The two pictures are two different plugs, right? The "pink" one has a good color to it... if you call it "tan" that's about the shade you want all over the porcelain... the hue will vary depending on the kind of fuel you run (what fuel do you run?). The area we can see in the photo points to part throttle mixture. The other "white" plug looks too lean in this same area. From the second picture, it appears to me that timing is about right where you want it with the "blue" line about at or just past the apex of the bend. Also from the second picture it looks like you are rich at idle based on the soot on the threads...

Carb or FI? The two plugs you show are quite different... which cylinders did they come from?

Hope some of this helps...
