I sold my 84 Robinson Cruiser with HL Turbo flight cranks to Alans around 2000 when I had a clear out of bikes. That was a lovley bike....
I also sold him my Robionson 20", but that was battered and sketchy as hell to ride, so not too bothered about that.
My Dad sold my sisters Turbo Lite F&F in the late 80s and he really regrets it now.
I gave my mates son my Powell and Peralta sword and skull with Indys and slimeballs to borrow for a while, and the little tosser got it nicked when he left it at his local ramp.
