probably the tensioner. they are about 80 bucks. get a chain while youre at it. there is a a little plate behind the left sidecover where the crank is. you can pull the chain through there to replace it. (you dont have to split the cases but youll have to pull the cam. (easy) the tensioner is a system of little weak springs and bent sheet metal and plastic. it may just need to be adjusted. i have a feeling no one ever adjusts them. congrats! ill have mine up at the fim race. maybe we should get an unofficial race going on sunday night. i was out riding mine yesterday for about an hour. too fun.
