Why Your Accelerator Pump Wears Out
The accelerator pump diaphragm hardens and cracks over time from heat, fuel exposure, and age, especially on bikes that sit between rides. Once it loses flexibility, the pump can't deliver its fuel shot properly, causing that frustrating bog or hesitation when you snap the throttle open out of a corner. A worn diaphragm is one of the most overlooked reasons for poor throttle response on an otherwise healthy engine.
