My idea adds nothing to the HD bottom line. No doubt Harley has a meeting to discuss your idea on their agenda. Performance Clear Gauges Cartridge as a 2021 catalogue item, will be standard on the 2023 bikes. My Kury wiper idea would void the warranty for the entire bike ~"Unauthorized gauge moisture removal caused the sumping problem, your warranty is void." CVO bikes will require a special CVO Screamin' Eagle gauges cartridge that will cost $99.50.
Or they could just use the same very well known tech knowledge that the auto industry has used about forever to have fog free gauges...
I think they could go back and use the 2009 and earlier Harley Technology. My 2003 Fatboy gage is perfect, no fogging or runs. My wire's 2009 Heritage with over 100,000 miles on it gage is perfect.
My 13 CVO King there are moisture runs in it, and bad fogging cant hardly read the odometer. My 19 Speedometer has runs in it and slight fogging. My 15 and my 17 had gages replaced as will my 19.
13 waited to fogging until it was 6 months out of warranty.
