Did you eat lead paint chips as a kid?

Probaly, I lived in ghetto Buffalo, Lots of lacquer fumes too, I started priming, sanding and painting when I was 15.
Washed parts in trichloroethylene with no gloves, always had a 5 gal. pail of carb cleaner (Gunk Solder Seal) the real bad stuff in the garage. Just to name a few. Could explain it. Made it to 57 now, no growths or goiters growing on me yet, anyway.
But, I hope you got the motorcycle for a decent price, it looks nice!
And all the titles go by the frame Z1F--- Don't worry about engine, stamp the #'s yourself.
I have dozens of times including frames over the last 40 years.
They use a simple 1/4" basic, straight up stamp.
Now Harley was a whole different story, they purposely changed angles, had different star shapes, off center. Every few years back in the early days of Pan & Shovel head. They changed them up. Which the DOT new about.
Sorry if I offended anyone.

Then if you must stamp them, then what number? unless you have a record of the original engine number. Kawi frame and engines were never sequential, from maybe one digit out on early three digit numbers, up to several hundred out for the later ones.

So by guessing what the number should be, and unless you are certain that the original engine has been scrapped, you could accidentally clone your new number an existing motor which is a lot more dodgy than just leaving it blank.

Don't stamp numbers into it. Ed
