Feckin steering head, honestly if I could invent something to securely tighten this exactly right I'd be a happy man. Not sure what I did wrong the last time I tightened it up!? Maybe everything needed to tweaked after new clamps or maybe I just didn't tighten it.

The top and bottom nuts I think must act like lock nuts and tighten against each other, the triple trees probably vary in thickness. Any changes to mine would need a few goes to get right, Not holding the bottom nut with a thin spanner would have it move when tightening the top nut, even when it's held tightening the top nut would have my final adjustment get too tight. I would have to allow some slack to get it finally right. It is a pain to do.

Yes its not rocket science just fiddly and to do it properly you have to take the wheel off. I took wheel, guard, brace and calipers off and then felt for the play, it was tiny but clearly amplified under brakes even if it wasn't obvious rolling along.

The bottom, top and even the clamp has a small impact. If it's locked up properly the top nut should keep it all in place for quite a while.

I never remove anything from the front end other than for access to the adjuster and locknut, just jack up the front and make sure that nothing is restricting free swing of the front end (cables, wiring, steering stop etc). If you can actually detect movement (backwards and forwards) at the end of the forks it is way loose. If they are so tight that I can actually feel resistance in the bearings, I back them off a bit until it is free, then fully tighten the locknut - whatever system there is - and check again. Usually the locknut will press the adjuster nut down and it will be too tight again as Vince says, so I undo it and loosen a tad and nip up the adjuster again and feel it, might take a couple of goes. Same principle on a Laverda as any other bike I have done. And you are right, shouldn't need to be a regular adjustment, other than that new bearings sometimes loosen very slightly after a short time, that's why it is always an item on first service list for new bikes.

Ye I don't normally remove everything but I wanted to be 100% sure that it was the steering head and not something else.

Noticed an unsettling speed wobble feeling yesterday. Nothing big, felt like it was tyres initially but checked the pressures. The other issue might be the suspension, was playing with high speed compression on the rear. Or perhaps it's the fork brace. Apart from that the bike handles well. Note to self, stop fiddling.

Good advice, Carlo - I'd take it!  :-* Once you like the way it feels, time to leave well enough alone!
What ... leave it standard??!!

JUST        ONE       MORE       AND      IT        WILL      BE       PERFECT
I am hopefully on the home stretch, mine still is a touch harsh on square-edged bumps so it half a turn softer till I like it. I started at 4 turns and am at 3 1/2 but cannot test until I am back in Sydney, that's the blue spring. Rear-wheel bearings first tough. I also am going to release one shock at the top and see why I am not getting much travel, I have gone up in shock spring strenth and initially, it was ok but after the Oxley run I am not so sure. It seems to get super hard at 50mm of travel.

Also don't ride when you are feeling hungover as the bike feels completely different. (Read: bad). It's cold and blustery today - I won't miss the wind in WA, it spoils many a ride even when it's a beautiful sunny day.

And you don't even have to pedal the bloody thing, Carlo! I did 85ks on the treadlie this morning - 5 deg when I left, half the ride with a (hero) tailwind, the other half with a (cowering) headwind.

I remember riding the SF across the Nulla with about two days of very strong right shoulder headwinds, unrelenting, no flora to attenuate the wond - so many km barely changing direction - my neck ached for a week afterwards!
