1970 Honda CL350K2 · Fuel System Buying guide

Follow the fuel path before choosing parts

These three products serve distinct connections. Checking the tank thread, the carburetor’s needle-seat application and the drain-screw seal keeps one symptom from becoming an unnecessarily broad rebuild order.

Use the tank connection as the first petcock check

The petcock uses an M16 × 1.5 connection and replaces 16950-292-000. Check the tank thread, clearance and hose routing, especially after a tank swap. If the repair is at the filler instead, the linked chrome cap has a gasket already installed.

Separate bowl sealing from fuel-level components

A drain screw with its O-ring addresses the bowl drain; the needle and seat reference 16011-287-004. For wider service, the linked rebuild kit requires round bowls and covers one carburetor per kit. Identify the fitted carburetors before deciding between a targeted part and the larger order.

Ordering questions

Will the petcock fit a non-original tank?

Only after its connection is confirmed. Compare the tank fitting with the offered M16 × 1.5 thread and check the mounting space and hose routing before relying on the motorcycle application.

Should a leaking bowl automatically get a rebuild kit?

Identify whether the leak is at the drain, bowl seal or another component first. The separate drain screw includes an O-ring, while a broader kit should be chosen only after its application and needed contents are confirmed.

How many rebuild kits should I order?

The linked round-bowl kit rebuilds one carburetor. Confirm that your fitted carburetors have the required round bowls, then order one kit for each carburetor being rebuilt and check any essential kit contents.

Not sure which part you need?

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