As the title says really

I'm needing a couple of pics to see how everyone else has done it.
Also I'm need to know how to wire it in.

Thanks in advance

Split the horn from the compressor makes shoehorning it in much easier. I followed the instructions here

http://www.motorcycleinfo.co.uk/index.cfm?fa=contentGeneric.cwpgfxigzstbrmfs&pageId=2173985

Compressor goes under the seat, and the horn well put it where it fits, but preferably with the trumpet pointing downwards.

My horn part is in the left fairing upper.

Use the wiring from the OEM horn to power the relay.

The compact nautilus horn is half the size of the standard

Excellent Mavi

The ebay listing I won it claimed it was squeezed onto a GSXR750 K8 (and its the compact)
You wouldn't know off hand what the I/D of the curvy fuel lines are

6mm I think.

Is that for connecting to the compressor?

You can use something like windscreen washer tubing.

Yeah as need to replace the lines from the tank and I'll get some more when a order it

Oh, don't use the windscreen washer tubing for the fuel lines, its not petrol proof :p

Fitted with a B&Q bracket (http://www.diy.com/nav/fix/hardware/ironmongery/brackets/Abru-Heavy-Duty-Bracket-L-120mm-x-W-20mm-x-H-120mm-9281734) to the fairing bolt, although I had the lowers to cover it.

Diagram:

I did have some problems to get both horns working ant the same time, but can't remember what it was all about (was a while ago).

I tend to think of it as a pedestrian launcher :)

As in 6 feet straight up when they even look like they are thinking of stepping out from behind that bus while looking the other way :)

Nautilus nesles in around the engine, Magnum is in the belly-pan, stock os where its always been :)

Just looking at the wiring diagrams, can it be directly spurred off the existing loom or is the relay required?
yorkie_chris
08-01-12, 06:46 PM
Use relay, nautilus draws more.

I put horn behind rad, just cable tied through fins as it weighs nowt. Sound goes through the fins without any real losses.

Split it from compressor, mount compressor somewhere else, probably would fit to frame behind upper fairing.


Before this I had it on solid bracket to engine mount spacer pinch bolt, do not do this, the vibrations killed it.

08-01-12, 06:46 PM
I think people have done without any problem, but I did it using a relay.

I'm the world worst at understanding electrics, so if I can do it, then anyone can.

I rerouted the horn connection to under the tank at the front and plugged this spade connectors straight onto the relay terminals. I then ran a feed from the battery to the one on the relay & then one to the compressor.

Then the neutral from the negative battery terminal to the negative on the compressor

Confirmed my suspicions that it was larger current.

Good shout as I was eyeballing one of the motor mounts.

Internal or external?

All I've got is the compressor and horn

The Ebay one (GSXR?) was just the horn and went for about £4 less than a new one including a bolt and external relay. You should use a relay as the Stebel takes 18A vs about 4A standard going from the datasheet.
Just waiting for a Stebel look-a-like (Wolo) to arrive and planning to mount it on left hand Engine mount pinch bolt (Pointy) as I don't want to split it. Looks like some rubber anti-vibration mounts needed from what YC says. I have heard that they don't take well to vibration but will give it a go as nowhere much else to put it as a complete unit.

Don't tell anyone, but spent a few days post GM at Applecross with a former .orger. What with his Nautilus & my backfires could we have caused this > >

The look-a-likes are £30 the genuine ones are £60

08-01-12, 08:13 PM
Yep, be interesting to see how long the look-a-like lasts as the genuine ones don't have a great rep for long life (and I don't even need the relay for my £29, :) ).
Could well be the way it's mounted and vibration etc.

VWP is the devil, spend 30p here and there and the next minute it's £100!!!

The horn should be fine wherever if supported or on some sort of anti vibration mount. Andrew AFAIK any relays are external, the horns simply have a compressor motor with +ve and -ve terminals, mount relay wherever suits.

Just a thought, Chris:
Is there a frame tube that could be pressurised & then use that to blow the horn?
Eliminate electrics altogether.

Interesting idea but you'd still need a switch and solenoid... Unless you want a 1/4 turn ball valve on the handlebar!

Yep!
Got it down £27 in the end as it was the bags of bullet connectors and sheaths that made it jump quite a bit. The cable tools didn't help :rolleyes:
I'm going to have a proper look over the weekend as I did eyeball the front Cylinder mount as a candidate for the mount.

Right here's my set up. Compressor sited under rear seat (little grey thing on left). Zip tied in place with a bit of pipe insulation to help with vibration. Tube goes from compressor to front fairing, wiring as per the diagram posted.

https://lh5.googleusercontent.com/--CfxxrB0Z4w/TwtehUXo1WI/AAAAAAAAAyU/wKyeC8OyLHs/s512/DSCF0865.JPG

Seperated horn lives in left upper fairing, so light just held in place with a light metal strap, using the indicator mount.

I just mounted mine on some bits of strap ally on the rad/fairing mount as per the original pics on here somewhere. Has worked for 3yrs without probs and is full of carp from 36k miles of all weather riding...even the connectors are still functioning and they're rancid.

The relay was temporary attached to the bracket, but now it's moved to where the original horn was.
andrewsmith

Cheers mate

Confirms one of the options of mounting would work.

Anyways, would a miniblade fuse be up to taking the load?
Also would 30A thinwall fit in the bike fuse holder?
musne
22-01-12, 08:07 PM
I'm using 10a blade fuse for the power socket (cigarette lighter socket) and a 5a blade fuse for the horn.

Not sure about the rest, but all I know is the fuse Amps must be the lowest on the circuit.
