Part: Carburetor Float for Honda CB550K3 / CB550K4 / CB750K (77-78) / CB750F (77-78) / CB750A (77-78)
Why You Need This: In 1977, Honda switched up the carburetors found on both the CB550 and CB750 series of motorcycles. The new carburetors made by Keihin, were the "PD" models, with a completely different design they their predecessors. The new "PD" carbs use a synthetic "plastic" float with a long trapezoidal shape over the round shape floats found in the older generation of carbs. Nevertheless, the original plastic floats can become brittle or crack, which causes the floats to fill with gas, therefor not floating as intended. If one or several floats are no longer buoyant our high-quality replacement float can be quickly swapped for an original. Sold individually, one float fits one carburetor and includes the needed pivot pin, 4 floats will be needed per bike.
Carburetor Rebuild Kits are available if you find yourself doing a entire carb bank overhaul. Once together, make sure your carbs are in balanced out with our Carburetor Synchronization Tool Kit.
Installation Tip: To confirm that your float is defective submerge in a clear container of gasoline and watch to see if one side starts to sink lower than the other after a few minutes. While the plastic body is robust, the metal mount bends quite easily so be gentle when installing. Setting the recommended float height to 14.5 mm is easy with our carburetor float gauge,
