Adding miles to an odometer
But who knows ... 4 MPH (keep it slow) for ~50 Hours (OP says two days) ... still wouldn't use that

Scenario: You replace a gauge set with a used one, but the mileage on your replacement gauge odometer is too low. Harley will not program a used gauge in my state.
Solution: Use a $25 signal generator off of amazon. Put your bike on a battery charger, Disconnect the speed sensor, and connect the positive lead to the signal wire at the speed sensor harness (female side), connect the negative lead to the ground on the speed sensor harness (female side).
Set the signal generator to square wave, and set the frequency to 22,800 Hz (any higher and my gauge started resetting). Put your ignition to the "ON" and "Run" position. Start your signal generator. You will add mileage to your bike at around 900 mph. I was able to run the generator at 22,800, but no higher than that; photo shows one of my tests at 19,999 Hz
***This is not for mileage "rollback". You can only ADD miles with this method.
