assuming exhaust given the .01 spec.
i always use the metric spec as its a little more accurate.... so .25mm + - .03mm
so on the tight side of the spec you have .22mm = .00866in
Now question, did the .008 feeler gauge fit, and the .009 did not? if so your gap is bigger than .008 (typically you take the difference between the two feelers for actual gap... so in this case .0085in)... and in all honesty i would not go through the WHOLE process of removing a cam to adjust a valve thats .00016in too tight.... thats so miniscule, and the time and risk of messing up stuff (a messed up cam aint cheap) is not worth it.
That stated, watch it, if its getting tighter than what its at i would shim it.
EDIT- Second question, how many miles on the bike?
