      BOYESEN offers this reed valve block for YAMAHA YZ 250, YZ 250 X and FANTIC XX 250 2005-2027. On a two-stroke engine, the reed valve sits between the carburettor and the engine. Its reeds open to let the air-fuel mixture in, then close to stop it coming back out.

      Why fit this reed valve?

      The benefits:

      • Better throttle response and more torque.
      • Reeds that are lighter and quicker to react than the originals.
      • Stronger pick-up at all revs.

      Why choose BOYESEN?

      Boyesen invented the dual-stage reed: a soft petal for low and mid revs, a stiffer one for top end, for more torque everywhere.

      When should you replace the reeds?

      Split or chipped petals, or petals that no longer seal on their seat: the engine spits back, lacks pick-up and uses more fuel.

      Specifications and fitting tips

      • 100% Aluminium body with aerodynamic internal surfacing
      • 4-way aerodynamic directional dividers that distribute the angled charge evenly without flow loss
      • Manufacturer part number: RAD-34J

      Cross-Mania tip: Fit a new reed block gasket, tighten the screws in a cross pattern to the specified torque and check the carburation after fitting a performance unit.
