KZ900 Carbs - have you seen a set like this before

The cylindrical part where you might expect the fuel adjustment screw appears to be sealed off.
Does this look unusual? I recall if I have seen carbs like this before.

As contrasted with similar carbs having bottom located mixture screws for adjusting the pilot circuits.
The pilot adjustment screws on some carbs might have a plug to discourage EPA-hating reprobates from overly enrichening the pilot circuits. Where fitted, such plugs are readily removable by a very shallow drilled metal screw inserted and pulled out with a pair of pliers. But watch out for the circling black helicopters.
Good Fortune!

Yes the carbs have the air screws on the side. I don't remember seeing the bottom parts blocked off before - maybe I have seen it before and just forgot.
Thanks for the info and I will continue with the cleaning.

I looked high and low for a bottom view of the KZ900 carbs that clearly show the particular area involved, and have tentatively concluded that your posted picture is the only such picture on the planet. :lol:
Hopefully others will have better information about the differences, and which might be more typical.

Oh yeah, mine even have that same steel plate that goes across the tops of the carbs.

The bike is for the most part stock but that's no guarantee that these carbs were on it when it left the factory.

As to the settings for carbs with both a pilot and air screw I would suggest one of 2 ways to do it.
Either screw the pilot screw all the way in and in essence block it off, and then use just the air screw for adjustment. This was actually recommended by Kawasaki,via microfiche for the kz650 B models that had both types of adjustments on the smaller vm24 carbs.
The other would be to set the pilot screw (bottom of carb) at 1 3/4 out from lightly seated, and the air screw (side of carb) at 1 3/8 from lightly seated. I would then only use the air screw for any additional tuning needed.

If the pilot enrichment screw is seated all the way in, won't this stop all pilot circuit flow?
thanks,Nick
