Default Motor change generalities

I have the Tower Hobbies "Cutback" (4wd SC). I want to change the Motor. Current(Factory) motor is a 3600kv,4 pole with a 11t pinion and 64t spur gear. Would like to go to a 5400kv, and keep the same spur gear. What should I change the pinion gear to so I don't fry the motor??....AGAIN.

Something doesn't seem right. An 11t pinion and a 64t spur is a relatively high ratio, especially for a 4 pole motor. Sounds way undergeared.

Correction, the spur gear is 62T (32 pitch) center diff on a 4wd. This is out of the box gearing on this truck.
