I have a new Heritage Classic. I noticed while riding this past week that the speedo had just a little bit of fog in the center of it. This appeared after riding a few miles. Outside Temp was low 50. Later that afternoon after temp got about 70 the fog disappeared. Can any of you tell me what might be causing this? And is there anyway to prevent this from happening?

 

Don't know what causes it but they all do it. My worst one is the fuel gauge. H-D will likely tell you it is normal.

 

They are not airtight.Condensation can build up from inside warmer temps and outside cooler temps..As outside air begins to warm up.it dries up condensation..My old speedo never accumulates this as it is a mechanical one that is "very "open ...just guessing..
