Does anybody in the edmonton area have a stock exauhst system laying around for an 06 900 rmk? Also I have one of the bearings that my weights ride on that is ratched out, the clutch weight is hanging up on it. do I need to pull the hole clutch or is there a trick to changing this out?? Please help, i am trying to give this thing to my kid, he's gonna hate me if he cant ride it!
