My Gl650 used to give me fits when starting. I too had to cross my fingers, do the kill switch trick etc. A real pain and potentially damaging to the starter clutch. I did the ground strap fix and the starter really spins the motor with no problem. It never kicks back now. When the motor is warm I don't even hear the starter turn, the motor just jumps to life. The starter is easy to remove and reinstall, and the ground strap fix is easy to do.
