The GRex Tvalve was born from a desire to build a reed cage that manipulates the engines acoustic activity and provides a high velocity intake charge. The valve is made from a Carbon fiber composite with a proprietary set of carbon/fiberglass reeds.
The spacer helps keep tension on the reeds as well as capturing the screws so that they cannot come loose. The same reeds have been run for a season in a Honda CR500 Outlaw Kart without degradation, however, different engine set ups and in particular different pipes could affect the reed longevity. The Tvalve has been tested in QRC engines, SUP engines, and our house test engine with good success with regard to power and reed longevity.
The spacer is available in silver or red. Gasket included.
