The valve or guillotine open as you throttle up and are restricted by a spring and bellows under the red portion of the cap. You can take a small flat blade screwdriver and turn or unscrew the red portion. bring the top of the red cap out flush with the top of the black cap. This will allow the valve to open sooner, thus increasing the opening of the exhaust port and developing more power.
