I believed the cvk carbs i thought where gpz600 are actually from a 1988-89 Australian zx900r, according to the needles and jets in them .
Using a set of ZR550 carb boots i have successfully fitted them to my 1982 GPZ550 h1 with factory airbox.

I wasn't expecting the air box to fit but there it is,
They also use a single pull cable instead of the push/pull arrangement on the 600's

Current engine is K&N Pods, and all else ZX550 with 4-1 Exhaust. Cam timing is stock ZX550 Exhaust and KZ550 Intake, using ZX550 Cams.

I'd recommend buying a wide band and tune for road use. I've posted this before but here is what I have yet to install. A good friend of mine has been using his Wide Band to tune his CV32 Carbs to his 12:1 615cc and Web Cam Engine. He is such a good friend, that he will not help me with additional jetting questions on my set up, till I have the LC1 installed. He says using it will answer most of my questions. LOL!!!

In this picture, I am using the needles on the right with shims added. Tomorrow I will have the carbs off, and will list my current settings.

These are CV32 ZX900 carbs, check out the attachment in my first post, australian 900's got the 32s.
i thought i was getting a 600 set. clues are black paint, single pull cable. jets, needles
I just cant see that 90 main being any good for power, but maybe im wrong
I think my engine specs are going to be similar to yours other than the K&N Pods. Maybe down the track, but for now its going to be a modified airbox with UNI filters.

That interesting i didn't realize your using ZX600 needles. for some reason i though you had aftermarket needles .In this picture, I am using the needles on the right with shims added. Tomorrow I will have the carbs off, and will list my current settings.
the N27C needles look more like the N27L than those pointy 52Q's your using
yes wide band is in my future for sure , One of the guys i work with circuit races and uses a AEM to help dial in the carburettor on his racecar and swears by it.

o rings for the fuel and vent tubes
zx600 factory pro jet needle kit i found for half price
keyster gasket float valve kits
i think that should cover it other than a few more sets of mains
the engine has kz550 timed zx550a cams.
10.5:1 comression
4-1 exhaust
Modified stock airbox uni filters
I have also welded an O2 sensor bung onto the exhaust so i can use a LM2 to dial it all in.
Before I order some more mains should I also add some 38 pilots to the list. I see Cory is using 38's but the pilot airjets on his cvk32's are larger than my set or should I just wait and see how many turns the pilot screws end up needing.
old and new needles

You can use the standard 35 pilots, but having a set of next size up 38's might be needed if the readings deem necessary. I haven't used the Factory Pro Jets.
What is stamped on the needles you are showing on the right above? N27L???
I have found a difference in the CV32 Carb from the 1985-1992 ZX600C Era. The butterflies are shown in the two below, noting the little pin hole and lack of one in the other. Also there are not any air holes in the throat of the lower opening, also visible.

The Factory pro needles are 0964g-76p-40t.2 for richer at 5000 to 7000 the recommend getting 0964g-72p-40t.2 needles
Think I going to bench set them to
110 factory pro main jet - not sure what the equates too
Factory pro needle - clip in middle groove third from the top
35 pilot jet- what's in it already
Pilot screw 2 turns out - std.
these 32's dont have holes in the butterflys and all look identical with 3 bleed holes.
edit. using phone so photo is not the best
