I recently had my WR450 "uncorked" and after some initial jetting problems it's working great. During a recent desert race, I found that my odometer and speedometer are completely screwed! The mileage shown for one of the loops was over 5 miles off. The hour indicator seems to be right but I really haven't tracked that. Is there a way to "reset" the computer or at least calibrate it? Thanks for any assistance!
