Bending the fan is easy. Like kurt said, take the belt off and bend each blade so they clear the radiator.
I popped my first restore... ...after I had totally restored it.
I did too. A '74 CB 750 K4 Honda, five months after I finished it. Got t-boned. Slid my second restoration ('76 Stingray) under the back end of a lifted pickup in the rain three years later.
