Thanks Noel!

Did you change original clam bolts which are holding cam itself? I have read several posts about challenges to loosen those when adjusting valve clearances.

You don't need to touch those bolts when adjusting the valves

I mean these bolts which are shown in this thread:

http://www.mvagusta.net/forum/20-mai...er-things.html

Would be difficult to adjust with shims without access to valve cups?

I only see the intake cam locked in place. What if you have to shim the intake? Do you lock one at a time? Please expand. I am currently doing this, or trying...

This is locking the chain once timed correctly after shims replaced....prevents the chain from slipping when the tensioner is installed....which can and does happen.

I used to be fast....now I just dream about it.

I looped a thick tie-rap around the chain underneath the ex-cam-shaft and tensioned it with one side under the in-cam-shaft and one side over it. I used a tie-rap because it keeps tension on the chain. The tie-rap rests at the location of the tensioner. *edit* Off course this only goes for tensioner maintenance.

Thank you for the great pics. Yes I can see how this would work also for the valve clearance shim replacement procedure!
