Mikuni CV Carb ID

LONG time lurker to the forum and thank everyone for the excellent info. I have a pile of parts from when I bought my KZ900 and along with it came a rat KZ1000 in pieces. That was 5 years ago and I'm finally cleaning the shop and selling off the 1000 items along with left overs from the 900. I have a Mikuni CV carb set I'm trying to ID and cannot do so. I miced it up as a 34mm unit and its shown in the photos.

Can someone help ID what bike these fit?
Thank you
Pete

Some sort of Mikuni flat slide CV carbs (obviously). They look similar but not identical to the GPz900 carbs.

I agree. While hunting around on eBay I found a few sets belonging to Suzuki bikes. Why this is mixed in with the KZ stuff is beyond me. I am starting to suspect it's a fluke.

Thanks again
Pete
