BOYESEN Rad Valve System - Blaster for YAMAHA YFS 200 BLASTER 2WD 1990-2007

BOYESEN offers this reed valve block for YAMAHA YFS 200 BLASTER 2WD 1990-2007. 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 YAMAHA YFS 200 BLASTER 2WD?

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-35A

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.
