Product Details

The Boyesen 567 Power Reed Valve System is engineered specifically for Polaris applications, delivering enhanced engine performance through advanced reed valve technology. This high-performance replacement reed system utilizes Boyesen's patented dual-stage fiberglass design to maximize intake efficiency and throttle response.

Key Features:

  • Patented dual-stage fiberglass reed petal design for superior durability and flexibility
  • Increased airflow and air velocity compared to stock reed valves
  • Improved throttle response and horsepower gains throughout the powerband
  • Precision-manufactured to OEM specifications for direct bolt-on installation
  • Engineered specifically for Polaris two-stroke engines

Boyesen Power Reeds are designed to withstand the demanding conditions of high-performance riding while providing consistent power delivery. The dual-stage fiberglass construction offers an optimal balance between stiffness and flexibility, allowing the reed petals to open and close more efficiently than traditional designs. This results in better cylinder filling, stronger mid-range power, and improved overall engine performance.
