1970 Honda CL450K3 · Fuel System Parts Buying guide

Start at the tank, then identify the carburetors

The fuel-system selection includes tank fittings and carburetor service parts. Choose by the assembly being repaired: a tank connection, a cap mechanism or an identified carburetor needs its own fit and contents check.

Parts to consider

Check a changed tank directly

The petcock uses an M16 × 1.5 thread. Compare the actual tank connection before ordering, even when the frame retains its CL450K3 identity. Check the cap hinge and latch arrangement at the same time so a replacement or custom tank does not leave the order dependent on assumptions.

Use carburetor identification to narrow the order

The linked rebuild kit is specified for carburetor models 14H and 14L and rebuilds one carburetor. Read the fitted carburetor markings before choosing it. A broad motorcycle-year range cannot establish that replacement carburetors use the same service parts or jetting.

Buying questions

Does a chrome cap order include a complete latch assembly?

The chrome cap’s confirmed contents are a gasket and hinge pin with E-clip. The latch is a separate listed assembly; check the cap package contents before assuming a latch will arrive with it.

How do I choose a petcock for a replacement tank?

Check the actual tank connection for the specified M16 × 1.5 thread and compare the installed fitting arrangement. The motorcycle’s year alone cannot identify the connection on a swapped or custom tank.

Does one carburetor rebuild kit cover every carburetor on the bike?

One kit rebuilds one carburetor. First confirm that each carburetor being serviced is a specified 14H or 14L model, then order the number of kits required for the identified units.

Not sure which part you need?

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