    JD jet kit for 2019 300XC

    Put a JD jet kit in my son’s 250xc & it made a huge difference. Actually ordered this one from Rocky Mtn before I even picked up my 2019 XC 300

    aftermarket carb

    Received a clean new carb in the box. The carb only needed minor adjustments and the bike is running like a dream. Would defiantly recommend QA carbs to anyone looking for a cheap reliable alternative.

    Great value. Saves lots of guess work

    I bought a used bike with almost no use on it, but previous owner had rejetted. I had no way of knowing what needle was in it, so I bought the JD kit. Bike runs crazy better now.
