1994 Honda CB1000 · Valvetrain Buying guide

Sixteen small seals

Worn stem seals let oil run down the guides, which shows as blue smoke on start-up. They can only be replaced with the valves out, so they suit a head rebuild.

Fit them during head work

Stem seals are hidden under the valve springs, so the head has to be stripped to reach them. If you already have the head off for a valve job or a gasket change, renewing all sixteen adds little time and removes one cause of oil burning.

Ordering

The seal title names the CB750, CB900 and CB1100, but the fitment block also lists the CB1000 of 1994-95. Order the quantity your job needs, since each seal is priced singly, and keep a spare in case one tears.

Valvetrain questions

How many stem seals are used?

Sixteen per engine, one for each valve, according to the listing. Each seal is priced as a single unit, so add the full count to your order if you are renewing them all.

Is a sixteen-seal set listed?

A set of sixteen is tagged to this bike but is archived, so it cannot be ordered. The single seal is the published option, so order sixteen of those.

Are shims or valves listed?

Not for this model right now. The stem seal is the only valvetrain part published for the 1994 CB1000, so shims, valves and springs would need another source.

Not sure which part you need?

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