After 14 years, my Stebel Nautilus air horn died. So I simply replaced it. Thought I'd snap some shots of my installation in case anyone was looking for ideas.

Simple angle iron (1X1X1/8), 2 1/2 in long. Three holes, one for the engine mount bolt, one for the horn itself and a small through bolt to mount the relay and ground the horn itself.

Here's the (old) assembly, on the bench.

A fused line (horn pulls 18A) back to the battery. I lengthened the factory horn wires, using spade connectors to connect to the (supplied) relay.
Final installation.

I removed the nut on the upper right hand engine mount bolt, put the horn assembly in place and re-torque.

I did add a hose for the air intake that runs up and behind the frame cross tube to help keep trash out of the horn.

Horn cost me $50. It is worth every penny! It sounds like a semi and will definitely get people's attention.

(Yea... I know.. bike needs a good cleaning!)

Nice and tidy install.
It begs for a write-up and posting to the Dropbox.
Anything else you think you'd like to add in?

Nice job - I've been using a pair of Stebel Magnums because I didn't think any of the other types would fit. Good work!
