      The BOYESEN BOYRAD-33J reed valve block is designed for FANTIC XE 125, XX 125 and YAMAHA YZ 125 from 2005 to 2021. On a two-stroke, the reed valve block sits between the carburettor and the engine. Its petals open under suction and close again as soon as the pressure reverses: the engine's pick-up and power depend on how quickly they react and how much air gets through.

      Specifications

      • Brand: BOYESEN
      • Manufacturer part number: BOYRAD-33J
      • Weight: 280 g

      Who is it for?

      • Original cage damaged, or petals wearing out again and again.
      • You want more pick-up and response when you open the throttle.

      Good to know

      Check the petals at every piston change and replace them as soon as a tip is chipped.

      Fitting tips

      1. Clean the gasket face of the cylinder or crankcase.
      2. Fit the reed valve block with a new gasket, petals facing the engine.
      3. Tighten the screws in a criss-cross pattern to the recommended torque.
      4. Check the carburation and the colour of the spark plug after the first few rides.

      Frequently asked questions

      Do I need to change the jetting?
