1971 Honda CB450K · Carb Floats & Other Carb Components Buying guide

Identify the component by its location and contents

A float-and-pin assembly is different from the float-valve needle and seat. A bowl drain screw is another fitting with its own seal. Both products here are sold each, so their purchase counts follow the parts being renewed rather than the scope of a carburetor kit.

Parts to consider

Honda CB Stock Type Float Bowl Drain Screw Sealed float-bowl drain screwThe written contents specify a drain screw with O-ring, sold each. Compare the retained bowl, screw and seal arrangement. No thread dimensions are given for assessing a bowl fitted during earlier modifications.View part Honda CB Carb Float ~ Replaces 16013-283-004 Carburetor float including pinFloat-and-pin replacement referencing Honda 16013-283-004. Sold individually; count the floats being renewed. Compare the installed assembly and keep this purchase separate from the needle-and-seat valve components.View part

Check the float repair alongside the chosen kit

The premium rebuild kit includes float needle and seat components but does not list a replacement float. The separate float names its pin as included. Read the parts required by the actual repair before adding a float, a valve set or both to a kit purchase.

Use the installed bowl to resolve the drain fitting

No thread diameter, pitch or complete sealing-seat dimensions are stated for the drain screw. Compare the retained bowl and removed screw, especially if the carburetor or bowl was replaced. Confirm missing measurements needed for that assembly instead of choosing from the stock-type name alone.

Questions to help choose the repair parts

Is the float pin listed with the replacement float?

The float description explicitly names a float with pin, sold each. Check that assembly against the retained carburetor and order the number being renewed. A separate valve set describes a needle and seat rather than the float-pin assembly.

What if the bowl drain thread cannot be identified?

Establish the thread and seal arrangement in the bowl before ordering the replacement screw. Its description does not give those dimensions. Confirm the missing specification when a changed bowl cannot be matched from the existing fitting.

Should I add a replacement float to a rebuild-kit order?

The premium kit lists a float needle and seat but does not list a replacement float. The separate float includes its pin and is sold individually. Inspect the existing float and compare kit contents before adding the parts needed for that carburetor.
