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).

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. :whistle:

What size are the air screws you have in there?

Sorry, got the screw mixed up with the air jet :blink:

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

Maybe the Air Jet size needs changing for your screws to achieve the effect you are after...:unsure:

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.
