I've been through hell with this quad. It was in perfect condition, I went to start it and all I heard was huge knocks. This was back in October. So it ended up being a one way starter clutch, popped a new one in, started right up, but sounded like shit. The timing chain was smacking around so I put a new one in, but now it won't start back up! The quad isn't getting compression and I have no idea why. If anyone knows or may have a clue, PLEASE HELP!!
