BOYESEN Rad Reed valve system for KAWASAKI KX 500 1987-2004

BOYESEN offers this reed valve block for KAWASAKI KX 500 1987-2004. 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 on your KAWASAKI KX 500?

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
