In the meantime I’ll going out in the garage and see what happens when I open the throttle gently. The video for that should be pretty small.

Yes it is clear, working as designed, thanks Popgun. The only thing is that while engine running a pulse train appears when opening the throttle that lowers the idle speed. This video is clue to understand what happens to my bike, specially at 0:35 very clear.

I would not expect the idle air control valve to have much effect once the throttlebody(ies) opens.
It sounds as though the fuel injectors are not compensating properly for the throttle bodies opening.
One possibility is an incorrect setting on the throttle position sensor...hence the TPS is not properly informing the ECM of the throttle position.
If that is the case, the first step would do a TPS reset procedure and if that has no effect, then follow the manual instructions for checking the voltage for TPS fully closed and fully opened.

Post 651: A, B & C
From post 617 in this thread
These are basic TPS checks condensed from FSM 5-23 and 5-24 (no Honda MCS diagnostic instrument needed):
DTC 8-1 TP (Throttle Position) sensor low voltage
With ignition switch on and stop/run on, probe sensor contacts to verify steady voltage increase from throttle fully closed to throttle fully open.
With ignition switch off, disconnect the connector, then with ignition switch on and stop/run on, measure voltage between connector pins black/yellow (+) to black/green (-) for 4.75 to 5.25 vdc.
If no voltage, with ignition off, check continuity on black/yellow to ECM connector, for continuity of center pin sensor output black/red wire to ECM connector and for no continuity (infinity) of black/red wire to ground.
DTC 8-2 TP (Throttle Position) sensor high voltage
With ignition switch off, disconnect the connector, measure sensor resistance between black/red and black green of 0.5 to 1.5 K ohms. Then with ignition switch on and stop/run on, measure voltage between connector pins black/yellow (+) to black/green (-) for 4.75 to 5.25 vdc.
