Carburetor repair or rebuild kit for the Honda CB450 and CL450 models. This kit is the most complete kit available for the 450 twins! It fits Keihin carburetor models 723A, 727A and 723B and which were used on the 5 speed 450's. The needle jet holders tend to be the first to get damaged due to corrosion and improper sized screw drivers bending the slotted end. If you can manage to get out the old one, this kit comes with a new one for a nice easy installation and removal.
This kit is for 1 carburetor, the 450's have 2 carburetors. Kits are sold individually. So, you'll need 2 of these for one bike.
We also sell this kit as a set of 2, and we have main jets sold individually if you need other sizes. We also carry a kit that comes with floats!
