Air temp gauge fix?

Check the catalog. There is an air temp gauge that you can mount to your handlebar controls. I have the Dakota Digital gauge package, and air temp isn't a choice. Like you, I missed knowing just how cold or hot it was. So the handlebar gauge. Pretty accurate except when left sitting in the sun.

My watch has an air temperature gauge. Unfortunately, if it's sitting in the sun while you are riding its just about as accurate as the temp gauge on my Harley. SJ Ron

I know I'm going to get a lot of flames but I really miss having a functioning air temp gauge on my 10 Limited. I did a little searching and couldn't find anything. I was wondering if anyone has heard of a fix by moving the temp probe outside of the fairing? My GL1800 had the probe under the fairing above the front tire. It would show temp changes every few seconds.
More curious than anything.
I know about people replacing it with an oil temp gauge. That's not what I'm looking for. Besides no where I've found said that above this oil temp you should pull over and let it cool down. So what's the point?

Alls you have to do is google the question. Works much better than search engine on the forum.
Here is your answer.

I would think the oil temp information is more important than air temp.
I replaced my air temp guage with the H-D oil temp guage but mounted the sensor in the oil pan rather than the oil line as the instructions show.
I had the H-D air temp gauge that can be mounted on the handle bar. The oil fill in the guage begins to break down and begins to look like brown silt (see photo). I tossed that and bought the Dakota air temp guage.

The probe is not in the fairing. It reads the air in the intake. It operates off the same sensor as the ECM reading intake temp. That is why it is always higher than should be. Nothing you can do. This is the reason myself and many others take it out and install oil temp gauge.

I did move my air temp gauge sensor from its original location (inside fairing).
My sensor resembled a small, "off white" colored cube. I extended the wires and quick-tied it so it was barely peeking out from under the triple tree. It appeared to be sealed and weather tight.
I find the air temp gauge to read more accurately in its new location.
It worked for me.

I knew that a lot of folks would talk about replacing it with an oil temp gauge. So my question still stands. At what oil temp do you pull over and let it cool down? Everyone talks about the useless air temp and how important the oil temp is but so far I've not found any useful information about oil temp.
Since HD put the darn air temp gauge there I want to use it. There are plenty of times when I was touring that the GL would say 105 or 107 and I knew that I should pull over and cool off. You don't feel the heat with all of that wind blowing and drying the sweat which cools you off. You do get dehydrated in short order though without really noticing it.
