About This Product
The Mikuni accelerator pump spring provides the necessary tension required for the consistent operation of the pump plunger within the carburetor body. Over time, heat and repeated use can fatigue the original spring, leading to sluggish throttle response or inconsistent fuel delivery during acceleration. This replacement part is manufactured to the exact spring rate specifications required for Mikuni HSR carburetors. It ensures the pump mechanism returns to its neutral position promptly after every throttle twist. This genuine Mikuni component is sold individually and is a vital part of any comprehensive carburetor service.
Manufacturer part number: TM42/47.
