1971 Honda CL350K3 Exhaust Service Parts

Exhaust work does not always require a complete replacement system. The current 1971 Honda CL350K3 selection is focused on headpipe-port gaskets, available individually or in a ten-pack, so match the fitted exhaust and buy for the service you actually plan.

1971 Honda CL350K3 · Exhaust Buying guide

Choose gasket quantity around the exhaust job

The two products offer different package quantities with the same stated replacement references. Choose individual pieces for a defined repair or the ten-pack when its additional supply suits planned workshop use.

Parts to consider

Keep package size separate from repair quantity

One product supplies one gasket and the other supplies ten. Decide how many are needed for the planned work before choosing between them. A larger pack is a supply choice, not an indication that ten gaskets are required during a single motorcycle service.

Inspect the exhaust before blaming the gasket

A damaged mating surface or an altered pipe arrangement can affect what the repair needs. Have the joint inspected and compare the offered gasket references with the installed setup. Follow the applicable service instructions for fitting rather than trying to overcome an unresolved problem with extra gasket material.

Buying questions

Is the ten-pack a different gasket specification?

Both products cite replacement references 18291-286-000 and 18291-286-306. The stated difference is package quantity: one piece or ten. Confirm the fitted exhaust application before choosing the supply amount.

Can these gaskets be assumed to suit custom headpipes?

Check the pipe maker’s gasket requirements and the joint fitted to the engine. A motorcycle application alone does not verify every aftermarket or modified headpipe arrangement.

Should I choose gasket quantity from the engine model alone?

Count the port joints being opened for the planned repair. Individual gaskets let you order that quantity, while the ten-pack provides extra stock for later work; package size does not define the repair scope.

Not sure which part you need?

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