This machine is the only one ever built.
It is an overhead valve of a flathead 741 30.50 indian.
The conversion was done by Elmo Looper
(the purchaser of Crocker motorcycles inventory) in about 1959.
Among the many modifications are:

Stroked to 45"; Installation of BMW cylinders and heads; Installation of magneto; Use of Indian Arrow frame; Bates seat and Headlight.

The machine weighs in at 300 pounds dry. It was said to have been very fast and was the prototype for a modified production scout that was being developed to take advantage of the plentiful war surplus Indian scouts.

Unique engine; handmade in Sweden:

8507-768x1024 husky

INSOMNIA: Husqvarna SRM1000 (Swedish Racing Motor). Martin Carlgren (Ringö Chop Shop) from Sweden built this chop. The engine was built from some incomplete Husqvarna engineering drawings from 1948, for a 1000cc v-twin. The design was by Husqvarna engineer Fulke Mannerstedt, and was built using Husqvarna parts. Husqvarna had produced 350cc and 500cc OHV v-twins in the thirties for racing, and they did very well, but the 1000cc version was never built. The bike won the "Builders Choice" award at the 2017 Born Free custom show (number nine) in California. The frame is a 1930 Harley VL.

The info board says it was "handbuilt from incomplete drawings found, dated 1947-1948 of a Husqvarna/SRM 1000cc/61" V-twin that was never completed or built before. Magnesium cases and cam cover; magnesium cylinders with steel linings; aluminium heads; magnesium rocker boxes."

Husqvarna 1000: More info and pictures .... however, the article is miustaken... the engine was actually built by Magnus Romeborn who works for Volvo Penta in Gothenburg, Sweden... and there are enough parts to build at least another 8 engines!

"Kala Bendu": 815cc v-twin. Crankcases are home-cast from melted-down cylinder blocks. The barrells are made from FOUR 200cc barrells from the Bajaj Pulsar 200 (an Indian brand that has a miniature copy of a Honda CBF500). Two 200 cc barrells are stacked vertically for each new extra-long barrell, presumably with a new long liner. The con-rods are "Norton with a stroke length of 100mm" (as used on Norton Model 18 490cc OHV single). However, the bore size is 72 mm as opposed to 79mm bore of the Norton model 18. The pistons are from a "Honda Excelent" (Honda Civic) car, and the cam is a one-off. Timing belt is from a Mitsubishi L300 van. The bike has just been finished in time for the Kustomfest 2017 show.
