ABSTRACT:
A rocker support assembly for a motorcycle internal combustion engine. The assembly comprises a pair of rockers positioned in spaced relation from each other, a breather housing, and a pressure-responsive member. The housing at least partially defines an inlet aperture, an outlet aperture, and a passage in fluid communication between the inlet aperture and the outlet aperture. The passage is positioned substantially between the rockers. The pressure-responsive member is disposed in the passage and is operable in response to pressure differences in the passage to permit or inhibit fluid flow through the passage from the inlet to the outlet. A filter element is disposed within the housing such that substantially all fluid flowing from the inlet aperture to the outlet aperture passes through the filter element.
