Description
The TOP PERFORMANCE reed valve (manufacturer reference 9931620) is designed to optimize the management of fuel and air flow in membrane engines. Replacing the original housing without modifying the rest of the engine, it aims to restore liveliness to the acceleration range and improve throttle response.
Its patented "double V" design facilitates the passage of the mixture and reduces disturbances at the intake. The inlet, which has a diameter twice that of the original, promotes more efficient crankcase filling, useful on large diameter carburetors and oversized cylinders. The part is supplied with a 28 mm Venturi for suitable tuning and optimized performance.
Ideal for urban users and 50cc scooter riders looking to regain engine responsiveness. Compatibility examples: YAMAHA AEROX R (SA421), MBK OVETTO 2T ONE, KEEWAY MATRIX 50. A simple solution to restore responsiveness to your intake without heavy modifications.
