I bought a brand new battery maybe 4 months and had no problems. Past 2 weeks I left the key in the ignition (everything off of course) and after a while the power trying to start my bike slowly started to diminish. It's to the point where the headlights and tai lights are the only thing that's on. I'll flip the red ignition switch and it sounds like its struggling an when I try to start it up, nothing. No sound at all. My friend said it could be the alternator or rectifier? I just hope I made a silly mistake by leaving the keys in and a simple charge will fix everything!
Btw I have a 2002 vfr800fi
