I have a ’04 XL883 with just over 3,000 miles. The bike rides and runs great. I have been noticing a discrepancy between mine and my wife’s bikes mileage during gas stops. We can ride the same distance and there is always a difference between the two. I really had no idea what was going on until Saturday, while we were waiting to participate in a bike parade I watched my odometer add a tenth of a mile while idling. The bike was in neutral and the clutch was out. After seeing that I revved the motor and saw the mile per hour pointer move up to 5 mph then return to zero. Anyone have any idea why this might be happening?
