The 750 looks like a 75..
Nice XL 350 in your avatar...
LOL. You would be right sir. 11/75 build 76 model. In my haste to get out without my Cousin's three sons seeing me take them, I never looked until now. 11/75 build , does that make it a K5 or K6? I also has a BAD PATCH on the clutch cover. No plan to restore, but if I can get it running myself, I'll do a rough cafe bike out of it. The CB450 is a two cylinder , so parts or sold whole. Missing parts already but I will have to come up with a kick start for it to turn it over.
Thank you. That XL350 is as found, but cleaner, except for pipe, carb, tires, and repro side cover decals. 5k miles now.
