Jul 7, 2008 - Yesterday I picked up an early Harley 4 speed tranny with some other parts. Heres a good link to determine case and vin numbers. For Big Twin transmissions 1936-1964 there are 4 types of transmissions cases that were.

S&S Cycles in Wisconsin makes carburetors, performance parts and entire V-Twin engine assemblies for Harley-Davidson and Harley-Davidson-like motorcycles like Big Dog and Ironhorse motorcycles. The engines cost about as much as Harley engines, but they are hand assembled, come with large displacements and have a long-established reputation for craftsmanship. Several very visible marks make them easy to recognize. Nokia n95 series. S&S motors also have unique engine identification numbers which, because S&S manufactures fewer engines, are shorter than Harley engine identification numbers.
