I was out riding last nite with all of the new snow and was screwing around doing about 15 mph and dumped my 01 zr500efi on its left side. Pushed it back up and it went about 200 yards and died. It would idle somewhat if I held the throttle wide open. A buddy was working the throttle down where the oil pump connects and it started running fine again. No problems rest of the nite and it started right up this morning. What would of caused this to happen? Any ideas would be great. Is it possible that it had something to do with me dumping it over? Thanks
