1913 Harley Davidson twin engine wanted

The above has to be a 1911,1912 or 1913 HD twin ,the engine below went in a bike like this.

A fellow i know recently discovered this 1913 HD twin engine. This technology is before a recirculating oil pump was introduced, note also no valve covers, they surface in 1914 models.
If you have one of these early engines, email me. i would like to build a racer, just go to the profile page , look for contact info...

This flat block is where the Bosch magneto was positioned.

Early Schebler carburetor, HD later adopted Linkerts.

Production of singles and twins for 1913 are 12,904 motorbikes.

1936 Knucklehead in Japan w dual 1915 Schebler carbs

I found this very unusual dual carb 1936 Knucklehead on YouTube, belongs to a Japanese rider,whats really unique is that those are 2 1915 era Schebler carbs attached to a intermediate manifold that bolts up to the M5 Linkert 3 bolt manifold that bolts up to the knuckle heads.

I couldnt enlarge the foto. The other interesting feature was the really slow idle and the fellow hooked up the shifter to the top motor mount. Just searching YouTube in Japanese script brings up a whole other world of genuine custom Knuckles, Panheads etc, No way in hell i can read the Japanese blogs on Japanese custom bikes, Amazing machines worthy of further research.

Production of all motorcycles in 1936 for HD was 9,812 motorbikes .

Unknown WW1 German motorcycle & ace

WW1 ace with unknown motorcycle...If you can ID the bike , email me,

My guess the year has to be 1910 era, the fins are all horizontal ...beehive style. After 1911 most motorcycle makers introduced vertical fins on the top of the head.

Here one can see the narrow deck and the loading of torpedoes as an officer looks on.

Amazing to think all these submarines and their crews are at the bottom of the ocean.
