I was looking for more power found a low hour 650 Husaberg 65 hp. One small problem they put the chain on the wrong side. Thought about a new kit right drive long track but knew that was out of budget. I have a 13 kit so here is how I made it work and to go back to left drive move the sprocket and spacers. First order a 137 2.3 track with some Ice Age rails, next layout new side plates went 1/4" trying to eliminate some flex. Had to make this first modification to the frame to move tensioner to right side. Went with 1 inch shaft 4140 made a sprocket shaft also 1 inch. Used Fafiner GYA100RRB bearings with the greasable G52MSA/MSB flangett these bearings are adjustable for alignment also the same bearing used on the track and jackshaft on a snowmobile that run for years and thousand of miles. The track and jackshaft both shoulder and lock to sprocket side, the opposite bearing the shaft floats in the bearing so there is no bearing sideloading. All sprockets and brake rotor hub have set screws over the keys, the 17 t drive sprocket has a extended hub with a 2 inch long key. I went with 18 t to 19 t for track drive. the chain case is sealed with this type of idler no slots in frame for snow to get in. Added cross bars to eliminate side flex of plates and tied top of plates to frame eliminating flex. raised the skid up in the frame to lower the bike it is 15 inch from floor to footpeg. I weighed my ST kit 120 lb weighed this 140 lb added 20 lbs maybe 1/4 side plates is overkill but it doesnt flex. Was going to paint side plates but look cool aluminum color.
