Description
Polini Evolution Reed Valve
Not suited for Jog CV.
The Polini Evolution reed valve offers much greater flow than the standard reed block, and faster petal action due to the carbon fibre construction of the reeds themselves. The benefits of this reed block are much more obvious in scooters with 70cc kits installed. Its intake angle is precision-tuned on a computer for ultra-smooth airflow, so the fuel-air mix moves exactly how it should. Plus, the reed block’s vulcanized surface helps the carbon petals seal tight, keeping crankcase pressure perfectly balanced for peak performance.
The vulcanized rubber surface has excellent sealing properties to prevent backwash and low crankcase pressure.
