iridium plug raised my idle, how lower?

Hello, I would like to keep the iridium plug in my efi scooter - but installing it raised my idle slightly....with also some loss of engine braking when throttle is rolled off. Can this be reset, or should I just remove and go back to stock NGK plug? There does not seem to be a simple idle adjust screw ---- adjusting the idle stop screw out 1/2 turn had no affect....
Really don't want to fool with the efi settings.
Thanks for your thoughts....

Is this for the Kymco?

Try unplugging your battery and reconnecting it. This may reset the ECU which could auto-adjust the idle. There may be another way to reset it for this model, but that's how it works for some other injected scooters.

Another possible way to reset the ECU is to cycle the key from the "off" position to the "on" position (don't hit the start button) in three second cycles three times.

Key "off" to "on" - wait 3 seconds

Key "on" to "off" - wait 3 seconds

Repeat two more times.

After the third cycle, start the scooter and see if the idle is reset.
