Internal combustion engines produce power by producing heat. Bigger internal combustion engines produce more heat. Without heat, your Harley would be a piece of garage art suitable for collecting dust. So embrace heat, it's good for you.
First, your right foot and lower leg are sitting right next to the catalytic converter. Catalytic converters run really really hot by design. Since Harley didn't see fit to properly isolate the high temps from the rider (since the double wall pipes and shielding might make the bike ugly and more expensive to produce), it's up to the customers to break the law and fix the problem the easier way. Swap out the stock headpipes for a catless aftermarket product, and store the original in the attic or basement just in case the authorities start requiring motorcycle emission checks sometime in the future. Then tune the bike so that it runs a
little richer, since a richer mixture will burn a little cooler. It will also run a little better. Then if you still feel a need for more heat reduction, remove the lowers and let more air flow past your foot and leg.
