This is an old installation but I have the body work off now to clean things up and get the bike back on the road, so I thought I'd share it.

I added an air horn because of too many close calls, and bike horns just don't cut it sometimes. Some might argue it is a silly addition, but I feel better having it.
Compressor mounted to the right down tube...I think that was the original horn location (it's been so long).

Brackets were from snatched from some truck mirror parts. Flat stock was what came in another electric horn. The brackets fit nicely around the frame.

It all fits in there. I will clean up the installation a bit by reversaing the bolts and trimming the relay screw down flush. It must have been cold out when I did this BITD.

are those the ones which play "la Cucharacha" ?
Seems like they`ve replaced the carbs. I guess good car horns would do a good job, too and need a bit less space and no compressor.

But car air horns wouldn't be nearly as cool! I had a set of air horns in my old Fiat Spyder, when I finally came to my senses and replaced the car with a Mazda Miata, I kept the air horns; they're still in the Miata to this day, 16 years later!

A friend of mine who used to help me fix the car (Fix It Again Tony-FIAT, right) used to say that the horns were tuned for maximum attention by women. Well, that's not exactly what he said, but that's the cleaned up version.

Oh, don't forget to oil your horn every 3,000mi, and overhaul every 12,000(just open it and clean it, really)(no I'm not kidding)...
