The patented Boyesen QuickShot 3 is the ultimate in adjustable fuel injection for a Keihin FCR carburetor. The QuickShot 3 is a high-performance accelerator pump cover with a built-in adjustable leak jet circuit for simple hand tuning.

A stock accelerator pump cover allows only a 60% - 70% fuel charge in the accelerator pump chamber, while air fills the remaining space. Turning the throttle activates the accelerator pump, but air trapped in the chamber gets compressed, disrupting fuel delivery and often causing a hesitation or bog at the very moment you need immediate response from your engine. The proven Boyesen QuickShot 2 has shown that eliminating trapped air allows for solid fuel delivery 100% of the time, providing the instant acceleration the rider needs.

The adjustable leak jet function of the Boyesen QuickShot 3 allows the duration of the accelerator pump "squirt" to be fine tuned without removing the accelerator pump cover and replacing the leak jet, saving you time and money.  Unlike other adjustable leak jet devices on the market, the QuickShot 3 does not require any drilling or other carburetor modifications.  Just install it, adjust it, and ride!
