Boyesen Power Reed Dualstage Kawasaki/Yamaha Kx80 86-87, Blaster 200 Atv 88-06, Yz80 87-92 3.5 The RFX Elite sprocket hasOne 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.
