BOYESEN Pro Series Reed Petals for OEM reed valve for KAWASAKI KX 65 and SUZUKI RM 65 2000-2022

On KAWASAKI KX 65 and SUZUKI RM 65 from 2000 to 2022, the BOYESEN Pro Series BOYPRO-139 set of reed petals fits in place of the original part. The reeds control the intake of a two-stroke engine. Over the hours, the petals tire, split or fray at the tips: the engine responds less well to the throttle and is harder to start.

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.

When to replace it?

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.
