CB750 carbs on CB77

Just curious if anyone had used the cb750 carbies on the cb77. I think Bill Silver mentioned in a post someplace that they offered a performance improvement .

I have heard of it as well. Actually I think I have heard of them used on the Dream. One problem though, I think you need the carb from a 750 K0 model. They had the carb where the cable entered the top of each carb. Later models used a linkage and a cable worked the linkage.

The KO model is being used today.
It does require a mount with rubber for it to be installed.
I sold a 5 speed CB77 which had the 750 carbs.
I have a complete set (one missing bowl) and if the #3 carb has the choke lever changed it makes 2 sets for the CB/CL72/77 engines. .........lm..................lm

I have two off of a K2/3 has the linkages. I think I saw someone had fashioned a adaptor.

I am wondering how much difference these engines when standard will perform with 28 mm carbs

I'd say 26 to 28 is no big deal as you are using carbs designed for a 152 piston area and the 350 is a 175 piston area.23 difference.
That's about the size of a .40 model engine. ...............lm
