Abstract
This invention is directed to a dual barrel carburetor for a motorcycle. The preferred carburetor includes a novel combination of a fuel bowl assembly, a metering assembly, a main body assembly, and an air plenum assembly. The dual barrel carburetor includes annular discharge booster venturis associated with a main fuel delivery circuit. An idle circuit opens downstream of the throttle plates. A transfer circuit discharge port is positioned across the throttle plates. The combination of the idle, transfer and main fuel circuits ensures the smooth delivery of fuel throughout all operating conditions of the motorcycle engine. The plenum manifold assembly includes a pair of air passages in fluid communication with one another to permit a final opportunity to optimize the fuel delivery to the respective combustion chambers.
