Question '18 Heritage 114 Engine & Head Temps

A guy on YouTube has a couple of videos talking about what he thinks are elevated engine and head temperatures.

The first screen grab shows the temperatures with his feet on the footboards.

The second screen grab shows the temperatures with his feet on the highway pegs.

He is asking his audience if what he is experiencing is normal or not. What do y'all think?

FYI, ambient air temperature is ~65°F and he is cruising at ~80 MPH (~3,000 RPM).

Yep, my Roadglide is right about at those numbers. Really hot days, I've been at 360 degree head temps with 330 engine temps. Usually 30 degrees between the two.

I've also noticed the variances in temps verses where my feet are. And I always run cooler with my feet on the floorboards. I assume it's because the wind gets channeled towards the motor. Feet on highway pegs actually block wind.

I know that my Roadglide is 30 degrees hotter with my lower fairings attached than when I take them off.

I am not surprised. You should see the temperature difference if you add soft lowers. Big change with the lowers but you'd typically take them off in the summer. As far is the difference he is seeing regarding where his feet are, I don't think it is of any concern.

Perfectly normal.
Size 14 boots out on forward controls block the cool air to engine, It's why I switched to a mid mount bike for cooler running.

The M8 take their temps from closer to the exhaust than the TC's so they do read hotter but they really aren't.

I don't have highway pegs so I'm not worried.

I don't have a temperature guage, so I'm not worried too. I have the memory of a goldfish, so I won't remember to worry about it either.

I made the mistake of getting an oil temp gauge for my 07 Ultra many years ago and all I did was look at it and worry. I have had several bikes since then, never installed a gauge or looked at the Power Vision gauges, and never worried about heat again and never had a heat related issue on any of them.

Based on what y'all are saying, I just posted a comment on his video that he should just ride it like he stole it.

In addition, I should have suggested that he remove that Power Vision and throw it in a drawer!
