The cheapest complete set of these carbs on ebay is $175 plus shipping. There's two for $142 & 150 + shipping but they are missing fuel bowls and/or floats etc. There is a 1973/74 set with accel pump but it's missing a bunch of parts @ $130-ish.
I feel that $150 + shipping is a more than fair price for these, as cleaned sets are listed for $350 & 399 on ebay.
These are VM26's not 28's (measure 26.18mm with my big calipersbat the outlet, so 26mm at the center slide area where it steps down in diameter a tiny bit on VM's., no accel pump, but in good functional condition and came off a running bike that we couldn't get the 1/8-1/4 throttle range dialed in correctly (not set up for a GS750 engine). If it were mine I'd dismantle and clean thoroughly but we just sprayed them through the passages last year and blew out with air, put some new o-rings on and adjusted floats, new bowl gaskets, and he ran them for the tail end of the 2016 season. When we started modding his bike and fine tuning it, I opted to swap on a proper set of GS750 carbs onto his bike for ease of tuning, as these are KZ1000 spec. Not sure exactly which year/model but they are KZ1000 not GS750/850/1000. Mikuni VM26.
these have no pilot air screws on the side, only pilot fuel adjustment screw on the bottoms, and two fuel tees on the side between 1 and 2 and between 3 and 4, not one tee in the center and two couplers on the side carbs as others are configured.
5CN8 slide needles. I'm guessing 1.5 main air jets based on machinist drill bit size checking as a bore gauge.
They had 110 mains but currently 102.5. I have only one extra set of 110's and they are the old school aftermarket nylon jets which I'm not sure would handle today's ethanol content so well. I can throw in if you want them. Either 15 or 17.5 pilots, I can't recall what's in them currently.
Numbers stamped on the mounting flange are:
102
4A
I think they may be KZ1000B4 carbs but the B1 models also had the no air screw but fuel screw instead, 2 inlet tees between 1&2 and 3&4. I think the B1 had a different slide needle though. My notes got ruined by carb cleaner or gas spill and I can't read the B4 specs that I had written but I think the slide needle was the same so I'm thinking they are KZ1000B4 vm26's.
choke lever does not look like it was in too rough of shape cosmetically, but same as the engine cases on the bike we took these off of, previous owner brushed on some silver or gray paint onto the side of the choke lever. Not on the carb bodies thankfully
