new strom cuts out/backfires/stalls on pull away

[Oop North John]

So basically, if the engine runs badly, stalls easily, doesn't accelerate properly, get the Fuel / Air mix checked out and sorted.

Running way too lean is an easy way to hole pistons / burn out valves IIRC.

[oddbod]

I couldn't agree more with wunwinglow:

The extra power/torque are an added bonus but were not the reason in seeking a remap.

""After the remap I now have smooth, consistent, controllable power as opposed to rough, nasty, 'just about to cough/fart/stall' feeling it gave before.""

Totally enjoyable bike now and the ferry is booked ready for a jaunt to Bavaria returning through the mountain passes of Austria/Swiss alps.

To be honest there is no way I would have considered riding through alpine passes/switchbacks the way the bike was performing before the remap.

[ziggy]

Like oddbod I shall be off to the Alps in 4 weeks with a standard non remapped bike but I have no worries as mine runs fine.

At the risk of starting a riot I have now come to my final conclusion regarding the smoothness of the engine. I am not suggesting that no one has a problem as I am sure there has been the odd niggle.

So having now covered over 8,000 enjoyable miles on mine I have now decided that the engine runs fine in any of the traction control settings. I like others have noted posts that may suggest that if you run on setting one instead of setting two the bike is smoother as I did and yes I thought that does seem better. Again it was suggested that switching off the traction control was even better and when I tried this it did seen better. But as far as I am now concerned its all in the mind. I have tried all setting's each for several hundred miles each and in my mind there is no difference with any of them and lets be honest why should the traction control have any bearing on the engine running/mapping except when ones loses traction and the system holds back the engine to stop wheel spin in what ever method it should.

The major factor for those bikes that do not run smoothly is throttle bodies balance.

 

[wunwinglow]

Also, make sure you have taken as much slack out of the throttle cable as you dare. Be careful you have full and free movement of the handlebars of course, but I have found this also has a big affect on how crisply the engine responds. I still sometimes get a rev plummit, but after the remap, the throttle cable tweak has had the most impact on the issue I am still having. I still have to get the throttle bodies balanced at the next service, and there is a sensor reset as well I understand, but after that point I'm out of options.

Still loving the rest of the bike however! Off to Espana shortly, which should be great!

Does anyone know how this new exhaust valve on the Veek works? Can it be part of these issues?

[Blade]

Had exactly the same issues with the first Vee I bought back in 2008 and exactly the same response from the dealer, can't find anything wrong with it sir. Found a thread on Stromtrooper and it seemed like it was happening to everyone. A nice American chap Johnofchar, who has since passed away I believe posted a complete how to fix it, including detailed diagrams of how to strip the bike down, what tools were needed and what settings the throttle bodies should be at. So I took this to the dealer and said do that please, Hello presto problem solved. Of course it was still a grumpy bugger below 4000 revs but you just had to ride round it or go down the power commander route.

[oddbod]

Juveco,
I don't know how the exhaust valve works but I've had mine adjusted already. It made no difference.

Tim, I will try adjusting the slack on the throttle tmrw to see if that fine tunes the response further. I have already primed my dealer that if the spluttering/farting/about to cut out is still there when I return from the alps then I will be taking up the issue again.

Its interesting though, that it now only seems to want to cut out after periods of slow moving/waiting in traffic. And this seems to be creeping back more and more regular.

Hopefully putting a couple of thousand miles on the bike next week may help iron out the issues.

Update will follow in a cpl of weeks when I return.

[Sharpy]

If the exhaust valve is the same as the gsxr ones then they do very little other than cause running issues, we just removed them, it had no ill effects. When it's not working properly you do get an fi light though.

[breathnach]

oddbod,
I was wondering how your reflash fix was holding up regarding the backfire/stalling.  I am having the same problem with my 2014 V Strom 1000.  The first thing my dealer did was adjust the throttle bodies which he said were out.  Bike ran well for the 1st week and then started to regress.  Issue seems to be definitely related to bikes backfiring.  If bike backfires and I happen to open throttle at just the right time it's like someone blew out a candle and the bike stalls.  Somedays it's worse than others, all depends on if bike is backfiring or not.
I am considering a Yosh pipe and reflash at the same time so wanted to see how your bike was behaving.
Thanks

To be honest the remap worked extremely well for a few weeks (see Wunwinglow's accurate description of this). However, the cutting out has been creeping back in of late. It seems to happen when riding in slow moving traffic or sitting stationary at traffic lights etc. Last Sun it just cut out whilst waiting at a T junction.

I'm extremely glad I had the remap done as it has enhanced the bike in so many ways (as prev detailed) but I guess this is the start of the ordeal again for me as cutting out is simply not good enough on a brand new bike.

[fear_factory84]

Yesterday night I was at an event here at Rome (rome night run) with my Vee2, 40 km very slow ride (more than 700 bikes in the central streets of rome) very high temperatures with passenger.

The heat from the engine was high,  but it never backfired and no cut offs.

It definitely seems that my bike has not problems for now.

[D0nw0n]

:text-imnewhere:
mine does it too. slow speed or starting to pull away misses or cuts out. I'm trying super unleaded to see if that improves it.

[oddbod]

I've been running mine on super unleaded since the remap.
Might try a plug change as when I checked them last week they were ever so slightly light brown with slight hot spots on the ceramic.

[grimcookie]

Mine has only cut out a couple of times since dealer adjusted TPS and synchronized throttle body's  it performed well on holiday in Spain with temp of 34c shown on dash  and rode it back through France OK its fuel consumption was better than the Honda Deauville's and Triumph Tiger 800 XC we travelled with!!
I do however think Suzuki need to look at fuel mapping  because it is to lean!
Must say not very happy that a new bike had to go in to be set up correctly why wasn't it done at factory..  
And Suzuki needs to sort out their marketing every biker we met had to be told what make it was.....

[wunwinglow]

Mine in for a service, and a bit more exploratory work to try and sort this low revs nonsense. Like oddbods, it has become progressively worse over the last few months, and is a right handful on occasions. I've been lent a new VStrom 650 while the work is going on, and this is one BEAUTIFUL little bike! Couldn't be a more striking difference in engine control, so I am sure there is something up with my Veek.

More news shortly....

PS Spain was freaking great...

[wunwinglow]

Hada message from Candyfloss, gist of which was check the earth connection on the engine! This proved to be the issue with Candyfloss' bike, so I passed this on to Frasers, who coincidentally had been told by Suzuki to do the same, so it appears to be a known issue. Frasers have stripped and cleaned the connections, which were slightly corroded, copperslip and ACF50'd them. Still waiting for new spark plugs for a final check, so I can't report the patient has been cured yet, but I have my fingers, toes and some other things all crossed!!

More news as I have it....

Meantime, another pic from recent trip to Spain. Pete on his FJR and me on the Veek, Mallos de Riglos

[wunwinglow]

Got my Veek back yesterday after its 8000 service, and a general check of all the usual suspects. plus a clean and copperslip of the earth  on the back of the engine. Result? Difficult to say to be honest. It still tried to spit me off on the last roundabout before home, so am setting up a go pro to film the entire cockpit area, and see if I can record a snatchy event on film. or micro sd card.... Ill ride it for a few more days, but it is certainly still a load worse than the DL650 I had on loan over the week end. That was utterly delightful, smooth, easy control, no rev drops, smooth gear change, and it went like stink! Just physically too small for me, otherwise I'd be looking at a swap right now.

This is really really disappointing. I had hoped for a reult like Candyfloss' earth solution, but no. The Veek is so outstandingly good in all respects, this low speed nastiness really is ruining the bike for me. If it comes back again, I'll be looking for something else.

Tim

[Jacko]

The 650 isn't much smaller physically is it?

[wunwinglow]

Well, I found the DL650 just a bit 'titchy' for me; maybe what I am actually saying is I'm a hulking brute!! I'm actually 6 ft, and suffering a bit of middle aged spread, but not excessive... Having had an FJR, then a GSX1250FA, then the Veek, I have got used to a substantial bike under me, and as I said, the Veek is perfect for me in all other respects.

I'll report back as the week progresses.  And maybe post some vid if I can film anything useful.
