So my 2008 M1000 started missing and sputtering on my last ride. Got it home and when I fired it up I have VOLT come up on the speedo when I touch the throttle. The miss/sputter is still there as well and seems like the idle is pretty rough. I checked the ground and it was loose. I tightened it up hoping the problem would go away, it didn't. I looked for bare/worn wires but didn't see any. Any help on where to look next or ideas would be deeply appreciated. Thanks in advance
