Sieg,
Hopefully this isn't a hijack. The picture you posted brought back fond memories of my brother Mike (he is gone now).

Here he is on his 1966, 250 Harley Sprint (Aermacchi), he called it the Thumper. He bought it used right after coming home from Vietnam, we was a Jarhead too.

We used to have blast on this thing.
