Frequently Asked Questions

Is Honda OEM 90541-422-000 the complete perimeter cam-cover gasket?

No. It is the rubber sealing mount used at a cam or valve-cover fastener. The large perimeter cover gasket is a separate part.

How many 90541-422-000 cam-cover seals are included and required?

One seal is included. Eight are used per listed 1979 CB750K, CB750F, CB900F or CB650, so eight are required to renew every fastener seal on one engine.
