Hesitant on acceleration
SOURCE: fuel mixture screw
Begin by screwing the mixture screw in all the way until it stopps,,,but ONLY JUST STOPS,,,,,DONT FORCE IT,,,then look at the top of the screw slot,,and call that 12 oclock,,,now turn the screw out to you three full turns going through 12oclock,,that means 12 to 12 is one turn.
then start the bike,,,finish your adjustments now by slowley turning the screw outwards until the engine starts to misfire,,,at this point turn the screw back in one half to three quarters of a turn.Now you have the mixture set roughly.
For fine tuning,, you need to use a monometer while turning the mixture screw
Best of luck...
SOURCE: where is the air/fuel mixture scrue?
i'm not too familiar with dirtbikes but my experience with street bikes it has been on the underside of the carbs and if stock it is typically covered by a brass plug. this plug is just there to satisfy the epa you need to drill it out but be careful the screw is directly underneath the plug so as soon as you break thru pull back then use a screw to extract the plug. hope this is the answer you are looking for.

Hello,
Clean-out your carburettor...
Idle circuitry is faulty/obstructed.
SOURCE: i have a 2002 CR 125. Runs great but has black
The mixture screw is used to get the transition from idle to throttle up smooth, and not to bog.
Sounds like your jetting is to rich, or too big. Read your plug as it's probably black. Then go smaller on your pilot jet, run it and read it again. Make sure you run 32:1 mix, and jet the bike to match this.

the jetting should not be a problem, perhaps the air cleaner element is dirty or the element even if it looks ok sometimes needs a new one, the smaller motors often rely on the right intake vacumn through the filter for the carbs to work as designed
