The idle screw is the one on the throttle. The mixture screw is the one on the side of the carb. Seat ( DO NOT TIGHTEN) the mixture screw, and turn it OUT 2 1/2 turns. Adjust idle screw so bike is not stalling out. Ride/run for 10 minutes. Place bike on center stand. Adust mixture screw in 1/8 turn out incriments, waiting 20sec between turns, until rpms increase until they will increase no more. This is max/lean. Turn screw IN 1/4 TURN, this is Final Mixture. Adjust idle screw to as fast as possible without spinning rear wheel, this should be 1800-2000 rpms.
