Post by: Stpltn250r on January 12, 2014, 09:41:27 am: How old was the piston? Bore could have been loose and piston came apart. Were you running it hard to your buddies house? Could have detonated on a long pull and suddenly pulling in the clutch in over rev.

It pretty much means you blew it up.

Thank you Mr. Obvious, --> I think he want's to know how it blew up? My first thought thrust washer or bearing, but if he held it wide open for a mile it might be melted piston chunks.

Post by: Jsmitty42 on January 11, 2014, 03:35:24 pm: Well I rode less than a mile down the road to my buddys house. I pulled in, shut off my quad and we sat around for about 20 minutes. When I went to start it, it was seized :( so i got it home took the top end off and the piston was all messed up at the top. It was like chipped in a lot of places and so was the head. What does that mean?
