    I have always had a boggy mid throttle
    Opened carb and discovered
    Main Jet 132
    Pilot 42
    Leak 68
    Needle Clip 3

    132??? is that correct?

    The bike needs to be rejettet and breathe more from stock.

    First of all you have open up/cut the airbox,
    Remove the air filter backfire screen
    Drill the exhaust's baffle or change to an aftermarket can.

    Then for jetting:
    165-170 main
    stock or 45 pilot
    JD red needle or NCVS needle on 4# from top.

    All theese depend to your elevation and temperture though.

    The best way to go is buy the JD kit for the x.
    It has everything with perfect directions.
