Description
This is a new rotary valve. A rotary valve refers to the intake of earlier Sea-Doo two-stroke engines. It is driven off a gear in the crankcase between the cylinders, opening and closing the intake port in time with engine power pulses. The rotary valve allows the port to have no restriction and provides complete control of airflow into the engine, allowing the air/fuel mixture to flow without airflow restrictions. Applications: 1988 Sea-Doo SP, 1989 Sea-Doo SP, 1990 Sea-Doo GT, 1990 Sea-Doo SP, 1991 Sea-Doo GT, 1991 Sea-Doo SP, 1991 Sea-Doo SPI, 1991 Sea-Doo XP.
