speedohealer calculation question
for anyone who owns a speeohealer, when you are doing the calculation, where it says "tyre of speedo driving wheel" and then has the "from" and "to" sections, do you just put in the size of your front then rear tire? how does it work? also, how do you know whether or not to make it calculate for factory speedo error? thanks

From should be stock size, to the new size, even if it's the same is what SH told me. That seemed to iffy to me, so I unplugged mine, found a speedsign (the big boxes the cops have the show your speed?) and went through it at indicated 60 for my actual speed.
Then, follow the instructions for a reset to factory values and plugged in the indicated/actual values for a more precise fixing.

I used my handheld GPS and noted what my speedometer read when the GPS showed 60mph and 80mph then corrected based on that. With factory error and different sprockets my speedometer was off by over 10%. It is dead on now.
