I left work yesterday and realized that I had left my key in the bike since I came back from lunch. I was completely dead. The Odometer would not even light up. I rolled it down a hill and popped the clutch to get it started. I had it running for about 45 minutes after that. I got home and turned it off and it started back up the 3 times that I tried. I just went outside and it would not start. This was about 30 hours later. The lights would come on but it would not crank. Any suggestions?
