I bought a new 04 KX125 in September. I have been fouling 1 plug per tank of gas. This is what I have done so far, I reduced the mix to 40:1, I turned the air screw back 3 turns from snug(the book recommends 2 1/2 from snug). Also when I remove a fouled plug it is very oiley and black.QKENUF4U said:hey
