[QUOTE="spanky250, post: 110412, member: 20897"] When I bought my current bike, at the first tear down I discovered the previous owner had aparently blown the engine, and had the cylinder sleeved. The piston-to-cylinder clearance at that time was about .06" at the top and bottom of the cylinder, and about .09" in the middle, obviously needing rebored. So, off to the shop it goes, and it gets reassembled, with a new piston. At the next tear-down, prompted by a loss of compression after only about 30 hours, I find the clearance to be nearly as much as it was the first time. No more of this crap! I bought a new cylinder, and it has been rebuilt 9 times without replating, and it is just now worn to the spec limit. Is a sleeve as good as plating? not by a long shot in my experience. [/QUOTE]
