Temp Gauge question

Post by vizulefllry »

In the last few rides I've had this issue that I'm hoping someone can help me with.
I know that if your temp and gas gauges stop working, its the 7V regulator.
But I'm trying to figure out what this is...

Prior to a few rides ago, when I started my bike and left it warm up, I'd see the temp gauge move up to about 1/4. Then when I was on the road and getting some nice air going it would usually go down a bit.
The last few rides it was kind of the opposite. When I'm warming up, or sitting at stop lights, even on a nice September 80 degree day, the temp gauge is barely off of 0. But when I'm running on the highway at say 70 for a while, it moves up some.
One thing to note is that the fan is not running all the time. If it was, this might make sense.

Could this be the 7V Regulator? Or is the thermostat always open?

Of course my main concern is that there isn't something faulty that causes an overheat in the future.
Any help is greatly appreciated. I'm no mechanic, but I'm pretty handy. So hopefully this is an easy fix (or not a concern) and it keeps me on the road and out of the garage (and my wallet happy).

Thank you!

If your fuel gauge is working normally that pretty well rules out the 7 volt regulator, and likely your temperature gauge is telling the truth.

That being the case, it sounds like your thermostat is stuck "open" and not letting the engine warm up to normal temperatures.
