retiming a motor is basically turning the brushes a few degrees from centered over the magnets. this is used alot in rc car racing. "modified" motors. stocks are i think advanced 24 degrees. you never want to retard the timing so this is good for applications for forward only. like rc car racing. but unless you want to make a reverse gear transmission, its bad for the motor, as going backwards in an advanced motor=going forward in a retarded motor. depends on how you look at it.
basically its just like the timing of a car. you can time it so its strong at different points of the curve, but if you overdo it the motor doesnt work or wears down REAL fast. here, the brushes and the comm.
