"A complete Z nut would appreciate some help.
Has anyone seen a Z1A engine with the numbers on the pad surface that look like it has been surface milled or stamped.
This relates to Z1A Engine Numbers~
As most Z1 nuts are aware, the Z1 had their engine number on a plain pad about 65mm long and this was continued thru to the Z1A, at least until about engine number Z1E 24600. Sometime later, they changed to a pad about 80 mm long with a raised border surrounding the pad.
The theory is: This type of Kawasaki Z1A engine number pad was the first of the 80 mm pads, produced somewhere around engine number Z1E 27500 - November 1973. It is thought that Kawasaki were endeavouring to make the pad more difficult to change, hence, make the engine more theft-proof. They, for some reason, dropped the concept shortly after they started it and settled for the border only, as the deterrent."
Any ideas??
