I am close to your setup but with a PC pipe.
41.5 PWK carb
#7 slide
60 Pilot
185 Main
DGK Needle
1/2 turn out on the A/S on my bike with this setting.
Remember, If that stator isnt clocked right it will be hard to jet, what the right amount is? well that is the million dollar question!
Do lots of testing and if you cant get the ping out before it blubbers you are too far advanced. Clock the stator plate a bit Counter Clockwise to retard it a bit, and test again.
It took me a weekend or two of fiddling but i eventually got it right. Remember if you shaved the head or added compression that can play a factor in the ping as well.
