Only just spotted your last post. Offer still stands for borrow of micrometer. I've got a spare closing shim that you could practice on too. Will bring them if/when I'm over that way in the near future, or you could collect if you're in the Leicester area.

no rush.. the bike isnt sorn until end of oct... but to be honest could do with your help if you have done it before.. so once i have the bike strippd and the heads off then i can give you a shout if you pm me your number? prob wont be until mid nov though...

Happy to help. I've only done it once before, but went VERY slowly, the main aim being to learn all the angles and pitfalls for future reference (cos I'm NEVER going to sell this bike), so I reckon I've got a pretty good handle on it now. Remind me via pm when you're ready and we can take it from there.
By the way, you mention taking the heads off.....No need for that. Just raise the tank, release the oil cooler fixings (leaving the pipes connected) and remove the rocker covers.
I'm assuming that you have a rear paddock stand so the engine can be turned over via the rear wheel...?

im gonna remove head ans im gonna spray the engine up and put black barrels with aluminium grey heads and crank.... i have the paddock stand.. so it may be eassier once i have sprayed the engine and reassembled.. but i think its probably easier with the head off....

I measured clearances and took my old shims + values for the clearances to my local Ducati dealer (JHP in Cov) and the parts guy measured up my old shims and gave me appropriate sized replacements. Luckily they was a tiny bit oversized, so I carefully ground em down a bit to correct measurements on a bit of 240 carberundum paper.

If the heads are coming off anyway, then doing the valve clearances will be a relative breeze.

Anyone notice in the second vid that he torqued the top left valve cover cap head twice and forgot to torque down the top right...Ooops.

Very interesting vids, wondered how the valve gear worked. Why did he push down the closing rocker to measure the closing clearance though? What force is he trying to overcome?

Theres a closing spring that is looped around the pivot shaft, pushing down on the rocker arm removes any pressure the spring is applying.

But where are you guys getting your shims from what with all this bloody COVID-19 and the likes and bike shops being shut?

I have a natty little Excel file that helps with the calculation if anyone is interested, it's not my work and originally it was used for an ST3. is there a way of uploading a file to the forum?
