Spot heat
ok, so a few days ago I had the misfortune of 30+ miles of shitty traffic in a hot day on my 2013 FLHTK. it went quite well except that my right leg calf experienced a quasi-burn (it was a bit reddish, no big deal, completely normal the other day). but that got me thinking, why on earth heat concentrates on that spot and what can be done to get rid of it.
bike is already de-catted (not that I think it matters, cat was behind that spot IIRC) and re-mapped (by yours truly using a 'tts' dongle) - it does not run lean at low rpm, quite the contrary runs a bit rich, and that plus the kind of gas we run here in BR means 'less heat' - overall there is zero disconfort riding slow in heat except for that spot... and thats only when wearing skinny jeans (dont judge!).
ideas?

Is the EITMS system activated?
It shuts down the rear cylinder when the engine get too hot while idling.
You can activate it by tuning on the ignition and run switch and then rolling the throttle forward until the cruise light blinks green.

hmmm not the head per se, but that 'bend' the rear exhaust makes forward on the 2009+... that's probably it.
I never use EITMS... duh forgot to try that... might do the trick!
and/or some pipe wrap around that area should help too.
thanks!!

I get stuck in traffic on a regular basis. Not sure if this is it for you or not but I have noticed similar issues when the wind is blowing left to right. It can blow across the cylinders and hit the inside of your right leg. I don't know how the guys with cylinder cooling fans stand it.
Highway pegs and front brake instead of rear help a little bit in traffic. I have also seen threads that people talk about taking the heat deflector off the left side only.

There was a thread a 2 weeks ago. Theres a thermostat in the oil cooler that is probably bad or not opening sometimes. With his help and the piece that he sold me it has made my bike cooler and runs better in hot weather

I also get a hot feeling on the right calf even while riding at speed. My guess was radiant heat for the chrome exhaust. When to the black painted H-D exhaust heat shields and found it much better. Ceramic coating would really help but I'm too cheap to go that route.

that's what i'm thinking exactly... and for some odd reason that part of the exhaust dos not have an 'inner' shield like the sportster do. will try adding some pipe wrap there for starters... and check that thermostat suggested before, did not even know it existed... but that's probably OK as the engine itself does not show any signs of overheating (im constantly logging it to improve the tune and engine temp shows 150 or less always).
