Is it possible to increase the torque of the stock motor? If so, how?

One quick and cheap way to increase the torque of your stock motor is to replace

the stock motor springs (the springs that hold the brushes up against the

commutator). Harder springs produce more tension and more amp draw, thus

resulting in more torque but less RPM. On the other hand, if you want less torque

but more RPM, a pair of softer spring is the way to go. Take the motor to a local

electronic shop and find springs that work for you. Do keep in mind that very

hard springs are no good as they impose too much pressure on the commutator.

Very soft springs are no good as well, since they allow the brushes to bounce on

the commutator. Some trial and error may be necessary to get this done

properly.
