I've got the 09, and the heat was unbearable! Bought a set of Zteve's foam inserts a couple weeks ago and it has completely taken care of the problem.
I have always thought my bike ran hotter than normal since the fans would kick on almost immediately when stopped, even in mild weather. I worried that Zteve's inserts might hinder the evacuation of heat from the motor, but I think it's quite the opposite. The fans are not coming on as often now and I'm completely happy. It was 102 here in Houston that last few days, and no problems at all!
