Boyesen 563 Power Reed Valve System for Polaris

The Boyesen 563 Power Reed valve system is engineered specifically for Polaris applications, delivering enhanced engine performance through advanced reed valve technology. This high-performance reed assembly utilizes Boyesen's patented dual-stage fiberglass design to optimize intake flow dynamics.

Key Features:

• Patented dual-stage fiberglass reed petal construction for superior durability
• Increased airflow and air velocity compared to stock reed valves
• Improved throttle response and mid-range power delivery
• Precision-cut petals for optimal sealing and performance
• Direct replacement for OEM Polaris reed valve assemblies

Boyesen Power Reeds are designed to maximize the efficiency of your two-stroke engine's intake cycle, allowing more air and fuel mixture to enter the combustion chamber while maintaining proper sealing. The dual-stage design allows the reeds to flex more efficiently across the entire RPM range, resulting in noticeable power gains throughout the powerband.
