Hey guys, so the other day I was coming home, got ready to turn into the driveway, down shifted from 3rd to 2nd to 1st and KABAMMM, bike makes this horrible metalic bang, shifter hits me in the bottom of the foot and now it sounds like theres a little guy trying to pound his way out of my case halves with a 3lb sledge hammer. Any thoughts? Thinking it might be a good time to put a set of wiseco pistons in her if the cases need split. The bike had 3rd gear replaced almost 2 years ago when the previous owner had it. I'll be doing all the work myself, so labor charges dont effect me.
