Parts and fitment guide for your 1978 CB400TI
The carburetor kit includes several main-jet sizes, two float needles and other service pieces, but it is sold for one carburetor. Do not use the number of needles to infer that one kit covers both carburetors.

Check the product application, dimensions and pack quantity before ordering.
Identify your 1978 Honda CB400TI
Check the frame identification, engine markings and registration details together. A photograph or paint colour alone cannot establish model year. An engine swap or previous repair can change the parts your bike needs.
Honda CB model guide
Match the CB400 application
Match the kit to the carburetors fitted before selecting jets from its contents; supplied jet sizes are not a tuning recommendation for a modified engine. The oil-filter element replaces reference 15412-413-005 and the listed alternatives. Confirm the component rather than transferring CB400F Four applications to this page.
Fitment questions
Do parts from another CB400 model fit my 1978 CB400TI? Only when the product listing explicitly includes both applications. CB400F, CB400A, Hawk I and Hawk II names do not establish interchange. Check the installed engine, carburetors, brakes and controls against the listing.
Does an OEM reference mean the part is genuine Honda? Not by itself. Aftermarket parts can quote the Honda number they replace. Look for an explicit genuine Honda description if brand origin matters; “OEM-type” or “replaces OEM” does not identify the manufacturer.
