Sure, give me your compensator sprocket, clucth basket spocket, tranmission sprocket, rear sprocket tooth count, 5th or 6th gear final ratio, and the diameter of your rear tire and I'll let ya know.

Not to mention: are you going a steady speed, or ramping up or down?

compensator sprocket, 25
clutch basket spocket, 36
transmission sprocket, 32
rear sprocket, 70
5th gear final ratio, 3.15
diameter of your rear tire, 25.71 (MU85)
50mph=2059
60mph=2471

Rpm-mph

This should help. The only variables you need to mess with are gear ratios and rear tire diameter/radius.
