When lean, your bike will be in asmhatic, breathe hard, won't pick up speed easily, run hot, may backfire.
1mm on needle will make a difference for sure. If it is better now than before, keep on going untill it gets worse. Then you will know where perfect (for that day! ) is.
Have you set the fuel screw? This is what will tell you if you need to change pilot jet or not...........

I run 90 octane unleaded, its the highest I can get. I do not have the fuel screw (yet). I dont get backfire on decel but I do hear a flapping sound that I thought might be the AIS. I have got an occassional backfire when I shut it down. I have a temp gun that I could check my head temp with if I knew what normal temps should be. According to the jetting DB it looks like I should try a 170 main if this needle adjustment isnt enough, is 168 stock?
So it really kind of sounds like I may be chasing a problem that doesnt exist. The bike runs great I only though it was lean because of the white plug reading. I just want to do everything I can to keep from damaging this bike. I hope to ride it for a long time.

I think the #48 pilot will work best if you have done the airbox mods and deristicted the pipe.
The adjustable screw will help you - a must do...
The needle really needs to be adjustable. I got one with my bike. Some come in the AIS kit or you can go JD as I did, RED works best in warmer conditions.
At the moment your shims should be OK.
OEM is unadjustable and the needle position is the same as clip in the middle or #4 position - I just checked.
I measured it and the distance between #1 and #7 clip position is 5.5mm - i.e. 6 alternate positions = for 5.5mm. That is close to 1mm per clip so your 1mm shim is the same as needle with clip #5 position (from the top)- so when you get your adjustable needle you know where to start....
