Accelerator Pump Rebuild Kits

Restore Throttle Response with Our Accelerator Pump Rebuild Kits

When your bike, ATV, or dirt‑bike starts hesitating, sputtering, or bogging down the moment you twist the throttle, the culprit is often a worn-out accelerator pump. Modern fuels—especially ethanol blends—can quickly degrade diaphragms, springs, O‑rings, and cups, leading to poor fuel delivery and sluggish throttle response
