From the factory my odometer was correct and the speedometer was off about 7.2%. The signal for both come from the same sensor. Here is line right off there web page.
Will the SH calibrate both my speedo and odometer?
Yes, but it is not possible to calibrate them separately, as one speed signal drives both the speedometer and the odometer.
You can get 100% accurate speedometer AND 100% accurate odometer only on those bikes, which have zero "speedo-to-odo" error ratio (see FAQ #16) built-in, such as the Yamaha FJR1300.
On most bikes, if the speedo is calibrated to be 100% accurate, the odo will register slightly less miles. While this can be annoying in certain situations, one can always calculate the real distance easily after a long trip.
Alternatively, of course, you can get the factory default indication regardless of the used sprocket ratio: accurate odometer and slightly optimistic speedo.
With our on-line calculator, you can optimize the calibration value easily for either speedo or odo.
