ABSTRACT:
A valve train in an internal combustion engine, and a method of adjusting the valve timing setting of a valve in such a valve train, are disclosed. In one embodiment, the present invention relates to an engine that includes a crankcase with a cylinder, a valve, a push rod, and a rocker arm supported by the crankcase and coupling the valve to the push rod. The internal combustion engine further includes a cam rotatably supported by the crankcase, and a cam follower arm having first and second ends and, proximate the second end, having bottom and top surfaces. The cam follower arm is rotatably supported by the crankcase about a pivot point proximate the first end. The bottom surface proximate the second end slidingly interfaces the cam, and the top surface proximate the second end interfaces the push rod.
