I offered to help a friend rebuild a 04' Prairie 360 that was smoking like a frieght train. (No it wasn't over filled with oil, just the oposite) No one offers a piston kit for it except Kawasaki. I thought that was odd. After some more investigation I think I have discovered the reason for that is that the sleeve is a coated sleeve and can not be bored. Can anyone confirm or deny this? If it is coated, will a set of rings fix this thing up or is it goign to need a piston and new sleeve?
