Boyesen quickshot accelerator pump cover for Yamaha WRF 250 01-13

The Quickshot Boyesen Accelerator Pump Cover allows you to eliminate hesitations and gaps in power delivery, ensuring immediate throttle response.

A normal accelerator pump allows only 60% - 70% of the fuel to enter the pump. The throttle presses gas and air into the chamber, which delays delivery, which in turn reduces throttle response.

With the Boyesen Quickshot Accelerator Pump the pump is completely filled with fuel, delivering fuel instantly, resulting in improved throttle response.

The benefits are as follows:

- Better throttle response;
- Improved performance at low revs;
- Lowering of engine temperature.

The product fits all Keihin FCR carburetors and requires no modification.
