[QUOTE="jdbrusch, post: 666244, member: 25926"] I am running a wiseco piston(also sleeved) right now in my bike and the instuctions that came with the kit indicated a clearance of .0025"(.064mm) for cylinder sizes of 60mm to 73mm,I am not sure why they would recommend a tighter fit with a oversized piston in a steel sleeve,maybe because the sleeve has been taken down it will not expand as much??? If possible ask the shop that is doing the boring what they recommend or usually set the clearances at at final honing,its possible the wiseco pistons expand less then the oem kawasaki one which would need less clearance once everything is brought to temp. The main reason for a cold sieze is running the crap out of a cold engine,the piston expands faster than the cylinder and thus you lose the clearance that would have been ok if the engine was allowed to warm up properly.
