not feel'n the feeler gage -o gosh that's not right

get  your mind out of the gutter

ok my question is that I went to measure the valve clearances last night only to find that my thinest shim .015mm [with in specs] dosn't slip through any of the spots [16 of them] regardless of where I alight the cam. [says to measure when the lobe part is perpendicular to the cyl. head.]

So what's the shim's feeling? Does it kida stick then comes out = that size..or did I just lucky/the clearance is smaler than .015mm?

A feeler gauge is a go no-go gauge.  The key is not to force them.  If it won't fit, it's too big.  If it glides easily, it's too small.  If it's "just right"  you will feel a little drag.

Remember, lubricate the feelers with motor oil and keep them clean.

if your thinest guage doesnt fit then you could have a burnt valve(s) too... but I dont know the clearances by heart so I cant tell if your smallest is small enough.
