Stage6 Viton® Reed Valve Block MBK Booster / Minarelli Vertical

Stage6 Viton® reed valve box, designed for 2-stroke Minarelli vertical engines (MBK Booster, Yamaha BWS, etc.). Equipped with Viton® reeds, known for their high resistance to heat and fuels, this reed valve box improves engine responsiveness and intake reliability.

The reeds control the entry of the air/fuel mixture into the crankcase. More efficient reeds ensure better sealing and more precise opening/closing, optimizing engine filling.

Function:

• Regulate the intake of the air/fuel mixture
• Prevent mixture kickback towards the carburetor
• Improve engine response
