Does the cough get better?

[handyhiker]

I have an 07 DL1000, ever since I picked it up at the dealer, it has a cough that comes and goes. The bike might run great for 10 miles, then misses/coughs. This may go on for another 5 mikes. Seems to be the worst between 2500 and 4000 rpm. I only have 300 miles on the bike and I really can't tell if it is getting better as the bike breaks in. Any experiance on this with a new bike? Should I take it back to the dealer? What should be looked for on the bike? Thanks in advance.:confused:

Absolutely, take it to your dealer, and if they are useless, go to one that someone on this forum recommends. With only 300 miles it's still their issue. This seems like something out of adjustment, not the norm. Almost sounds like a ridiculously out of adjustment TBS. The bike will smooth out as you get some time on it. Not worry, this is easily rectified, and you will love this bike.

See...I told you guys that they "still" haven't fixed the lean, stumble, cough issue at low RPM's. The big dog is choked to death, to simply try and meet the EPA specs.

I would take the bike back to the dealer, and tell them to either give you a new ECM, or reprogram your computer with a Yoshimura box. It will not go away by putting miles on your bike. It might get a bit better as your air filter gets dirty, cause it isn't flowing as much air.

It is not the nature of this engine to do this, so don't let them feed you that line of crap. Properly tuned/adjusted, the big Strom runs fantastic. ALL dealers have been made aware of this issue...and they are being told by Suzuki, to work with the customer.

04' owner with hiccup probs myself. I just got my throttle bodies done at the dealership which was going to fix this common V-strom problem but did not. I can't believe that Suzuki has not fixed this problem yet(07'). Make the dealership get the bike to run right it's brand new.

What's this "cough" like?

My '06 has a hiccough at precicely 2800 rpm, but only when it's being held there. If I accelerate through it, there's no problem. It seems like a miss on one cylinder, as though it just doesn't get enough fuel. After putting 4000 km on it, I notice I have a tough time making it hicough now. So maybe, as Big B suggests, I should clean my air filter. ;) I've also noticed it does it more with higher octane fuel. 87-89 seems to be its preferred fuel.

From what I've heard, this is a common occurence with the 1000. If yours is hacking and wheezing all over the place though (2500-4000 is a broad range), you ought to get it looked at.

Others will tell you you're crazy for ever running it below 4000 rpm. I often wonder how they take of from a stop.:???:

Hey Larolco,

Your 06 is doing the exact same thing mine did very early on. The 2800 rpm hiccup, although mine only did it on deceleration with little or no throttle, in 3rd or 4th gear. Never under throttle or coast. When it happened, I would self TBS it and it would run fine, and no hiccup for some time. Now with 7700 km on it, it hasn't happened for a few months.

I will get it back to the dealer. Just to conferm when it happens and what it is. When I am holding steady throttle, at anything under 4000(and sometimes just above)the engine seems that one cyclinder pops or misses. The bike shutters and then maybe ok maybe not. Usually once it starts doing this it can become very bad, I have to down shift and accelerate to get out of the problem area in the RPM range. I think I also felt what seemed like a droped cyclinder going down the freeway. The bike lost power and started running rough. Gave more throttle, the bike accelerated and smoothed out. This also was around 4000 RPM.

[tmcgee]

Oh jeeeeze....it gets a little chilly and the big strom starts coughing?

:roll:

[Heavy]

Take it back to the dealer to have the symptom documented at least. Put a bunch more miles on it and it'll smooth out. For the first while my '06 would stutter, backfire through the intake, stall and do all manner of ugly stuff. Now, 10,000 miles later, it runs very well. I'd say I get a little intake burp maybe once in 2 months. All I've done to it is add a K&N air filter (which should make the lean running worse), synch the throttle bodies and ride the snot out of it.

[Kawidad]

Be aware our fine friends to the north and elsewhere, you have a different ECM map than we in the land of the EPA have been saddled with.

Handy, what you are describing is very common on the liter bike. Some have it worse than others, some smooth out with miles on the clock and some do not. I would work through the dealer or another dealer if that one is not willing to work with you on the problem. Once the warranty period is over and if it is still doing it, then there are several fixes available. Just read the forums and you'll see. Just be very careful to not void your warranty.

Really? Do you guys run leaner? I wasn't aware.

Yup. 13 or 14 inches so far. I'm in the process of installing a plow on the Vee. I can't seem to find the how-to thread on that installation.:wink:

[Mortaine]

I use Benadryl, for sneezing and Vicks cough syrup in my V when its starts to cough and sneeze. Works everytime, so far. My bike is such a sissy about cold weather, I have to threaten to ride the BMW just to get it out of the garage sometimes. LOL

[jomawan]

For what it may be worth or not:
Check the throttle cable synchronization. The owner's manual has instructions for doing this.

[Heavy]

He's in Ohio, not Cali. He should have the same map as us.

[handyhiker]

From what I have read on the forum and can decifer, The ECM may be the cause of the stumble:confused: If I install a TFI box, Will this let me tune this problem out? Or do I just need to get a new ECM that doesn't act up? Then what happens when I repipe? :?:

I will still take this back to the dealer, but I guess I would like to know what to tell him MIGHT be wrong. I hope he will listen to me and at least check what I suggest.

Tell them to hook up to a Yoshimura box, and remap your ECM. This almost always takes care of this running issue. If they don't have a Yosh box, tell them to replace your ECM under warranty. If they do have a Yosh box...increase fuel 1.5% at idle and 5% at BOTH low and mid rev ranges. This setting should allow your bike to run fine with new exhausts.
Or you could buy a PCIII or Techlusion DFO unit, and not have another problem.

Also....300 miles isn't enough mileage to warrant going to the dealer quite yet IMHO. Run a couple more tanks of gas through her "87", and get gas at top tier stations. Things "may" smooth out a bit after several tanks of gas have been flushed through. The factory coats the inside of tank with an anti rust agent, that I understand may cause some rough running for awhile. My bike did the same as yours for almost the first 600 miles, then things got a bit better. The cough/stumble, surge happend less frequently at over 1500 miles, but it was still there. I balanced my TB's, took it into the dealer and they remapped me with a Yosh box. I now have just under 9k, and my 1000 runs great. Make sure your idle speed is 1200 +/- 100 rpms too.

These bikes are very lean due to EPA regs. I live near Dallas 600 feet above sea level. Depending on where you are altitude wise this may or may not be a problem. My K6 did the same from new to 1000 miles when I reprogrammed the ECM with a Yosh box. After the Yosh the engine was a totally different engine. The cough, stumbles and stalls were gone. If your dealer is useless like mine get on the Yosh box list and Yosh it yourself...

Thanks for all the feedback, I will post what the dealer tells me as I will be there today. If he doesn't have a clue, I will get on the list for the yosh and fix it myself.

I doubt it will, but will this reprogram void the warrenty?? Will the dealer even know I did it?

1. Doubtful
2. VERY unlikely

They know that it is a problem....better to ask for forgiveness, than permission.;)

[handyhiker]

Well, I took the bike in last night and droped it off at the dealer for repair. I was quite suprised with the reaction I got. I talked to the service writer and was explaining the problem, I told him that I belong to a few V-Strom groups and that I had asked the group what might be wrong with the bike. I also brought up the fact that in todays dealerships, having to deal with several brands and many many models, I understood that they could not be very bike specific on trouble shooting. I told him that the first thing was to check the TBS, and the TPS. Then cable sync, and finally remap the ECM on the bottem end because it is set too lean from the factory. He kind of gave ma a strange look, like he was unsure what I was talking about. The good part of the story is he let me write the repair order and list the checks to be made. He was a young guy(19ish)and I don't think an actual tech. They are suposed to look at it today and give me a call. We will see what happens.:rolleyes:

[handyhiker]

I have the bike at the dealer for repair. Thanks to all for the info. The bike was just too nuridable to try to get any more miles on before I had to have something done.

[GONE14S]

I think that if I had a 19 year old in serv. walk up to me and want to write a work order I would slam on the brakes. When he asked me to write the work order I would lay rubber getting out of there.......but to each his own, but than again I build and rebuild bikes myself.

[Scarecrow]

+1 on laying rubber...if a shop can't put a knowlegeable person out front, then I (you) should take your business elsewhere. In the IT World, it's the "Chimp-with-a-Phone" approach to technical support all over again.

Late in the game for a "me too", but I have an '06 which did the exact same thing. Mine was also unridable; I brought it in @ 600mi and said "fix this thing, else take it back" (and here's $500 down on the new Triumph Tiger). Luckliy (pocketbook-wise), all ended well in Stromland...

Nutshell: the bike was setup wrong; TBS showed it was off; got remapped (just in case); then it was at least ridable. Secondaries were later pulled and now it's the cat's a*s. Petrol consumption went from 36mpg to 44mpg. YMMV. Once I get a chance to drop a tooth on the countershaft, it will be right about where I want it to be.

I still think there's a rough spot between 2800-3800rpm, but like many of you, I rev right past that and have learned to accept it. My Sprint ST has a flat-torque spot @3300rpm and I use it as an indicator of my rpm w/out pulling my eyes of the road. It's kind-of like loving your mate; not perfect, and you end up learning to love the imperfections anyway...

[randyo]

I'm at about 325 miles now on my 07, it has "caughed 2-3 times maybe and right at 2800-3000 rpm when I am going from off throttle to on throttle and only in the first few miles of a below 32° ride (but after the engine was warm per the gauge)

I'm not overly concerned yet but I will let my dealer know when I bring it in for first service

[handyhiker]

randyo, just for the sake of trying it, try a different brand of fuel. This is worth a shot as mine is picky about brand.
