Exhaust Valve for Rotax Max Evo Engines, particularly for the Evo Rave assembly. This valve actuates and opens at certain RPMs to operate the Rotax Max Evo kart engine properly.

The valve opens at mid-range in the power band, expanding power and performance of the Max Senior and Master engine.

This valve is also known as the power valve 'blade' by some.
