Frequently Asked Questions

How many carburetor holders and O-rings are included and required?

One carburetor holder with one O-ring is included. The listed Honda CB400 and CB450 twin-cylinder models use two holders, so two assemblies are needed to replace both intake connections.

What does a cracked Honda carburetor holder cause?

A cracked, hardened or poorly sealed holder can create an intake air leak, causing a lean mixture, hanging idle or difficult synchronization. Check both holders rather than tuning around a leak.

How should the new carb holder be installed?

Clean the cylinder-head sealing surface, seat the supplied O-ring without pinching it and tighten the fasteners evenly to Honda specifications. Confirm that the carburetor is fully seated and supported without straining the holder.
