Hux has got the Horn

I've noticed that the horn on my FZ6 is, how shall we put this diplomatically..... shite. This came to the fore when riding along a dual carriageway when a car joined from the slip road on my left so I moved over into the fast lane as it looked like he was coming straight out in to me. He did that, but also swung straight from the slip road straight into the fast lane in front of me as he wanted to overtake a car somewhere in the distance I guess. I hit the brakes and laid on the horn and a sound a bit like a gnat farting came out which he completly ignored :(

To remedy this I invested in a Stebel Nautilus Compact air horn which raises the sound level of the horn from the original aforesaid gnat fart to 139 dB. Ouch!

Those friendly chaps at eBay provided one of these for £20 and another tenner got me all the wiring kit (well I could have bought a bag of 100 spade connectors, but I only needed 6).

This morning saw the installation of this little puppy, after some dedicated reading on the FZ6 forum to see how they did it. The inside left fairing appeared to be the favourite option, so I set to work on that. The immediate issue is that there are no mounting screws in a sensible place that allow the horn to be secured. However, have cordeless drill, will travel, resulted in the below.



You can see where i drilled a small hole in the fairing, the ouside of which is covered by anothe bit of fairing, and the inside of which is hidden by the inner fairing. Move along now, nothing to see here :)

The horn itself then nestles in the side there, and a cable tie is there for emergencies while I run it in in case it works loose.


With the fairing back in place you can only just make out the logo sticking out the bottom.





And looking up from the front wheel you can see the pisspoor original (now disconnected) and the new HORN.





Disconnecting the original horn leaves two wires with spade connectors on the ends, one being ground, and one being the horn control signal. Luckily the relay that powers the new horn needs two signal, one being ground and the other being the horn control. And by feeding the wires back into the frame on the left hand side they just reach the relay which nestles in front of the battery. So that's one easy bit of the wiring done. The more complex part is getting a 12V from the battery, via a fuse, to the input of the relay, and from the output of there to the horn. While I was routing that I decided to route the horn ground back the same way to the battery ground rather than the frame. The wires all get sheathed in nylon ... errr.. sheathing (you can see it coming through the plastic clip behind the horn in the first picture on here so it almost looks professional).

When I work out how to get video on here I'll take a clip of it. But it's loud... damn loud!!!!!!!

Lets see the motorists ignore the horn now :)

Edit:-
Thinking about how the horn was perched on a screw through the plastic I decided to make something a bit more robust. When I say "make" I of course mean standing in the bracket aisle of B&Q trying to work out what I could cannabalise to do the job. It turned out that two right angle brackets coming to a wallet friendly total of £1.90 were just the job. One goes on the inside of the frame to go vertically up and then over the top of the horn. The horn then securily bolts onto to like this.



To provide support for this, I hacksawed the other bracket to produce a flat plate to go on the outside of the fairing. This is small enough to be covered by the outer-outer fairing, but large enough to spread the load across an area of the plastic instead of a small point where the bolt goes through. Like this.


Everything fitted back together with a bit of fairing jiggling so I'll see how it is on my road test tomorrow in to work.
