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 .
