Need Help with Lurching 2005 883C
I've been riding a 1993 883 for the past year, and just convinced a buddy to get a bike. He picked up a 2005 883C with about 2800 miles on it. We rode about 200 miles the other day, and he mentioned that the bike seemed to lurch when he was up around 70-75 MPH. I figured it was just the fact that it was a stock bike (no after market mods of any kind).
Yesterday, we changed the oil and now the damn thing lurches like a motherf**ker. It doesn't do it at any set RPM/load. Just seems that if you roll on the throttle sometimes the bike hesitates, lurches a couple of times and then gets going. Also, the speedo resets when this happens (the needle sweeps the dial and the lights go out).
Any ideas? His battery IS VERY WEAK, but I'm getting good voltage readings when the bike is on. Ive checked for loose connections at the battery or blown fuses, and haven't found any.
