Ok, I've got this wierd buzzing sound coming from my 07 cbr125, I was very low on fuel yesterday (below empty) and wasn't able to get any on the way home, made it home thankfully though, anyway I was really tired and left my keys in the ignition and turn on. Went to sleep, woke up a couple of hours later and realised, went to grab them and there was a wierd buzzing noise that seems to be coming from under the seat. I turned the ignition off and back on and the buzzing sound resumes, I'm not seeing the Neutral light light up or anything. I can't start the bike, it just makes that buzzing sound when I try. Any ideas? I'm thinking I killed the battery or something, no idea how to fix it though.
