I cannot speak to the DL 1000 at all! I have never even sat on one! But, I have done quite a bit of work to my DL-650, that may be "transferrable" to the DL-1000. At least, the work may provide you with some inspiration to do further research.

Here is one article that I wrote a few years ago: Steering Stem Bearing Replacement / Upgrade Black Lab Adventures

And, a companion article to go along with it: How I Adjust The Steering Stem Bearings Black Lab Adventures

And, if an upgrade is done to tapered roller bearings, you definitely DON'T want to use the Service Manual for determining the correct tension value! At that point, with the tapered bearings installed, you are dealing with a different "animal".

agree with me that what the manual specs for the proper adjustment, is too loose?

I would you "step out on a limb" and agree with me that what the manual specs for the proper adjustment, is too loose?

This is what I have been trying to get across to folks. BEFORE anyone spends money on a corrective solution, (new tires, steering dampener, or even on the tapered roller bearing upgrade that I encourage riders to make.), I want people to try applying a little more tension to the stem bearings.

PTRider The tightness of the steering stem bearing is tough to quantify. My '04 met the spec when the front end was pulled around with a spring scale and there was no wobble to feel when it was on the stand, but that bike gave a new meaning to "adventure" riding when going fast downhill in a crosswind. I tightened the bearing by feel, and the bike became stable and secure.

ThruST I Have the same issue with the 2005 Wee project bike I just purchased. I think its the steering head being loose just haven't got around to checking it yet. Let us know what you find.

Most often none at all. They are set too loose from the factory. I had a tire wobble on my DL1000 and put the tapered steering head bearings in and set the tension. The wobble was gone and I have not even felt a hint of it. At first the bearings were a little tight so I loosened them just a bit more and they are perfect.

If you have the wobble with any tire tighten your bearings!

Black Lab is right on this.

hwyhound You mention you were camping, is it possible the extra weight of your gear caused this. Did you crank up the rear preload after adding the extra weight? Did the bike continue to do this even after the gear was unloaded?
