Unique 4-Sided design offers a power gain at all RPM ranges.

Install the Pyramid Reed Valve and your engine will have better throttle response, stronger midrange and increased top end power.

Why does the Pyramid work so well?
Side pedals distinctive to this design open easy at low RPM's giving engine better throttle response and more low end power. As RPM's climb through the powerband, reed pedals on all 4 sides open giving the engine MAXIMUM flow making better power in the mid and high RPM's.
