so im riding for the first time this year on my 09 M8 and last year the dealer put a new clutch on it and its working fine, i jump a grid road and start off into a nice field and hammer down on it and it sounded like rocks being crushed and it just rolled to a stop and every time i reved it it just reved and didnt move,i thought maybe i blew a belt so i look, its fine, flip it on its side and i can move the track around, i can also move the rear clutch by hand with out the sled moving, WHAT THE **** HAPPENED here guys
