I have been reading the forum alot but I couldn't find the answers that I need. I am mainly concern about stock and 19T motors. I race the hot bodies cyclone on carpet.

How do I determine what gearing I need? How would I know if I need to gear up or down? How should I gear it differently when it is a RPM motor as compared with a high torque motor?

It seems like the F brush and 767 are the most popular for stock. When you guys say you need to break in the motor, is it just the very first time when you use it, or everytime after you change the brush, or everytime you lathe the motor?

Will it give me better power if I lathe my motor after every run? Or would the motor performs better after a few runs?

lastly, how would the stiffness of the spring affect the performance of the motor? How could you tell if you need a firmer or softer springs?

Currently I am using the monster stock and the KOS27. I am looking to get the MOST out of the motor.........even if I need to sacrifice durability.

Here is some reading material that might help:

Gearing: Find a more experienced racer at the track and ask him for his gearing or "rollout". Copy that until you understand more.

If you switch to a more torque-based motor, use a bigger pinion... but only go up one or two teeth at at time. Use a relatively smaller pinion for a more rpm-based motor.

Brushes: Just use 766 brushes for now... and F brushes later when you need more power.

I think the following links answer most of your remaining questions.

I don't recommend turning your motor on a lathe after every run until you become a much better racer. Clean your motor out well after every 1-2 runs, and turn it on a lathe less often (like every 10 runs?) or so.

Motor maintenance is a funny thing... I think a lot of beginning racers spend too much time trying to get their motors super-fast... but their time at the track would be better-spent talking to their fellow racers, learning, and practicing.

Anyway, Hope it helps. Try hard to read... a lot... before you ask too many more questions. Pretty much everything you want to know is on rctech somewhere.
