Jerky engine

My Hyosung gt250 out of the blue started to act up.. The rpms are erratic and the bike/engine follows this by jerking/jolting. Best was I could explain would be when a car is out of fuel and it struggles resulting in a jolting feeling.. Like that but a bit stronger.. It does this while on a full tank both at idle and when going... 

Help??
