1983 Honda CB750SC Petcocks & Tank Caps

Identify the tank component needing repair before ordering for the 1983 CB750SC. The threaded petcock, filler cap and automatic shut-off valve are separate items. Compare the tank actually on the motorcycle, especially after replacement, and keep cap contents distinct from a valve-sealing package.

1983 Honda CB750SC · Petcocks & Tank Caps Buying guide

Choose the fitting at the source of the fault

The petcock uses M20 × 1.0 threads, while the cap supplies a gasket and two keys. The automatic shut-off repair kit is for a separate assembly, so locate the fault before selecting a tank-service package.

Check tank changes before ordering fittings

The stated M20 × 1.0 petcock thread must match the actual tank. Also compare the outlet and hose route, and check the cap opening separately. A replacement tank can alter those fittings without changing the motorcycle’s model identity or engine application.

Respect the shut-off assembly’s contents

The automatic-valve repair kit contains sealing pieces for its specific assembly. One included O-ring may not be used in every configuration. Match the fitted valve and service instructions rather than forcing an additional seal into the assembly to use every supplied piece.

Petcocks & Tank Caps questions

Does the cap come with its own keys?

Yes. The cap includes a gasket and two keys. Compare the tank opening and locking style before ordering, especially if the original tank or filler assembly has been changed.

Will the M20 petcock fit any tank on this bike?

Only after checking the actual thread and clearance. A changed tank may use a different petcock fitting, so the motorcycle’s year alone cannot establish compatibility.

Must every seal from the shut-off kit be installed?

The product notes that one O-ring may not be required in some configurations. Identify the fitted valve and follow its repair information to determine which supplied pieces apply.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
