Unfortunately it was not neutral indicator, bike turned off one day and didn't start anymore. Given him into a Yamaha service, and guy contacted, ignition coil failed (faulty). After changing it, no more pops from exhausts(Akrapovic) , low very very low surging, no cutting out in 350 km, and bike is going like hell
I have checked diagnostic and have seen that TPS is now set at 16 (before was on 19) and CO is on 20 (before 11) Next is DNA stage 1 and 2, and O2 eliminator.
