Abstract
Greater torque and power are realized in V-twin motorcycle engine with a cylinder head having a combustion chamber that incorporates two flow relief areas, one for each of the intake and exhaust ports, located on opposite right and left sides of the combustion chamber, and flow resist areas about the remaining portions of the respective port's periphery, obstructing gas flow into the flow resist areas. The foregoing arrangement defines a gas reversion path from the exhaust port that zig-zags through the chamber to the intake port, increasing the length of the path and reducing the adverse effect of reversion. A rectangular shaped intake port entrance and an accompanying rectangular shaped manifold passage provide for input of greater volume of combustible gas and a D-shaped exhaust port exit contribute to the effectiveness of the combination.
