My brother just burnt the clutch on his Wide Glide. What would cause this? Would this be a defect covered under warranty? Was he just hot rodding it too much? he said he wasin 5th doing about 55mph gunned it to 70mph then shifted to 6th. then the engine seemed to rev to high. he down shifted, down shifted, until 1st gear. Then bike wouldn't shift out of 1st. Dealer said burnt clutch. Any help?
