Frequently Asked Questions

How many Nighthawk carburetor floats are included and required?

One carburetor float with its pivot pin is included. The listed CB550SC, CB650SC and CB700SC Nighthawk four-cylinder models use four carburetors and one float per carburetor, so four floats are required to replace all of them.

Does carb float 07-4650 include the float valve needle, seat or bowl gasket?

No. Part 07-4650 includes one float and one pivot pin. The float-valve needle and seat, carburetor bowl gasket and other rebuild components are separate parts.

Does Honda float number 16013-KR3-980 replace 16013-MA6-003?

Yes. Honda reference 16013-KR3-980 supersedes 16013-MA6-003, so either number can appear in an original parts fiche or on old packaging for the compatible Nighthawk carburetors.
