Well, today I was at the track, and I was riding fine, I came back to the pits for a drink, and when I went to start it back up the starter motor didn't even make a sound. My electrics work fine, my lights turn on and the nuetral light goes on and its bright. I am REALLY starting to hate my EX cause all it does is break, but it's all I can afford right now. What should I do to fix it?

thanks
