My 06 K1200S feels like its back to square one again...

I had the new airbox fitted which seemed to help the bad bucking on throttle application but it seems to be back again. Its a fecking pain in the arse when filtering and riding round roundabouts etc... I also seem to have lost engine breaking so to speak, when letting off the throttle its like its still applying some?

The engine breaking I can handle but the bucking is really getting to me. I am not sure if i have an issue with my shaft drive but it seem whenever the power is applied it double takes almost, like burrp, burrp and the bike judders?

I got my '06 back after a new air box with 13.2 firmware, new cam chain, new irrium plugs & new rear brake lever - But a surprise of new problems from the new 13.2 firmware - ( I got Clear Alt. rear brake - LED ) so when I touch my brakes I get a LAMPR & a yellow trianglr warring on my dash :yeow: - But the stock brake light is fine - So it's something with the resistor to the rear brake light - But the I still have a LAMPF that the new firmware was to clean up - So my bike's dash is flashing christmas tree - if I use the directionals & brakes :rotf:
My wife said the bike is louder as well - I think it's because of the weather here - ice & snow and I have not been out in a while to have her hear me comming down the road :D

What firmware you got? I still can not tell yet - my bucking happens in hot weather or in city traffic - before.

I have 13.2 also.... It's weird, I had a run out to the dealer a while back, no traffic, open roads.....lovely, bike felt great. Whenever I am commuting the bike is crap. I've bought it up with the dealer and they just seem to give the line "thats what they're like, bad around town". The salesman knew I was commuting, never would have bought the thing if that was the norm!

If you have the option to install a Power Commander III in the bike, do it. I know you shouldn't have to, but it sure solved a lot of bike fuel problems to include my 2007 KS.
I keep thinking about a PC II but the problem is the bike is still under warranty, and I am thinking of continuing with the BMW Motorrad warranty after its expired :-(

I understand that, but the PC would have no effect on most parts of a warranty. I'm not sure what the PCIII would have to do with most anything under warranty. I'd ask your dealer what he thought. I had my PC installed at about 25K miles. The bike was not safe or fun to ride the way it was.

If the bike was constant grief, I'd do the PCIII knowing it would cure the ills and just not say a word to dealer, regardless of the warranty. There should be no reason for them to cancel warranty. I installed a Dobeck/TFI on my new '08 R12R last year and the warranty was never voided... they couldn't miss the module sitting under the seat when service checks were done either. It just was never a big deal to them.

Its weird, i did bring this up with a dealer.... When I mentioned replacing the suspension lower plate they were like "if something fails as a result of it would be void" but when I mentioned a PC they were like "that WOULD INVALIDATE the warranty"!

Interestingly I thought I'd add to my problem mentioned as now the bike is sometimes stalling when I start it up in the morning. Start her up, go back in the shed, helmet on etc come back out and she's not running. Also a couple of times the revs have been dropping right down and staying there for ages like its trying to cut out.....?

I hear you, but I would get the PCIII and forget about the warranty issue. Fight that battle when and if it ever comes up. As it stands now, your bike sux and it is not fun. The PCIII will cure that. Why live with a crap bike when you don't have to?

According to today's Power Commander website, the PC III is no longer available for any BMW... they show a PC III EX version and nothing available either.

But, the PC5 is now available for K1300S/R..... and not available for any K12.
Not being familiar with the product, I don't know what these apparent changes mean for K12 people. Maybe the older version of the PC III can still be obtained; if not, looks like Roundy and others will have to go another route.

Anyone out there who can add clarity on the matter?

So just had a call from the dealer....they've found the air filters to be very very soiled and also found some oil and water clogging a breather pipe. She's not that far off having the air filter replaced (not done at the 18K service apparantly)...

Be interesting to see if they find anything else and if not whether it still has the problem.... They've not replicated the fault but I don't know if they even tried seeing as I sent them a video of it happening....

I hope that fixes your problem. I will add that my dealer could not replicate my problem either until I showed them how to fix it. They replaced the ECU to a BMSK-P and replaced the air box, and the plugs, but the bike still stalled and had a rough idle and rough low speed, and that hesitation at about 4,200 rpm. It wasn't until the PCIII and map that the problems went away.
Good luck

Well they've not managed to replicate the fault, but they didn't try before sorting the filters and clearing the breather. The service guy did say they were awful, not in a "lets just replace them kind of way". They've been testing her every morning too so hopefully thats that issue fixed. Won't know for a little while though as in the diag processes they were doing they found a faulty left indicator switch assembley, they have to order the part from Germany and they said it can be 7-10 days!! :wtf: Well at least its a week off the wear and tear on my own bike and the GSA they've lent me is good fun, bit too tall for me though even with the low seat conversion it has!

Got her back on Friday evening as the part arrived quicker than they thought! First impressions are wow, what a difference! The bike feels sooo much smoother, none of the jerky monster it was! It will be interesting to see how it goes once i've done a commute on her but I am sat on a train bound for Paris right now so it won't be for a little while.......watch this space!

I am usually fairly quiet and have been reading and reading the many posts on the poor idle and stalling on the K1200R and S. I had never experienced either of these issues in 16K of enjoyable riding. In the past week we in Ontario Canada have been having a bit of a warm spell. Therefore some early riding so I was shocked to experience the change from one day to the next both stalling at poor idle. It was time for some new skins, so I paid a visit to my local dealer and had them install the tires at the same time I asked my trusty technician (not the “customer intake personnel ” you nervous advisor)to Flash the bike with the latest soft / firmware. I can state that three tanks of gas but very bad gas mileage the bike did not stall, not once. But the poor idle remained; she would idle between 1480 and dip as low as 720 RPM. This is from Rapid Bike 3 software and a laptop not looking at the tach. The poor gas mileage was concerning 220km to the tank a distinct odour of gas remained but no stalling. So the reason I did this today is that I go in for a spinal decompression surgery tomorrow so I decided to get to know her again you know get personal get all up in her business :dunno: , I removed the airbox and removed the idle control valve that sits in the middle of the airbox, after all that work I called my BMW Technician and asked him if he could tell me if BMW sells “idle control valve” after a bit of searching about 5 min. he says that he has a part number for me, great 13717705442 with this information I thank him profusely for his assistance in this manner, :clap: I carry on to call the PARTS department and inquire about this part number, after having to repeat it three times I was asked what is it? I replied it is an “Idle Control Valve” to which he replied, “I think I just saw a bulletin on that” :yeow: , I was caught like a deer in the head lights, I thought “one that reads” that’s a good thing, he was also able to inform me that it is a part that has never been sold in Canada and that BMW Canada has not validated that part number at this time, so that being said he is unable to even give me a price and I assumed surely there is no hope in hell of getting an ETA. :confused: Well now for the philosophy I do believe “whatever man has put together man can take apart” and hopefully reassemble without any extra parts :popcorn: . After some studying the part/assembly :confused: , I concluded that it is a motor that spins and moves a plunger up and down allowing air to pass through the valve in various degrees. I also noticed that the height that the plunger set within the valve appeared to be too high, but how pushing down on the plunger proved useless and turning did not set it lower either although there appear to a threaded shaft that runs into the motor. Ok to shorten up the story reassembled the bike; it started but would not idle at all. OH NOOOOOOOOO disassemble again and tap the plunger firmly but not too hard and the plunger dropped about a ¼ of an inch into the motor, reassembled the bike and the idle is at 1100 and varies about 85 to 85 rpm either way. Very acceptable to me. So in conclusion I believe that there is help in the soft/firmware for stalling and the idle fluctuating is due to the idle control valve where the plunger that controls the air valves somehow works its way out of the drive motor which throws it out of specifications.
Now I wish I had taken the time to take pictures of all this but I was determined to get it done before I have to take it easy for 6 to 8 weeks. Hope this helps someone.
Keep the shinny side up :teeth

So its been about a week since I got the bike back and its back to square one :-( The bike has been stalling on warm up (in fact did it the first day I rode it from getting it back from the dealer) and went out for a ride today with the other half on the back and it ran like a bag of nails. It surges, it bucks, it sounds like its mis-firing etc. You can hear everything rattling around when its idling, its just no fun to ride. I've really come to the end of my tether and I am going to get back in touch with my dealer. I am not sure where else to go with them now other than threaten legal action.

Does anyone have an email contact for BMW UK that I can CC into my email?

So, Roundy, with a bike that is 4 years old, do you have the facilities and tools to follow the steps Ajeninc performed to ascertain if that is the problem with your bike's idle? Admittedly after all your trips to the dealer, the issue should be solved, but it seems you might be beating a dead horse and their efforts do not seem to be paying off. Time for a PCIII and a tap or two on the idle control valve? I only have about 2500 miles on my S, but am scheduled to drop it off for the new software and switch-gear replacement this week. First my ESA control disappeared as the switch now does nothing when depressed, then two days later, no turn signals. The typical 1300 stalling has only happened a couple times for mine, and was very mild, but getting the Recall notice prompted me to get scheduled. Whichever way you go, good luck and good riding.

Quick follow up to the idle control valve. My dealer has emailed me the price in Canadian dollars as $240.09 A special order part so I have to pay in full prior to part being ordered. :boom: The part should come in a week after being ordered. BMW Part# 13-71-7-705-442.
I think I am going to see how long my smooth idle last before investing in this part when the tap has at least temporarly fixed my rough idle problem.
Hope to give more extensive information on ride improvements ie. gas mileage improvement ect. when the surgeon gives the all clear. :phonecall

Go to www.chicagobmwmotorcycle.com. They list this part for US$137.30 and if you call them on the phone, you get 20% = US$109.84. Sorry, can't resist: don't support BMW Canada thieves!

I know the bike is 4yrs old but it was sold with warranty. Most of my issues have been with the bike since day one and I've never been 100% happy they've been resolved. I don't have the time to take her apart but more to the point is why should I when it's under warranty!

It was weird as when they replaced the air filter and cleaned the breather hose out it was a lot better, but it seems to have gone back to square one. I wonder if part of it is them resetting the ECU and it running better as its lean until its worked itself out?
