Gear Up --

Refers to changing out the pinion or clutchbell, or spur gear, to increase top speed at the expense of acceleration and torque. Gearing up is accomplished by either installing a pinion or clutchbell with more teeth (i.e. changing an 17T pinion to a 18T pinion) or installing a spur gear with fewer teeth (i.e. changing a 74T spur to a 72T spur). Note that pinion or clutchbell changes can be made 1T (tooth) at a time for subtle changes, while spur gears can only be changed by 2T at a time, for more dramatic results. Gearing up decreases run time.
