The headlight and guage light comes on, it wants to start but it just won't turn over. Sometimes I'll get a good backfire out of it but nothin else. I cleaned the plugs, and tried with the choke open and closed. Could this just be a battery issue? I'm quite a noob to this so I appriciate any help (and your patience). It started in the morning. We rode to my in-laws, and 2 hrs later it wouldn't restart.
