I'm happy to be a member of such a great forum for SOHCs. I recently bought a 1973 CB750 K3 with under 8,000 miles. The guy I bought it from said it was sitting in a barn since '79. He put fuel, and I'm assuming oil in it, hooked it up to a car battery, and it started right up. The guy said he nearly hit the floor when he heard it. Supposedly it has a big bore kit and a new clutch that was installed before it sat in the barn. I'm looking to make it a cafe racer, but first gotta get it road ready
Update: I am now a happy owner of a 1976 CB750 F1. This is my project bike. I have to sell the K3. If you know anyone that might be interested let me know!
Also, if you plan on being in the city and want to talk bikes send a message.
