K1200R probs :(

Hi all just registered so newbie here,
my R started running a bit rough a few months back , running not as smooth as it use to so took it to my local bike shop who straight away diagnosed as plugs , so plugs where changed and it seemed good for a few days , it then was running worse than ever , its best described as an old car with damp ignition probs , it runs fine on high revs but pulling away its seems to have a bit of a stutter and once ya get over 4k revs it seems fine , even after a long journey its no different , took it back to the bike shop and after sat on the diagnostic machine for quite a while he tells me no errors and it revs soo smooth and crisp .Not the same story while driving it .
the bike has the usual rattle on start up (cam chain tension) so i was wondering if it was possible if the chain is quiet loose could this throw out the cam timing ??
i know theres a big issue with the cam chain tension on K bikes so i asked my bike shop to replace with a new hydraulic tentioner , after they spoke to our local bmw dealer they advised him to leave it alone and do not fit a new tentioner , this seems very strange to me
can anybody shed some light on a possible cause ?? could it be something as simple as a faulty plug thats just been changed or am i asking the impossible.
Bike is a 2006 model and has done 22k miles.

My seat of the pants, free internet guess is ignition coils. They seem to fail more regularly than they ought to. They do not throw a code when they go, they just strand you. Try using an infrared thermometer on the headers when it is idling rough to see if you can locate a cold one. Another method is to just replace them. They're about $170 each, so not exactly cheap. They will strand you if 2 go out at the same time. I know this.

Thanks i had thought of a coil pack but i figured this would throw out a error code so good to know they dont , will order 1 and try that , gonna be awkward to figure out which 1 it is but i'm sure i can figure something out thanks again .
will keep you informed if the problem gets resolved .

Good to hear that you got it sorted. How many did you replace? Mine were the outside 2 cylinders, 1 and 4.

Hi i found 3 on ebay in germany , shame he only had 3 but i took the risk of changing 1,2,and 3 , i figure 2 and 3 take slightly more heat than 1 and 4 , and although i still have no idea which coilpack was at fault she's now running like she use to , so happy days

she away for the winter now ,but soon starting to take her apart for a full repray and powder coated wheels.
roll on march / april when the sun starts to shine again.

still aint decided between Matt Black or High gloss Black

I picked up a 11/2005 build K12r today and it went like the clappers until the fuel light came on and I was riding suburban streets.
It was running rough at lower rpm/gears but once I filled up it seemed fine.
Any clues to this one?

My 2005 K12r Hates slow riding, it is hard work keeping it smooth, bought a brand new K12S in 2005 which was equally difficult to red slowly, so much so I got rid of it coz I needed to commute and needed something smoother, 1200gs done the job. Mind you I love the smoothness once the K gets moving, they're mega quick ain't they.
