Lessons learned from installing a Stebel Nautilus on a 2008 DL1000

This was the first time I actually worked on my new bike, so the job took incredibly longer than I would have suspected. Here are my observations.

1. Go with the Pat Walsh mounting bracket. Even though I had to 'custom bend it' to make the Stebel fit in the left side of the fairing, the bracket helped. Make sure you test for a proper fit with the fairing on - turn the handle bars full left and full right and make sure you have clearance. If you are able to do an install without bending the mount you are a better man - or woman - than I. Note: the smooth finish of the bracket against the smooth finish of the 'rod' I mounted it to makes for an acceptable but not great snug fit. If I did this over again, I might try mounting a thin strip of rubber or wind some electrical tape around the tube to give the two surfaces some additional bite.

2. While the Eastern Beaver wiring kit was recommended to me, I went with the Stebel one which is cheaper. In my opinion, the Stebel kit is a waste of good cash. The hardware size doesn't match up with the gauge of the wire. You do get a nice inline fuse holder, but the kit was not worth the cash. I ended up having to buy additional connectors any way. Either buy the connectors and wire on your own or part with the cash and go with the Eastern Beaver. I am sure the Beaver will cut your install time by a great deal.

3. GROUND TO THE BATTERY. I finished the install on my bike and the horn didn't work. Why? I had grounded to a screw. Do yourself a favor and go directly to the battery.

4. There are plastic 'buttons' that snap on and off to hold the front of the fairing in place. The same engineer who decided to place the spark plug and the factory horn behind the radiator must have been the same guy who selected these fasteners. There is a little pin that sits in the middle of these fasteners and the damn things kept falling out of the button every time I lined them up to re-install the fairing. Be prepared and watch for this possibility.

5. Oh, and did I mention I could not find the horn???
Yes, I tried to pinpoint it by honking the horn. I THOUGHT it might be behind the radiator, but wasn't sure. And I was hoping it wasn't behind the radiator! Turns out that if you back out three bolts you swing the radiator out of the way enough so you can get to the horn wiring. Unfortunately, that same engineer who placed the factory horn in the land of the damned did not color code the wires that attach to the horn - they are the same black with a silver dash mark. They need to fire that guy (gal)! Be prepared to test for which wire is pos/neg. I am guessing the Beaver plugs right into the attached receptacle lining up the pos/neg quick and proper like making this a no brainer.

I won't tell you how long this install took as I have read some say it took them two hours and I don't want to completely embarrass myself. If I would have known what I now know, I could probably do the job in 90-120 minutes. However, as this was my first adventure in disassembling and investigating how and where stuff is attached to my beloved V, the install was a lengthy and painful one. By the way, the night before I began working on my V, a cat decided to deposit a pile of crap inches from my front wheel... an omen perhaps? Regardless, it didn't help my installation woes having those aromatic fumes swirling about me while I was lying on my back on the concrete...

Any way, the job is complete, it works, it is as loud as everyone claims, and I have lived to tell the tail. Thanks to all for your suggestions, patience, and guidance. I hope my lessons will be of assistance to others who chose to embark upon this air-horn journey.

It doesn't matter which wires from the OEM horn go to the 85 and 86 relay terminals. They just energize the coil and polarity does not matter. The same is true for the 87 and 30 terminals to feed the Stebel. Polarity doesn't matter. http://www.vstrom.info/Smf/index.php/topic,1418.0.html has info on the plastic rivets. Once you get used to them, they are easy to use. A grounding clamp from Home Depot and a piece of 1/8" aluminum bar work well for mount too. I actually used a 1-1/2" angle that was 1/8" thick and cut most of one side off. It's a little stiffer than a simple bar. I have a grounding block on the left side so put the horn on the right.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

Good idea - I remember reading somewhere that the aluminum frame of the V doesn't do a good job of providing a solid ground. Found it - http://www.calsci.com/motorcycleinfo...m3.html#Lights

2nd Wolo

I added my second Wolo(Stebel) today. Just a bit underwhelmed.
It's way louder than my truck or car but I didn't get the same satisfaction as with just one. I Used a Bosch Dual 87 relay to uncomplicate the install.
I ran it fused to my battery instead of the BLUE Sea Fuse box. I thought they used more amps(less than 20 for both).
My goal was to cause the idiot talking on the cell to lose it out the open window when they pull in my lane.
I paid less than $45.00 for both Wolo's, HF on sale with a coupon.
Eastern Beaver is top notch. I just chose to make my own wiring harness.

Relay follow up

About four weeks after my horn install, it quit working. A quick look at all the obvious potential culprits and I noticed discoloration at the relay terminals. Yup, water seeped into the relay and fried that sucker. I made a quick trip to NAPA for a replacement relay and while there purchased a tube of silicone. I silicone-sealed around every relay box joint and slits where the terminals extended from inside the relay box, let the silicone dry, performed the new relay install, and voila - six months (so far) of trouble-free performance.

I would be interested to hear how others have resolved or prevented such relay/foul-weather mishaps.
