you can increase or decrease the number of teeth on ur front or rear sprocket to alter the bikers performance, many people add a couple of teeth on the rear or decrease on the front to improve acceleration and decrease the rear or increase front to improve top end.
however as already said when u replace a chain u should change them as the chain causes specific shapinf of the teeth
