    a jet is a jet to me but it looks great and works the only down fall was that it took a while to ship do to the fact that it was not in stock...

    Pilot jet worked fine

    Bought this for a 2002 KTM 520 EXC. Turned out to be too rich for Colorado Springs, but the part fit fine.

  • Keihin Air Cut-Off Valve Set

    Keihin Air Cut-Off Valve Set

    Perfect

    "SUDCO" Packaged "OE Parts". Perfect fit and price was right. Had some backfire issues the instant I "rolled off throttle", this kit should take care of that issue. 16 years made the stock Air Cut-Off Valve parts too stiff/brittle and it wasn't working right anymore. Installation is easy enough after you remove the Plastics, Seat, and Gas Tank, then it's just 2 screws to pop the cover off the Air Cut-Off Valve, clean up everything, replace the little gasket/o-ring, the cut-off valve and spring, put on the cover and 2 screws, the gas tank, seat, plastics and you are done in about 15 minutes of work.

    Initially would have rated poorly due to OnTrac

    OnTrac failed to deliver my original order of jets. Was most upset over the fact that I was home all day, got email that package was delivered at 4:46PM yet there was nothing at my door. Contacted OnTrac and got zero response or resolution from them. Contacted Rocky Mtn. and they immediately sent another order for free. Great customer service.
