I was out riding and everything was working fine. Rode for about 30 min and as soon as I got to my drive way it just stopped. I thought I accidentally hit the kill switch but I didn't. Now when I press the starter but nothing happens it doesn't turn over or make any noise. When the key is in the ON position all the lights horn and signals work but it doesn't start or do anything when I press the button. Any suggestions as what it could be.
