Hi!

My klx250 EFI makes a strange "squeaking" sound that comes from the throttle body. It starts right after I turn on the ignition, does it for a few seconds, than a few seconds of silence, then repeats. It goes on as long as the ignition is on and the engine is not started. It's only been doing it recently, I don't remember anything happening that could cause this. I'm not sure it's connected to it, but an other symptom is that when bike is running, sometimes the revs won't drop back to idle, even when the engine is warm.
Do you have any idea what could be the cause of these?

Uploaded a video to help identify the sound:
