I´m just now working on the valve clearances, shim sizes mid-process:
On the M800, with +1 mm inlets from Kämna, I have the following:
Closers: 6.73 / 6.95.
Openers: 4.57 / 4.71.
On the ST2:
Closers: 6.45 / 7.39 / 6.70 / 7.14 / 6.70.
Openers: 3.22 / 4.18 / 3.01 / 4.43.
Very conviniently I have access to a small flat grinder, so I try to find a (closer) shim that´s slightly too thick, and grind to size. In my experience, especially with collets, it´s not very practical to go by sizes alone, as shims with the same measured thickness can give uite different clearances.
So far, I´ve not run out of "thicker" closers to start with.
