RE: Welcome to Club SAITO !
Low Speed needle still too rich, peak the HS needle and then turn the LS needle CW 1/8th turn at a time checking the transition and HS performance after every other change. When you get the best idle you'll be a little too lean for a good transition, richen it CCW 1/8 turn and re-check the transition, now richen the HS needle for safe running, I use 200 rpm for engine health.
