Have a turbo x which has been in a specialized shop because the motor cuts off and the head light does not work. They have put a new harness on the bike but the light still does not work. They have said everything checks out but the light still does not work. I told them to replace the light which they are in the process of doing. The frustration has been they tell me the bike runs without the light but I ride about a mile and the motor cuts off.
