The TOURMAX enrichment pump repair kit (ref. ACV-201) is designed to restore the functioning of the deceleration pump on the relevant Yamaha machines. The enrichment pump closes the air passage at idle and instantly enriches the mixture when the throttle is closed, thereby limiting detonations and backfires related to a mixture that is too lean.
This kit is aimed at motorcyclists and quad owners who want to restore the carburetion system related to deceleration. It is particularly suitable for the Yamaha models listed below; however, be sure to check the exact compatibility with your vehicle before proceeding.
