Stock accelerator pump covers permit only a 60% - 70% fuel charge in the pump chamber. Turn the throttle and air in the chamber is compressed and fuel is delayed. The result: Hesitation or Bog. The Boyesen Quickshot cover completely fills the pump chamber with fuel, and provides instant fuel delivery, eliminating the hesitation and bog.

Questions & Answers
Will this fit the 2023 Crf150R?
By Dylan C.
Yes! If you were to choose the 2023 Honda CRF150R Quickshot from our fit guide, you'd receive the correct part to fit your machine's carburetor.
Is the diaphragm included
By Anon.
This kit will not include any gaskets, diaphragms or O-rings only the accelerator pump cover. The mounting surfaces are identical to the stock Keihin FCR carburetor. You would reuse the original O-ring, diaphragm and spring when installing this Boyesen Quickshot 2.
