1977 Honda CB550K · Carb Floats & Other Carb Components Buying guide

Separate float, screw and seal requirements

The float and drain pieces have different supplied contents. Compare the carburetor and the removed component before choosing a complete float, an individual drain screw or a seal-only pack for the work.

Check the float purchase separately from the needle

The float listing supplies a float and pin and identifies four floats per bike. Choose the quantity needed for the assessed work. That contents statement does not name a float needle; identify any additional needle requirement separately instead of treating the float and pin as a complete inlet-valve package.

Choose a screw-and-seal or seal-only purchase

The individual drain screw comes with an O-ring, while the separate drain-seal pack contains four O-rings. Compare the condition and identity of the required parts before combining these products. The air-screw needle O-ring is separately named for another position, not a substitute chosen simply because it is small.

Common ordering questions

Does the replacement float come with its pin?

Yes. The float description expressly says it includes a pin and lists the replacement references. Compare the fitted float and carburetor with that information, then order the quantity needed for the planned work.

Do I need a separate seal for every new drain screw?

The individually listed stock-type drain screw already names an O-ring in its contents. Compare that supplied screw-and-seal product with the four-pack of seals before adding both purchases for the same drain positions.

Can I choose the felt shaft seals by motorcycle year alone?

The felt-seal listing is conditional on compatible Keihin PD carburetors. Identify the carburetors actually fitted before choosing those seals; the motorcycle year alone does not establish that the required throttle-shaft application is present.
