The Boyesen Power Reed Petal Set 6130 is designed for motorcycle enthusiasts and competitive riders looking to optimize their two-stroke engine's performance through superior reed valve efficiency. Its key benefit is the patented dual-stage design that balances crisp low-end throttle response with high-RPM horsepower gains, though users should note that installation requires basic mechanical skill to ensure proper seating and seal for peak performance.

The Rev-Plate replaces the restrictive stock reed stop, allowing the reeds to open fully and efficiently without obstruction.
While not always required, fine-tuning your carburetor jetting is recommended to take full advantage of the increased airflow.
It is good practice to inspect the reed petals whenever you perform standard top-end maintenance or air filter cleaning.
No, these are specific to certain models. Please verify the part number 6130 matches your engine specifications.
The stiffness of the bottom reed is designed to withstand the higher pressure and velocity of high-RPM operation, ensuring consistent horsepower.
Verify that the reed petals are seated flush against the cage and that no gaps exist where air could leak.
Check your carburetor jetting; the improved flow may require a slightly different fuel mixture for optimal combustion.
Inspect the reeds for cracks or chips; debris in the airbox can damage petals over time.
To install, remove the intake manifold to access the reed block assembly. Carefully remove the stock reed petals, ensuring no debris enters the engine crankcase. Install the Boyesen Power Reeds according to the included diagram, ensuring the Rev-Plate is seated correctly against the reed cage. Inspect the reed cage for any uneven surfaces or burrs that could prevent a perfect seal. After installation, periodically check the reeds for fraying or chipped edges, especially after long periods of heavy use. Clean the intake tract regularly to prevent foreign matter from damaging the petal tips.
