Boyesen Accelerator Pump Cover

The Boyesen Accelerator Pump Cover is an example of their innovation.  Stock accelerator pump covers allow only 60% - 70% fuel charge in the accelerator chamber.  Turn the throttle, and the air in the chamber is compressed & fuel delivery is dalayed, resulting in hesitation or bog.  The Boyesen QuickShot cover completely fills the pump chamber with fuel & provides instant fuel delivery, eliminating hesitation & bog.
