Towards the end of last summer while riding home from work, bike was running great, then when i was coming to a stop the engine just died. After i started going again, i tried to start it back up, it struggled but finally started. But now the exhuast was very loud and had a serious lack of power. I finally got a chance to dig into it, found one of the piston retainer clips had broken and made it's way into the cylinder, where it dug two large gashes into the cyl wall and the piston skirt. Found no evidence of bottom end damage, or the clip. I know there are top end rebuild kits, but will this be ok? Or should i just replace the whole damn thing?
