Hello! Yesterday, a friend of mine (a ZX-10R owner) rode to my place to pay me a visit. It was a classic, routine riding with no problems. After a few hours, when he was about to leave, he noticed a very strange noize when his bike's engine started (something like a buzz or close to that) and the bike died immediately. It's not a battery problem, because we tried to feed it through cables. I don't have a video because we never expect that something like that was going to happen. Did anyone have a problem like this before? Any suggestions?
