Abstract

The cylinder head for a twin V-twin motorcycle engine contains an intake port entrance lies in a plane oriented at an angle of less than ninety degrees to another plane defined by the center lines to the intake and exhaust valve guides and the entrance is characterized by a rectangular shape that is tilted from the horizontal plane of the head so that one of the three corners to the rectangular shape is lower in vertical position than the other three. The floor, the lower side between the two lower most corners, is oriented perpendicular to the intake valve guide.
