Sled is a 03 factory mod. Just put a new jug and piston in. Had the headlight out for test ride. Ran for about 5 mins and it quit. It's like I was riding along and somebody hit the killswitch. Has no spark. Was lookin around and didn't see anything. Pulled it over about a minute after it quit and it fired up for about 5 seconds. Decided maybe I had a short somewhere with no headlight so I grabbed the headlight and put it in. Fired right up. Rode about 500 feet and same crap. *%@???
