Boyesen’s revolutionary dual-stage reed design delivers more
usable power than stock. Your original one-stage reed operates most effectively only within a narrow RPM range. 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.

  • Faster opening and closing
  • Greater low pressure (Low-throttle) response
  • Greater velocity and flow area
