A friend of mine recently lost her husband. His pride and joy was a ´78 Yamaha 500 SR. Black, aluminum wheels, 9,200 miles and perfect except for a tear on the left side of the seat. Until a month ago it never sat outside. Very powerful and like new. She is willing to sell but has no idea what to ask and I can´t seem to locate any to establish a price. Does anyone have any ballpark ideas? Bob
