MY speedo and tach both fog on my 2018 Lowrider. The fogging starts when riding or parked when the sun is shining. The speedo fogs up more than the tach but the tach does fog some. In fact the speedo has so much moisture that it actually runs in the bottom third of the speedo. The tach just fogs a bit in the bottom third of the tach.

Oh, my 2016 FXDL has the condensation prob too. So much so, that it's impossible to read the odometer/gear #/miles to empty/etc.

Gas vapours
Did you ever determine if fuel vapours were causing residue? responsible
I want this issue to remain alive because it is so infuriating that it can't/won't be solved.
But here are some of my facts as I investigate this: 2018 FLCHS
1) I don't readily discount the theory that gas vapors are at play here. The "moisture" definitely leaves behind a residue that suggests that it COULD be gas. Also, I was removing my console last night and there was a strong smell of gasoline from underneath the console. So, while I can't prove the theory - honestly, I can't structure a scenario where it is true - I can't completely eliminate it either.
2) Here is what is hard for me to explain......while I ride in all conditions moisture will form under the glass of the speedo. If I park the bike either in my garage, or in the sunlight, the moisture almost immediately begins to go away. Then, when I ride again, it returns. That's not the way this should act if it was moisture from the air. Additionally, it forms in the exact same spot every time. If the coolness of the air while riding is enough to condense the humidity in the air, the moisture should become worse once the bike is in the "cool" confines of my garage....not go away. Therefore, I also cannot completely rule out the theory that this is the result of an interaction of some glue or seal that is used inside the speedo.
3) If the moisture can get in....it should be able to get out when it is heated up. The hotter it get, the more it should leave the speedo. That doesn't appear to be the case. The speedo I have now has never been in the rain, and it has been protected when I wash the bike (which has been about 2x since the speedo was replaced). And yet, it condenses in EXACTLY the identical way that the first one did. That can't be coincidence.
Bottom line: I think we are too quick to label this a moisture issue and are neglecting other causes.
Bottom line 2: HD should be ashamed of themselves and should move out of the U.S. if this is the best they can do. (not really....just frustrated)
