...oh well, I guess as long as they work. Guess I've been lucky with mine. I had no idea it was a problem of such pandemic proportion!

 

I have owned many foreign bikes and never had an issue with water in any gauge. As for them exploding or shattering at high temps.........well I'm pulling the B.S. card on that one. This should be a no brainer fix by HD.

 

my yamaha doesn't collect water. I think it is because HD uses metal housings on the speedo's and the Metrics have plastic housings.

 

* copied from another thread:

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?
