  Boyesen Rad Valve

  John in CA

  The best upgrade

  I put this on my yz250 and when on the track I was blown away with the power and response. More low end and more over rev and crisp throttle response. I dropped the main jet one size to a 175 and pilot jet one size to a 48. It also has a pro circuit pipe...The bike feels like a whole new bike, jumps I had to click into 4th can be done easily in 3rd now with throttle to spair. If I could give it 10 stars I would.

  Tusk Carburetor Vent Line

  Matthew in MD

  Good Option

  Worked well to replace vent lines on carburetor rebuild for 2006 KX450F. The red color is truly red - not the clearish pink you might see on some bikes.

  JD Jetting Jet Kit

  Improved throttle

  Easy to install, great instructions with recommended jetting for mods. Adds a nice pep and better throttle response. Drz400.
