    Well today i was riding around town and when i got home from my ride i noticed that i had a oil/fuel leak coming from the spark plug hole. The oil was dried on the top of the head cylinder.

    I checked to see if the spark plug was loose but it wasn't, when i took the plug out it was coated in oil, dry with wet patches.

    The bike is running on the 2nd notch from the top on the needle in the carb
    and i'm using a 16:1 oil/fuel ratio as its a new motor.

    Does anyone know what i'm doing wrong?:-/

    air quality, air temp, and where you are in the world will make engines run different.
    so whatever notch on the slide works for one person, it may not work for another due to where they live.

    check the little washer on the spark plug threads. These washers and made to seal the top of the plug to the head. if that washers is cheaply made, it will leak. if you are using the spark plug that came with your kit (not an ngk) i would toss it and get a good ngk plug.
