1974 Honda CB360K0 · Exhaust Port Gaskets Buying guide

Count the headpipe seals before choosing a pack

The individual gasket and ten-pack share the same Honda replacement references. Decide how many original headpipe joints will be opened, then select the package quantity without assuming a ten-pack is a bike-specific kit.

Use singles for a focused repair

Each single product supplies one exhaust-port gasket. Honda’s original CB360 arrangement uses one at each of two ports. Count the joints involved in the work before ordering, and compare the fitted headpipe joint when an aftermarket exhaust is present.

Understand the larger pack

The ten-pack supplies ten of the listed port gaskets rather than a mixed mounting kit. It suits repeated exhaust service or a shared parts shelf. Both pack options use references 18291-286-000 and 18291-286-306, so quantity drives the choice for an original joint.

Buying questions

Do I need a ten-pack to service both sides?

No. Two individual gaskets cover the original pair of headpipe ports. Choose the ten-pack when its additional spare gaskets are useful for your planned work.

How many complete original bikes does a ten-pack cover?

At two port gaskets per original CB360, ten gaskets provide five complete pairs. That is a quantity calculation, not a requirement to replace unrelated exhaust hardware.

Can I select these for a modified exhaust by model alone?

Check the sealing joint and the exhaust maker’s requirements first. These references match the original CB360 port-gasket application; a changed headpipe may need a different sealing arrangement.

Not sure which part you need?

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