Just bought a used 2009 renegade 800 and rode it 5 miles and blew the belt. Went to pull cover off and the back clutch bolt head was pushed thru the cover. Put new drive belt on and retorqued the bolt down. Everything looks good except put it in gear and very little accelaration and wont go without reving in way up in low gear and then maybe 2 mph is all. With in 100yds that bolt was pushed back out thru the cover. Not sure what problem might be. Any help would be apperciated
