Abstract
A device for introducing air into the exhaust system of a V-type motorcycle engine. The device includes an air manifold advantageously positioned within the V of the engine with passages extending to each exhaust passage adjacent each exhaust port. A control valve run by vacuum admits air to the manifold while reed valves control the passageways to each exhaust passage. The portion of the passage extending through the cylinder head in one embodiment includes a simple bore in tangential intersection with the exhaust passages. A pipe is positioned within the bore which has nozzles therethrough for proper introduction of air to the exhaust.
