1980 Honda CB750C · Valvetrain Parts Buying guide

Separate clearance adjustment from head rebuilding

Shims are selected from measurements. Valves and seals are selected for the head components being renewed; an assortment of shims is not a cylinder-head overhaul package.

Parts to consider

A shim kit offers a range

The twenty-piece kit contains two each of 2.30, 2.40, 2.50, 2.55, 2.60, 2.70, 2.80, 2.90, 3.00 and 3.10 sizes. All are 25mm diameter. Compare your calculated requirements with that range before buying the assortment.

Head parts are position-specific

The intake valve and exhaust valve use different references. The standard valve stem seal is sold individually, with sixteen used across the motorcycle. Let the head inspection determine what needs replacement and use the service manual for the work.

Valvetrain Parts questions

Does the shim kit include every available thickness?

No. It includes two of each of ten named sizes. Individual shims are also available in additional listed thicknesses, so compare your measurements with the actual kit contents.

What should I establish before ordering replacement valves?

Have the head inspected to identify the intake or exhaust positions needing work. Compare the required valve references and count individual replacements rather than assuming every valve needs renewal.

Is one valve stem seal a complete set?

No. The standard seal is sold individually and sixteen seals are used per motorcycle. Order the quantity your head work requires, taking any included gasket-set seals into account.

Not sure which part you need?

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