Refurbishing the carburettors, both externally, for cosmetic reasons, and mechanically to replace worn jets, weak springs and the other vital internal parts can be surprisingly cost effective - especially with a new set (if you can find one that is) for some models costing north of 2K Euro.
Vapor blasting the carb body, taking care to ensure no blast medium is left on the inside surfaces, and sonic cleaning the parts that do not need replacement can bring an old carb set back to an almost new condition.
With this in mind, this component and those listed below should help cover the external work to be carried out:
Add as many components as you wish to the same shopping cart, new springs 16053MA6003 (all springs should be renewed as a matter of course) for example, and still only pay the same single fixed price shipping cost. This component may have other, sometimes unrelated applications within the Honda model range, so please always check by the part-number rather than the description prior to ordering.
