You are at about the right mileage for the filter to clog, so that's what I would suspect. The other issue every DL1000 owner will see is the Throttle Position Sensor.

Do the fuel flow test and see what you get:
Quick fuel pump flow test.


The usual symptom of a dying TPS is that the bike dies at the first stop light after several miles on the highway, and it is hard to start and runs badly. After working the throttle back and forth several times with the bike off, the contacts get cleaned off enough for the bike to then start and run fairly normally for a while.



Either of these problems are fairly easy to fix on your own. A dealer may be reluctant to install the external fuel filter unless they are somehow very familiar with the DL1000. The problem is that a new fuel filter is nearly $300. The actual filter element is only about the size of a pack of gum, and it will clog again rather quickly. The parts for the bypass are less than $20, and you can use a much larger and better filter. It's a very well-proven fix that's in use on hundreds, if not thousands of Vees.

A dealer should be able to diagnose and replace a TPS, but again, unless they're familiar with the DL1000, they may not know this is such a common issue and could waste a lot of time chasing other things.

 

Interesting. I was riding out west about a year ago and after about 200 highways miles riding between 75-80mph, I came in to a town for gas and had to go through a couple of stop lights. Sure enough, when I stopped at the first light, the bike sputtered and shut off. Took about 30 seconds but she came back on and I gassed up and left. Since then, I had a dealer take a good look at it as I suspected the TPS or a TBS issue. The dealer did fix the dying out issue as it has not happened again, but now, after riding for some time and coming to a stop, the bike idles pretty high around 2k rpm. I've found out that if I pop the clutch, the idle goes back to normal levels. Any ideas on this symptom?

I'm installing new aux lights and a horn this weekend so I'll take the time to do a fuel pump test. I must say that I am fairly good with a wrench, but no expert. After reading the procedure for the external filter, I'm not sure I myself could pull it off.

engine stays in higer revs at stops - clutch issue?

 

If the problem only exists on a cold start, it's most likely not the TPS or filter. As Greywolf pointed to, a simple idle adjustment or a more complex fast idle adjustment is necessary. In the meantime, open the throttle during problematic starts and idles

Excellent points. And it certainly couldn't hurt anything to do a throttle body sync and check the fast/hot idle.


One other thing I'll point out is that you have to adjust the idle speed a twidge (at least on the early Vees; not sure about later models) when temperatures change. That's what the philips head adjuster on the left is for. I generally need to adjust mine three or four times a year. As average temps approach freezing and/or when it gets hot out, the idle speed changes so you have to compensate manually.
