V-FORCE V-FORCE 4 Reed valve system - BANSHEE for YAMAHA YFZ 350 BANSHEE 2WD 1988-2007

V-FORCE offers this reed valve block for YAMAHA YFZ 350 BANSHEE 2WD 1988-2007. 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 V-FORCE?

The V-Force reed valve was original equipment on KTM SX two-strokes from 2004 to 2014: a double V with carbon petals for better engine filling.

When should you replace the reeds on your YAMAHA YFZ 350 BANSHEE 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.
