It does but he is measuring out form the center of the crank so it is the same distance (radius) on both flywheels. For example if the measurement for drilling was 9" from center of the flywheel on the 130 tooth wheel and he used the same 9" from center on the 143 tooth wheel they should be the same balance as long as anything outside of that 9" dimesion is neutral. In other words he is removing the same amount of material in the same spot on the flywheel as measured from the center, but the measurement would be a larger number on the 143 wheel if measured from the outer diameter.
