[QUOTE="Trfsrfr, post: 216742, member: 3959"] Started digging into the YZ today and noticed that the top piston ring is partially exposed down in the cylinder. It looks like a lot to me, but would like y'alls opinion, is this normal? [ATTACH]31264[/ATTACH] The cylinder mic'd out at 66.4mm, and the new piston is a 66.36. [ATTACH]31265[/ATTACH] [/QUOTE]
