Thanks Dale......Wouldn't it be ironic if my Cheney is one of those two you posted?Of course it's doubtful we'll ever know but they're in the right part of the world!
I also think they're two different bikes. Besides the sprocket, the front fender,shocks and seat are different. I really wanted to anodize my tank its original red like that pair but I've grown on the bare aluminium look now. The disco ball in my garage reflects off it so well!
Did you ever get the piece on you Cheney Sachs organised with Ken?
