Do with it what you want. My only advice is.... 45 flatty's use to be cheap, solo frames, servi frames, motors and trans'. Guys would give the stuff away 20 years ago. I picked up a running motor (1939 wl) about 18 months ago for $1000. I was just looking on ebay at motors and see them selling for 2-3 grand as runners. Solo frames 2-3 years ago in my area were selling for 300 all day at swap meets. The least expensive I've seen as of recent was 700. I have a hacked up 1971 sporty but I bought it already hacked. I have a hacked 1967 bsa but I kept the origional frame and front end (and odds and ends) incase I ever want to go back to origional.... At swap meets you can find old sporty frame already chopped for 2-300 pretty frequently.
