Any of the experts out there have any comments on the idea of adding an oil temp sender to the air temp gauge?? of course you would need to know metric for it to work ... Ive never been inside my fairing so I dont know what the back of the air temp gauge looks like or even if it has an external sender or built in
The air temp gauge does have a remote sensor. They used to be located inside the fairing clipped to the left side fairing bracket, which of course was a really genius idea. As the heat from the headlight and the sun cranked up the temperatures inside the fairing, the gauge would of course read nothing close to the true ambient air temperature. I fixed mine years ago by extending the wire for the sensor and mounting it under the steering head bracket and out in the actual air flow. Still isn't super accurate, but at least it's now prettty close. Still a dumb thing to put on a motorcycle though. I forget which year they did it, but Harley eventually saw the light and moved the sensor outside the fairing, to the left side of the frame at the steering head area. It's still not directly in the air flow at that location, but it's much better than it was before.
I imagine if someone wanted to take the time to rig up a oil temp sending unit and some simple circuitry to match the resistance to the gauge, they could make it work. However the scale would be off, and it would still say air temp on the face of the gauge. And when you got done making all those mods, you'd still have a very cheap gauge that is reporting information of dubious value.
Why not just take two of the four gauges, you choose which ones, and throw them as far into the weeds as you can. I vote for the air temp and voltage gauges. Then fill those two holes in the fairing with something useful, like some nice tweeters for your sound system. Or maybe you could create some fresh air ducts and adjustable vents, like some other brands have standard.
