Torsion Bar Valve Springs
The CB400T used an unusual torsion bar valve spring system instead of conventional coil springs, which was innovative but can be a maintenance headache — inspect carefully as worn components are harder to source today.
Watch the Carbs
The twin CV carburetors are prone to gumming up from ethanol-blended fuels after sitting, so always check for smooth throttle response and clean idle — a full carb rebuild is often needed on neglected examples.
Strong Beginner Resale
These bikes hold steady value in the classic commuter market due to their approachable LAMS-friendly power and retro appeal, making well-kept examples surprisingly easy to resell if you decide to upgrade.
