Yes sir, I make 1/8th turn changes and check the transition and top rpm after every other change. When you get close, one of the changes will make more difference than the previous ones.
PS, don't forget to keep lowering the throttle as the idle improves.
Hobbsy, thanks for the help on the Saito 50. As you suggested, I leaned the HSN to peak and then began to lean the LSN for best idle. I got nearly one full turn more on the LS than I had before, and now I can maintain a safe idle of 2000. The rich running in mid range is significantly reduced. It still sounds a bit rich in mid range, but no visible smoke.
