1974 Honda CL450K6 · Fuel System Parts Buying guide

Build separate tank and carburetor repair lists

Tank hardware offers distinct cap and latch contents, while carburetor products are packaged for individual service tasks. Comparing those scopes first helps prevent missing fittings and duplicate repair pieces in the same order.

Parts to consider

Choose the cap package around the retained parts

The chrome cap includes gasket and hinge pin with E-clip. The matte-black assembly also specifies the latch, return spring, latch pin and C-clip. Inspect the tank mechanism before choosing either, and account for the included pieces before adding another latch or hinge-hardware order.

Keep carburetor coverage precise

The related kit is described for one carburetor, and the related holder supplies one holder with gasket. The float valve contains a needle and seat. Confirm the installed carburetor and the kit’s detailed contents before deciding whether a separate float-valve purchase overlaps with the proposed rebuild package.

Buying questions

Which tank details matter after a tank swap?

Check the cap’s mounting mechanism and the petcock connection on the replacement tank. The offered petcock has M16 × 1.5 threads; a model-year match cannot establish that a substituted tank uses that fitting.

How should a multi-carburetor repair affect the kit order?

The stated service scope is one carburetor per kit. Identify the units being repaired and confirm kit compatibility for each before converting that repair count into the number of packages to purchase.

How do I avoid buying a float valve twice?

Compare an itemized kit inventory with the separately sold needle-and-seat set. The current kit description does not enumerate all components, so establish overlap before combining both products in the order.

Not sure which part you need?

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