thats the ratio, 13:1 basicly means it takes 13 revolutions of your motor to cycle the piston once. look for something in the 18:1 to 22:1 ratio. Modify highspeed gears are about that. as are king arms torque gears. the lower the first number the higher rate of fire, the higer they are lets you pull heavier springs.
the easiest most pain free way of doing your gearset is the modify smooth series, they are pre shimed, come with the bushings, and anti-reversal latch. they only need to be droped in and away you go, definately worth the 100$ price tag. especially if you have no idea what you are doing with the insides of a gearbox. you will probly need a 6mm set for your gearbox.
