Tokyomods Accelerator Pump Spring
The new Tokyomods FCR carburetor accelerator pump spring will increase throttle response and horsepower on all Bikes and quads using an FCR carburetor. This new spring will also alleviate the stubborn bogging problems common with many FCR carbureted Bikes and ATVs. The new Tokyomods spring is designed for the maximum fuel squirt and the optimal squirt duration. Other aftermarket springs are far too stiff; much like wiring your accelerator pump together it shortens the squirt duration and in some cases it can also lead to severe accelerator pump binding problems.
