That's a nice old bird John.
Thought about one, or a M21, but never ventured too far down that road. My Dad learned to ride a motorcycle, on a M20, whilst serving with the Royal Signals in Ceylon (Sri Lanka) before the end of WWII, including "off road" through the bush!
Put him right off motorcycles for life and his refusal to ever get involved with my various machines, "Your machine mate, you ride it, insure it, fuel it and fix it, I'm having nothing to do with it."
He never did and always thought that I was barking.
Probably Right!
Good health, Bill
