1971 Honda CB750K · Valvetrain Buying guide

Order around the cylinder head inspection

Valve, guide, rocker and sealing needs are different buying decisions. Use the findings from the head inspection to choose individual replacements or sets, without assuming every item requires replacement.

Separate inspection results from catalog options

The category includes ordinary replacement valves and performance head components. Availability does not establish which parts your head needs. Have the valves, guides and associated components assessed, then compare the required replacements with the product details and the service specifications used by the person doing the work.

Check the form in which a part is sold

The ordinary valve stem seal is an individual item, while the Kibblewhite seal listing supplies eight. Rocker arms A and B are separate replacement listings with different references. A head order should account for those distinctions rather than treating a pair, a single part and a set as interchangeable.

Common questions

Does the individual valve stem seal fit intake and exhaust guides?

The listing states that it serves both intake and exhaust valve guides on 1969–78 CB750 models. It is sold individually and specifies eight seals per CB750. Order the quantity required after checking the contents of any gasket set.

How do I identify rocker arm A versus rocker arm B?

Rocker A references 14431-300-030; rocker B references 14432-300-030. Identify the required position and reference before ordering either Japanese-made replacement arm.

Could my gasket set already include the valve stem seals?

Check the sealing package contents before adding individual seals or the eight-piece Kibblewhite set. The Athena top-end package in the engine gasket range includes valve stem seals, so combining both can duplicate that part of the order.

Not sure which part you need?

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