This problem started a while ago, but just getting time to look into it. While driving around town under normal conditions, my busa stalled and wouldn't start. Seemed like the battery was dead, not a hard start or turn over, just barely turned over. I thought the battery was no good so i bought another one. Busa starts up fine, drive it for a while stopping and turning off at different locations and the third or so time it doesn't start. I pop it and drive away and within a mile it starts breaking up a little and again it stalls. Battery dead! Will not start again. I put in someone's battery and it fires right up and drives normally until I get home. HELP!!!!!!! I think the battery is not getting charged? Would that be the rectifier? Some help if possible. Thanks..
