How to split and fit a Stebel Nautilus

(RIP) Shenzi · Oct 9, 2008

First of all thanks to Thorium, his post on Advrider led to my actually fitting the Nautilus on my bike after several months of trying. He fit his compressor into the space provided for the carbon filter, check out his post on Advrider.

In the photo below you can see the plastic intake that fits into the compressor body, this is the only thing that stops the compressor sliding out. Ease it off the compressor with a fine screwdriver then slide the compressor out.

I used a tube from an Ultraseal bottle, stuck the thing in as far as it would go then wound some self healing tape around it. Hasn’t moved in 2000 miles so I think it is OK.

I painted the compressor black and cut some closed cell foam to the size of the compressor on one side and the fork on the other. I then glued some flat plastic on each side of the foam. This was to centre the compressor and allow the cable ties to hold it in position.

My chosen place for the relay is on top of the compressor. The relay is connected to the Magnum horn which I fitted in place of the original.

As can be seen in this photo, the horn clamps onto the fork perfectly. For the compressor I put a stainless jubilee clip on the fork in such a way as to support the unit. Taking this photo this evening I noticed that the top cable tie has gone so I may put a jubilee clip in its place.

All the usual disclaimers, this is what I did on my bike,I don't suggest you do it on yours, your choice!

Nice one Shenzi. :thumb2

Sorry guys, forgot to post this photo which shows the compressor halfway out of the plastic horn body.

Which bike have you done this on ? I have fitted a couple of nautilus horns on 1150GS and 1100GS's and they fit in nicely under the headstock without any modifications :nenau

seems a lot of work when all you have to do is bolt them on.

12GSA, absolutely nowhere to just bolt it on!

Nautilus

It's ok bolting them on with thay crap fixing system (for cars?) but yoiu go off
road over rough terain and they come off! don't ask how I know, this idea looks good but for off road going the forks might hit something on full compression.

When I go offroad I use an offroad bike

Definitely agree with you, it wouldn't last two minutes. The Thorium option would be OK though.

Mines been fine :nenau

maybe I should go further off road

Gecko, that doesn't look like a 12GSA to me and that is the bike we are talking about

We know there is no problem fitting the Nautilus to 1150s.

First, thanks to Shenzi for a good write-up on splitting the compressor.

Just want to point out that the trumpet part is very light, and is not likely to come off until kingdom come. The compressor needs to be firmly mounted. The original bolt mount is strong, but needs to be firmly mounted if used. (Hose clamps or heavy duty cable ties is probably sufficient) The original horn mounting points will not provide adequate support.

When mounting anything in this area one needs to take into account maximum spring compression. I did this unscientifically, by measuring the dust marks on the sliders left by precious off-roading (I have been pretty close to bottoming out a couple of times) and added a bit of extra safety margin.

I thought our man above was talking generally about the strength of the fitting brackets :augie

but you get top prize for spotting the odd one out

it's an 1100 though.... not an 1150

In case someone missed my earlier post: I had no problem fitting a Nautilus to an 08 12GS:

Err, maybe I did notice it was an 1100 and decided to test others
