I have a 2000 Valkyrie I/S with a Motor Trike kit on it. It has a MPA 150/70/17 rear tire on the front, and it throws my speedometer off by 4-5 miles. Is there anything I can do to get closer to the correct speed. Right now, when I am showing 70 on the speedometer, I am actually only doing about 65-66(according to my gps).
I've owned (& ridden for myself) a '97 Tourer & a '98 Triked Standard. I also re-habbed (bought/repaired/sold) four others. Every one of them had the same speedometer discrepancy. Even when dark-sided, I never went short enough on the tire to make much difference.
I just had to learn to ride, figuring in the 5 mph fast reading.
