[QUOTE="RobbyB, post: 1365600, member: 110302"] Circlips are both there. The crank and rod bearings were all done, with a new rod. The material must have been soft as there is no damage to the cylinder where it caught. There are about 7-8 very small nicks in the head surface. I'm wondering if I should just pull the motor and wash out anything that could be in the bottom end, if anything now. I've never had a case apart to do a crank, but I can't imagine how material could be left in there after a rebuild. Are there places where a small pc of pist could hide? If it wasn't for the nicks in the head I might think that the piston caught the port. I saw a pic of a piston on another thread that looked exactly like what I have here and they claimed that the piston caught the port. Thanks/. [/QUOTE]
