my plug picture

Hey guys

what do you think about my plug color?

Now on my kx 250 01 i have change 160 main for 158 and i drop my needle at the first notch, slow jet (pilot) stock and air screw at 3 turn out. i think that the bike run very good at low and high rpm...but at low rpm my bike spooge a little bit and i have black fuel on the plug thread.

what i can change....pilot or one smaller needle?
and when i turn the air screw i dont see any change...

Looks good to me, nice even color.

well Your Plug looks fine, but 3 turns out on the pilot tells me that you need a leaner pilot (smaller pilot #)
