Topic: 1974 CB750K4 Carburetor Years

[computerpulse]

What years do the carburetors from a 1974 CB750K4 Cross?  I just broke one and someone has a 1973

I think carbs from 71 - 76 will fit the 74. They should be K carbs. I dont know if the F carbs ar different.

F1 (75/76) carbs are the same. The later 77/78 (F and K) are different
There are some jetting changes between the carbs mentioned, but if you transfer your original jets in, then no problem.
One point to watch out for is that Honda changed the fuel tap from the right hand side to the left hand side about 1974/1975. This was  done so that riders could turn the reserve on with their left hand and keep the throttle open.
This is worth  mentioning as at the same time the carbs had their idle adjusting screw transferred from the left hand side to the right hand side. Same carbs but would make it a little awkward to get to the idle if they do not match.

The carb bodies are the same thru '76, there were a couple jetting changes and the linkage changed somewhere in there.  I'm not sure when they went to unit linkage.

The unit linkage started at the K1 model. Any carbs from 71-76 (F or K) should be usable, with the provisos above
