I have been having an issue with engine heat during these long hot summer days in North TX.
A large part of the heat problem is that MoCo tunes the engine with a very lean AFR (Air-Fuel Ratio) to reduce emissions and improve MPG to satisfy the EPA and state air pollution agencies. The cure for this is a fuel management device (such as RevPerf's EMS, TTS Mastertune, Power Commander, etc.) to enrich (i.e., a
lower number, like 13.5 to 1) the AFR. Another contributor to the heat problem is the catalytic converter ("cat" or CC) in the exhaust system. Cats
have to get hot to work, so they're built to restrict exhaust flow. The cats get way hot, and on a motorcycle it's right under us. That's why there is so much talk here and elsewhere about getting rid of the cat, whether by replacing the head pipe, cutting out the cat from the stock pipes, or, in bikes with cats in the mufflers, fixing it there. Here's a link with lots of info about removing cats:
