Recently I rebuilt my front calipers and wired in a USB on my 04 650. When running a wire to the battery it was necessary to lift my tank about an inch in the rear, than secured it back down. When I got everything put back together, and hit the start button wow. the motor instantly revved to the limit before I hit the kill switch. The USB Hot is wired into the heated grips, the Ground to the battery. I pulled the tank, and have looked for anything that may have been knocked off. The throttle operates smoothly. All linkage, and cables operate smoothly. But still, I better have my finger on the kill switch when I hit the start button because it goes instantly to red line. It ran fine before. No sputtering or hard starting. Ran great. I'm at a loss. My mechanical ability's are kind of basic. as I mentioned, rebuilding brakes, new bearings/seals, that sort of stuff. Diagnosing this is a bit beyond me.
