    Hi folks

    I have a 2004 570 SMR with the Mikuni TMR41 carb and it runs too rich. But I don‘t know why exactly. Can anyone recommend a solid base jetting?

    My actual setting is:
    Main jet: 170
    Needle: 10E1-52 / clip on second notch
    Needle jet: Original (Forgot to check :P)
    Idle jet: 25

    With this setting the spark plug is jet-black. Almost can‘t start the bike with hot engine.

    Open air-filter housing (little holes). Cylinder and piston are from the NOX. Little bit more compression.
