Beer30's Stebel Horn Relocation

[BEER30]

I got myself a Stebel Air Horn but did not wish to place it where the factory horn was located , nor inside the front fairing like most others . The fact that inside the front fairing muffled the optimal decibels that the Stebel air horn provided . Relocating it in place of the factory horn allowed optimal decibel sound on the right side of the RSV, but not on the left side . I wanted equal amount of sound on both sides of the RSV, so I searched numerous possible location as to where to mount the Stebel air horn . I looked towards mounting up in front under the triple tree on the front forks , but not enough clearance and bad idea if the front forks were fully compressed . I looked towards mounting under trunk , but did not want the navigator to jump up and disrupt my driving if I were to suddenly blast away , if you know what I mean .

So, I looked towards the underside of the RSV. And to my observation , there was enough room behind the lowers and along side of the oil filter to where a large enough cavity was located to mount the Stebel air horn . I made a mount simply out of 1/8” x 3/4 “ x 2 ½” metal strapping . Using the exiting mounting bolt on the Stebel at which I believe was a 1/4” diameter by 1”, I drill a 1/4" hole on one end to secure to the Stebel horn . I drilled a second hole 3/8” measuring from center of the 1/4 “, 1 3/8” to center . Pictures 1 and 2 show how I made the bracket.

 

Note:You may want to pre-wire the horn mounting as I did by making pig-tails with plug-in terminals as you will have to remove the horn during oil changes.

 

As you see in picture 3, a 14mm acorn nut that is connected to a bolt which passes through the frame . I removed the acorn nut and removed the bolt. Taking that bolt and passing back through the 3/8" hole on the new mounting bracket on the Stebel horn and placed it back into original hole and re-tightened the bolt with the orriginal acorn nut . You will want to maneuver the horn to where it does not make contact to any other part of the RSV, especially the oil filter, then tighten down the bracket .

In pictures 4, 5 and 6, you can see that the Stebel horn does hang down lower that the driver’s floorboard brackets , but not as nearly as much that the motor’s oil pan . I have not had any issues as of yet going over obstacles such as trailer loading or curbs, but do take precautions at the least . I also used the air tube inlet that was provided with the Stebel air horn and routed the opposite end up and behind the lowers to not take in water during rain or road wash.

 

Wiring the Stebel, I used the relay provided when I purchased the horn. I mounted the relay under the right side battery cover. There are numerous threads on how to wire up the relay. I chose to go connect the main power to the relay straight to the battery and ground it to the frame. To activate the air horn, I connected the factory horn terminals themselves. Therefore I did not have to monkey around running longer wires, nor adding more drain on the RSV’s wiring. Muffinman was gracious enough to supply the terminals tome and I cannot remember the correct name of these. I have seen at the auto parts store. These terminals have 1 female with 2 male blades on them, which allowed me to both connect the factory horn wiring and the wiring back to the Stebel horn relay .

I have been running my Stebel air horn in this location for almost 6+ months now. Placed over 3K miles on the scoot even through major rainstorms. By mounting the Stebel under the scoot, the horn itself is projecting it’s blast towards the ground, echoing the 138 decibels equally on both right and left sides of the RSV. The Stebel horn has not taken in any water to cause malfunction as of yet and with the horn itself is pointed to the rear, it does not scoop up any rain or dirt. Plus I still have the factory horns as well!

Looks good!! I didn't wont mine on my RSTD to be visible. I used a similar method. I seperated the horn from the compresser. Mounted the horn under the bike. Ran a hose around to the right side cover under the seat. Mounted the compresser in between the frame and battery box and the relay behind the side cover. Had it on the bike for over a year now, works pretty well.

Nice idea, Beer30 but around here that horn would have been toasted so many times over.. I've crushed so many troll bells under the bike because of the lumps and humps in most parking lots and side streets around (to slow stoopid people down).. However, it does make it a lot handier to reach.. Mine is under the front fairing, loud enough, protected from rain and the road.. but a pain to reach if you needed to..

 

I may look at this again come winter project time

Salty .....Of all people , I should not have to tell you on how busy we have been to do anything outside the civilian life !

 

 

 

 

Oh by the way , next office meeting is at the local strip club tomorrow night , are you still planning to attend ? I need a Head count to see how many brass poles will be needed . You know how these union workers are !

U so FUNNY!!! Me Love you Big Time GI!!

Does it make your bike jump :scared:when you blow the horn?

I looked at that location (underneath around the oil filter) cause the thing did not look right to me...replacing the stock horn on the right side. But there was one thing that kinda caught my eye...

The instructions had this Bold writing on it...

IMPORTANT!

Stebel Nautilus Compact Air Horn MUST be installed with the cylinder vertical within 15 degrees as shown here..

It showed the electrical connections pointing down. I'm not sure why they inclued this in the instructions...

Let us know how it holds up laying flat.

Come on now , Do you believe everything you read ? I assume that is so the unit can drain any moisture out of the system . So as I precaution , I toot my horn occasionally when in an area where it not distracting ( out in the middle of no where) to clear the unit of any moisture that might have accumulated . plus it keeps the armature and brushes nice and shiny within the pump motor !

On that note ; prior too the Stebel , I had the Harbor Freight air horns . That compressor was mounted horizontal also and underneath the scoot . I had it on the scoot for over a year and a half without any problems . Had the trumpets mounted under the floorboards . Had not had one issue until I cracked one of the trumpets . That was the only reason I replaced it with a Stebel .
