okay, i was having trouble, and i thought it was my battery, but it looks like i was wrong. i noticed my headlight dimming more than usual when i stopped, and then she'd stall. no problems running. after some advice from fred, she was working fine, i had her idling on the stand. but riding today, she had the same problem, and i noticed that the headlight was flickering even as i was riding. it seemed to go in steps, bright, not so bright, dim, then bright again.
