So I replaced regulator,battery and relay on my gen4 and still didnt start. Took it to my friends and was able to diagnose that its the starter motor. I looked on ebay for a used one cause it is an expensive part. Any one have a clue if i can refurbish it instead of buying the whole thing? How can a starter motor go bad at 13k miles? I did flip the bike forward and landed hard on tank and tail thanks to an idiot that cut me off real bad.
