1974 Honda CB360K0 · Exhaust Buying guide
Honda specifies two exhaust-pipe gaskets for the original CB360, one at each port. The single and ten-pack products use the same replacement references, with package size as the practical ordering difference.
A single gasket is useful when one headpipe joint is being addressed; two singles cover both original ports. The ten-pack is a larger stock quantity using the same references. Choose by the immediate job and your need for remaining spares.
Check the headpipe ends and surrounding mounting parts while planning the repair. A changed exhaust may retain the original head joint or use a different arrangement. Confirm the relevant sealing reference and follow the service manual for refitting rather than guessing the tightening procedure.
Honda lists two for the original CB360, one per exhaust port. Order the number needed for the joints being serviced; two individual gaskets cover both original headpipe connections.
Both products replace Honda references 18291-286-000 and 18291-286-306. The ordering difference is one gasket versus a pack of ten.
Compare the joint at the cylinder head and the exhaust manufacturer’s sealing requirements. The original-model gasket reference is useful, but it does not verify an unknown replacement headpipe design.
