1971 Honda CB350K3 Exhaust Gaskets & Hardware

Choose the gasket quantity for the exhaust work on your 1971 CB350K3. A single gasket and a ten-pack share the stated exhaust-port application. Inspect the pipe retainers and nearby mounting pieces separately so the sealing order matches the joints and hardware you will disturb.

1971 Honda CB350K3 · Exhaust Gaskets & Hardware Buying guide

Choose the gasket pack size for the job

Two cylinder-head exhaust connections give a clear count for a standard twin. Select individual gaskets or workshop stock, then inspect the separate pipe retainers rather than assuming gasket packaging includes fastening hardware.

Use the smaller quantity for a single repair

The individual gasket is supplied as one piece. It lets you order the number needed without committing to a ten-pack. Count the joints being opened and keep any spare gaskets clearly identified for future work on a compatible exhaust-port application.

Treat mounting hardware as a separate inspection

The headpipe seals, retaining collars and fasteners play different roles at the cylinder-head connection. Check the hardware already fitted and identify any missing or damaged pieces using the correct parts diagram. Neither gasket package is presented as a complete exhaust mounting kit.

Buying questions

Do two individually sold gaskets cover the standard twin?

Yes. The original CB350K3 uses one exhaust-port gasket at each of its two cylinder-head connections. If the exhaust has been modified, also check the pipe manufacturer’s installation requirements before ordering.

When does the ten-pack make sense?

Choose the ten-pack when you want spares for repeated exhaust work or several compatible motorcycles. It contains ten gaskets rather than a specially matched collection of different seals for one motorcycle.

Are the headpipe collars and nuts included?

The gasket items supply the exhaust-port sealing rings. Inspect the retaining collars and fastening hardware separately, and identify any replacements needed before taking the exhaust apart for the planned repair.

Not sure which part you need?

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