Looking at them both and I'm leaning more towards the 550....bleh, I'll have to check them out tomorrow or Tuesday. See which one will give me a better offer.The 79 (actually 79 1/2, they started the year with the SOHC motor) is a dual cam motor, 4 valves per cylinder. These things really rock, that is the one I had. Was the fastest 750 when it came out.
I would be torn, as this one also looks well cared for. But the 550 is lighter and smaller, had a stiffer frame, and really looks good as a cafe. The 750 Sport is pretty cafe from the factory.
At 12K miles, the 550 is "just broken in". I bet the 750 is also low milage, still has the stock exhaust and looks way too clean to be high milage.
Thats a tough choice, it su&ks to be you (in the best way, it looks like you couldn't go wrong with either).
I'm really glad I don't live around there.
"dyna s" electronic ignition replaces the point plate and plugs right in. have to do an initial timing adjust then forget about it. had one for my kz900, worked great for about $100. (that was in 1980, don't know what you'd have to pay now, or even if they are still around. just a thought.)Do these or the '77 CB 450 4 cylinders use point adjust ignition. Ihad an old cafe KZ 650 that was fun to ride, but man those points would always rattle out of adjustment or the engine would die from the rain.
