Did you guys know you are supposed to break a new belt in for 50 miles? Not even on belt cover. He will rebuild and go again...it is a Hartman special and a real spanker. Used to be mine but on XP this year which is a blast but miss the quality of Yammie and lots of fun on that sled. Like reverse now...no more lifting sleds. Light is right. Backs are precious. Break in your belts. Goose
