Upgrade the intake performance of select Yamaha personal watercraft with the Moto Tassinari V3140-794-2 W/C Delta 3 Reed Valve. Designed for Yamaha WaveJammer, WaveBlaster, and WaveRaider models with twin-cylinder engines, this reed valve assembly uses a patent-pending snap-together cage design with symmetric reed petals for consistent operation and dependable fitment.
The patent-pending reed tip shape is engineered to accelerate the air mixture over the reed tips, helping improve airflow through the intake system. Depending on the overall engine setup, this design may support a dramatic horsepower increase, additional RPM, higher efficiency, improved fuel economy, and longer reed petal life. The Moto Tassinari Delta 3 provides a performance-focused replacement or upgrade for riders seeking improved response and competition-oriented engine performance.
Fitment includes the 1987–1990 Yamaha WaveJammer WJ500, 1993–1995 Yamaha WaveBlaster WB700, 1996–1997 Yamaha WaveBlaster II WB760, and 1996 Yamaha WaveRaider RA700. Verify the model and engine application before ordering. Manufacturer part number: V3140-794-2. Vendor part number: V3140-794-2.
