[QUOTE="BlackRaptor, post: 814910, member: 53023"] Hey Guys I still new to the whole bike rebuild thing so i had a couple questions i was hoping someone could answer. My 91 CR250R is 100% stock right down to the top end. I got it from a guy last june and i asked him about it and he said they took it apart and the piston and rings looked fine and weren't in need a being replaced. The bike has great compression and always starts on the first kick and for a stocker bike keeps up pretty good with my newer modded CR so this makes me think that the top end it still fine. But i've heard people say with older top ends the rings can fall apart and mess up the inside of the cylinder. This bike isn't riden too hard i mostly ditch ride and gravel pit ride it so it's not pinned all the time like in racing. So i said all that to ask if this was your bike would you freshin up the top end this winter just to be safe? Thanks. [/QUOTE]
