Rotary Valve 147 Degree

Description

Rotary Valve 147 Degree

• This is a new 147 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: 420924508
