I just bought a used 2004 America. Seemed to ride just fine. Had 3000 miles on it. Put about 15 miles on it today and parked it. Fired it up a few minutes later and when I went from neutral to 1st it cut off. It does this each time as if the clutch is not engaging. I can roll the bike in gear while holding in the clutch but it turns off each time I try to go from neutral to 1st while its running. Any ideas what the problem might be??
