For me, as long as temperatures are within an acceptable range, the gearing is fine. The best thing to do is just experiment. Start with the smallest pinion gear that you can and go up from there, checking temperatures every few minutes. Also Speed = Motor RPM*(tire circumfrence)/(88*Final Drive ratio). So at least get a pinion gear that is large enough for reasonable speeds.
