Title: Guage Glass Cleaning
Post by: 17 StreetGlide CVO on November 28, 2019, 04:36:03 AM
Happy Thanksgiving to all. How difficult is it to clean the inside glass on the gauges? Have some light streaking from moisture driving me nuts.

Do not know of any way to do this.  This is a known problem on Harley gauges.  Harley has no fix for it.  My gauges were replaced under warranty & the new gauges did the same thing.  Harley seems to be oblivious to certain problems - gauge streaking is one of them.

I have had gages replaced on many CVO's due to streaking under warranty.  This problem has been on going since at least 2012, had one replaced in my skunk, my 13 King did not streak until it was out of warranty.  My 15 had the gages replaced twice, my 17 twice, my 18 once and my 19 now needs it.

No fix.  Had mine replaced several times under warranty, replacements do the same.   It's actually not water/condensation, but an oily coating they put on the inside of the glass to stop the condensation that was a problem on pre-Rushmore models.

Had the same problem with my 16. Was going to replace with stock gauges but didn't want the same problem again so replaced them with Dakota digital and love them. Good luck

Goes back much longer than 2012 or 16.  Not knowing how (or not being willing to spend what little difference it would take to accomplish what they actually have to know) to assemble a proper weather tight instrument for motorcycles has been an issue for Harley for as long as I can remember.

I can recall at least two Tour Glides and one FXRT that had gauges that tried (and failed) to wash themselves from the inside out; and we never really paid attention to such things then.  So it had to be at least as common as it is today.

I don't remember seeing the problem with Road King or Softail or Dyna instruments.  Then again none of my Road Kings ever kept their stock instrument for very long and the aftermarket seems to do this better.  So the issue might be going on there too and I just never noticed.  Would be interesting to know if it's just Glide instruments Mother Harley has had issues with though. 

Maybe Harley needs to buy touring gauges from boat builders....

Gauges on my 2010 CVO SG did the same thing.

I cleaned the small gauges on my SEEG. They were so bad, I was going to order new ones so I had nothing to lose by trying.  Took the gauges out and carefully worked around the outside of the ring, prying it up.  Finally got it to where I could remove the ring and glass.  Took some oven glass top cleaner (similar to soft scrub) and removed all the cracked film from the glass.  Cleaned it up real good with glass cleaner then reinstalled the ring and glass...pushing down the edges of the ring and worked around similar to removal.  A small bead of silicone around the edge to make it waterproof.  Let em dry then put them back into fairing.  I could see the edges where I bent them (unacceptable to me) so I went to Napa and got some thick o-rings that fit around the gauges and when pushed all the way in against the inner fairing they are not noticeable but hide the edges of the rings.  The glass is perfectly clear and have not had a single issue in the five years since.

The speedo on my 18 RG is showing the signs of residue so I currently have a new one on order under warranty. If or when it happens again I'll probably go with the Dakota Digitals since it will be on my dime and I have had a few excellent experiences with them in the past and their new Touring gauges are bad azz.

The GaugeMods guy gets them apart and changes the face of the gauge for a resonable price so he could probably help on disassembly to clean the gauge lens. Maybe he would even clean them for a fee?
