This motor came from an original unrestored 1939 Knucklehead.  The customer wanted to keep the original patina on the motor.  We disassembled the motor, cleaned the inside, rebuilt all the internal parts, but left the outside in its original condition.  This will look very nice in his unrestored, original 1939.  Below is the start-up video.

This customer is from Pennsylvania and brought us this motor that had supposedly just been rebuilt, but he was leery so he wanted us to take it apart and check it out.  We found many issues with the motor so we completely rebuilt the motor again.  Below is the start-up video.
