I mainly ask because I seem to have inherited a set with a parts 650 I picked up a couple of months ago. As soon as I can get it organized, I will post some photos, to confirm what they are. I reckon somebody else can let me know if I have it wrong anyway.
The plan had been just to tidy them up for sale, as they are far too big for any of my bikes, and it seems they have some intrinsic value. If the OP was suggesting they can be worth $250-300 USD, then it is worth the time to clean them up and sell them off. (Or, as always for fair prize to a fellow KZer.)
I don't mind. Put up some pics before you spend any money on them.
The photos aren't great, as they are just off my cell phone, but I think they are at least sufficiently good to figure out what these are.
They've clearly been modified for vacuum ports by somebody, which among a couple other things suggested to me that they were maybe the VM33s, which as per earlier did not come with synching ports. I did check the bore diameter quickly at the fellows house, and I seem to remember it being a touch OVER 33mm, but not an awful lot. I currently have then soaking in some hot soapy water to clean them up at least a little before moving on.
If this isn't enough info for a good identification, then let me know, and I can take some more photos or look for other distinguishing marks.
To id Mikuni carbs there is a number stamped on the bolt flange in front of the choke lever
on the number one carb (left side sitting on bike).
Jonny I may be up for those VM33's what kind of bucks if you don't touch them and sell as is.
Not doubting your ability but first thing I'll do is break them down for a few hour ride in the sonic cleaner

Rather than starting another thread I thought I'd put it here. It appears the port going to the sediment bowl is smaller than the inlet tubes. I've always suspected the big carbs were starving for fuel at WOT or high speed riding. Didn't have that problem with the stock one. The 33's have two feed lines and a common galley connecting all four carbs. The needle seats are large with strainer screens on each one. The port might be my next mod.
These carbs have 2.0 slides. In the chart they should be 1.5 for Kawasaki. The slides are very expensive. I use to have a manual that told how to file them to make them 1.5 but it was stolen. I could tweak the air settings but that won't effect the pilot settings. Here's a revised clip.
The bike finally "leaned out." It had to get pretty hot to do it. I got back home and adjusted the timing and pilot screws. Much better. The bike pulls harder and some of the noise has gone away. I'd rather not go back to the #70's. I may go leaner still. I'll do the cam bearings and readjust.
