Hey guys, we got another tip from an engine restorer that if the 500 is a Montjuic it would have "S1" on the cams.  We checked and it DOES.

Thank you Andy, I'll email Slater.

Re: the 500 tank. Got it drained. Tiny amount of water, maybe a soda cap full. I think the fuel filler cap vent might be plugged. Drained about half or so of the gas out one day, and after it evaporated from the drain pan, the next day I opened the petcocks and got nothing out until I opened the filler cap. Must have developed a fair vacuum from dumping that much fuel at once, if the vent is plugged.

Now I'm wondering if that might have been a factor in the lack of power it exhibited. I though it was a carb problem, but got no change after going through them. I was thinking it was an electronic ignition box problem after that, as I've run into that on other bikes. Now?

Inside of the tank looks good. No obvious rust, just a little bit of residue from the old fuel I think. Fuel appears to have separated to some extent, with lots of powder/particulate sort of debris in the bottom of the drain pan. It might have only been 20 years since I worked on it, as I think that is around the time I pulled the engine out to clean up the frame. And then it sat, following the brain damage.

FYI Guys, the owner is now listing the Laverdas, with new/better pics, separately and under his own account with more modest pricing.  The 1000 is up and the 500 will be up in the next day.

I reckon that Jota would have to be fast. It has a red swing arm and a Ducati front mudguard.  :D

Close-up of the C4 cam and its follower looks like they've run in a sand pit... ::)

The initial pictures from the first eBay listing  shows all hex bolts missing with cam cover resting on the motor, no spark plugs, no chain cover, no carbs with intake uncovered and he says its been like this for 20-25 years. Zoom in on the 4C cam and cam buckets. Does that look iffy or what.

Just looks like a silver anti-seize lube to me, like the Loctite stuff I put a dab of on my spark plug threads.  Owner has put a bit on the lobes and buckets before turning over?  Would be wise.

??


Or... it's lapping compound...  :o ;D


Hopefully the former!

Clearly the bucket is lifting & contacting the cam lobe so time to pull the head!

it doesnt look right to me. Could the owner have attempted a cleanup for pictures?  Remember the cam cover was sitting on the cylinder head unbolted for many years.   :o
