Product Description

The patented Boyesen Quickshot 3 adjustable accelerator pump cover packs a ton of technology into a small package.  The Quick shot 3 is a "True" adjustable accelerator pump with an adjustable leak circuit.  It allows you adjust the volume of fuel that is injected into the venturi in order to provide a "perfect" pump squirt.  With the constant on/off/on throttle chopping on Motocross bikes, the Quick shot pump allows a volume to be dialed in that won't flood the engine with excess fuel.  Works with ALL Keihin FCR and FCR-MX carburetors including OEM style FCR carburetors.


The design also provides an anti-cavitation fuel chamber that has been proven to eliminate any air pockets thereby allowing the diaphragm to work at maximum efficiency.  This all combines to provide superior throttle response over non-adjustable pumps.  The Boyesen Quickshot pumps offer the following features:
  • Maximizes volume and duration of fuel squirt for all conditions
  • Cast and machined to precise tolerances
  • Offers 25% more fuel capacity
  • High volume check valve for precise, consistent metering
  • Offers instant throttle response while eliminating bogging
  • Improved low end performance
  • Fits ALL Keihin FCR carburetors including the OEM models
  • Simple bolt on installation

Replacement parts are available, please inquire.  In addition stronger pump springs are also available to solidly actuate the pump and prevent hydraulic lag.  They do not crack, harden, and break like o-rings do.
