Idle screw question

While trying to start my yz426 this winter , I adjusted the idle screw to try to get it started and now its way out of wack. How do you get it back close to stock settings? I couldn't get the bike started then and still can't now.

Check the User Jetting sticky for the '02 model. There's a post in each section that lists the OEM base jetting, including pilot screw settings.

Should be between 1.75-2.25 turns or thereabouts.
