Ducati Valve adjustment

I got stuck into doing the valve adjustment on the Ducati. You really need to remove the tank, side panels and the rear carb to get good access to the valve covers, oh and the battery, which BTW, was at 12.6Volts - so good.

The front Cylinder :-

Inlet opening measured between 0.005mms and 0.1mms
Exhaust opening between 0.15 and 0.2mms
Closing exhaust 0.05mms
Closing inlet zero measurable clearance but I could turn the shim

The rear cylinder :-

Inlet opening no measurable clearance so less than 0.05mm
Exhaust opening between 0.1 - 0.15
Closing Exhaust 0.05mm (tight)
Closing Inlet 0.05mm (tight)

In my opinion all of the closing shims are about right i.e. very little clearance bordering on the zero, whereas the opening shims definately need some work.

Now I have to do some research about how to remove the rockers and cams(?)  and where to buy shims.
