1977 Honda CB750K · Valvetrain Buying guide

Let the cylinder head inspection define the order

Valves, guides, stem seals and rocker arms perform different jobs in the cylinder head. Separate those requirements before buying, and keep internal primary-chain parts apart from the valvetrain components listed here.

Parts to consider

Separate worn components from sealing pieces

A stem seal is not a replacement valve guide, valve or rocker arm. Ask the person inspecting the cylinder head to identify each required component and any machining before ordering. The intake and exhaust valve listings have separate references, so retain those distinctions when assembling the parts list.

Compare set contents with the gasket package

The individual stem seal is sold each, while the related Kibblewhite Viton set contains eight. Some engine gasket packages already include valve stem seals. Check that coverage first, then choose the needed quantity and material without duplicating components already supplied for the head repair.

Common questions

Are intake and exhaust valves interchangeable in this selection?

They are separate listed replacements: intake reference 14711-300-005 and exhaust reference 14721-300-005. Select the valve for the position identified in the cylinder head inspection rather than substituting one listing for the other.

How many individual stem seals are needed for a CB750?

The individual seal listing states that eight seals are used per CB750 and that seals are sold each. A linked Kibblewhite set supplies eight together. Check whether your chosen gasket kit already contains stem seals.

Are the A and B rocker arms genuine Honda parts?

The current listings describe Japanese-made replacement rocker arms for references 14431-300-030 and 14432-300-030. They should be selected as the stated replacements, with A and B checked against the required position and existing component.
