1981 Honda CB750K — Alimentation en carburant

The 1981 CB750K fuel inventory includes one-carb service packages, pump components, holder and airbox-boot sets, control cables and tank fittings. Decide which assembly needs work before buying. Compare the parts currently fitted with each listing so a large package does not obscure a small repair.

1981 Honda CB750K · Fuel system Buying guide

Choose the repair scope before collecting fuel-system parts

A sealing kit, a fuller carb rebuild kit and a pump diaphragm serve different work. Intake rubber sets and a year-listed petcock also have their own requirements; none should be read as a complete fuel-system package.

Do not equate every carb kit with a full repair

The smaller carb service kit lists a bowl gasket, float needle and O-rings. The fuller rebuild kit also names jets and a mixture screw with spring. Both cover one carburetor. Pump diaphragms, tube seals, floats and hardware are separate choices, so use each package’s contents rather than its size or name.

Verify the connections around the chosen part

The petcock listing specifies M18 x 1.0 threads and asks buyers to verify the tank connection. Holder and airbox-boot products each supply four rubbers but specify different clamp requirements. The available pod filters describe another intake arrangement; compare what is actually fitted before making those selections.

Questions before choosing parts

Fuel is not reaching the carburetors. Should I buy rebuild kits first?

Check the supply side first. The original setup uses a fuel-line diaphragm, and Honda identifies blocked vent or vacuum tubes, the diaphragm and its check valve as possible causes of no fuel delivery. An internal carburetor kit will not address those restrictions.

Does a rough idle mean the carburetor jets need replacing?

Not necessarily. Honda’s fault list includes ignition trouble, contaminated fuel, incorrect idle speed and carburetor synchronization as well as carburetor faults. Diagnose these before buying jets; replacing internal parts is not a substitute for finding the cause.

Can a dirty air filter make the mixture rich?

Yes. Honda lists a dirty air cleaner among the causes of a rich mixture, alongside a stuck choke and float-valve problems. Inspect the intake and choke operation before treating rich running as proof that different jets are needed.
