Any way to calibrate speedometer?

I am showing about 120 MPH when doing about 40 MPH in my setup. Anyway to have this calibrated?

Polaris RZR with an '04 SP2 transplanted in it. Chain driven through a gear box with axles and CVs. The only thing left stock on the RZR is the frame and plastics . But, the frame is beef'd up too .

The only way to compensate for final sprocket ratios is to buy an Speedo-Healer.
It interconnects between the speed sensor (at the rear of the engine) and the Speedo Gauge/ECU.
You can then configure the final drive ratio and rear tire diameter
Or you can calibrate via GPS.

Yep, and at that point, get yourself a gear indicator! I have a speedo healer on all my bikes, but no indicator!
