the twin or the four?
I remember both well, never rode the twin, but did once test drive a four cylinder CB400, they upped it from a 350 to 400 at some point, made a beautiful sound and the stock 4 into 1 pipes looked real purty.
A few months ago I met a guy at a convenience store riding one of those.
The darned thing was like new.
He had found it in a warehouse in the Northeast where it had been sitting for a few decades.
