Sea-Doo Rotary Valve

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). 159 DEGREE VALVE 1994 Sea-Doo XP Rotary Valve 1995 Sea-Doo GTX Rotary Valve 1995 Sea-Doo HX Rotary Valve 1995 Sea-Doo SPX Rotary Valve 1995 Sea-Doo XP Rotary Valve 1995 Sea-Doo XP800 Rotary Valve 1996 Sea-Doo Challenger Rotary Valve 1996 Sea-Doo GSX Rotary Valve 1996 Sea-Doo GTI Rotary Valve 1996 Sea-Doo GTX Rotary Valve 1996 Sea-Doo HX Rotary Valve 1996 Sea-Doo SPX Rotary Valve 1996 Sea-Doo XP Rotary Valve 1997 Sea-Doo Challenger 1800 Rotary Valve 1997 Sea-Doo Challenger Rotary Valve 1997 Sea-Doo GS Rotary Valve 1997 Sea-Doo GSI Rotary Valve 1997 Sea-Doo GSX Rotary Valve 1997 Sea-Doo GTI Rotary Valve 1997 Sea-Doo GTS Rotary Valve 1997 Sea-Doo GTX Rotary Valve 1997 Sea-Doo HX Rotary Valve 1997 Sea-Doo SPX Rotary Valve 1997 Sea-Doo XP Rotary Valve 1998 Sea-Doo Challenger Rotary Valve 1998 Sea-Doo GS Rotary Valve 1998 Sea-Doo GSI Rotary Valve 1998 Sea-Doo GSX Rotary Valve 1998 Sea-Doo GTI Rotary Valve 1998 Sea-Doo GTS Rotary Valve 1998 Sea-Doo GTX RFI Rotary Valve 1998 Sea-Doo SPX Rotary Valve 1999 Sea-Doo Challenger 1800 Rotary Valve 1999 Sea Doo Jet Boat Speedster SK Rotary Valve 1999 Sea Doo Jet Boat Speedster Rotary Valve 1999 Sea Doo Jet Boat Sportster 1800 Rotary Valve 1999 Sea-Doo GS Rotary Valve 1999 Sea-Doo GSX RFI Rotary Valve 1999 Sea-Doo GTI Rotary Valve 1999 Sea-Doo GTS Rotary Valve 1999 Sea-Doo GTX RFI Rotary Valve 1...
