A lean bike can still pull clean up top. Please do a plug chop to make sure you arent lean. You always wanna start rich and work your way down.
I've got 30 oko's as well. Mine bogged bad off idle as well with 48 pilots REAL bad. It was a bitch to take off. I had to go down 3 sizes. I was getting too much fuel. You can pull the choke out and rev it a bit while IDLING to see if it wants more fuel or not. If it's better with the choke a little or fully out, the pilot isnt big enough. If worse, it's too much pilot. You can figure the pilot/air screw out while the bike is in neutral. You want it to rev very clean like a 125 dirtbike as my builder would say.
The needle clip position doesnt come into play till about 1/4 throttle, correct me if im wrong. Put your needle back like it was and leave it alone till your off idle issues are solved. Well you can leave the needle clip as is and mess with it later. It's not gonna affect your engine right off idle.
