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.

Answer QuestionThis 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.
