My speedo has fogged up too. Normally it doesn't rain in Southern California, and when it does the bike sometimes goes inside. Last time it rained (which was not nearly enough to help our drought) the bike was outside.
In the past when this happens the fog clears up after a day or two of being in the sun. It's been a few weeks now, and it still has not cleared up. This prompted me to remove the instrument from the bike. Upon inversion, I was able to dump a suppressing amount of water out from the illumination bulb hole. I left the speedo in the sun for 3 more days and it's still foggy.
I think this thing needs to get opened up to air out. I figured the black trim ring around the face was threaded, but it seems like it is crimped on. Can anyone confirm this? What is the best way to open one of these assemblies?

First off, the reset button isn't sealed. There's supposed to be a rubber cover over it that seals out moisture. From the looks of it, it's rotted away and fallen of long ago.
That needs to be replaced.
Supporting the outer edge of the bezel does work to prevent distortion. And, yes, it is crimped on. Too bad it's not screwed together. Wouldn't that be nice?
