I took my bike out the Sunday before thanksgiving and rode about 120 miles, filled up at the same gas station the next day and went 60 miles to work no problem. I got off work and got about 2 miles down the road and my bike started sputtering real bad. It barely runs at higher rpms. The lights instantly dim, slowly get bright, then instantly dim again while going down the road. Someone told me to check the grounding wire going up into the fairing. I think it might be the plugs. I put d&d exhaust on it and haven't tuned it. I was waiting for the d&d race ECM from ebracing, but they said it would be fine to run it with the stock tune until they came out with the ECM. Didn't sound right to me, but they're the experts. I just hope the valves are fine.
