“The ultimate in adjustable fuel injection 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. Currently available for ALL Keihin FCR carbureted MX, Offroad and ATV models. This patented 3rd generation QuickShot features an innovative triple effect that: 1 - Completely fills the pump chamber with fuel, 2 - Eliminates all trapped air from the system and 3 - Provides an adjustable leak jet circuit for quick hand tuning. Together with the Boyesen unconditional guarantee, the QS3 simply delivers unmatched results.
