    Jetting and a few other questions for a 07 150R

    by Denton » Sat Feb 14, 2015 3:08 pm

    So here is what I am working with jet wise.
    Starter jet 68

    Pilot Screw 2-1/4 turns

    Slow jet 42

    Main jet 140

    Jet needle NHNT

    Jet needle clip 3

    Leak jet 60 has a good squirt about 5.5ft

    My riding will mostly be from 500ft to 1000ft. At about 70 to 100 degrees. Most of the time being 80 to 90.
    So I read that the 07 jetting specs are trash and the later jets are the way to go
    So according to the book I need
    Starter jet Cant find

    Pilot Screw 2 turns

    Slow jet 38

    Main jet 135

    Jet needle NMQS

    Jet needle clip 3

    Leak jet Cant find

    To keep in mind there is a Pro Circuit T-5 Slip-On Exhaust. Which I believe was put on to quiet the bike down some. Does this new jetting specs look right?
