ABSTRACT:
An intake manifold for twin carburetors or twin air control throat bodies for a motorcycle or the like having one or more cylinders where the physical space is limited comprising a hollow central plenum chamber and hollow carburetor or air control throat body mounting flanges on each opposing side adjacently perpendicular to at least one side communicating with the intake track of at least one cylinder. In the case of two opposing cylinders, each cylinder communicates with the hollow central plenum chamber through opposing openings and the perpendicularly mounted carburetors or air control bodies. When a cylinder intakes a fuel mixture from the carburetors the fuel mixtures from each carburetor converge in the hollow plenum chamber where the direction of flow is turned toward the cylinder without physical impact with a physical structure during direction change. With the cause of air control throat bodies the air flowing through the manifold controls the flow of the air in the same manner as the fuel mixture.
