Well the other day i was riding with some buddies and i came around a corner and my chain slipped off the rear sproket and jamed up against the crancase with the primary sproket. The motor stopped instantly and i rolled to a stop. After getting the chain out and tightening it back up i started up the quad and it started ticking. Then i rode it around to kind of figure out what it could be and i shifted into second and it was a hard crunching sound and it kept ticking but very abruptly. I'm not sure what it is and any help would be greatly appreciated.

Thanx
