I race on a small dirt off road track, with a losi mf2 13.5 novak brushless motor, what does changing the spur and pinion really do? I know it changes the ratio. Im talking about speed and torque.

A bigger pinion = higher top speed. smaller pinion = more torque

A smaller spur = higher top speed. a bigger spur = more torque
