1983 Honda CB750SC · Valves & Stem Seals Buying guide

Order head parts by inspected position and condition

Replacement valves are individual parts, with different references for intake and exhaust. Stem-seal quantities are separate: the individual seal application uses 16 per motorcycle, while the Kibblewhite alternative is a 16-piece package.

Avoid treating every valve as the same part

The intake and exhaust replacements have different references and are sold individually. Keep their positions identified during the head assessment. Replacing a valve does not establish that its guide or seat is serviceable, so agree the complete repair with the person rebuilding the head.

Choose seal quantities around the actual order

The individual valve stem seal is sold each, with 16 used per bike. A related Kibblewhite Viton set supplies 16 in one package. Check whether your larger gasket order already contains seals before deciding which sales format makes sense.

Valves & Stem Seals questions

What should I establish before ordering valves?

Have the head inspected to identify the intake or exhaust positions needing work. Match the required references and count individual replacements, with guide and seat work assessed before assembly.

Does buying sixteen individual seals equal one full set?

The application specifies 16 seals per motorcycle. The alternative Kibblewhite package also contains 16. Choose the appropriate product and avoid duplicating seals already included in a gasket kit.

How many individual valves should I buy?

Use the head inspection to identify which positions need replacement. The valves are sold individually, so build the order from those findings rather than assuming every valve needs renewal.

Not sure which part you need?

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