Everything's fine but your jetting.

 

9 times out of 10 a hot running banshee is attributed to lean jetting. I've ridden my bike in the glamis summer heat at 115+ for hours and hours, and it never overheated...

Sounds to me like you're too rich. You should be closer to 162 main and 48 pilot. Yes, running way too rich can case overheating.
