Hagrid was asking me about my Stebel horn installation.
This week, I saw this in this month's Motorcyclist magazine: A Stebel-like "dual tone" horn, with an air hose separating the air compressor from the horn bell.
Pretty cool, and perfect for a 14R installation:

If this is a "good" quality, then it would make installation much simpler for us.
