Moose Racing 10031439 Overhaul kit for return pumpRef : ME02503A / 10031439

Rebuild Kit Moose Offroad Hard - Parts (manufacturer ref. 46-3001) designed to refurbish the carburettor accelerator pump. When the accelerator pump weakens, the throttle response becomes hesitant and the restarts may lack sharpness; this kit gathers the necessary parts to restore the circuit without having to replace the entire carb.

• Kit contents: diaphragm, spring, all O-rings, necessary screws.
• Type: accelerator pump / accelerator pump.
• Unit: sold as a complete kit.

Simple workshop part to install for professional mechanics or skilled DIYers, this kit targets the classic causes of leaks or loss of sealing in the pump circuit: worn diaphragm, dry seals, or weakened spring. By replacing these components, it limits play and pressure losses that generate slow responses or inconsistent acceleration.

Suitable for Enduro and Cross environments, this kit is particularly suited for lightweight high-rev machines where carburettor responsiveness is crucial. Examples of affected models: HONDA CRF 150 R (KE03), HONDA CRF 250 R (ME10), HONDA CRF 150 RB (KE03). Manufacturer reference: 46-3001.
