Boyesen Power Reed Dualstage Kawasaki Kx/Kdx 80-85 79-85, Honda Cr80 86, Yz60-80 75-83 Tech 7 the Shield is great forOne 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.
