I am in desperate need of some help. I went riding last night and about 30 minutes in I stopped at a gas station. After I did what I was there for, I got back on my bike and it wouldn't start. It sounded like a dead battery and I had that little lightning bolt icon on my dash. So I called a friend and he came a few hours later to trailer it but he wanted to try to bump start it. So he tried several times and on the last attempt, the shifter locked in second gear. Any idea what it could be? Someone mentioned shift forks/shift dogs and regulator/rectifier.
