I have a 2004 sportsman 600 twin that I just did a clutch kit on. After, when riding and coming to a stop, a couple times the machine wanted to keep going. I had to hold the brake and I could not shift out of high. After applying throttle it returned to normal. Does anyone know what the problem might be? I know I put the clutches together right and the only difference with the "stock" kit was the springs were longer and a new helix. Also, the engine, exhaust and tires are stock.
