Gov’s Late 30’s/Early 40’s Drake Knucklehead

This is Gov’s late 30s/early 40s Drake Knucklehead.  It is a water-cooled, custom Knucklehead motor that was used strictly for dirt track racing in the late 30s and early 40s.  These types of motors were run in Midget Cars.  We are completely rebuilding and having to manufacture some of the parts because of how rare it is.  He plans to put it back in a race car.

 

Mike’s 1939 Knucklehead

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.

Larry’s 1941 Knucklehead Restoration Update

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.

Tandy’s 1939 Knucklehead

We have a special guest writer for this newest post.  We met Tandy approximately 15 years ago when she came in for some help with her Knucklehead, and she has been a faithful customer and friend ever since.  Enjoy.

I bought my bike in 1981.  It was love at first sight and I bought her before I could even kick-start her.  The current owner started her and despite the suicide/jockey shift, I rode off as if she had been mine for years.   

The first few years I lived on her but then life happened ….. my family all sold their bikes but I kept her and rode alone.  

I made seat, fender, and paint changes to her over the years but could never find anyone that really seemed to understand her until I met the guys at HWC.  They kept her running well for years then one day I had the money and they had the know-how to rebuild the engine and transmission, as well as make some chassie modifications.   

Thanks to the guys at Highway Choppers I will be riding my scooter for as long as I possibly can.  And yes, a ridge frame at 50 is not as easy as it was at 20 but it is still just as much fun!

Chris V. 1947 Kuncklehead

This is Chris V.’s 1947 Kuncklehead partial restoration.  We are rebuilding the motor and transmission and installing it in his chassis.  We are also installing new handlebars as well as replacing his aftermarket tanks with original ones.  After all the changes are made the final step will be painting to match.

This is the first time the engine ran after restoration.

 

Engine Case Repair

These cases were brought to us severely broken, and the customer wanted to save them.  We have the capability of repairing these cases almost as if they were new.  As you can see from the pictures, the top part of the case was broken completely off.  In order to repair them, we fit them back together and dovetail ground all the cracks.  Then we proceeded to weld the case back together.  Early Harley cases are extremely difficult to weld due to the quality of aluminum used in the castings.  We have a very talented certified welder, in house, that makes it look easy.  Once the cases were repaired, we fit both case halves together and finished alining all surfaces such as motor mounts and cylinder deck.  Once the machine work was complete, we went back and refinished the surface to give it a factory original look.

Here are some before and after photos.
