Recently got my license taken away trying to get her fixed up blew her up on the last snow day ran on one cylinder for 2 seconds heard a loud bang and and it shut off cleaned out one plug and rode it home finally went to take it apart and one piston was missing g the skirt and the other was cracked. Crank is out of wack and I was looking to go for a upgrade was thinking about a 4mm crank the pistons ended up being Chinese .2 over I am looking to save as much as possible till I can start working again in a few months when I get my license I ride trails, I have yfz suspension, pro design cool head, stock cabs, v force 4 reeds, recently installed a chariot clutch basket and tusk plates. What exactly would you guys recommend.
