The piston looks bad to me, so does the cylinder. Look close at what looks like a crack in the cylinder, it does not catch on my finger nail, I hope it is repairable. The first pics are of the valve, this is at rest, does this look ok? when I turn it (At the gov. arm) it opens all the way and returns to this position. Is this a kawasaki piston?, is it what came stock? Any feedback greatly appreciated. The crank small end looks to be in spec 24.0 The bottom end feels loose to me, I can rock it, but it measures .018 limit is .020, is the play I feel normal?
