Abstract
Abstract An air inlet means for use with the two cylinder internal combustion V-type engine. The air inlet device includes a carburetor, an air cleaner and an air associated with each cylinder. Such carburetors and inlet pipes are arranged so as to be positioned between the engine cylinders with the air cleaners extending outwardly from between the cylinders so as not to interfere with the fuel tank.
