    What jetting do you guys have on sm 125 with tmx38?
    Im looking to buy a bigger idle jet cause it seems to be lean at low rpm.

    Its not the rpm but the throttle position that determines what circuit to jet.

    idle to 1/8 is the pilot
    1/8 to 3/4 is the needle
    3/4 to full throttle is the main jet

    adjust one circuit at a time because they overlap and each time you adjust the needle or the pilot re-adjust the air screw
