I just recently replaced the stock 25" tires with 26" Vampires. Is there any way to recalibrate the odometer myself so that the correct speed is displayed ? Or is this a dealer issue. If a dealer issue, I'll probally just live with it as it is only off 2 or 3.

 

mine was off 3mph form the factory and putting 26's on it make it accurate now[img]i/expressions/face-icon-small-wink.gif[/img]

 

ATV speedometers aren't very accurate to begin with. I don't believe they can be calibrated either. If you want an accurate speed reading, invest in a GPS unit.
