just noticed this morn that the z1b eng that i was shifting about in the garage (again) has no raised lip were the numbers are stamped, the stamping looks right enough though
any body seen this before

Early engines have no lip.

didnt the lip appear somewhere early in the z1a range?

hi mick, i thought that, zed 1015 is right it was the early engs, just thought ide ask the question

A pic would help.
The early number pads with no lip were shorter in length than the later ones.

cheers zed 1015 but i must have had to much juice this weekend, it is a z1a eng, the z1b eng is still in bits in a box

I think as Mick says, early Z1A engines were also without the lip, I think Garn did a bit of research into it so he could tell you more, but I have one around 27000 with no lip.

Z1 motors had a shorter "pad" for the stamping.

Bas, as Malmojoe & Jimmock have mentioned the Z1's & early Z1A's were without lip and only had a shorter pad [65mm long].
I think, to prevent theft, and over-stamping about #27700 Kawasaki tried this...
extending the pad to 80mm snd giving the overall surface of the pad a lip.

Also, for a short period a checkered surface. The checkered surface must not have been successful as, I think, certain number stampings interfered with the surface and caused pieced of alloy to fall out!

I have found this only went for a few units [approx 400 to 1000 units], after which it changed to the original large font then to the last font which is smaller and slightly italic. It also gained an extra digit along the way. I have seen anomalies around this # 27700 sequence, however, as they were so good, I had to accept them or embarrass the owner.

To my knowledge, the Z1B had the 80mm pad with lip and had the six digit small slightly italic font

RegardZ.

cheers garn1
