Boyesen Pro Series dual-stage reeds combine a carbon-fiber top reed with a fiberglass bottom reed for unrivaled performance. The Pro Series Reeds are more responsive than our traditional Power Reeds. The carbon-fiber top reed has excellent response characteristics that provides even quicker acceleration, stronger throttle response, and more over-rev than our standard Power Reeds. The fiberglass bottom reed provides stability and longer reed life.
This cover acts as an "adjustable leak jet" to fine tune the accelerator pump squirt.
Eliminates "4-stroke bog" when used with correct jetting. Allows the use of correct carburetor settings to optimize performance, starting and reliability. Improved low-end performance with much better throttle response. Investment cast and finished to precise tolerances with internal high volume vertical check valve. Fits all motorcycles and ATVs using a Keihin FCR carb. Easy installation instructions (including online video) and template.
