2010 (DOHC) R1200GS Engine Vibration
I am writing in regards to a problem I am having with my 2010 BMW R1200GS. Have any of you experienced a high-mid frequency vibration isolated to the engine with a loss of power starting at 3700 up to 8000 RPM?
The base line is an engine that has the throttle bodies sync, valves adjusted and reprogrammed engine control unit by the dealer. This bike was very smooth through this revolution range up to the 24 K service. Now both hands and feet become numb due to the engine vibration that was not there prior to 24K. This bike did have a recall performed for the camshaft sensor reductor replacement.
The local dealers are stumped and their only answer is keep riding it and perhaps it will get better. I would appreciate any help/advice to get the bike to run as it use to prior to the 24K service.
Right now I have two options, ride it like it is or sell it!

Thanks All for your help on this problem. I have experienced twice a cut-out or misfire when accelerating in the higher RPM range (3700-8000). Perhaps this is problem you have described that it may be the stick-coils. I am going to examine the sparkplugs and coil connectors for dirt/carbon burns and clean and replace (SPs). However, how do you test a stick-coil and to what specification? Aregular coil I can test with load using an old SUN machine, but a stick-coil, I'm clueless. Is this a BMW "Plug &Play" technique utilizing a new and known "good" stick-coil"?
I am looking forward to your recommendations.
2010 (DOHC) R1200GS Engine Vibration "Un-Fixable"
Took the bike to the local Beemer master and he was unable to figure out what is causing this vibration. It seems that everyone seems to think it is ok for your hands and to go to sleep with in 15 minutes of riding over 4000 rpms. If this had been the way it had always run I would not have bought the bike. I had a great 24 k miles on this bike and as long as I keep it under 4000 rpms the engine stays smooth. I guess BMW can't fix what they make, unfortunate.
Thanks all for sending your recommendations this helped troubleshoot and eliminate possibilities. Something has change inside this engine/ECU but unable to identify it.

Taking the bike in for a final reflash of the whole engine ECU. If that does not fix the vibration the bike goes up for sale. No fun riding electric sanders that numbs your extremities. I will let everyone know the outcome. Unfortunate that my dream bike became my nightmare bike!
Thanks for all of your recommendations.
Stump the Dummy! Still has the Vib!
Wanted to report back after so long to let everyone know the latest result. Took the bike to the dealer and re-flashed the ECU, checked the valves (In mid-), Re-sync TBs, new sparkplugs, new alternator belt (new Part#) and result was: Vibration still there start at 4000-6000 RPM. Had bike checked at another dealer same problem. Took to non-dealer BMW specialists, same problem. All three said valves were set correct.
Enter the GS911 and pro-motion manometer. After re-sync of TBs still has vibration but less intense. Re-checked cable slack (.5-1.0mm). Left side off, reset to .60mm. this brought the butterfly to the complete stop position. Reset slack on right side to complete stop (.6 0mm). Re-synced TBs using GS911.
A reminder: when you get to the end of the Re-sync and it says to turn off the engine right after it says un-locking the steppers, "WAIT FOR IT"! Listen for the steppers to come back on, the engine will run smooth. Then shut the bike off or you will have to do it again.
After the re-sync with the GS911 the vibration was still there less intensive but still enough to put your hands and feet to sleep. The range was at 4000-5500 RPM in any gear (the Sweet spot!)
Next checked Coil sticks and head temperature, all still good. Steppers were good and O2 Sensors as well. Pretty well stumped! The idle is near perfect which is determined by the valves but may still break open the valves and check one more time.
I have close to 33K on this bike and the first 24K was great, but now it just isn't fun anymore. I will update if any new developments.
