The TOURMAX enrichment pump repair kit (ref. ACV-109) restores the deceleration pump of Honda carburetors. When the throttle is closed, this pump temporarily shuts off the air intake at idle and enriches the mixture to prevent knocking and backfiring: a discreet yet crucial element for clean deceleration and safe engine operation.
Designed for riders who are keen on maintaining their carburetors, this kit helps avoid symptoms of a worn pump (weakness during deceleration, knocking, smoke, or misfires). It is aimed at owners of Honda models equipped with this system, including the PC 800 Pacific Coast (RC34), the VT 600 C Shadow (PC21), and the NT 650 Hawk GT (RC31).
Easy to install for those familiar with carburetor disassembly, this TOURMAX kit offers a targeted refurbishment solution without the need to replace the entire carburetor. Ideal for keeping your machine healthy and safe on the road.
