Hello, I just done valve shims and now engine is not starting, I bought this engine and never tested, just before fitting in motorcycle I decided to check valve clearance so everything would be done at once, what I found left side Exhaust and Intake was a little of range.... look at my photo I have marked tolerance and everything, could it be that I missed something ? Or I have bought engine without compression? it looks like that I have weak compression, because I could hold with my hand the spark plug hole, DUKE 390 2016
