Idle Problems

Hi
I have a Forza 125 from 2015 with 10.500 miles.
Since a few days it idles somewhat uneven between 1200 and 1900 RPM, used to be 1900RPM.
It does start alright, however the response is very sluggish if I start driving with slow speed. There seems to be sort off delay till it gets going.
Any Ideas?
Thanks
