Stock accelerator pump covers permit only a 60% - 70% fuel charge in the pump chamber. Turn the throttle and air trapped in the chamber is compressed disrupting fuel delivery. All the while tuning the squirt means a complicated change of the leak jet.
The Result:
Hesitation, bog and a tuning headache.
The Patented Boyesen QuickShot 3's triple effect: (1) Completely fills the pump chamber with fuel (2) Eliminates troublesome air and (3) Provides an adjustable leak jet circuit for simple hand tuning.
The Result:
The ultimate in adjustable fuel injection.
