Full Version: Matching Horn for Poor Boy Conversion

For those of you who have converted to an automotive alternator, you probably now have only one horn. Possibly, if you are like me, the anemic beep of one Honda horn (really more of a buzzer) is not capable of getting anybody’s attention much less potentially saving your life. I have improved it with an automotive (a real horn) replacement, but in order to do that I had to make a few changes.

I made a new longer mounting bracket to accommodate its larger size (principally the bell opening). The horn was mounted on the rear side of the bracket rather than the front to clear the lower fairing that surrounds it. The new horn’s diameter and width are slightly larger than OEM (see pictures). I used .125” aluminum stock about the same width as original, because it doesn’t rust with or without painting and will flex as required to clear surrounding engine, fairing, and frame parts.

BTW I have another horn like the one I used for sale since they were sold as a dual tone pair. PM me with your offer and we can get it to you for your conversion. With it, you too can have a real horn without going the air horn route without the need for a relay, compressor or extra wiring.

I like your modification and thanks for sharing it with us.

One can never have too much horn on a motorcycle, although I did see one guy with a GL1100 and he had a full train horn setup from a diesel locomotive on the dash of his bike. A little bit of overkill, but, he sure got everyone's attention when he hit the horn button.
Part 2
As more of the astute readers might have noticed, the project needs more work to be complete. You’ll need to trim the lower plastic filler panel. It needs to be notched to clear the horn bell in the shape of a big U and the front face trimmed to clear the horn body just behind the mounting stud. I used a Black & Decker spiral saw and took my time taking a little off at a time and following my chalk marks to indicate interference points.

Using a cut and try procedure, it came out good, but not perfect since the lower fairing attaching point did not line up with the filler panel. So for now, until I have to remove the pieces to service the spark plugs, when I can trim a bit more, I secured them with a zip tie.

Now, as Mr. Paul Harvey (RIP) used to say on his radio show, “That’s the rest of the story”.
I've had Fiamm Freeway Blasters on our 'Wing for a few years now and they definitely make a difference. Bought them at Princess Auto for $16 each if I remember correctly. Simple installation, too.
