want to convert ZN to single carb ideas?? 8/6s

they do it to gold wings any insight or ideas welcome...trying to figure out what i could use to fabricate intake

Why would you wish to do that?  It seems like a backwards step.

I have seen a 1300 where an inlet manifold was fabricated & a twin choke Weber carb was mounted drawing from the side.

Over sometime ago I toyed with this idea of one carburetor for the bike, I was so frustrated with the 3 carbs that I was considering to do this project, I even bought a used Mikuni HSR 42 researched intake manifold designs, definitely not an easy task. 
well time has passed and I finally was able to workout my issues and the bike is a rocket ship. 
Maybe one day I will try just because 

It would be different!

get rid of all fuel injected stuff....a cafe needs to neat and clean....will it work??
