That's white alright. Seems it was running lean while on the main jet more? I'd go back to the stock main, then mess with the needle clip position if necessary.
The pilot jet is only going to effect about the first 1/8 of throttle -- just off idle. If adjusting the pilot screw isn't effective within 2 turns out, downsize. If it isn't effective at all, upsize. I think that's how it goes? Hey, it's been a while. ;)
The main will have a significant effect starting at about half throttle. It's easiest to test the main by getting the engine warm, swap in a new plug, then go for a WFO rip -- pull the clutch in & hold the kill button in, then stop and check the plug.
Once the pilot & main are set, you can tweak the needle clip for best "feel" -- the bike should not stumble (rich) or feel like it's gasping for air (lean) when rolling the throttle open.
My '06 is stock and runs well (idles, pulls cleanly) at a few hundred feet above sea level. This time around (I had an '02 prior to my '06) I've started running Bel-Ray H1R instead of Yamalube 2R. The Bel-Ray seems to be burning better at lower revs/temps (woods riding). I always run 32:1.
