Rough idle!

Hello all
My 2014 k1300R recently bought with 12k km
Have intermittent rough idle up to die and sometimes normal,
When its rough there is black smoke also.
Previous owner have just put new spark plugs,
My mechanic saws the plugs is not firing good.
Installed new plugs and problem is gone for 1 month ( 500km) and recurring again now!
Now he sees that the problem may be bad ignition coils OR may be something related to excess gas in combustion chamber that lead to premature spark plug failure.. Or may be oxygen sensor.!?
Gs911 is clear for faults.
What do you guys think??

Hi mate,

I had this exact same problem with my 2009 K1300R. Idle up just randomly become rough and then return to normal.

Turns out the electric connection to the ignition packs can quite easily come loose and result in the cylinder shutting down. The connections are accessible by hand, located at the top of the cylinder running from left to right. Make sure all four connections are clipped in properly and the problem should stop.

Let me know if my instructions aren't clear and I'll send some pictures to show you what to do.

Getting some of this stumbling as well, and would like to check the coils. Does the radiator need to be removed to access them?
