CB750K-K0 '69-'70 SOHC KeiHin B750A
All of the CB750 SOHC carbs made from '69-'76 look similar, but they are VERY diverse. You have to pay close attention to the specific version to correctly rebuild and the bike they are currently installed. Even the motors can be swapped, so this can even include the '77-'78 years. They are found to be interchanged and very mixed-up so just replicating current parts installed, is a recipe for disaster.
This type shown is pretty easy to instantly see the difference and is only found on the first two years of the SOHC CB750. They utilize a one into four throttle cable and each carb top has an independent cable inserted. Each carb has it's own idle adjust, but they do have a choke linkage system with one lever like the later CB750 SOHC carbs. The carbs themselves have no marking as the marking is on the bracket that holds the four together. The brackets are super easy to break, so it is hard to tell if it was the original. They also use brass floats. Nearly all the parts, in some way, are specific to these two years. The set below was customized and some later parts were used like the redundant o-ring crossover tees.
These carbs are VERY hard to properly set-up on the bike and not recommended unless you are actually restoring a '69-'70 to stock specs.
