The standard brake disk for 73 Kawasaki Z1 comes with the 8K stamped on them, some after market (or other similar bikes) brake disks might come with different numbers stamped on them, I'm gonna attache the pictures of original brake disk you can compare them and see if 7V is same as 8K. Hope it helps and let me know if you need more advice. Best
From experience, Kawasaki Z1 is a very famous bike, and was one of the first to use front disk brakes, and I actually had a used one, some years ago. Hope the info and the picture helped you with your problem and comment if you need more advice.
