I purchased a 2005 DL1000 this summer in Oklahoma and rode it to San Antonio, TX. I live in Washington state and keep it at my daughter's home for winter riding. It had about 7800 miles on it when I bought it and ran very nicely. At about 9300 miles it started to loose power at 9300 to about 4100 RPMs. Following an east Texas ride yesterday I took it to the dealership that I had do the 7500 mile (obiously late) service. The service manager asked if they could take a quick look to see if any hose clamps were loose etc. 90 minutes later I looked in and the bike was apart with three techs going over it. They had the ECU on the work bench, testing it. In spite of their best efforts they couldn't find anything. The tech noted that the TPS voltage was off a bit and corrected that. They put it back together, took it for a test ride and it is still doing it.

They didn't charge me anything but asked if I could bring it back when I return to Texas in January. They are stumped at this point. The service manager reviewed all of the service bullitens but found nothing. He is going to contact Suzuki next week.

Has anyone ever experienced anything like this?

This seems to be a typo. If you mean you are losing power at higher rpms, do a fuel pump test. See the sticky posts at http://www.vstrom.info/Smf/index.php/board,15.0.html for handling fuel pump issues.

That wasn't just a typo but rather a complete brain failure.

The engine misses and falters between about 3500-4000 RPMs and then smoothes out with good power. If I am in sixth gear and let it drop below 4000RPMs (about 70mph), it starts to shudder as if it is fuel starved. I would think that a fuel pump problem would be indicated at all RPMs but it is something worth checking out. If/when they resolve the problem, I'll post the results.

I just finished reviewing a few threads at that link and a guest posted a thread on exactly the same problem. A member referred him to Service Bulliten 35 which calls for a new ECM to resolve this problem. Whoops. It looks like I'll be forking out some cash. It is interesting because the service manager and I were looking over that bulliten.

A problem range like that is not a fuel pump issue. It's most likely a lean spot in the fuel mapping that may involved throttle body synch issues or involve other sensors too.

That model year suffered from a severe shortage of fuel in the stock map. There is also a recall on that model's ECU. Check to see if your dealer has the service bulletin on the problem. You can add a PCIII and fatten up the mixture to your liking and that will eliminate your issue as well.

I also had a 2005. First, it'll probably never really be very happy in sixth gear under 70 mph. I could cruise along a flat road OK at 65 in sixth gear, but accelerating wasn't smooth at all.

Mine had quite a stumble between 3500 and 4000. After working with my dealer, I was able to get the replacement ECM under the technical bulletin at no charge to me. The Suzuki rep said the bike was "never intended to run in that RPM range anyway, and the internet people exaggerate any problem the bike might have". I had to roll my pant legs up.

The new ECM improved, but did not solve the issue. I eventually put a PCIII on it, which helped a lot (also added aftermarket pipes). The 2005 bikes have a reputation for the worst fuel mapping.

If you feel up to it, sync your secondaries and balance the throttle bodies yourself. It's not really very difficult. Chances are you'll have the patience to get both set closer than the dealer would. This will help smooth out the bike a lot.

Shep, Larry, this is most unsettling. I've had a lot of bikes over the last 45 years, presently owning four, and obviously didn't do my homework on the VStrom. I'd read a number of road tests on the DL1000, thought it was one of those "bulletproof" bikes and when I bought it had no idea that any model year was considered to be defective. It was my intention to keep it stock and just ride the hell out if it. Little did I know that it would require significant, and expensive mods, just to make it run right.

Thanks much for your insights though. Service Bulletin 35 addresses the issue and perhaps Suzuki will step up to the plate on the ECM replacement, even though it might not totally resolve the problem. Since I am not the original owner I won't hold my breath though.

These are bulletproof bikes and none of them are defective, and why do you think you are going to spend a fortune to make it run great? Have most of your previous bikes had carbs/carb systems, all bikes have there quirks....have you been free from any on your past bikes? There is nothing signifigant "if anything" that needs to be done to 90% of these bikes. I'm confident you'll get this issue sorted out, and you'll forget all about it. Won't matter that your not the original owner, a tech bulletin will cover whomever owns it. Hopefully the dealer will be very proactive in assisting you.

Brian's right. There's an easy solution to your problem that will cost you ~$350 and you'll never worry about this again. It's called a PCIII. Buy one, install it and fix your own fuel issues. You can add/subtract fuel in 250 rpm increments and that should be more than enough to resolve your lean condition.

I see no mention of syncing the throttle bodies, was it done? I have discovered the TBS is very important to keep on top of with he DL1000
