1971 Honda CL350K3 · Exhaust Gaskets Buying guide

Match each serviced joint to the correct gasket

The single-piece option lets you order an exact count. The ten-pack provides additional gasket stock. Both share the stated references, so application confirmation comes before the package-size decision.

Parts to consider

Use references to compare the sealing part

Both options cite 18291-286-000 and 18291-286-306. Compare those references with the fitted engine and exhaust information, particularly where pipes have been changed. The shared numbers describe the offered replacements; they do not document every modification that may have been made to the motorcycle.

Make a separate mounting-hardware list

Check collars and fasteners during the same inspection as the sealing joints. Order replacements only where their condition calls for them, and identify any aftermarket pipe hardware separately. Follow the service procedure appropriate to the fitted exhaust when assembling the joint.

Buying questions

Do the single gasket and ten-pack have the same replacement references?

Yes. Both specify 18291-286-000 and 18291-286-306. Choose the quantity for your planned work after confirming the fitted exhaust’s gasket requirement.

How many gaskets does the individual item supply?

One order quantity supplies one gasket. Count the joints included in your repair and use that count when buying individual pieces; do not interpret the item as a multi-gasket set.

What if the removed gasket no longer has a useful shape?

Compare the replacement references with the engine and exhaust parts information. If the pipes are aftermarket, obtain their gasket specification rather than using a distorted old gasket as the only guide.

Not sure which part you need?

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