Well today my buddy and i got the jug off, the cylender dose not look bad at all! No scrapes or marks or anything. So i am almost sure its fine.. But the piston it really dose not look bad besides the top around the out side it looks like there are little groves its not smooth. And when we started it up the other day it started but it sounded really bad almost like nails are in there... I think its blown and i am not sure why it blew.. I know the carb was REALLY dirty and i know my buddy isnt the smartest rider he likes to pin it alot!

x2, if they dont have any signifigant play, and it spins fine, you can bring your cylinder to a shop and get it honed, buy a new piston, and clean your carb/
