Helps to keep the tank full.
Some have applied heat reflective foil to the underside of the gas tank.
Adding a full exhaust (no cats), ZSteve's heat shields, silver reflective sheet under the tank, and TechSpec tank grips make heat almost a zero issue for me. Yes my 2008 feels warm when the weather is hot but it is definitely nothing that is unbearable. My thermometer read 110 F yesterday and I felt fine [little warm]. You have a 150+ hp motor between your legs, it is gonna put out some heat, you just have to see what works for you to mitigate the effects.+10
Another thing I might suggest is totally removing the lower fairing foam shields. I did this last summer and the hot air hit my leather boots and lower legs where there is more material to block the heat instead of just one layer of from the knee up. It seriously made the tank cooler.
I have an 09 and the tank is extremely hot in very hot weather, even with the tank grips. I have always felt that the tank heat was worse than the heat on the ankles. A fresh refill helps a lot. At a minimum, you should were jeans or motorcycle pants, never street pants or shorts (for safety and protection against the heat). Much as I don't ride in the rain (unless I get caught), I try not to ride when temperatures are above 85 degrees or below 32 degrees; again, unless I have to. At those temperatures, the fun factor from riding is just not there and riding becomes a chore was than fun.
By the way, heat is just not an issue with the C14. I previous bike was a Suzuki M90 cruiser. In 90 degree weather, riding the bike was miserable, with heat coming from the engine and road. Other bikers look cool when they are riding in the heat but it is not for me.
Tank was completely full...i'm basically of the opinion that if the bike is going to burn me then the dealership get's to reverse the transaction and sell me another bike.
Aside from ME spending a ton of money on things to fix a problem that seems to be a fundamental flaw, i suppose i have no other recourse.
