1982 Honda CB900F Supersport · Carburetor Components Buying guide
Locate the fault before choosing a float, pump diaphragm or sealing pack. The float needle controls fuel entry, the accelerator pump enriches throttle opening, and drain and connector O-rings seal different joints on the CB900F carburetor bank.

Honda’s 1982 supplement shows the slow jet beneath a plug, separate from the primary and secondary main jets. Match the installed plug and carburetor construction to the replacement listing. Five plugs in a package does not establish a universal count for every rack.
The linked drain screw includes its own O-ring. A seal-only repair can use the separate drain O-rings if the screw and bowl seat are sound. Connector-tube O-rings seal between carburetors and require enough rack separation to remove the tubes; they are a different repair.
No. Check that the float moves freely and inspect the float needle, its seat and the fuel inlet for debris or damage. Verify the correct float level for the installed carburetor. A new float cannot repair a damaged needle seat.
Trace the leak to its joint. Drain seals fit the individual bowl drain screws; connector seals fit tubes between the carburetors. Inspect the screw tip, groove and bowl seat before buying seals alone, and plan rack separation for connector-tube work.
The 1982 Honda diagram places a plug over the slow-jet passage. Check that the correct plug is present and sound and that the passage is clean. Match the actual carburetor version; a five-piece replacement pack does not define every rack’s usage count.
