Have you any slack in the throttle cables?

There is a good article about the DL1000 in the July edition of Ride magazine which mentions the binary throttle response at low revs. However there is no suggestion about how this can be eliminated.

Care to post the paragraph in Question?

I'm curious as my v-banana has developed a real irritating throttle response at 20-30mph in 2nd and 3rd.
If it has two wheels.. I'll ride it.

As my 2016 is new I have now asked the dealer to contact Suzuki about this issue. Basically it is impossible to hold a steady throttle around 2900/3000rpm in the lower gears up to and including 4th. Its either on or off with nothing in between. I understand this is an emissions issue and I suspect that 2900rpm is some form of transition between one map and another but it is a real nuisance that I would prefer to be without.

I hope the dealer and Suzuki can help you out mate. Some of these bikes run worse than others,  mine was a right pig when news. If the dealer comes up with nothing try a x-tre. Made the difference for me, if not I'd sold the bike a long time ago.
There have been some bikes needing new throttle bodies before.
I've also had a sticking exhaust butterfly valve which causes a misfire below 3000 rpm but goes away after 5-10 miles once warmed up, maybe worth a look.  Good luck, I hope the Irish dealers are better than the northern irish, might as well ask our dog!

Porter is well up on this,I too had the problem to some extent,the X-TRE smoothed it out a fair bit.

Thanks blokes... The response I got from the dealer was a pass-off but they confirmed TRE would end warranty so would PCV etc etc. Out of warranty it would already sport full arrow system+PCV and I'd take those STV plates out and throw them in the nearest skip along with plate control mechanism. 2 hours on the dyno, job's a good'one. My sv1000s was daily rider for last 5 years, and those fixed any throttling issues, except me using too much of course.

I'm guessing like the SV this L8 ECU/FI/TB system is fairly rudimentary just running maps vs analogue sensors with mechanical controls and as such a few will need a little fettling to get right for each machine. No machine learning here for 9K eh?

If it has two wheels.. I'll ride it.

If you have any warranty work or service just remove the tre, simple,  never hurt my warranty as they didn't know it was there.  Full exhaust,  pc 5 or fc plus map is the way to go if you can afford it, I could but I'm to tight!

Fitting a TRE would not cause an issue for warranty. (I work in a Suzuki dealer)
It just sends a set signal rather than the variable signal from the lambda and or other sensor.
If you splice into the wireing to fit then yes, but 99% off all TRE are plug and play.

The problem is the spot between 2500-3000, you make any throttle change in that space and its the binary response. I have my dyno chart that shows it, so it is real

https://www.dropbox.com/s/231u1wsl4wgyrf8/big-dipper-small.jpg?dl=0

The solution I have, but haven't fitted, is the 'BoosterPlug', which fools the airbox-intake temperature sensor into thinking it's colder than it is (and makes it work properly). This sensor is used when opening\ closing throttle. The sensor on the exhaust is used when cruising and over-rides the air box sensor, so there is no issue.

As my bike will be going in for 7500 service soon, I'll be asking the lads to fit the BP as they have to lift the tank.... yes, I could do it myself, but as I'll be paying the £300 service I intend to get my monies worth (damn new bike warranty) ;-)
In my defence, she did leave me unsupervised.

Interesting about the air box temperature sensor. Now that You mention it the issue is not as evident when the motor is cooler prior to achieving full operating temperature.

I have a 2016 1000 and have none of the issues you described. So maybe there is an issue bike.

Captain, I asked my dealer 2 days after I rode it home from the shop, he shrugged and said "Euro4". So either he doesn't care or its what he says. What opened my eyes was AndyManCam talking about the issues with his Versys, check out his video (Youtube Andymancam Booster plug), jump to 11 minutes if you don't want to watch his very entertaining install guide (really, he's a hoot) and he describes my problems to a T



I will add that I find it very strange that my throttle cable needs constant adjusting... never had that constant tweak with any of my previous 10 bikes, if it's the throttle linkage, it still needs pulling apart by the dealer at the service.

I think Suzuki themselves would be my next port of call cause that ain't right. Plus I don't think the 2016 bikes were euro 4 compliant. Only 2017 on they lost a little power over the 2016 to make them euro 4 compliant.

Fitted the Boosterplug to my 2016 Veek a few months ago, made no difference  :dl_smiley_banghead:

More than one I can assure You. You are one of the lucky ones.

Plumbit101: check for excessive chain slack and throttle cable adjustment\ throttle twist grip snapping back... I noticed both made things worse, but after sorting them it didn't stop the original problem, but definitely made it less of a pain.

Just found this on vstrom Facebook page.
Concerns 2016 flat spot.

I've just been chatting to Darren the chap who the link was too on face book. His is an earlier model just registered in 2016 so had the old ecu. Paulja is your bike an al4 al5 or al6?
