or whether as the bike went away from me I pulled it off??

Red's slider & plate did its Job well and that case was untouched. Fairing a little scuffed and carbon tank dinged a bit but very minor, and why race bodywork us fitted. Exhaust has a ding but totally serviceable.

Raceday tomorrow!

Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: Vince on March 31, 2018, 19:17
The best way to keep grips on is to use those dirtbike ones with grooves top and bottom for safety wire, takes skill to get the wire tight so they are rock solid even when wet but not cut the grip. There are how to's on Utube.

From clipon I presume. Iíve often wondered how the carbon body work fairs in a bingle.

Howís your body after the excursion?
Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: Dellortoman on April 01, 2018, 02:26
Carbon fibre won't dent. It'll either deform and spring back into shape or shatter into a million bits.

Boba makes his tanks from Carbon/Kevlar composite. The Kevlar stops the tank shattering. If it deforms enough to crack, the Kevlar will hold it together, but the crack might leak. If abrasion damage hasn't worn a hole through it, and there's no cracks, it'll be OK.

Carlo, you'd be way better off with race tyres on the track. The Avon AM series tyres are pretty good for classic bike racing. On my RGS based racer I use AM22 110/80 x 18 front and AM23 130/65 x 18 rear.

BT45s are OK tyres for road use, but have limited potential on the track. Those tyre pressures seem pretty low for BT45s anyway. I run mine way higher than that at around 34/38 (for street use).

Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: GregT on April 01, 2018, 02:55
Those pressures - 28/30 are about right for BT45's on a heavy bike on track. The carcase moves around more than some brands - so the tyres heat quite quickly - and the pressure rise is steep.
What you're using is pretty much what we used on a GS1000 racebike - and we were beating bikes on slicks...

Post by: Vince on April 01, 2018, 03:20
Those track pressures do my head in, had a long discussion elsewhere about this. My first and last at this point track excursion had me on Bridgestone BT92 rear and a BT023 front at my usual 37 42 road pressures. In the 5 laps I did I was close to absolutely destroying the rear, I admit I was spinning it up exiting the non-blind corners, really good fun with all going the same way and no cops in the bushes. I had zero track knowledge so blind bends were not fun.I was asking the track boys how they didnt do this damage and the answer was running almost sub 30psi. If I did that on the road the bike would weave about like crazy.BTW this was some parade laps with 28 other Laverdas, tried it the next year with 120 other bikes at the same time. NEVER again, scared me good with some absolute crazy lines being used into the very fast turn 1 at Eastern Creek.

Track tyre pressures have absolutely no relevance for road riding. What you say is spot on Vince.
MotoGP bikes have compulsory sensors so that the officials can ensure that they arenīt running dangerously low pressures.
I also agree with Cam. BT45 are an OK road tyre, and despite the old days of proddy racing in Oz with all sorts of tyres getting shredded around the tracks and putting out good laptimes, they are not designed as a race tyre, as are the unbelievably effective race AM Avons. This year Iīm switching to the Conti radials after a decade totally happy with Avon, after all the raving about the Contis. I sure hope they deliver the goods. 28/30 is what I have run with the Avons, 130 and 110 on 3" rear and WM3 front rims on my SF.
Bloody glad that your little off went so well Carlo. Great to have you flying the flag there.

Post by: cbertozz on April 01, 2018, 08:30
Well the pressures worked well up until I was taken out by the 125GP Mafia into T7. They put the 125GP in with P5 Unlimited and gave us a 20 sec head start.

I was fully tipped into T7 and almost on the apex a 125GP barrels into me and sits me up and this pushes me into another right alongside which catches my bars.

Crashed on right side this time to even things up but punched a hole clean through the tank, broke the alternator cover into a few pieces and wrecked the master cylinder.

It was a racing incident but canít help but feel a bit hard done by today as noone in our class would have done that. The marshals made a point of coming after me to tell me that they thought it was out of order and another competitor complained to clerk of course. I didnít think it was worth lodging a complaint as this stuff happens.

Anyway onwards....

The 125GP lap at Moderns pace (1000/600 Moderns) and its completely contrary to choosing to race Historics. I don't expect to be in a class with bikes that run the same pace as Club 1000, or rather that have such superior corner speed and handling characteristics.

Here in the South Island NZ, running with the CAMS club, pre 82 Senior - which is what you'd come under - runs with pre 89 Formula 3. They're mainly the 400 fours of the period. Lap times are pretty close, their cornering speed is usually a little better - but they don't accelerate like the big air-cooled bikes. pretty even really. The only problem area is starts where if theres a couple of F3's on the front row, they get told to stay straight as otherwise they'll get run over, LOL.

The really big organisational no-no is mixing disc and drum braked bikes. That's a recipe for disaster.

Well Iím repairing for cost reasons but Iím going to try and acquire another steel tank because fuel pissing out everywhere when the bike is on its side and having to get on the ground to reach the kill switch because the bike is still running, on a live circuit, isnít much fun.

Actually itís funny but you play down these racing incidents because of some inbuilt macho bullshit but it was pretty hairy and I was angry and shaken even the next day.

When youíve buggered up like in the lowside itís understandable, tyre pressures too low, pushing too hard etc but when you get taken out itís different.

Again itís not a matter of blame, everyone concerned from the club to the riders concerned thought they were doing the right thing (you hope) but that doesnít make it less aggravating.

I was definitely slowed by the lowside on Saturday, new tyres, no clear parameters on pressure but by race 1 I was really feeling like Iíd found the right balance and I was ready to push. Unfortunately I buggered up the start, missed the gear change from 1st to second and that put behind and brought me into the clutches of the GP bikes earlier. Still pushed on and was feeling confident, right up until a silver bike appeared under me on the apex of T7 ;)

Going to get some Conti Attacks before I go out again and then weíll push a bit harder.

The club has said it will not mix the GP bikes with P5 UL again which is a consolation.

I am in mona vale, you could just use fibre glass and not carbon fibre as its going to be painted, it wont need much, maybe 450gms, check with the guy doing the repair he will probably have some , you just cant use polyester resin thats all but he will know that. you can pm me if you want to drop by. :)

I don't know how you could repair that without needing to patch over a reasonably big area and feathering it out without showing a raised thickened area, shaping it close to symmetrical to the other side.Getting some backing internally and having that stick after fuel has been in it wouldn't be easy either. Without it being painted you would have no hope of a nice repair.Makes steel tank repairs look easy by comparison.

Post by: Davo on April 03, 2018, 13:06
Not having a pop at the construction, just observing that steel would likely have remained in tact.

The steel tanks that are available will be of varying quality and there would be no guarantee they would not be so thinmfrom rust action that the end result would be the same.

G'day Carlo, more damage than I expected to see.
My limited experance of crashing carbon, It aways fractured, never holed.
Inpregnated carbon cloth on it's own is quite brittle, Boba uses a carbon kevlar cloth, carbon one way kevlar the other.
It's the kevlar that holds it altogether while the carbon fractures.
So being a hole I'd want to back it up with a couple of layers of preformed carbon, epoxyed internally with a fairly good overlap.
Once cured, start building the recess up with layers of cloth overlapping the feathered edge of the hole. The final layer should cover the lot with a good 50-75mm overlap. Use a grinder/dremmal to take about .5mm off the surface to allow for the final layer.
Surface sand and fill any indent with epoxy or body filler then paint.
That's how my uneducated way of thinking would fix it.
I have some carbon/kevar cloth I could send you, also carbon cloth as well as kevlar cloth.
Half a litre of epoxy should do it but buy a litre as it's handy to have on the shelf.
Epoxy is 105 and the hardener is 206 slow cure iirc
If anyone else has another way of going about it I'd be most interested in learning.

Good luck

By backing are you blokes referring to a prehardened piece epoxyed across the hole internally, I guess that would have to pass through the fuel cap and be glued though it as well, bit like a ship in a bottle.This bit would need to be bigger than the hole for overlap obviously, can you get a hand through the removed fuel cap. Like I said fun times.
Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: Davo on April 03, 2018, 14:50
Used to use a piece that would fit through the hole, longer than the width of the hole and just narrow enough to through. Hole in the middle with a knotted piece of string through. Coat the mating surface with epoxy and push it through the hole, pull it tight against the side of the tank with the string and hold tight till the epoxy sets. Cut the string and away you go.

Yep pre hardened profiled to the shape it's fitting into [close], if the hole ends up retangular easy to feed a long narrow piece through or use the filler hole and no you can't get your hand into as the caps Boba uses are small as opposed to mine which I can insert my hand and forearm. Drill a couple of holes in the centre and feed wire through them or insert a screw. Lots of epoxy and  locate the patch into position also being at the most lowest point so position the tank to suit. Hang some weights off the wire to keep some pressure on the joint. Remember epoxy runs to the lowest point.
Once hardened remove wire, holes get filled with the following layers to build up to finish surface min us .5mm for final layer or two.
Something like that.

Iíve bashed the top bearing in. Freezer helped (wasnít in long) but I think iíll heat the head a little bit as well next time.

The socket on the end of the breaker rod seems to work well.

Will have to wait for my lower triple to come back with the tapered bearing installed.

Having had the tank back (repaired not painted) i can see that the seat unit and the tank don't fit well.

Played with a small aftermarket rear guard and decided I didnt have the skills to make it work.

Id love to still be able to ride on road as my mental health is suffering withoit a road ride so positioned some light to see what they could look like. Would be easy enough to bolt on and take off at track.

(http://www.carlobertozzi.com/pics/IMG_2743.JPG)

Might need to make up a thicker seat pad to deal with that lip at back of tank. Way to much stuffing around for my liking but I was kidding myself that it would all go together nicely.

The carbon tank has a slightly thicker 'lip' which means it contacts the panel underneath. As you said it's not a huge issue. I'd love to drop it in to Rob but the distance is the kicker. There's a few guys in Perth that will be able to sort.

Apart from the ownership? Carlo is correct, the c/f tank has a completely different seam to the original metal tank, especially the rear seam over the seat. I had to carve a fair chunk off the seam on mine as it had chopped holes into my beautiful (and expensive) Eldorado cover the first time I fitted them together.

Hi Carlo, looks like you've sorced another tank according to a little birdie I spoke with today.
Shouldn't be too hard to removed material from the seat to clear the tank.

About 50%. Didn't leak but if it did is probably a simple fix with 2 pack epoxy. I don't think that a trim will help in your case as the seam runs a different line to the original metal. You may need to lower the rear end of the tank, if possible, or alternately raise the seat to sit higher than the seam.

Thanks. Going to try trimming the tail unit and a thicker seat pad, will be easier that trimming the seam I think. To be fair Iím going to run it Ďas isí initially anyway for a few kilometres  just to see if it all works and nothing breaks/falls off.

So it seems like my old triple clamp could have been from a 74-75 Ducati 850 GT.

The bottom clamp wasnít exactly right either - witnessed by the weird bump stop.

So hopefully when I have it back together the steering should be better. (Quicker / lighter, hopefully no negative impact on stability)

Tried to get the bike to the painter today but it started cutting out when riding. Would die like the kill switch had been applied but then would start again, run for while then cut out. The length of time it would run each time gradually decreased. Best guess it's a loose Earth wire somewhere but hopefully I'll be able to find it.

Try giving the earth connection wires to the battery a feeeen good TUG, those wires have stuffed me good on more than one occasion. They like to intermittently loose connection at any, well, connection around there. Make sure your battery doesn't move as well, that's what would loosen mine. Wiggle those wires as well, there maybe an internal brake behind the insulation. Mine would go great for a month and then suddenly stop for no apparent reason, and after 20 minutes of fiddling start again with no apparent fix done and run great for another month. You do finally find it when it stops for good.

Got to a country servo, unloaded the bike and pulled off all the bloody plastics to get to the electrics after checking all the easily get at stuff. Yep, loose wire in the sasche, tightened it, thought job done, put the bike back together and reloaded. Damn thing wouldn't start. Push start from a mate and we were off, bike ran faultlessly all weekend except needed push starting unless parked on a hill. Got home and had a quick look thinking I was up for a new starter motor. The starter solenoid wire had been knocked off during our search for the intermittent fault :-[

Just finished watching Mondays Supersport highlights from the IOMTT. I'm a relatively recent convert to the TT (last 8 years) and I'm always excited to watch it but the number of deaths does increasingly weigh on my mind.

Don't get me wrong, I get the concept , even at the clubman level we know and accept the risks of racing and Ive certainly had my share of broken bones and head trauma but the inevitability of death at the TT is something else entirely.

I'm in awe of not only the sheer riding skill but the mental capacity to maintain that level of concentration for 4-37miles on a road course. One fuck up could be your last.

After hearing of a 26yr old who lost his life in the Supersport race on Monday I have my fingers crossed that everyone else comes home safe.

Set the forks up evenly in the triple last night. Like most times where I have to make fine measurements I struggle, even with a digital gauge thing. Need to get a smaller unit, maybe just very small metal ruler.

Need to get a replacement bolt for the gear side reset, it's so badly bent I'm not even sure if I can get it out. It'll survive for now but definitely on the toDo list.

So while the bike is away being fettked I have to decide on a paint scheme. The simplest us to go for a straight orange, although the last time around I felt that was a bit flat so looking to lift it a tiny bit. I like the slightly metallic finish of Mikes Motodd so might see if we can keep the brighter orange but add a tiny bit of metal flake.

Then lokking at past race bikes they had some pretty ugly decals (TOTAL) so don't provide much inspiration. I quite like the blue stripe that has appeared as homage to the V6 and I think I'll have that applied in vinyl, along with the racing number panels.

If anyone sees any inspiring paint jobs though I'm keen to see them.

I went with the painted-on LAVERDA lettering on the tank. It looks good but was a bit of a fiddle to mask and paint. If I were to do it again I reckon I'd go for pre-cut vinyl stickers.

Have ordered a set of pipes from Malcolm Cox and although excitement is matched by pain in my wallet I'm hopeful they're a good investment. They certainly won't be seeing the track.

Greg Parish at DAM Laverda has once again come up with the goods on various things including a screen for the bike. I was hoping that Eagle Screens which is a local WA business would be able to make one but no dice. Greg's online store is working well and he's generous with his advice and very prompt with his shipping.
https://damclassicracing.com.au

Every weekend I'm off the road at the moment is painful although MotoGP helped distract me a little this weekend and next weekend I'm taking the Aprilia to the track, albeit not racing just tuning.

The big bingle last time out has knocked the lights in the clocks all over the place, not only is the gen light on permanently but the entire left clock now flashes when the indicators are on. Not visible during the day but intensely annoying at night. So might need to go back to the shop as well!!

I think I'll stick to racing the Aprilia if anything at all. Bit over the racing scene at the moment anyway and without a track in the metro area it's a struggle to get the time to race.

Playing with the mounting of the lights. New seat pan back tomorrow to go off to upholsterers.

The placement of the indicators is going to be interesting. Rear pretty standard but at the front going to mount them on the fairing cross stay. The small indicators themselves are interesting as they double as stop lights at back and driving lights at front.

Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: Dellortoman on June 27, 2018, 00:20
I made a bracket that bolts to the front of the fairing and all the road-going hardware mounts onto that - headlights, indicators and horn. The whole assembly is attached with 2 x M6 bolts, and all the electrical connections are via a 6-pin connector plug. 

The tail/brake light, rear indicators and number plate are on a similar assembly that can be quickly removed. So the bike can be converted from road-legal to track-ready in minutes. For serious track work, it takes a bit longer because the wheels are swapped to fit track tyres.

That's a really nice job Carlo.  I hope there's enough padding so those nuts don't dig into your nuts  :D

Pat, your carbon fibre seat is pretty much exactly how I did mine. Access hole in the tail piece, and Velcro to hold the upholstery on.

Note to the Velcro haters:  The Velcro works perfectly well.  The seat never moves out of place, even with the pilot climbing all over the bike and hanging off in corners.  The advantage is quick and easy access to the tail storage.

The issues I have had with tapes is probably long ago using the wrong or just crap tape long ago. Some of that latest 3M stuff can virtually hold the weight of a car. We used this double-sided tape once that was so thin you could hardly see it and it was hugely strong.

So you will be drilling the screen, that's an operation that has some risks including getting the holes to aline. I watched the Hand Crafted bloke do mine and expected he would use the fairing as a temperate and drill through both at the same time but what he did was use a bunch of spring-loaded oversized vice grips like things to hold both together and mark them on the screen and drill the screen alone. Ask for some plastic nuts and bolts the right dia and length if yours are crook. There are a few technics to drill perspex and I don't know whats best, they will crack using the wrong techniques,that I have done.They have 3 types of screen, clear sami smoked that I got and fully smoked.

Standard twist drills cut in very quickly on perspex and often cause cracks and splits. Look up brass drill on Google and knock the cutting edge back on your drill bit. Masking tape over the hole and CRC also helps. Take it slowly too. If I only have a couple of holes and no drill prepared I use reverse gear on the drill.

Post by: Dellortoman on July 02, 2018, 06:56
I got fully smoked.

Yes, fully smoked kippers have more flavour  :D

The first fairing screen I ever fitted (on my MHR Ducati), I cracked the bloody thing when drilling one of the holes. Since then I've learned to do it without cracking the screen. I've done a quite a few bike fairing bubbles as well as boat windows now without cracking any of them.

My method is to drill the fairing first. I then mount the windscreen bubble with spring-loaded clamps as Vince described, then drill the Perspex through the pre-drilled holes in the fairing. It's a good idea to wrap the jaws of the clamps with electrical tape to avoid scratching the screen.

I drill the front centre hole first, put a bolt and nut in it and nip it up so the screen is clamped fully home. Then move to subsequent holes working from the centre outwards, re-checking alignment each time and bolting each hole as it's drilled.  Fixing each hole with a nut and bolt as you go prevents the fairing from slipping in the clamps and also pulls the Perspex into its final position, so the next hole is properly aligned.

You can buy special drills for Perspex that won't grab and crack the plastic, but with small hole sizes you can get away with multi-purpose drill bits if you're careful. The main risk is when the drill bit just breaks through the surface on the exit side. The bit can catch on the edge of the hole and suddenly pull itself through, cracking the plastic. The way to avoid that is to clamp a piece of scrap Perspex or hardwood behind the spot where you're drilling, which will stop the drill busting through. Drill with high speed and gentle pressure.

Somebody told me years ago that it's a good idea with acrylic windscreens to over-size the holes. The reason is to allow room for movement due to thermal expansion. Acrylic has about double the expansion coefficient of fibreglass and about 3 times that of Carbon Epoxy. So there can be a substantial dimension mis-match over the length of the bolted joint, especially if the bike is parked in the sun on a hot day. If the bolts are a tight fit in the holes, it can put the screen under a bit of stress. A drill size that's 1mm or 1/16" bigger than the bolt size will give enough clearance for expansion.

Post by: Vince on July 02, 2018, 07:08
Clamping and supporting the other side your drilling from with a block is whats required in kitchen work, laminex ect, so you don't blow through and make a huge exit hole, never thought of that with perspex, I thought the biggest risk was being so close to the edge and the torque of the bit causing the fractures. I have heard of changing the bit end cutters angle, I don't go there. Ruined too many bits attempting to sharpen them over the years, I don't have the nack. I was very happy Hand Craft bloke did the drilling, his problem if he cracked it. He didnt obviously, would have done thousands.

Post by: motoddrob on July 02, 2018, 07:22
My rule of thumb is any drill bit bigger that say 4-5mm I remove the cutting edge of the drill, so it scrapes rather than cuts. Burning a hole through with a hot drill bit will fuck with the perspex and will craze around the area affected.

The plastics drill bits have a steep angle on the cutting tip, approx. 30-45 deg.  Looks easy enough to grind one by hand, the plastic is soft so a really sharp edge probably isn't that critical.

Post by: Dellortoman on July 03, 2018, 04:08
If you're into re-sharpening your own drill bits (an essential skill if you use drills a lot), it's not difficult to grind the angles for drilling plastic.

General purpose HHS drill bits typically come with a 118 deg point angle and around 10 deg relief angle (aka chisel, or lip angle).

What you need for acrylic is a very sharp point angle (about 60 deg) and pretty much zero relief angle. Zero relief angle is actually a conical point on the drill bit, so pretty easy to do by hand. Just hold the drill bit at 30 deg to the side of the grinding wheel and rotate it in your fingers until you have a point. The best analogy I can give is that the drill bit should end up looking like it was sharpened in a pencil sharpener. Conical tip and very pointy.

The reason for the low relief angle is so that the drill only takes very small bites out of the plastic on each revolution and doesn't pull itself through the work. But the drill is still cutting rather than melting its way through with friction.

Use the proper bit as described. Or I have found a dremel bit works as well without cracking.  When I bought my RGS Screen from Gustofason, it came with a bit.

+1 on Henry's dremel connection.

The dremel bits do work very well, but if too small I have a tiny chuck that goes in my dremel > I mount a dull drill bit in that > drill at high rpm and low pressure and a light pecking action. Much tried and tested as I had a lipped screen on an FJ1200 that buffeted badly, the screen was eventually full of experimental holes! No cracking. Never truly fixed the buffeting though.

Being unable to ride for the last 3 weeks has been almost unbearable. Having got the bike to the point where it could be ridden and then to have to give it up again was hard. The painter can get fucked for a bit cause I need my fix. Being away in Sydney for a large part of that time has made it easier and Ive been able to get a screen after pissing around for weeks in Perth to get one made. You Eastern states boys don't know how good you've got it!

The rough brakctes are all replaced and most importantly..wait for it...the neutral light now works (and the other aptly named idiot lights). The endurance lights are well mounted close to fairing exactly as I wanted. The indicators will be black front and back instead of the polished alloy that are on the back. It still bears the scars of its short racing life but it adds to the character (for now).

The high beam switch switches from the twin LEDs to the twin yellow lamps.

A few tasks that are on my mind now to complete the rehabilitation.

1. The bolt retaining the gear side rearset footoeg needs replacing as it's slightly bent and it's very hard to get the correct amount of free play with the lever and the peg be securely mounted.

2. The fairing is a little flimsy and the upper wings and screen move a little too much for my liking. I note that the new screen I have seems to be more rigidity but will look at how I can brace.

3. Rear brake up to its shenanigans again but it's an alignment thing not air as it started when I made a change to rear wheel alignment and lazily only loosened one caliper bolt. (Have to remember how to get the other one loose)

Living having working idiot lights back!!!

There are bevel and Pantah fairing brackets that mount through a hole in the middle top of the steering head nut that take a lot of the fairing upper and screen bounce out,maybe available through Gowanlochs in Sydney. Check the dimensions between that nut and where it might bolt to the fairing so its high enough and wide enough, its pretty easy to mod the braket it to fit.

When you've been steering about a job for a week but the bikes 4500km away the first thing you do is get off the flight at midnight and sort out your steering head washers and adjustment. All done now and fork brace off too. Can't wait to ride in the morning.

Ye pretty much over it today. Runs fine then just dies. Have checked loose fuses, battery connections, other earth's, ignitech earth and nothing obviously wrong.

had a fault like that once in another make, would run fine then start to back fire etc, when a fitting a new ignition system I found  a break in one of the wires about 30mm up inside the insulation.

Yes Iím going to revisit the ignitech wiring.

Also the guys have made some suggestions in technical around the ignition lock.

Thereís been some work done up around the front recently. Perhaps I managed to pull something while doing the front screen.

To me it feels exactly like the bad earth/loose battery connection I had previously. It does misfire or stutter a bit first although not consistently.

Next voyage of discovery is how to find and troubleshoot this lot! At least Iím starting with a wiring diagram this time!

The short answer ...  No.

It doesn't replace the relays that you have for lights and horn. It's just a fancy fuse board with a relay mounted on the board to provide power to a set switched fuse positions.

If you want to replace relays, look at something like the Motogadget M-Unit.

Ok thanks will take a look there's a couple of threads on here with the pros and cons.

Did around 130km today, bike stalled only twice and both times when LED were on, the rest of the time I rode with the yellows and no problem.

So going to have a good look at the relays and make sure they are all working and go from there.

I HAVE ABSOLUTELY NO IDEA WHY THIS PIC INSISTS ON BEING SIDEWAYS!

Ha! That seems somehow wrong for a 40yr old bike! Will have a look and see what it can do.

Swapped out the relays for the yellow and LED headlights today just to elimate them.

I also want to elimate earthing from the body of the LED which uses a bracket mounted on the front brake switch thingo. It's a process of elimination I guess.

Cool plate.

In NSW I think JOTA is/was on Crispin's black and gold (79?) bike IIRC.  In ACT I don't ever recall custom plates being available for bikes.

These days most VIC/NSW bikes are moving onto histroic rego.  Assuming you've got 2 or 3 running bikes (and most do) you'd be mad not to.  ACT is - at this stage - still pretty expensive and limited in comparison, as is Tassie from what I know.

Back to NSW today but as it continues to piss down with rain I'm not suffering too much! The weekend looking a bit brighter thankfully. Trying to get to the painter, so hopefully, it holds. Don't mind riding in the rain but I hate cleaning. Might pick up a new helmet this weekend as I'm down for round 2 of MCRCWA champs the folllowing weekend on the Aprillia and the trusty AGV has started to disintegrate, plus she had a glancing blow when I went down in the HCMC race.

Some good news from our local metro track, Barbagallo, they have signed a deal for the FX Superbike guys to run 30 track days in the year starting in October. I get to be on the invitation list to do a trial run at the end of August which will be fun, if a little nerve wracking having not ridden there for two years almost.

So what's the point of the combined relay? Is it for the main circuit (which currently has a blue fuse (30A?) and fuses in one? So it's just saving me one relay? Would make more sense if it could handle more than one role.

It's just there to provide power to anything that switches on with the ignition, such as the ignition system itself, lights, horn, indicators, starter relay, accessory plugs, etc. Presumably so that all such electrical loads don't have to go through the ignition switch. The ignition switch only has to provide a low current signal to switch the relay on, avoiding the overheating problem that your ignition switch suffered. There's probably not crowds of motorcycle electricians beating a path to his door to get such a fuse board/relay combo, but I guess it would appeal to some.

Hmmm. I vaguely recall comments from Cosi about dropping it on the track for the 1st time when you were originally thinking about racing  :laugh:

I was feeling more affluent at the time!

 The irony of that day was low-side was survived well with just a scratched fairing and slider but I wasn't expecting to get into a dog fight with 125GP idjits which is what cause the big crash.

Also underestimated how much is miss not having it on the road. So Aprilia will have to cater for my track urges.

I did a quick search for his post, couldn't find it, lost interest and deleted mine. Racing is a very expensive hobby in the first place as you are probably well aware. Replacing and repairing 40yo parts, well...

And the bike is such a pleasure to ride on country roads.

Excuse my ignorance but I three active relays: have yellow headlights on one relay, LED and horn on another and the ignition on another. So if I was to install this on my bike how many relays do I actually need in addition to the one in the Fuzeblock? (Sounds like 10A max is the issue?)

Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: Dellortoman on July 26, 2018, 02:08
OK, you could get rid of the relay for the ignition and run the ignition directly from the relay on the fuse board.
The headlight will still need a relay to take the load off the handlebar switch.
I'm not sure what the LED does, and why it is connected in parallel with the horn. Do you have LED warning lights that come on when you press the horn button? Anyway, whatever that circuit does, you'll still need that relay.

The wife's Cagiva Alazzura had all the electrics fed through a relay that was switched by the ignition key; seemed like a good idea until the relay shat itself. Real good fun pulling the relay apart and holding the contacts on with insulation tape during peak hour traffic on Spit Road , Mossman.
Didn't help either when trying to bump start the thing with a flat battery >:D.

Instead of high and low beam he has 2 sets of lights, LED and Marchals. By the sound of it LED main beam in circuit with his horns and Marchals for high beam.

When I rewired the bike with new horns I kept blowing the fuse every time the horns were operated, ended up running only 1 horn.

Post by: Dellortoman on July 26, 2018, 03:35
Hmm, OK. So how can the horns and LED lights on the same relay?

Presumably they don't come on together when the horn button or high beam switch is operated.

Only way it can work is if the relay is before the switches, which defeats the purpose of the relay in the first place.

No idea but when I pull the relay the horn and LEDs donít work. Neither has an impact on the other when on but hey ho they could be wired up wrong ;)

The power and earth comes into the relay and then goes out to the device. Have never thought to check (Ďwhatís that I hear you say?)

The inference on this new fuzeblock is that it can handle multiple devices on same relay of up to 10A x 3.

That sounds strange! Power should go from battery, through a fuse, through the relay and on to the device. The other side of the device should go to earth.

Yes the power comes via a fused source, there is an earth wire to each relay though.

With the wiring for the horn I think it should be different than shown as the earth button is direct to earth on the handlebar. Perhaps it should go:-

+ve from ignition switch - 86 then 85 to horn button/switch. Rest as shown. But I am sure Cam will correct me as elecktrickery is not my forte.

The LED lights should be wired as per the diagram, ie, ignition - light switch - relay 86 --- 85 - LED lights - Earth,  so should not be sharing the same relay as the horn

Post by: cbertozz on July 26, 2018, 18:35
So the first thing that appears to be wrong is that the earth instead of being on 85 is on 86. (Assuming the Narva diagram is correct, and it's possible it's not.

So on further reading:

"The relay types without integrated diode may work even if the coil pins are connected opposite (doesn't matter where is connected positive, i.e. negative pole of the coil pins). But, in the case when is used relay with integrated diode, you must be careful how connecting the relay, pin 85 to negative, and pin 86 to positive pole. If you connect opposite, it may produce a fuse breakdown or some other element breakdown into the related electrical circuit where the relay is connected."

As my relay appear to have a resistor not a diode it's probably OK but will see if it can find some more on the subject.

The connection to the switch is on 85, 30 & 87 appear to be correct.

The inference on this new fuzeblock is that it can handle multiple devices on same relay of up to 10A x 3.

Your inference is partially correct. Yes, you can run several circuits off the (relay) switched outputs on the fuse board. But, you can only reduce the current and voltage drop through handlebar switch wiring by using a separate relay for each switched device. If your horn and lights are on the same relay, it's not wired properly. Although it works as expected when you hit the switches, you're not getting any benefit from the relay system.

Although there are conventions as to how the relay connections are made, in reality it doesn't matter which way you connect the signal pins 85 and 86 that activate the magnetic switch. Nor does it matter which way you connect the load pins 30 and 87 that switch your device on and off. The only thing that matters is not to mix up the signal and load circuits.

Forget about integrated diodes and resistors in relays. The relays you're using don't have them, and you'll only confuse yourself.


Title: Re: Laverda Jota Ownership, second time around. (ramblings)
Post by: cbertozz on July 27, 2018, 05:49
Ok that makes sense. So you'd use the fuzebox with relay for the ignition switch circuit?

Ideal if you want to really simplify wiring and gauge of wire.
Not so useful if you want to retain all original functions (like being able to switch lights between off, pilot and on).

My wife had a Cagiva Alazurra 650, the ignition was wired through a relay; she got a flat battery one day and of course there wasn't enough current left to activate the relay so we couldn't bump-start it. Fortunately somebody in a car stopped and we got it going with jumper leads.

And then you can go the other way, there is a well-known mod for Pantahs where a relay is added because without it all the juice goes to the starter motor and that doesn't leave enough for the plugs to spark.
