BOYESEN Power Wing - YZ 85 PW-10

If you're running a YZ 85, you know that extracting every last horsepower matters—especially when competition is tight. The BOYESEN Power Wing optimizes your engine's breathing efficiency by fine-tuning fuel atomization at the needle jet, delivering measurable gains in horsepower and torque without requiring carburetor rejetting. This is precision engineering that translates directly to throttle response and mid-range power.

The aerodynamic wing channel design minimizes turbulence where it counts most, allowing fuel velocity to peak at precisely the right moment in the combustion cycle. Installation takes minutes thanks to the precision-fit design, and you'll feel the difference immediately on the track.
