Check clearance with a feeler gauge at bottom of the sleeve the exhaust and top, they should be all within spec(between piston/ring and cylinder wall), lmao im having a brain fart also so i dont remember the clearance either, im going to start keeping my clymer up on my desk. What was your compression, that should have told you if theres some problems with clearances. The front/back of the sleeve will probably show more wear than the right/left will, nature of the beast (if its got some hours on it). And yes if it its bored correct and you have a good set of pistons that fits the bore within spec it should clear things, after the first time i would have found out why it happend, not the third time! Get the crank checked out if things are in spec... Goodluck
