My 2007 gsxr 750 won't start. I turn the key hear the normal noise (fuel pump) and try to start and nothing happens. The battery is good. I tried to jump it with my car and still nothing. While the key is on I don't see f1 on the screen. I only see a red light. Before I put it in the shop I would like any suggestions. I think it's a switch or sensor but don't know wich one. Anyone have this problem b4?
