Need help identifying these Mikuni BS34 carbs

[1978GS750E]

Like the title says, I need help trying to figure out what Mikuni BS34 carbs I found on my illustrious winter project.

These have smaller bowls, and it looks like they interlock? (Notice the empty holes on the bowls, each bowl is threaded on the bottom on one side???)

There is also 2 fuel inlets, 2 vents and 1 vacuum fitting.

I am sure there are some linkages missing, as there is no choke and no idle adjustment knob on this set.





Anyone ever come across anything like these? Know what bike(s) they would have been on?

Thanks,
Ron

Those are not BS34's, at least, I've never seen any BS carbs that have flat slides and look like those.

Edit: they look like early GSXR carbs. No idea on exact model or engine size.

I may have found these carbs on Ebay? At least they look like the ones that I have, and mine have a 34mm throat! The fuel, vent and vacuum ports look the same and the bowls are the same.

Of course mine are painted black, like the rest of the bike!

Looks like they are Mikuni CV34 carbs!
