About the Honda CB400T
A guide to the Hawk twin’s carburetor years and essential repair parts.
Honda introduced the CB400T in 1977 as an air-cooled twin with three valves per cylinder. It followed a different engine design from the earlier CB400 Four. For a Hawk repair, identify the twin first, then use the model year and carburetor markings to select service parts.
Choose between the earlier and later carburetor kits
The CB400T rebuild kits below separate 1978–1979 from 1980–1981. The engine gasket set spans 1978–1981, while the rear shoes shown cover 1980–1981. Keeping those three ranges separate helps you put together a repair order without carrying one part’s coverage over to another.
