Boyesen PW-38 PowerWing Carburetor Velocity Intake Carburetors & Accessories

The Boyesen PowerWing is a precision-engineered carburetor velocity stack designed to maximize airflow efficiency and power output on both 2-stroke and 4-stroke motorcycles. This aerodynamic intake device installs between the carburetor and airbox to optimize air velocity entering the carburetor, resulting in measurable horsepower and torque gains across the powerband.

Key Features:

• Aerodynamic wing design maximizes air velocity and minimizes turbulence for improved power delivery
• Precision-molded wing channel reduces jet needle disturbance for more consistent fuel metering
• Enables cleaner carburetor jetting for crisper throttle response and acceleration
• Precision fit ensures perfect alignment with carburetor bore and simple installation
• On 2-stroke engines: improves power from idle to midrange without sacrificing top-end performance
• On 4-stroke engines: delivers power boost from idle through over-rev range

The PowerWing's scientifically-designed shape straightens and accelerates incoming air before it reaches the carburetor slide, improving mixture quality and combustion efficiency. This results in stronger throttle response, improved low-end and midrange torque, and overall more usable power throughout the RPM range.
