1977 Honda CB750K · Fuel System Buying guide
A carburetor rebuild, intake-rubber replacement and tank repair require different parts. The 1977 listings specify one-carb kits, a four-piece holder set and a threaded petcock; count each package according to the repair rather than treating one item as coverage for the whole fuel system.
1977 one-carb rebuild kitJapanese-made kit for one carburetor, with a #115 main jet, D432 slide needle, float needle, bowl and top gaskets, six O-rings and the listed adjustment parts.View part

The holder set names four clamps of type 15-0685 for one side and four of type 15-0688 for the other. The individual airbox boot uses different listed clamps. Compare the fitted connections and each rubber listing before assuming one clamp package covers the whole intake.
The petcock thread belongs to the tank, while carb holders and airbox boots must suit the installed carburetors. A replacement tank or different carb bank can change those checks. Keep the original parts nearby for comparison rather than relying on the motorcycle year alone.
The packing kit lists bowl and top gaskets, O-rings and a needle. The larger 1977 kit adds a named #115 main jet, D432 slide needle and other adjustment parts. Compare the damaged pieces with both contents lists; each package services one carburetor.
The 1977 rebuild kit contents do not list an accelerator-pump diaphragm. That component has its own linked listing with a diaphragm, rod and bellow rubber. Check the pump separately if it is part of your repair.
The genuine Honda lid is 17531-405-000ZB in Excel Black. Its listing distinguishes color suffixes such as ZA and ZB and excludes the latch, lock, hinge hardware, seal and molding. Compare the original part number, finish and reusable fittings before ordering the cover.
