Not same gen as your bike, but I had similar problem last week on 2005 K12GT.... horn worked the previous time I used it, but not when I really needed it! :boom:
Checked fuses, pulled panels and checked all the wiring... then I noticed the horn switch wasn't quite sitting right... the end you press had jumped slightly out of its position, enough so a normal press couldn't activate the horn.
Pressed hard on the end of the switch and popped it back into place.... horn fixed... phew. :wtf:
I ran the Stebel Nautilus on my GT for many miles. It's a tight fit (I put mine under the right side fairing, as I had HID ballasts under the left side), but it worked well.
The upside is that it's loud. Dämn loud. No, even louder than that.
The downsides are that it's big, so fitting it up under the fairing panels is tight. It takes a lot of power, and requires a 30 amp dedicated circuit and relay. And there is a slight delay as the air pump spools up. But then, look out!
Some riders have instead gone with one (or even two) "conventional" style horns, just using a much better quality, and much louder, model. These fit in much easier, and can usually be run off the stock wiring without any mods.
The Hella Supertone and the Fiamm Freeway Blaster are popular choices, although there are many others.
Here is a review of aftermarket horns by WebBikeWorld. Ignore their bitching about the Stebel failures. I've never and any issues with the Nautilus, and neither have the vast majority of riders. The rest of the article has pretty good info.
I bought one many years ago, after blasting my horn in a friend's condo neighborhood at 5:00 AM while making a U-turn in his driveway. It does its job perfectly. It is simple. It does not interfere with using the horn.
The drawbacks are:
* It uses the left handlebar's accessory mirror mount hole. I had a Techmount GPS mount there, so I moved it to the right handlebar mirror mount hole.
* K1300GTs and above do not come with the necessary mirror mount hole. Do not bother ordering one, it won't work.
I had also read someone's post about a slight delay with the Stebel Nautilus....... I put one on the K12GT (2005) anyway, and kept the OEM horn attached as well so I get triple-tone... I don't notice ANY delay whatsoever between the horns.. except when the damn switch popped out of place and I had nothing! :wtf:
I have my OEM horn and the Stebel all go on at the same time. I do not see a delay , and I checked it out this AM. Scared the beejesus out of a little old lady trying to cut in my lane of the local freeway.
I have a 2009 K1300GT that starts and runs normally when the outside air temp is below 90 degrees. When the temp gets above that value (cold engine), It will fire and run briefly and quit. It won't fire off again unless I shut the key of and start again. Even then, same result. If I reset a...
So for 15 years I've been riding BMW's and singing their praises. NO MORE!
Hiking in Death Valley today I come back to the trail head, get on the bike hit the ignition and it starts up making the noise like it used to before I had the cam reservoir changed. (It hasn't made that noise in the 2...
My final drive crown bearing gave up 2 weeks ago at 28k miles. I've gotten it apart and was shocked to see that this is (was :-/ ) a totally sealed bearing! After reading about the 12k oil change interval & doing it, and even people changing final drive oil at every engine oil change, I had...
My first bike when I was 15yo was a '76 Suzuki GT250 Ram Air . . I was sooo cool! Later a '81 RM125 that I raced once and missed the start of my 2nd heat cuz I was peein' :wtf: It was a sloppy, muddy track so no real big deal but I did join the race in progress just for the experience. The 1st...
