cutting out???

[daz|n00by]

hi guys aprillia 125 tureg model but rotax 123 engine (same as rs early rs i belive) ok the problem is this since the drop in temprature around my way both mine and my sons bikes have started cutting out at tick over even when warm, they tick over fine on choke until they start warming up then they tick over ok for just a short while after choke is off then they juust keep cutting out at tick over i,m wondering if this is a symptom of cold weather and nothing to worry about or should i adjuust the idle speed ? i dont mind adjusting the idle but could some body put me on the right screw to adjust please i dont want to mess the mix up as far as i can see the carbs look standard
thanks for any ideas in advance

you may be having the same problem as me with jets and ect ect, if the engine is smaller or bigger cc it might want a new jet or tuneing. The carbs are from your aprilia or are they from the rotax engine.
