I recently purchased a 07 Husky TE510 mainly for trail riding with the occassional dual sport ride. Very nice bike, but on my first dual sport ride, I noticed that the odometer was not accurate. The guy I bought it from had a set of supermoto wheels that he put on it. I switched back to the original 18" and 21" wheels. Does anyone know if and how I can calibrate the odometer on this bike to be accurate. If not I am going to be SOL on my next dual sport ride! Is there an after market computer for these bikes? Also, is it just me or is the seat on these bikes a bit hard on the old tush? Please help because I do want to get the finisher's plaque for the Big Bear Dual Sport Ride this July. Any help is most appreciated. Thanks.
