I have a 1980 Sortster. I dropped it at a red light during some rain. It bent the forward controls and the turn signal dented the tank. The problem is it will start and run fine for about 10 min, then it dies. Wont restart til it cools. I have changed the coil, plugs, and plug wires. This is very frustrating. I have since aquired a 96 Nostlgia, but would like to get the sportster going again. Any suggestions or advice would be appreciated. I hate to keep nickle and diming it.
