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.

We are restoring this for Larry.  The motor went through start-up already.  We installed the motor and transmission in the frame and are continuing the restoration process.

This motor came to us a couple of years ago and the customer, who is from Alaska, wanted to rebuild just the lower-end.  After completing the lower-end, the customer took it home and installed the heads.  Several years later, after completing the motor, he called to request that we do a motor start-up on our motor run stand.  He was happy that it went well.
