Mine seems to run hot as well, hotter than my friends 2011 for sure. In slow traffic temp will rise quickly to the point where the fan kicks in but even on hot days on tight trails it has never run up into the last two bars. I may change the coolant to see if I can cool the bike a bit with a bit more water in the mix. Also check you coolant level, I was surprised to see the bottom hose connection on the overflow tank has a slow weeping leak, it being a brand new bike and all. I did have the bike back fire and stall in the heat once. Likely this is also when my TB started to work loose, a lean condition in the heat I guess. I've since added a FMF pipe and Akro map. No more back firing and TB hasn't moved since.
