got it too, i agree that it has nothing to do with rain or washing and the seal on top of the speedo, but the problem is caused by the humidity and temperature variance within the speedo affected by those 3 little vent holes in the bottom of the speedo casing.
It is like a wet jar placed upside down to dry (it won`t), unless it is turned open end up and the moisture or humidity difference is allowed to evaporate up into the outside air.
I have never had this problem in any of my previous bikes and it makes a beautiful bike look like crap, imho.
I am going to try the following to try to fix it:
1. pull the speedo, without disassembling it, slowly heat it with a heat gun upside down so the vent holes are on top. hopefully the internal moisture will evaporate out those tine vents.
2. if that does not work, maybe rig some Deliquescent materials that will suck the moisture out of the vent holes
3. if that dos not work, try to rig new vents that work properly.
i can not understand why HD has not fixed, or provided methods of dealing with this problem, since it is their engineering FAIL.
Last question to others with this problem is: do aftermarket or non OEM speedos suffer from this crappy engineering fail?
It all boils down to the gauge not being hermetically sealed. If it was, then there would never be an issue. I really wonder if there is a reason they haven't done this...besides increased cost...
kinda sad that i pay over $10K for a HD with this obvious company engineering fail, and i have bought other bikes for less than $500 that never had moisture in dials, just saying that maybe HD should invest a small amount of effort to fix this problem, looks like $hit when you pull into a show and shine , work an hour to get her shiny then the moisture in the speedo shows up....
