Nobody has a clue how many have wrecked everyones just coming up with these fix ideas. pretty sure you are supposed to break the belt drive in for 150kms so its not like you have to worry about picking up your new sled and heading straight to the hills and then busting it immediatly and needing a chopper out. seems like if they break it happens within the first 100km from what i have read. I would just keep it stock and see if it breaks right away or else ride the damn thing! Dont get so worried people.
Buddy went to quartz for first ride of the year on his Pro! Got to rude dubs out while his sled flew over top of him via chopper with a busted drive shaft!
