Back in the 80's i bought a set up similar to this,that a local lad bought and fitted to his (i think?)z650. It was a cool set up. One of my best mates is building a z650 with a Gpz11 engine fitted with a one off stainless manifold and an SU carb. It was cheaper and easier than finding carbs for the once fuel injected engine.

Ive done an SU conversion on a suzuki blandit before,as have one of my mates. Car carbs rule.

Every silver lining has a cloud...
