I also have a 74 850 frame with the same 2 scars on the front downtubes. The bike was called " The Jumper" , sold to me cheap by Mike Jones who worked in the Movie stunts industry. Sidestand lug area was bent inwards too , telling me many kicks occurred whilst on the prop. My guess is crash bars fitted too tightly to both downtubes. :?
