.09mm of shim clearance. Not spec, but OK?

I'm in the process of doing my valves, and one of my extra shims brings my intake valve clearance to .09.  Is that close enough?  There is no way a .10 will go in there, and the .09 barely fits.  Thanks.

that is fine. It should be BETWEEN 0.03mm and 0.08mm. Larger clearance is ok. You want to avoid tight clearance.

.03 and 05 mm BTW you cannot measure it once you pull the shim out, its got oil float.
Though yamaha maxim series which is near identical to these right down to shims that are .5mm smaller diameter run it 7 to 9 exhaust and 5-7 intake.
So by my brilliant deductive reasoning ... presumably you be OK if its exhaust. If it fails though, you will ahve to get warranty work done by yamaha.  O0
Cool.

Looks like I'll go up a shim size since it's on the intake side.
