Boyesen 645 replacement Power reeds combo kit - 2 set -Yamaha YFZ350 Banshee

Product Overview:

The Boyesen Power Reeds Combo Kit maximizes airflow, intake velocity, and throttle response using a patented dual-stage reed design. Each system is specifically engineered to match the year, model, and displacement of your machine for optimal performance. From low-end grunt to high-RPM horsepower, this system enhances your machine's responsiveness across the full powerband.

Key Benefits:

• More Air Flow: The dual-stage design replaces the stock reed stop with a Rev-Plate, allowing reeds to open fully and function with maximum efficiency.
• More Air Velocity: The ported bottom reed creates multiple channels for air charge, increasing the intake flow velocity to the engine.
• More Overall Power: The difference in stiffness between the top and bottom reeds ensures precise response to engine pressure, resulting in quicker acceleration, better throttle feel, and horsepower gains throughout the RPM range.

Dual-Stage Reed Design Features:

• Lightweight, responsive top reed for low RPM & partial throttle operation
• Ported bottom reed delivers max flow for high-RPM power
• Quicker acceleration and surer throttle transitions
• Improved fuel efficiency and longer reed life

Achieve maximum power through optimized air intake, acceleration, and fuel distribution – engineered by Boyesen for peak performance.
