Z1A Enginge Number Pads

I had this under a similar heading in "Archives"- under Engine- Z1A Eng Numbers! (Page 5), I have not worked out to retrieve it and continue the post. So I'll start again (within reason!).
On reviewing, the last post in "Archives", there is a CORRECTION.....
Bottom line of last post, should read:
Last unit sighted {80 mm} bordered pad 5 digits (plain surface).... Z1E-32887

As most are aware, I have posted this on many forums and I must say, although the response was good, I'm disappointed and surprised, that no one (other than Mark & Yoshi) has seen a Z1A engine number between Z1E 24591 (65mm){Mark} and Z1E-29217 (85mm){Yoshi}. That's approx 4,500 engines!

Let me briefly state what I'm trying to establish.
MAIN OBJECTIVE ~ pertaining to Z1A's
What engine number was the first of the 80 mm bordered pads? Was this first 80 mm pad of a cast/ stamped form? (estimated approx Z1E-27500).

While we are at it, what engine number was the first with six numerical digits?.

Thats is a very good question,and my basic guideline is;
73 motors,had no border.
74 motors did.
According to my Kaw USA fiche dated May,1972,there is no such thing as a 72 Z.Motor number 00001 is a 73.I will reveiw your question again ,at work,and post the correct answer,per USA specs.

ZDoc, I agree with you that, the US and some other countries called the first Z1 (that was manufactured about Aug '72 and first appeared at the Cologne Show in Sept '72) a "73 model".
Also, the Z1A that was first manufactured about Sept 1973 was known as a "74 model".

Assuming the Z1A started with Z1E-20000, which Kawasaki have asserted. The question I am posing is, when did they first get that border around the pad? I have enough proof that they were still being produced without the border up until, at least Z1E-24591. It is thought that they changed from a 65mm pad to an 80mm pad at the same time they introduced the border. (my guess is ZIE-27500).

I've had a reply from Bjorn (Sweden), so the sequence, over the area of interest w.r.t. Z1A engine number pads, now reads.~
Last unit sighted {65 mm} un-bordered pad, 5 digits ... Z1E - 24591

First unit sighted {80 mm} bordered pad, 5 digits (milled/ cast) ... Z1E - 27752
Last unit sighted {80 mm} bordered pad, 5 digits (milled/ cast) ... Z1E - 27771

First unit sighted {80 mm} bordered pad, 5 digits (plain surface) ... Z1E - 29217
Last unit sighted {80 mm} bordered pad, 5 digits ... Z1E - 32887
First unit sighted {80mm} bordered pad, 6 digits ... Z1E - 033474

Trying to fill the gaps! Stay with me.

Ciao (ZOG-Germany) Thanks for your submission.
Please adjust the above summary, last entry to read:
First unit sighted {80 mm} border pad, 6 digits .... Z1E - 033419.

Filling the Gaps!
Just to hand, another milled/cast Z1A Engine Number Pad ....
{80mm} bordered pad, 5 digits, (milled/ cast)..... Z1E - 27744.
I am now convinced that this milled/cast pad was a product of Kawasaki and that the method was later discarded. I have still to establish how long they ran for (When they started and when they finished, I would guess that they would have started with the start of the borded pads).
A photo is available on an e-mail... Haven't worked out how to produce it for the forum yet!

For those interested, I have just had notification from Kari from the Z1 German forum that he has Z1E-27376 and this makes four of these cross-hatched 85mm engine pads to be sighted. (photo available).
This make the range of this type of engine pad from Z1E 27376 to Z1E-27771.... 395.
