The first bike I ever worked on was a 74 350F. I spent months on a frame-up rebuild including new Honda pistons /rings, the worst paint job you've ever seen, learned that torque specs really do mean something, and ended up selling it to my brother for $200 (I was REALLY strapped for cash and living on his couch). He took it out and dumped it in a ditch the next day.
It's still sitting in our parents garage 2 hours away (I haven't figured out how to get it into mine yet) awaiting a more patient hand to revisit the rebuild, paint, etc. One day...
