    wow- better power everywhere

    I purchased a rad valve not having any major expectations. I was certainly surprised at how much more power and cleaner response my ktm 250 engine made. Power started a bit lower than usual and ran through to an incredible midrange and top end over rev. I had to screw in the yellow power valve adjuster almost all the way to keep the power linear. Jets up a bit better do and it feels like the motor revs much more freely. No need for head mods, this is enough. Perfect smooth linear power. love it!

    Reed block dependent

    If you don't have the 250SX or Boyesen reed cage, then this product will not fit. Other than that, these are great and made it run a bit better in the midrange.

    Great Product Great service

    Pretty easy installation, great instructions. I put an exaust and k/n filter, and re-jetted. I had issues with the quad either dying or bogging down and sputtering when punching the throttle. This was the perfect solution.
