1972 Honda CB350K4 · Exhaust Gaskets Buying guide

Count seals separately from the surrounding hardware

A cylinder-head exhaust gasket seals one port. The retaining collars and mounting pieces perform other jobs, so assess them independently instead of treating the gasket package as a complete mounting kit.

Parts to consider

Keep individual and bulk quantities clear

One individual product supplies one gasket. The related ten-pack supplies ten of the same service type, rather than paired motorcycle sets. Decide how many ports are being renewed now and whether keeping additional gaskets is useful for your workshop before choosing the pack.

Prepare more than the sealing rings

Honda’s K4 exhaust diagram distinguishes the port gaskets from the split joint collars. Check that the retained collars, flanges and fasteners are usable and present. Inspect the linked stopper rubber separately, using the contact arrangement on your actual exhaust as the guide.

Buying questions

Will one individual gasket reseal both sides?

No. One gasket serves one exhaust port, and Honda specifies two for the K4 twin. Buy the number required for the ports opened during the repair.

Are the split collars supplied with the gaskets?

The products are described as exhaust-port gaskets, individually or in a ten-pack. Do not assume collars or mounting fasteners are included; inspect and source those components separately as needed.

Why check the stopper before refitting the exhaust?

Its condition and contact position are easier to assess while planning the pipe work. If the exhaust or stand arrangement has changed, confirm where the stand stops before selecting the related replacement rubber.

Not sure which part you need?

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