The enrichment pump (or deceleration pump) plays a key role on the Honda ST1100 Pan European: by closing the air passage at idle when the throttle is closed, it temporarily enriches the mixture to avoid detonations and backfires related to a mixture that is too lean. The TOURMAX ACV-110 repair kit allows for the replacement of worn components of this pump to restore smoother engine behavior during deceleration.
Ideal for Pan European owners who are keen on maintaining their roadster, this kit is aimed at riders who want to correct symptoms of a tired pump (irregular idle, stuttering when closing the throttle). Check compatibility with your model before replacement.
