New 2013 GS falters at steady speeds

[Zardoz]

I posted this on another forum 1 july. It turns out I'm not alone. The problem is still not resolved...

____________________________________________


I just got my 2013 R1200GS two weeks ago and am having problems already.

Whenever try to maintain a steady speed the engine begins faltering and hesitating. It starts off slowly and gradually increases until it’s like running on fouled plugs. In addition, when releasing the throttle or coasting on a slight downward incline the engine clearly misfires or falters.

When I brought the bike in for the 1000km first service, they downloaded the latest software and it helped but it is still faltering, particularly when I release the throttle.

I am thoroughly bummed and am wondering if anyone knows about this problem or has experienced the same, whether or not it’s a new GS.

Update 1 august:

The dealer has run a diagnostic and found a variation on the stepper motor. He did not replace it and the report has been kicked upstairs.
I believe they recalibrated it or some such nonsense.
While the situation has improved I still feel the engine faltering at steady speeds.

I noticed something today that was of interest and I like to get you other GS owners to try this. When I came home after a ride today I tried to hold the engine speed at a steady 2000 rpm while at a standstill. It was impossible.
The needle absolutely refused to stay at 2000 and fluctuated above and below the mark. I was rock steady on the throttle and not trying to compensate.

I know this is without load but every other motor I have ever had has been able to maintain a steady rpm rate at standstill.

Could someone else try this and let me know if their tachometer shows the same fluctuation?

Looking forward to feedback. BTW I see other people are complaining about "surging". I believe that is the same problem as I have only with a different adjective.

Second update: I ordered a Booster Plug to see if that resolves the problem.

Mine does that - I just assumed it was normal behaviour. I have to say I like the loud crackles\popping\banging reverberating around a small closed in village...saves me having to buy a louder can

....but if its not normal, I suppose I ought to mention it to the dealer

Now Zardoz, yer English is impeccable ...

But a little tip for you ...

Avoid talking about being bummed

Welcome to the site ...

Quite.

Bummed and your bike doesn't run right.

Not your day is it?

Hehehe, it took me a second but I finally caught the reference to being bummed..

Interestingly mine has started to do this after 1300miles. Riding through traffic on marginal throttle, say at 30mph in 3rd at 2500 rpm, the engine seems to misfire and hunt as if it's running out of fuel. As soon as the revs increase it's seems fine. Will be going back the dealer to sort...

Normal Gs WC has a very light flywheel which makes it very 'racey' & hard to stabilise rpm below 3000rpm.. But when u give it gas it flies.. (Makes me use the cruise control more often)
The GSA WC on the other hand is tame in comparison, it has a heavier flywheel so more stable, but feels less nimble off the mark..

Now then guys & gals, I really LIKE the way the new GSA works, but the remaining bit of hooliganism in me is saying put up with the GS WC for a few more trips before I trade up to the more 'sensibile' GSA WC

You will find it is probably running insanely lean at all but full throttle, just like the model before.
I imagine software is currently being written outside of BMW to reprogram these poor running issues.

I had something similar but only really noticeable at town speeds in 1/2/3 gears

Now appears to be fixed (almost)

I agree, a richer mixture will calm things down a bit..
There are ways to richen mixture cheaply but loose out on the amazing 50mpg

I haven't noticed this on my 2013 GS and I am now up to 13,500 miles - I am not on my bike today but will try some constant throttle experiments to see if I can make it happen. The only thing that I have noticed is a slight throttle jerkiness around 2,000 rpm but the previous 1200 oilheads were much worse in this area.

Friend had a 2013 most resembling this description and they could not fix it so they replaced the bike.

I posted about this problem last year and reported it to dealer with no joy as it could be character:-( its going back tomorrow, its had the clutch fix which is
better but far from perfect

Often enriching an over weak mixture can result in better mpg as the bike can then pull much smoother lower down the rev range thus allow the use of a higher gear and actually dropping the revs. Apparently the Hill-Tune dyno will sort this issue quite easily, but it's a shame that you should have to pay for a 3rd party to sort out the issue when the bike is under warranty.

All modern car/motorcycle engines designated for road use run leanish.
Thus so to meet current emission regs.
Also in the hope of achieving the extra mile or two more from the fuel burnt.
This is why its fairly easy for joe public to buy a few bolt on goodies and quite easily improve the performance of his machine. Your local engine tuner can make your engine perform as it was designed originally. This usually involves more fuel in and more exhaust waste out,the faster the better. Freer flowing ,less restrictive and more in are the main ingredients. Bmw could easily have their engines running much sweeter and more powerful but we end up back at eu emission regs which dictate how manufacturers set up their engines. Get your motor tuned and it will run perfectly. What ever updates your dealer downloads your engine still wont run as designed.

I have a 2014 GS LC. Have not had any of these issues. Runs perfectly. This one is a keeper. I hope you can all sort those issues out.

I have a 2014 GS LC too and have not experienced any issues with hesitation/surging at steady throttle.

with cruise control , this condition can be easily duplicated and recorded to show to the dealer.
