Description
A reed valve’s responsiveness directly impacts throttle feel and acceleration—and the BOYESEN Pro Series Reed delivers measurable gains in both. The dual-stage design combines a carbon fiber top reed with a reinforced fiberglass/epoxy bottom reed, giving you the quick piston speed response of pure carbon fiber without the durability penalties. If you’re running a RAD-40B PSR-040 carburetor and want maximum horsepower and torque with reliable, consistent throttle control, this is the upgrade that makes the difference.
