I think it's 72 or 73. But the cylinder seems to be younger, it has the small fins on the cam chain side which I think makes it post '75??
The front brake is a bit of a hassle. The CB 350 brake I bought from the wreckers seems to be from two different models. When I tighten the axle, the brake plate locks up on the drum. I need to run a little spacer in the middle but that reduces the swept area of the brake shoes, so I might have to do a bit of machining on the back of the brake plate.
I'm waiting for the top triple clamp to arrive then I can really get moving.
Pretty sure '72 was the only year without the fins on the camchain side of the cylinder. That's why my guess as to which year your bike is was '73-'75. In '76 the bike was redesigned a bit and the carburetor came straight back in the center of the head rather than off to the right side as yours does. The early bikes were known as side ports, the later ones, center ports.
