I'm thinking the throttle bodies may need setting up, you seem to have covered the other things I was going to suggest. The Oxygen sensor could possibly be at fault (?) if it's sending strange signals that would cause unstable idle and poor running of the engine. I'm not sure how you would diagnose this, possibly ohms reading with a voltmeter (?)

Bonne chance my friend, I hope you find the answer.  :821:

 johnmari, if it was my bike I would take it to the dealers and let them get it sorted out.
They have all the equipment  to do the job.

Best of luck. :821:

I'm such an idiot !  :112: :157:

I did the balancing of the throttle bodies and the problem was still there.
I decided, just in case, to check the sparks before taking the bike to the dealers and a spark was a little damaged ! The distance between the two electrodes was 0,1 millimeter...
I change the spark and everything's fine...
At least, i will have learn many things.

Problem solved. Thanks a lot for your suggestions.
