My spark plug is burning yellow... that's right yellow. I have never seen or heard of this... anyone know what is cuasing this and if it may potentially be a problem? I am currently running a DASA intake and exhaust with a 185 main jet and 2 1/2 turns out on the air screw.

the brand of fuel you run will make a pretty big difference on the color of the plug. shell fuel would make mine yellow too.
