Yes it is...I can't pull up any info on a quad 4 carburetor ??? I wonder what the original application was ??

I'll try to message the kid.
I'd imagine its from an inline 4 cylinder street bike engine.Looks that way csuse of how the 4 carbs are bokted together.

Some carbs have the vaccum slides,these do not.

Heres the issue with motorcycle carbs.
Rebuilds are expensive.

I think if we divide the 84 cubic inch by 4,and get one single carb to match the engines cubic inch per cylinder we would be ok.

However im currently looking at the solex 34 pic 3 carbs, $70 shipped on amazon.

The flow master sounds good too.

I haven't watched the video but I had a Honda 750 years ago that was 4cyl, 4 carbs.

I quit experimenting and went with the Empi because the gains between the empi and trying to get multiple carbs to work was just not worth the effort.With the Empi dumping the gas straight down between all the cylinders and being raised it seemed to be the best choice. That and the cost and the ability to modify the carb easily.

Guy replied Honda CBR 600 carbs

I had a 99 cbr 600 and it had 4 vaccum slide style.

These look like early 90's

One other plus for the EMPI is that with the modified intake manifold and the EMPI I haven't had one instance of carburetor icing since the conversion. With the original carb and manifold it was a real issue.

Yes the icing with the stock carb and a backfire was the reason for the helicoil to blow out of my head.
