[QUOTE="zrxrider, post: 1321644, member: 99642"] I'm trying to figure out what to do. I have this new to me 2000 yz125. Its fouling plugs but runs well when it starts. It was never rebuild so I figured i'd pull the topend to take a look. The piston looks great with no marks at all, the cyl. still has the hone marks. The ring end gap was like .035 or so. Also there was a LOT of "goo" under the cover for the power valves. Do you think the ring was just really bad?? Would it be ok to just replace the ring, hone the cyl., add new gaskets and call it a day? [/QUOTE]
