I'd want to convert my 28 tooth to a 26. NOW, with out saying do a search (which I've already done) how do you correct the 7% increase in speedo and odometer reading?? It's not too big of a concern but if I'm gonna spend $250 on a pulley I want the odo to be correct too. I have a PCIII usb and I do not think there are any provisions to correct it through this. Short of a reflash from a stealer are there any other options... Maybe a Dynojet dealer??
