I just bought a 2000 F4 yesterday. I got home and it started right up, but on the ride home I had the kickstand down and it bent. So I strapped the bike up straight at home and tried to take the kickstand off, but I couldn't break it loose. However the stand was up for probably 20 minutes and when I went to start it, the battery was dead. Could a kickstand being up drain my battery when the bike isn't running? It started right up when I got home but after working on the stand it is completely dead. Do bikes have alternators? I imagine I'll have to throw a trickle charger on it if they don't have alt's. BTW, the key was off while I was working on it. Any info is greatly appreciated.
