I noticed in this month's AirHeads magazine that some entrepreneurials have 3-D printed and redesigned the flex circuit assemblies that go into the dashpanels on airheads - they are still in the process of getting production going, but I think that I'll try out their product later this winter on my 78 R100. Not sure yet if they'll have an R65 version, but might ask.
Anyhow, it seems like some are still interested in keep the old airheads on the road with more modern (and visible) technology!
