They were turned out of 8.0 mm brass hex stock.
Overall length is 27.8 mm
Threaded section length is 9.0 mm.
Thread measured 6.18 mm dia, 1mm pitch or 26 tpi?
Length of hex section is 4mm.
Nipple bulge is 6.44 dia.
Thin part of nipple shank is 5.0mm.
Bore is 2.5mm dia.

Now let's see if I can scan this diag.

I put this one on the bay. I got the spark plug out, kept drilling it on the mill. When it was down, that spark plug pulled out like a coil spring. Whatever, threads cleaned up fine. Hope someone gets it for an early production engine. So far it's going to Australia.

The following info (caps as in original) is credited to

DAVE MARSDEN
DECEMBER 1998
ONE: DEVELOPMENT OF THE Z1 900 SUPER FOUR

BUILT INTO THE HEAD WERE FOUR NIPPLES, ONE FOR EACH CYLINDER. THESE WERE LOCATED INTO EACH CYLINDERS INLET TRACK AND USED FOR TAKE OFF POINTS TO BALANCE THE CARBS. WHEN NOT IN USE THEY WERE BLANKED OFF WITH A SMALL RUBBER PLUG.
THIS PROVED TO BE TROUBLESOME AND KAWASAKI MODIFIED THE CYLINDER HEAD FROM ENGINE NUMBER Z1E-2201 ONWARDS. THE MODIFIED HEAD NO LONGER HAD THE NIPPLES IN THEM, BUT INSTEAD MODIFIED INLET RUBBERS WERE SUPPLIED WITH THE NIPPLES BUILT INTO THEM. THE PART NUMBER FOR THE MODIFIED HEAD WAS 11002-012 AND THE MODIFIED RUBBERS WERE 16065-022 FOR THE RH AND 16065-023 FOR THE LH. TWO OF EACH WAS REQUIRED. THESE WERE HANDED DUE TO THE FACT THAT THE NIPPLES STUCK OUT AT AN ANGLE TO ASSIST THE FIGMENT OF THE CARB VACUUM BALANCE PIPES.


Good Fortune! :)
