This 5-Petal Boyesen Race Dual Stage Reed Kit is the direct replacement for the factory Mercury Racing High RPM reed cages found in many high performance applications.
These composite dual-stage reeds work in unison to perform efficiently throughout the entire powerband. The difference in stiffness between the top reed and the bottom reed allow the reeds to respond quickly and accurately to changes in engine pressure.
This translates into quicker acceleration, crisper throttle response and increased horsepower throughout the powerband.
The 5-Petal Boyesen Race Dual Stage Reed Kit includes reeds, reed stays, short screws, instructions, Boyesen decals and two (2) small Buckshot Racing #77 decals.

Why do we recommend Boyesen?
The reed petals in all 2 stroke engines undergo a significant amount of wear and tear. At peak RPM, reed petals open and close hundreds of times per second, causing a single reed to lose its ability to regulate flow rates effectively over time.
This can lead to a decrease in reed petal reaction and a loss of peak horsepower consistency. Boyesen's dual-stage reed design offers more usable power compared to stock single-stage reeds. Stock single-stage reeds are most effective within a narrow RPM range due to their design limitations.
In contrast, Boyesen's dual-stage reeds, with one soft reed on top of one firm flow-through reed, provide a wider range of intake control and increased intake velocity. The dual-stage design also allows for the replacement of the stock reed stop with a Rev-Plate, enabling the reeds to open freely and function efficiently.
The bottom reed's multi-port feature creates more channels for the charge, delivering increased velocity to the intake ports and generating more overall power.
The dual-stage reeds work together to perform efficiently throughout the entire powerband, with the difference in stiffness between the top and bottom reeds allowing for quick and accurate response to changes in engine pressure.
This results in quicker acceleration, crisper throttle response, and increased horsepower throughout the powerband.
