I went ahead and bought a bike not doing much research before. It is a 1978 R80/7 with 69k miles on the clock. Went to the auction house to buy a car and ended up with this bike. Seeing it in this state made me feet quite bad for it and had to have it so I can bring it back to life. The auction house did fire it up and it sounded alright for the few seconds they had it running.
This is how it looked when I first got it.
Had to get the fairing off right away to get it in the truck.
