try the airflow kit that came standard on the 2007 onwards model. it directs heat away from the inside of your thigh. mine nearly burned off early on. ~£20 from a dealer, and problem sorted for hot air
Buellparts.net has a "rider comfort kit" that might be of interest to you. I do not have it, and I do not know if it fits anything other than the XP model as stated. Check it out:
Also, several other forums have pictures of mods people have done for the heat issue. I put a little foil tape in a few select spots on mine and it really reduced the heat. Nothing that I feel would compromise the cooling ability, and it certainly did not eliminate the problem.
