This gauge is useless! Im in Florida and it is always in the 100's+
Change out for an oil temp gauge when you get a chance!

air temp gauge
The gauge was excellent for one thing. Rip it out and installed a oil temperature gauge in its place. This will give you good information how hot your bike engine is. I noticed that around 235 degrees my 09 Ultra kicks into to parade mode. Another thing to keep in mind is that the syntheic oils break down around the 290 to 300 degree range which means that the oil is no longer lubing your engine.

Relocated mine to below the fairing. Now it's sometimes pretty accurate and sometimes 5-10 degrees below actual air temp. Go figure.

I actually replaced my temp gauge with a black faced digital with 1/2" tall red letters so it is easy to read, blends in pretty well with the other gauges, not an exact match, but OK. The gauge I used is water proof, shock resistant, goes from -25* to 250*, made for walk in style coolers, etc. Made to be used outside or in the elements. Only downfall, it is 6VDC, so you have to have a 12VDC to 6VDC reducer for it to work. Had an electrical buddy that made this for me. Mine works great, is accurate within 2* and looks good doing it. Mounted the probe between the forks, just behind the chrome cover below the headlight, outa site, protected, and not exposed to excessive temps from anything.

Now y'all got me to thinking. I want to replace the air temp gauge with something really different. What do you call those horizon things instrument pilots use? It would let me know whether I'm still upright or not.

Absolutey true. And who needs to know what the air temperature when you're on a motorcycle. You're already outside, you can tell if it's hot, cold or in between. But, it was something cheap to balance out the gauge pattern. And it is something to look at when riding. No harm done.
