fuel mixture screw

  1. ktm 250sxf 07 carb setting

    Off-Road / Enduro
    on my 07 250sxf im having trouble with the idle, when you rev the bike, the revs come down to about choke level then stay there for around ten seconds, then come down to idle again, i wanted to sort out the fuel mixture screw setting, but i dont know how many turns out and which way?? anyone?
