Description
  • This is a new 159 Degree Rotary Valve.
  • A rotary valve refers to the fuel intake valve of earlier Sea-Doo two stroke engines.
  • The rotary valve is driven off of a gear on the rotary shaft in the crankcase between the cylinders.
  • This motion allows the intake port to be opened and closed in time with the engine power pulses.
  • The rotary valve allows the port to have no restriction.
  • Rotary valve engines are a very efficient design with complete control of airflow into an engine.
  • They allow the air/fuel mixture to flow without any airflow restrictions (unlike like reeds).
  • Fits: 420924502
