This is a very nice and properly contoured Kawasaki heat shield. It has been repainted and looks great.
It is definitely Kawasaki. the hole pattern is unmistakable.
Possibly from an late 60's or early 70's. Kawasaki enduro
I can tell you what is not 1971 G4TR 100 --close fit dimensionally, but the mounting holes didn't line up.
1972 F7 175. About 2" shorter
If I had to guess probably a 90cc late 60's model. No guarantees
It is 17" on center in a straight line in between mounting holes. total length is 21" at its longest point
