ajradrdad Posted September 7, 2010 Share #1 Posted September 7, 2010 I have discovered that my speedometer is off. Someone told me that by changing the rear tire size this will help fix this. Does anyone know if this is true or even possible? Link to comment Share on other sites More sharing options...

Yes, changing the rear tire would fix the speedometer but there's not many options that will fit the RSV/RSTD so you're stuck with using a SpeedoHealer to fix it. Mine was around 8% off if I remember correctly. Link to comment Share on other sites More sharing options...

Mine was around 8% off if I remember correctly. Same story here, approximately 8% on speed, but only 1-2% on the odometer... A SpeedoHealer will correct the speedo, but the odometer will be off...
