Studs and the cylinder head

The kit contains eight studs, eight washers and eight nuts and lists the 1974–78 CB550K. Compare your existing hardware and decide whether the complete kit matches the repair scope. Follow the appropriate Honda service procedure for removal and installation.

Clamp condition matters

The chrome clamp is listed with 14 fins, 55 mm hole centres and Honda references 18231-323-000, 18231-323-010 and 18231-333-010. Compare the installed clamp and pipe mounting arrangement against those details; custom pipes may use different hardware.
