1973 Honda CB750K · Valvetrain Parts Buying guide

Identify each cylinder-head component separately

A cylinder-head repair can involve several small parts, but they are sold under distinct listings. Compare the valve function, rocker-arm reference and seal quantity instead of building the order around a general rebuild label.

Parts to consider

Keep intake and exhaust choices clear

Keep intake reference 14711-300-005 separate from exhaust reference 14721-300-005. If valve guides are also being replaced, identify their design: the offered standard-size Kibblewhite guides are shoulder-style parts and do not use separate OEM-style clips.

Order rocker arms by the listed identity

Rocker arm A references 14431-300-030; rocker arm B references 14432-300-030. Compare the removed component and repair plan with those identities. Neither the letter nor a shared CB750 application establishes the number required for the work.

Common questions

Do the Kibblewhite guides need separate valve-guide clips?

The offered standard-size Kibblewhite intake and exhaust guides are shoulder-style guides that do not use separate OEM-style clips. Identify the guide design before adding clip reference 12211-250-310 to the order.

Does one valve stem seal order cover the cylinder head?

The stem seal is sold individually and fits the listed intake and exhaust guides. Its CB750 application specifies eight seals per bike. Order the repair quantity, or check whether your selected gasket set already supplies them.

How do I choose rocker arm A or B?

Use the separate references: A is 14431-300-030 and B is 14432-300-030. Match the removed rocker and its location before ordering rather than choosing from the motorcycle year alone.
