Installed power x wing on my 06 kx 250 f and had problems starting it when I finally got it running throttle was unresponsive sputtering ran really bad this thing is a waste of money its sitting on my work bench now as a paper weight
The product seems to do what it advertises. I did notice an increase in throttle response off idle. On a YZ250X, it seemed to make the pilot circuit & needle operate somewhat leaner, maybe similar to a 1/4-1/2 clip needle change.
Installation wasn’t too bad; remove rear carb air boot by swinging rear sub-frame upward. Place unit in carb, then reassemble. Start bike up and ride. The changes are small, but I would suggest. If you don’t notice slight changes or always ride throttle full open, then this product probably isn’t for you.
Easy to install and great fit
Paired this with Boyesen Power reeds and that is the best thing I ever put on my '03 Yz85. It made it a little more ridable but never restricted power through the mid and top.
Here is the listed benefits of the product:
-NCREASED AIRFLOW PERFORMANCE
-Increases horsepower and torque in 2 and 4 stroke bikes
-AERODYNAMIC design maximizes velocity generation and power gain
-WING CHANNEL minimizes disturbance at needle jet without affecting jetting curve
