Unconditionally guaranteed or your money back. See how to easily obtain a 25 % increase in fuel delivery on a Keihin FCR carburetor by installing a Boyesen Quick Shot 2 accelerator pump cover . In this video I test the claimed 25% increase in fuel capacity and compare spray patterns for volume and distance . The bike is also tested at a local race track to see if I could notice any significant change in performance compared to the stock accelerator pump cover . There were no other modifications on the carburetor so as to keep the findings as accurate as possible .Although it is important to remember that to achieve maximum performance on any carburetor , fine tuning and jetting adjustments are typically required .
I have no affiliations with Boyesen and am not sponsored in any way .
