Went for the ride and the temps were about 48' with no wind. When cruising around with less than half throttle the bike runs well and throttle response is excellent but when I start to go to WOT it revs fine from 2k up to 6k then it stumbles till around 8k then it revs fine all the way to redline just fine. Not sure if it is lean or fat.

if that spot got better when the temps went down, that means it was rich. Try taking a washer off the needles when it's hot out. That's also right where the needles/main jet interact. You might want to try playing around with other main jet/needle combinations. Have you tried other mains? Like is that 105 the hardest pulling jet you tried?
