Boyesen Power Reed Dualstage Yamaha Yz125 88-92, Tri-Z 250 85-86 Ignition Cover Protectors SX and MXGP racing-inspired shoulderOne reed petal is NOT enough! Boyesen's revolutionary dual stage reed design delivers more usable power than stock. Stock single stage reeds operate most effectively within a relatively narrow RPM range and are limited because of the single stage design. Boyesen's one soft reed on top of one firm flow through reed gives you a wide range of intake control, plus increased intake velocity. Your original reeds can't possibly duplicate that performance.
