here is the original thread: resetting speedometer

so what is the formula for getting everything back to stock? output drive gear, speed-o gear, r&p, tire diameter - i guess all this needs to be known from the original set up to try and match their relation to one another.

how many different sized drive gears(output shaft) are there? just thinking that if required more substantial change than 1 tooth(speed-o gear) and ever doing/planning terra 3:1 gear change then the perfect combo can possibly be had and that would be the opportune time to do it.
