Recaibrating the speedo

[Mykneesbehurtin]

My buddy had a 30 tooth sprocket put on his 09 Tri,everything works as supposed to except the speedo in his opinion seems to be off.My son has the power vision that will do multiple bikes which is what we used to do the down load.So my question is has anyone done the recal of the speedo with the power vision,and if so what is entailed.

Yes, the PV has a place were you can set/adjust the calibration for the Speedometer.

There is a setting in the PV that is used to compute speed (and miles traveled) based on the RPM and gear you are in.

It can be found in your WinPV, under Gear/Speedometer Calibration

I believe the correct value is 2452 for the newer Trikes and 2153 for the two wheel bikes.

Not sure if an 09 with the 30 tooth is the same 2452, but it would be easy enough to check it out and make any adjustments if needed.

I have a 2010 with the 30 tooth sprocket. I used a GPS to compare actual speed after I changed it. Mine came out to 2462. I'll have to recheck it when I have the co-pilot with me to hold the phone.
