ABSTRACT:
A motorcycle powered by a two cycle internal combustion engine having an improved induction system that has a vertically extending intake pipe so as to permit a wide latitude of leaning of the motorcycle without interference from the induction system. The induction system serves the crankcase of the engine through a rotary plate type valve that has a helical connection to the engine output shaft so that the timing of the opening and closing of the intake port can be adjusted. A servo motor adjusts the helical connection under the CPU so that the timing change mechanism need not be powered directly by the engine.
