      The BOYESEN Pro Series BOYPRO-114 set of reed petals is designed for KTM EXC 250, EXC 300, EXC 380, SX 250, SX 380 from 1999 to 2003. In a two-stroke, the petals of the reed valve block open to let the mixture into the crankcase, then close to stop it coming back out. Tired or chipped petals don't close properly: the engine loses bottom end and sharpness.

      Key features

      • Carbon-fibre top petal and fibreglass/epoxy bottom petal: dual-stage operation.
      • Designed to fit the stock reed block.
      • Designed for Boyesen reed blocks.
      • Made in the USA.

      Specifications

      • Manufacturer part number: BOYPRO-114
      • EAN code: 804429005673

      When to replace it?

      • Petal tips chipped, split or frayed.
      • Petals no longer sitting flat on the cage (visible gap).
      • Weak pick-up at low revs, hard starting.

      Inspect the petals at least once a season and at every piston change; replace them as soon as a tip is damaged.

      Fitting tips

      1. Remove the reed valve block and clean the cage.
      2. Fit the petals the right way round and tighten the petal screws with threadlocker to the recommended torque.
      3. Check that the petals sit flat on the cage before refitting.
      4. Refit with a new reed block gasket.

      Frequently asked questions

      Do I need to re-jet?
      Usually not on a well-tuned engine; check the colour of the spark plug after the first few rides.
