Anyone have their 500 randomly shut off? Just happened last night at a stop light......switched the ignition on and off and it started right back up. Was in first at a stop light, clutch pulled in. Totally stationary. I was thinking I could have toggled the on/off switch by accident....but I physically had to toggle the bike off then back on to fire it up again.. Only thing I have done to the bike electrically has been to put a usb adapter on it..connected to the battery directly with a quick connector about half way, so I can tend the battery if I need too..
