That's wrong. Seat the mixture screw and turn it out 2 and 1/2 turns, do not worry about idle, if the bike stalls with the mixture screw set to that, turn up the idle screw till it stays running.
Then turn the mixture screw out another 1/4 turn and see if the RPMs increase. If they do, repeat until the RPMS no longer increase. Once you have found the MAXIMUM RPM, turn the mixture screw IN 1/2 turns and LEAVE IT. This should be a slightly rich mixture, which should be ideal.
Then set your idle between 1600 and 1800 RPMS.
