Semi hi-jack maybe

They seem to sell quickly on flea bay for around $300.00 give or take.
They were once THE carbs to use, many moons ago…..

Jonny wrote: I hope I am not highjacking here, but I am curious about whether or not there is much of a market for VM33's. I've read through this whole thread, and get the feel that at least Steve is having success with them.

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.)

Pics soon,

Cheers,
Jon

I don't mind. Put up some pics before you spend any money on them.
Steve

Thanks all for helping with the identification.

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.

Thanks in advance,

Jon

Yup, just like mine.
Steve

Great,

Thanks Steve. Appreciate the confirmation. I guess I will give them a little bit of love and a good clean up and sell 'em off to someone who can put them to good use.

Cheers!

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
no sense you doing it then me do my thing with them

PM sent Dave!

AFTERMARKET PETCOCK
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.

What size are the air screws you have in there?

I don't understand. I got them from jetsRus
Steve

Sorry, got the screw mixed up with the air jet

Maybe it doesn't matter, but observing the Jets R Us "Air Jet Chart", it shows various sizes available with the BS30/97 1.2 standard specification Pilot Air Jet for the KZ1000/1100

Check out the chart below the exploded view and red highlight over Standard Jetting Specifications VM33 Smoothbore
