Reed Valve for Yamaha FS1

Newly developed reed valve with carbon fiber reeds for the Yamaha FS1. The flat-ground surface ensures that the carbon fiber reeds seal tightly against the aluminum housing rather than against rubber, making the entire assembly more stable and durable over time. The reed valve performs very well across all power classes, from stock to heavily tuned. THIS PRODUCT IS COMPATIBLE WITH , YAMAHA , FS1 , FS1-DX , and FS1-SE
