Hi my 99 rm 125 looks to have the air screw turned out signifigantly. The air screw is the bigger, black screw right? Anyhow How many turns are reccomended? Also if I tinker with that will i have to adjust my idle speed screw?
depends on whats been done with the jetting. the air screw controls the pilot system. if the pilot jet is stock i believe the setting is 1.5 turns out from lightly seated.
