You may have a voltage problem, get a factory service manual and look for the numbers and check your bike.

all fuses are ok, the regulator rectifier is new, could a mass problem be possible?

New cheap parts from ebay, or good O.E.M. parts?
A rubbed wire?

Hello sososam
Yamaha does not sell that part separately.
Did you buy a Suzuki part?
Does it have six wires?
Do you have 12 volts at the red/white wire
Did install it so it does not bind?

test at the moment; ignition on: red / white wire = 12v, it's a 6-pin
before the original part broke down I noticed that it was heating .. same for the new ..

The ignition fuse did not blow?

Being stuck in the open may over heat the valve.
Is the hose connected properly?
Is the hose pinched?
The pintle could be sticking.
Did you clean the port well before installing the new valve?

Other than the supply voltage all signals to open and close the valve come from the ECU.
I don't know what the voltages are for those wires. I believe 12.
It would take some research to find the values for those wires.

orifice clean well.
I tried to start it without mounting the valve so open orifice, a start shot (without actually starting it I specify) and in the said orifies I saw a beautiful spark on the bottom hole .. is this normal?

today I have to start again to follow all the electric harness; visually nothing to report
i am really lost
The info of a computer cannot transmit a juice.
The info can give an order to leave the actuator permanently ON: therefore heating and grilling would this be a track?

No the beautiful spark is not normal.
Have you adjusted the intake valves? If not you should.

I have been doing some research.
I will add more information later today.
Going to the cafe now for some coffee.

the piston as well as the intake and exhaust valves were changed 1000 km ago I think it had to be done at the same time
bon café;)

Yes the coffee was good this morning.

The hose is the one to the air pressure sensor. If it is kinked or disconnect or broken it could cause a problem with the IAC.

It appears that the voltage to the other four wires should be 5 volts.
With the IAC connected to the wires does it cycle in and out when you turn on the key?

I would adjust the valves again. there should be no beautiful spark.

Do you have a service manual in you native language?

with the ignition on, the valve remains fixed. after start / stop, it seems to want to move. for the spark, the lower hole is a small duct which enters the combustion chamber just above the injection head; under the butterfly shutter

test: I start the engine by holding the valve (and not by screwing it as at the origin) the engine turns a moment then stalls; I remove the valve from its housing then cut the ignition: the valve seems ok because it moves (back and forth) but I still have my error code 37
