Although I initially reported that 7.0 solved all fueling issues on my '06 K1200S, further riding shows otherwise. Current mileage: 8630, on 7.0 since 5948 miles.

The episodic, jerky off-throttle behavior still sometimes happens, but is less severe -- I'd estimate about 1/3 to 1/4 as intense.

It's most noticeable in 3rd gear sweepers around 50 mph, when you're gently rolling on/off the throttle. Normally such throttle transitions are very smooth and linear. When the problem happens, gently closing the throttle at first causes a smooth reduction, then power suddently drops to zero.

Problem comes and goes. When it happens, it's consistent for a period, say 1 hr. Shutting down the bike for 5 min always makes it go away, sometimes for 10-15 min, sometimes longer. Sometimes if I continue riding, it goes away by itself.

It's just like the 6.0 behavior, except less severe. 6.0 (on my bike) was borderline dangerous, the behavior on 7.0 is somewhat irritating but I can ride around it.

Problem happens with both stock intake/exhaust, full Akropovic exhaust & EVO intake, with and without O2 sensor connected. Have done TPS and ECU resets multiple times.

The fact it got better with 7.0 implies a non-physical cause: fuel injection software, not sticking throttle mechanism.

According to this thread, 7.0 incorporated sequential shutdown of injectors when closing throttle: http://www.k-bikes.com/forums/showthread.php?t=7168.

Has anyone else who had significant closing throttle problems on 6.0, and who upgraded to 7.0, experienced this?

It's definately better than 6.0 , but getting smooth on/off throttle transitions are still a bit tricky with 7.0. I've solved mine though - bought a CBR1K and just use the S for highway superslab riding.

How sad..

...When do you think BMW Motorrad will be contacting the owners of 2006 K1200Ss about 7.01X or whatever they are working on as part of a "recall"? It would seem that a company of their "ultimate driving machine" reputation/credo will do something PROACTIVE on these issues. Agree?

While it seems that way, Motorrad's current policy on the 7.x update is it's not mandatory, thus not a "push"-type recall. It's only done if customers specifically request it.

They may view 7.x as an interim fix, and could be awaiting more data before issuing a more final fix. Maybe then they'll do a recall. This is a common procedure in various industries, from software to airplanes to automobiles. Just speculating.

However the experience with 6.0 illustrates the danger of prematurely doing a recall. Imagine if all KS and KR bikes had been recalled for a mandatory 6.0 update. It would be quite costly, didn't fix the problem in all cases, and could have inconvenienced many owners who weren't having problems.

Hi to all, I should say this is my first post and I'm getting straight to the point (almost) !

I've been lurking for over a year on this forum reading all of your posts with great anticipation.

Unfortunately, there seems to be one major negative, and its made me balk at purchasing - constant posts of problems with what seems to be the engine management software throughout the history of the bike.

To be honest, being from the outside not owning the bike and reading every post, its like tossing a coin whether luck is on your side.

Without meaning too offend is the community being overly zeaolous ? (I can understand this given the purchase price.)

I've tried to be objective ( I know, sometimes thats pointless), its a great bike except...there have been so many posts I've read over a long period about this subject.


Regards to all

Richard

PS. My background - 41 yrs old. By no means a 'gun" rider (no pun intended) just love that feeling. I've ridden dirt bikes, Kwakka Z500's & 1000's, GX1100's, 650 Dakar (the latest toy) and I've dreamt about the K1200S for a long time as I continue to 'mature'.

turn off throttle and revs stay high

have the 7. whatever the last one was. Just did 375 NH today and IT IS DANGEROUS=not the roads, THE BIKE going in for repair-1st issue 12,000=fine shape as the rain washed the roads=little salt or sand,did slide front end a few times.This Hossack front end is increadable. The bike mags almost dismiss it but as one puts miles on and learn to feel the feed back, sutble yet there and very readable. And the front end is so stiff, totlay different from sliding tubes, you can "push" the front, and toss this bike around like a big dirt bike almost. FUN

Gunnster, if you want a K1200S, now is a good time to get one. Most of the fueling problems are solved. Most of the posts you've read concern problem reports before version 7.0.

If by "the community being overly zealous", if you mean overly sensitive to this problem, the answer is definitely no. The fueling issues were so bad, the K1200S was lambasted by many independent reviewers when it was first released. The bike was pulled from production and BMW re-designed the injection system.

Unfortunately it still had some issues upon reintroduction. The degree and frequency of these varied from bike to bike, exactly why is unknown.

But most of this is "water under the bridge", as the current 7.0 software fixes most of the problems.

On my particular bike 7.0 was a big improvement and at first I thought it was perfect. However many further miles show there are still some intermittent unresolved issues, but much less severe than at first. I haven't heard any other owners report these, so started this thread to solicit feedback.

The K1200S combines long-haul comfort with sporting ability the way few bikes do. If Honda made an updated more powerful VFR or an updated ABS-equipped Blackbird I'd consider those. However they've abdicated that market segment and act like they don't care, so that decreases our choices.

The Kawasaki ZX-14 is another possible choice -- very refined engine, but no ABS, no factory luggage. The new upcoming Concours 14 (sport-touring, shaft-drive ZX-14) looks good, but is more in the FJR1300/K1200GT class.

Gunnster - I think you have hit the mark with many forum posters being "over-zealous". I try to look at many of these posts objectively though. What type of people read/post on forums? Of those, how might BMW enthusiasts be different? More picky? Less?(ha, doubt it)

I also think that there are lots of K1200 (S/R/GT) owners who DON'T post to forums, who might start their bike up, hear a strange noise, take it to the dealer, get told "it's normal", accept that, and go about their day. Those poor, uninformed, happy bastards!

I just turned 40, ride moderately aggressively, enjoy the occasional track day, and love the hell out of my K1200R. I don't hang out with many BMW people because, frankly, I don't quite fit the demographic. I'm sure one day I'll trade leathers for a Dririder, a Shoei for some flip-face job, grow a beard and get a pipe, but not yet!

I agree with Joema, most of the big problems have been cured, we're just left with a few quirks. Embrace the quirks and GO GET THAT BIKE!

while I agree some what with BMW people

and the new type BMW attracting non-BMW people like myself=I'm not considered PC by any strech. I WOULD NOT BUY THIS BIKE AGAIN if I knew about the fuel probs. Having the throttle hang whenyou let off and the revs stay high is a DANGEROUS BIKE. Other than that I love it, It's like a beautiful built blond chick that's got bad herpies. DUH>

Did about 150 mi today -- ran perfectly the entire time. Totally smooth carburetor-like fueling. Don't know what triggers the periodic jerky on/off transitions. At least on 7.0 they are infrequent and fairly minor, even when they happen.

Yeah Yeah we know, you like jap bikes better. Just get rid of your KS and you won't have anything to complain about.

p.s. My k1200S goes up for sale in the spring for a KTM or Husqvarna dirt bike - if they fix the issues by then, it's a keeper, otherwise it's like a girlfriend who's good in bed, but can't be trusted.


Later Bros...


o'h and if you ain't figured it out by now, there ain't no room or no place for a pair of slippers and and a pipe in my tank bag!

That's the old dude's BMW era - not mine!

Well, I can only share my experience, which has been love/hate. The bike is absolutely drop dead gorgeous and the suspension is awesome.
The overall build quality is excellent.

The fuel management in my opinion is horrific - at least on my 05. I drive 150 miles round trip through heavy traffic and it's not pleasant. Between the sputtering /surging and the farting/backfiring...well, I just expected more - let's put it that way.


I will not recommend the bike to anyone, until BMW steps up to the plate and makes everyone happy, but it has potential - if your willing to wait for BMW to
figure the problems out and fix them, then go for it.

Yea Dickhead...if the K1200S would have been right, I wouldn't have had the urge to buy a Honda, but it wasn't, so I did.

Tisk tisk....so touchy. I didn't mean it as an attack, kind of a jab (meaning just a friendly joke) so the dickhead remark was not really needed. It's cool though, I like jap bikes too. I have an 05 and don't have any feuling issues. Yes it's a bit jerky on low revs, but nothing that bothers me too much. Anyway, sorry you are dissapointed with your purchase, hope you are happier with your next bike.
