Idle air flow / Idle dropping down when under Power load

Hi everyone

I am looking to find out idle air flow ratio in injected version of Zongshen Rx3 2015 model.
I think the throttle body on my bike is made by Continental as written on stepper motor valve.

Over the years I was trying to establish good idle speed (with out good result) and turned the adjusting trotle screw in every location.
I want to start with good air flow ratio and see if this will help.

If the idle speed is to small the engine shut off if idle speed is to high it will trigger the red ( engine symbol ) light at dash board.

At this moment the idle speed on my motorbike is in good range till the cooling fans switch on.

When cooling fans gets switch On the idle speed is slowly dropping down till engine shut off.

When I use hited grips the idle speed is also dropping down and engine shut off

If cooling fans or hited grips get switch off before engine shut off, idle speed will return to normal.

I am not sure if this problem is to do with air/ petrol ratio or this problem is do to some electric faults.

Is the any sensor wich I should change?

Recently I have made upgrade to alternator on my bike from originall one 200W to Zongshen 300W and new regulator.

Valves has been set recently with full service change
- air filter
- fuel filter
- Oil filter
- oil
- new Map sensor
- spark plug
- yuasa battery one year old charge up regular

On old alternator it was the same problem.

Any suggestions as this is very annoying problem

Thanks
