Have you cleaned your air filter??? Rings could be getting a little worn too, my 200s loads up like that when we go out and just cruise around, as soon as I'm done with my 200x I'm tearing into that. Does it smoke??

if i'm not mistaken. the plug will tell you about 6 - 8 different types of fouling.
the dry, black, powdery kind of soot is weak eletrical related (poor - weak spark).
