Steaming
« on: November 11, 2009, 11:58:17 AM »
A question for Trolle / Suecanada or our northern riders. Just got back from makeing the most of a cold but dry sunny day and for the first time not only the tacho but the speedo as well have steamed up.I know all about the tacho doing this and thought i had cured it during the summer but the speedo has never done it before.... is it normal the air temperature was about 3 deg C.
I put the question here as i dare say this could happen with any bike.
Lou.......oh i wish i was in Dixie(well it will be warmer) i would still be able to count to 10
Ask questions later

My LS tach does this frequently when it is cooler outside.   To a lesser degree the speedo will also.    The light bulbs inside the instruments generate just enough heat to cause condensation to form on the inner face of the lenses, but not enough heat for the water to evaporate and/or it cannot easily get out.

Some folks have suggested different bulbs can help - but one has to be careful to not go too high in wattage or the bubls heat can be excessive and melt things.   Some have suggested drilling tiny holes near the top of the speed but where the rubber lib would keep rain water, etc. from getting inside.   I haven't tried this/donm't know how well it would work.

This time of year it is a common occurrence in our area.   Yesterday was quite warm @ midday (15C =above normal for this time or year), but by 7PM it was more normal (and dark of course) around 4C.   My Kawasaki's instruments are seemingly impervious to this problem, but the R65 dials do fog up.

I agree, when I lived in Chicago, the indicators would 'fog-up' a bit in cold weather, without having been exposed to rain, or water from washing .

I put a flood lamp a few feet away from the instrument cluster for an hour or so, and the moisture disappeared .

Once your riding season is over, and the bike is parked, you could remove the indicators, and put them in your oven, with the light on, I've done this a few times, used a 100 watt lamp, and the temperature would get up to 100-110 F. (38-43C.) in a few hours .

Both of mine get foggy in damp weather and/or temp below 15C ~ 60F as do the voltmeter and clock. When it gets too annoying I put the instruments into the oven and set it to 100c ~ 212F which helps for a while.
