As much as I love stock configurations, I just had to get a better horn. The factory horn belongs on a moped, not a motorcycle.
So...
I got this
The Stebel Compact Nautilus (Waterproof version)
I purchased it from here:
http://store.onlineautoparts.com.au... Air Horn Black 139dB Plug'n'Play Wiring Loom
This is the WATERPROOF version of this horn which I could not find anywhere here in the USA. I had to get it from Australia where the weather is more, um, severe.
It came with the most sanitary installation wiring loom I have ever seen, and the installation was CLEAN, with ABSOLUTELY NO MODIFICATION to the original Moto Guzzi OEM wiring loom. Only 2 simple blade connections and two battery connections.
All you have to do is remove the left side cover, fish the loom up the frame and along the lower side of the tank behind the main frame rail, unbolt 2 tank retaining bolts to lift the loom under the tank mounting tab, and connect it to the battery. It has a relay which is provided and connects the power feed directly to the battery. It even has its own waterproof contained fuse block!
Back down by my mounting point, you connect the stock horn wires to the newly installed wiring loom, and they control the activation of the relay, hence, the electric feed is completely isolated from the stock wiring loom. No possible damage to the wiring of your Stelvio and no chance of a blown factory fuse!
I selected a mounting point on the aluminum engine bash plate. Drilled 1 single hole and mounted the horn retaining bolt to the plate. The horn itself has another mounting clamp built into it, and a retaining screw attaches the horn assembly to the retaining bolt. Easy as pie and SOLID as a rock. The bottom of the horn is level with the bottom of my bash plate, and I checked out the lean clearance, and there is PLENTY, but for a track day where I might have *EXTREME* lean angles, I can quickly detach the horn, or if I move back to someplace with serious mountain roads, I will just use the original bracket to locate the horn 1.5" higher up by bolting the original bracket in a vertical position to my newly drilled hole, and attaching the horn retaining bolt to the stock bracket hole and then the horn to the retaining bolt! Could not be any easier.
The only reason I didn't use the bracket to begin with is that I like the SOLID mounting directly to the bash plate and the horn is perfectly vertical which Stebel says that it needs to be for proper operation and longevity. If it was on the original bracket, even though it is short, it would vibrate some and I didn't want that.
Also, this kit came with a specialized dust filter which you mount over the air intake tube, and will prevent any particulate from entering the wind turbine. The most fantastic thing about this whole setup though, is that in addition to being waterproof, the air intake is pointed towards the rear of the bike! You can see the little stem at the bottom right of the horn in the picture.
Now, the meat of the matter. THIS HORN IS DEAFENING! 139 decibels and they aren't kidding! It will wake the dead! Don't blast it in your garage or your ears will be ringing for some time.
If you want to know what it sounds like, there is a file on the selling site. It's down in the description. Click "Be heard - Be noticed - Listen here" and you will hear the horn. Make sure your speakers aren't on max volume!
I had to use the horn this morning when a careless driver started to come over on me. He swerved away from me like he had just heard a freight train coming at him. You should have seen the look on his face when he saw that it was just a motorcycle. I loved it!
I used some additional split hard plastic wiring insulator/protector tubing which I bought at the auto parts store, to put around the wires from the original horn wires to the relay connections as they are not protected by the plastic shrink wrap of the loom itself and sealed it nicely with some electrical tape. It looks like a factory install job. I then zip tied the wiring to the point where the engine protection bars bolt the the engine block and there is enough slack to change out to the factory bracket extension should I wish to.
The entire photo album is here:

I hope you like what you see. Even though I am a "stock" kind of guy, I HIGHLY recommend this setup. You will be heard! No doubt about it. :ugeek:
***UPDATE - I was looking at the picture of the wiring loom on the retailer's site, and I noticed that the fuse holder in the photo is NOT what is on my loom but otherwise the loom is the same. My loom has a MUCH BETTER waterproof version which you can see in my photos. You can also see that the relay control wires are not protected by the shrink wrapping, and that is why I used the protective sleeve I mentioned. Enjoy!
