Sea-Doo 159 Degree Rotary Valve GS/ GSI/ GSX RFI/ GTI/ GTI LE/ GTI RFI/ GTS/ GTX/ GTX RFI/ HX/ SPX/ XP/ 3D RFI/ Challenger/ Explorer/ Speedster/ Sporster
- his 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).
