Frequently Asked Questions

How many Honda oil stopper caps 12242-425-000 are included and required?

One oil stopper cap replacing Honda OEM 12242-425-000 is included. The listed DOHC Honda CB cylinder head uses two stopper caps, so two are required to replace both.

Where does oil stopper cap 12242-425-000 belong?

It seals a cylinder-head oil passage on the compatible Honda DOHC engine; it is not an external oil-filler cap. Confirm the location in the cylinder-head parts diagram before installation.

What should be inspected when replacing the oil stopper caps?

Clean the bores without scratching the sealing surfaces and inspect the surrounding area for hardened rubber, damage or the true source of an oil leak. Install to Honda service-manual depth and orientation.
