I built a sled for a kid that lives down the street from me on the cheap (really cheap), and I am looking for a setup. I started with a 97 XC chassis put a 121x15x2 with seven tooth drivers on it. I put the engine and primary clutch from his 94 XLT in it and switched the chain and gears to hyvo set so I have more options laying around for set up. The secondary is stock and from the 97 XC I decided on that because if the belt tension adjustment. I know I can't have the best of everything but I am trying to get his sled at least competitive when he is lake racing his buddies but still keep the torque to get his track speed up fast when he is out riding with My friends and I off trail.
