The enrichment pump plays a key role in carbureted engines: when the throttle is closed, it restricts the airflow at idle to instantly enrich the air/fuel mixture, thus limiting annoying backfires or flameouts. The TOURMAX repair kit (manufacturer reference: ACV-104) is aimed at motorcyclists who want to address the wear symptoms of the deceleration pump without replacing the entire carburetor.
Compatibility (examples): HONDA CB 400 N (1981), HONDA CX 500 (1979), HONDA CM 400 C CUSTOM (1979). Check the reference suitable for your model before ordering. This kit is aimed at owners of classic roadsters who wish to maintain engine response and clean carburation during deceleration.
