Greetings everyone, and first of all happy travels and safe roads to all of you.
My first post here, and I'm looking for advice about the fueling problems. I will try to keep my drama-telling short, and hope that my story can be useful to some who encounter/ed similar issues. The bike is a 2012 model (world crosser) with 60-70k. Her main role is to take me far (2k-3k trips in Italy/Balkans/Greece), but I also take it sometimes to go to work (50-50 city/highway usage). On the highway, besides the non ideal wind protection (ok I'm tall, and put a Givi Airflow) it's a marvel of stability. In the city it's a totally different story, and here's where the fueling issues come to the surface.
Trying to smooth out throttle response (good throttle bodies cleaning included +KN) I installed the Arrow headers only (stock exhaust). The <2000rpm was better, and the >3000rpm response with a little more grunt, accompanied by a more aggressive sound (yet kind of "dry" to the ear, OK I know my mixtures are lean from the factory). In between (2000-3000rpm) it was still so and so, but I could live with that.
The Chaos started when early this year I decided to go one step further and unleash the full potential of this fantastic engine (little did I know...), added the Arrow exhaust as well to have a completely "open" system. The symptoms included (both S & T modes):
I'm not looking for the *magical answer*, and I know this type of issues have already been discussed before. If you could please direct me to some previous readings it would be a great help! ...and I thank you in advance for it.
(PS. Yesterday I put back the stock exhaust and the idle-dying things persists. I has to be related to the ECU adaptive learning (how to die) I suppose...
Seriously, please help!

- horrible decel pops (had to hold the clutch on almost every decel)
- unstable idle with hot engine (dancing between 1000 and 1200 rpm)
- when re-applying throttle after brakes (say, inside a turn) huge choking for 0.5 sec and then a nasty kick forward
- the surge around 2000 rpm (2nd/3rd gear, low city speeds) got worse
