I had dropped my 2005 FJR-A about a month ago. It's totaled out by the insurance company and I have a bid in on a FJR-AE that I hope to have sometime in May. All the goodies I had installed on my '05 I'm going to put on my '06. I had a J&M 40 channel CB/intercom, Garmin 2610 navigation, Escort 8500/X50, XM radio, Blinder radar laser jammer, heated grips, Corbin heated Dual Canyon saddle, 12volt accessory outlet, cigarette lighter, Scorpio alarm and Datel volt meter. I think the FJR-AE will come with heated grips and I know the Corbin saddle will no longer work with the 2006 models. I kinda like the Corbin smuggler setup since it can be removed and setup for duo ridding also.

I'm looking for the Baddest and loudest horns available that will fit under the FJR's fairing. What are some of the best horn mods out there?

Sorry I didn't mean to duplicate post. I see Walrus is working on a set of magnum blasters and there are older post also. I wonder if FJRRandy's were really flukes or would it be better to order the Nautilus horns instead? I want the loudest possible horns that will fit.

I don't know about fitment on your '06 as I have moved on to a V-Strom, but my Stebel Nautilus horns are WAY louder than the Magnum Blasters I had on my FJR. They are actually air horns but have a very compact compressor all built in one package. And there is no delay waiting for the horns to pressurize either. Google Stebel and their website has audio samples I think. Twisted Throttle has several pics of a mounting on a V-Strom that may be helpful.

I actually ordered 2- Magnum blasters and a compact Nautilus. Maybe I should just change it to 2 compact Nautilus and call it a day.

Nautilus

qmotion,
I have the Magnum Blasters where the OEM horns were. The Nautilus won't fit anywhere on my ABS FJR, so I hung it below the right auxilary light bracket....not a pretty sight! If you don't have ABS, you should be able to mount it where the ABS modulator would reside.
The point is, I don't see any way to mount two of the compact Nautilus horns & have a decent looking installation.
As for separating the air horn from the compressor; that would cause a delay in the horn's operation. :(

No delay when you run a 20" air line between the two. Already finished that part and tested it. Any longer line and I'd have to agree. I'll be starting the custom mount soon and will have pics to show how it was done.
As far as pre-'06 models with ABS.....this install should still have enough clearance if it goes the way I hope it will.

I fitted the Nautilus to my 05 ABS. I would post photos but can't figure out how to do it.

I found a stainless steel spatula (use it to lift eggs out a frying pan) and cut about 2" (50mm) off the handle to use as the mounting bracket.

Secured it using the right hand bolt that holds the steering stop on. Just fits in there. High enough up to avoid hitting the mudguard and clears the radiator. Close to the brake pipe so had to be careful to avoid rubbing.

Just wondering if it will stop airflow through the radiator in warmer weather.

Kept the original horns wired and simply connected onto one of the horns without using the relay. I assume it would blow the fuse if there was overload.

Very noisy :twisted: .

If anyone wants to see it mounted I can email photos.

Will be away for the next week though.

Oh, there WILL be an overload with the stock wiring. You can bet the farm on that one.
You're running approx 3-5 amps on the factory horns, and about 18 or so with the Nautilus. The horn circuit is fused at what, 7.5 amps? Not to mention the 20 ga factory wiring.

Good luck! :roll:

If the fuse doesn't blow then you could end up welding the handlebar switch contacts together when you go to use the horn.

Could cause a bit of embarrassment, just imagine if it happened when driving past the local hospital one Sunday morning in your first car to which you have added a nice powerful set of airhorns without a relay :shock: :oops:

Looking forward to the setup, FJRandy....planning on doing the relay for it? or is it the same as needed for the Magblasters?

Totally different setup, doc.

I'll use the same Bosch relay, but 10 ga wire instead of 14 ga, and a much shorter run considering I'm mounting the compressor on the right (batt) side. It's MUCH more critical to get the most current to that compressor so it hits fast. I've been so damn busy, I haven't had a chance to go near that project yet!
I found the proper size tube needed to go into the horn side once the compressor is separated. 5/16 o.d. X 1" bronze tube. Fits right in the hole, and 5/16 fuel line fits both ends perfect! I found it at a place called Tractor Supply, but I'm sure it's available in more places.

Don't worry, as soon as I get rolling on it I'll take some pics.

Images of the horn mounted with the original horns in place and working.

Was worried about the airflow being restricted to the radiator, but appears to be OK after 2000 miles in really hot summer weather.

Is the Nautilus substantially loader or about the same with maybe a different tone? I bought one but installed the dual Magnums and they work fine.

Randy, I too would be interested in a good solution to mounting the Stebel Nautilus Compact horns, so please let us know on what you come up with - thx

Loudness

qmotion,

I have both sets, and, yes, there is very little if any difference between them except the pitch on the air horns is higher & maybe more piercing.
The combination sounds like Amtrak.
If you happen to have an '03 you can bury the Nautilus in either side of the fairing lowers right behind the external turn signals. Forget it on the later models (don't ask).
I have my Nautilus hung off the bottom of the RH auxilary light bracket.

Is it correct to assume than that the choices are either a single Nautilus or dual Magnum Blaster horns?
The other question is why must the horns be mounted on the front of the bike, I would have thought that there would likely be more space under the back wheel. Obviously there will be some impact in sound due to the Doppler effect but I would have thought that given how loud these horns are it would not be a big issue?

JamesK,
There isn't much of a choice around the luggage rack, but I've looked at the possibility of mounting the Nautilus in front of the mud flap at the front of the rear swing arm. The only set back would be that the rear wheel must be removed first. There isn't enough clearance without that.
It could be supported on top of the swing arm by drilling attachment holes.
there isn't enough distance from front to back to be read as a doppler effect.
Good luck.
