I'm a first time rider and just bought a 2003 Yamaha V-Star 1100. It's been running great. Last night I went for a short ride around the block, pulled in the driveway & went to cut off the engine. It wouldn't turn off I had to disconnect the battery to shut it down. If I try to hook up the battery the bike keeps turning over with the cut off switch in off mode and with no key in the ignition. I don't know what to do.... Help!!!
