I cut the thread so that it is easier to post a photo for everyone's input. Also, it is cheaper to waste the plug than buy a quality reader. I can agree that more oil in the mix will help lube and reduce temperatures caused by friction, I would also be leaning out the jetting by reduceing the fuel, and perhaps causing a too lean condition.
Again Rich is correct in his statement that my method of measurement is not relevent to anything but to other readings taken the same way. In my case that is relating the temperature readings to riding conditions (altitude, temp, humidity, engine load, etc...) and to another bike being read at the same time with the same conditions. This A/B compairison so far only tells me that my 220 runs warmer than my bud's 200 under exact same riding conditions. He uses a different race gas, oil, coolant, and engine mods. So far, no one has voiced an opinion that my operating temperatures and subsiquent plug read from a day's ride is indicitive of any harmful condition. That is my main concern, to first do no harm to my bike in a quest to discover all of it's potential. Even then, I'm not too worried about replacing parts that I might damage while discovering the KDX optimal configuration but I sure don't want to have to push this out of the woods due to a catistrauphic failure if I don't have to either.
