CB450 and CL450 DOHC Twin '68-'73 KeiHin 2nd and 3rd Gen CV's
These carbs come in a few versions and can be found on CB and CL 450 Twins made '68-'74. Only the 2nd and 3rd gen '68-'74 are covered by me. I strictly rebuild the 5-speed models. However, the engines can accept all variations. 14H, 723A, and 723B are the most common for my rebuilds. These models all look the same, but have some different internals and tuning. 723B's are shown below. These are the type that have the larger air screw that uses the o-ring and washer like more modern carbs.
