SOURCE: Yamaha TTR 250, Idling Problem
check the inlet manifold rubber has not seperated from the aluminium part of the manifold ,this is very common on the ttr 250 and will cause the exact problem you have,if it is seperated either replace it or repair it with some good quality rtv sealant avoid sillicone sealant as it is not petrol resistant and will turn to jelly.adam

SOURCE: Cleaning Carb Jets
not to a trained ear also go by rpm and spark plug color
NOTE: use copper wire to clean jets, sync is just thottles are same position as all carb's just leave them adjustments alone will be fine if are out use a 1/8 drill an place in between piston/butterfly to carb bore to sync/calibrate
better use a manometer for adjusting screws
depends on condition of org parts
worn = richer running
new = lean an clean
also if changed the exhaust system need to
re-calibrate carbs for max performance

Time for carb cleaning, blow the jets with compressed air and check the fuel level in the float chamber, adjust if necessary.
Tht factory plug is where the air-mixture screw is and tht plug has been kept there for non tampering!
That screw is factory set.
Basically its the primary jet which is a problem in your bike's carb, but all in all might as well blow both of them.
Hope this helps!

First of all, assuming that the float level is correctly set, while running the engine at idle, turn the idle adjust screw in until it starts to get rough(pay close attention). Then back the screw out 1/8- 1/4 turn. If the screw has been removed, always start by tightening the screw all the way in and then back it out 2 1/2 turns.
