I feel dumb asking this, but the only stupid question is the one not asked right? My bike sat for about 4 days while I was out of town and when I got back I rode it just on a short ride maybe 20 minutes. Everything worked like a charm, started fine, all lights and electrical worked great. Last night I went to start it up to put it away in the shed and it wouldn't turn over. I know with cars it will kinda give a half crank and then just die when a battery is going dead but you can tell cause the lights will be dim or not working at all. Maybe this is a bike thing, but all the lights were coming on just as bright as can be and I even tried the horn (which worked). Would it be a dying/dead battery if all the lights are still coming on like that or could there be a separate charging issue??

FYI: I was able to clutch start it and rode it around the block and all systems worked fine....it was just in the starting.
