1980 Honda CB750K · Valvetrain Parts Buying guide

Choose shims from the measured valve requirements

Use the shim assortment for a range of specified sizes or individual shims for a known requirement. Replacement valves and stem seals are separate choices for cylinder-head repair.

Read the assortment before choosing it

The 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. A twenty-piece assortment does not mean twenty different sizes.

Keep seals separate from the valves

The individual valve stem seal replaces reference 12209-422-005. It is a separate item from the intake and exhaust valves; check any gasket-set contents before adding it to a larger order.

Common questions

Can I buy extra 2.70 shims without another kit?

Yes. The separate 2.70 shim is 25 mm in diameter and sold each. That lets you add pieces beyond the two supplied in the assortment.

Does a valve order include both intake and exhaust parts?

No. The intake and exhaust valves have separate listings and are each sold individually. Keep their different references on the order.

Should I add separate stem seals to an overhaul gasket set?

Check its contents first. The Athena overhaul set lists sixteen stem seals; separate seals would duplicate that portion of the package unless you need additional pieces.

Not sure which part you need?

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