From all I gathered from the past few days of reading kart & bike forums, articles and sites for both the yz125 and cr125; is I should be in this ballpark:
Main: 170 – 180
Pilot: 40 – 45
Clip: 2nd or 3rd slot
Air screw: 1-1/2 to 2 turns out.
Like Matt said, fat on the pilot with the 60.
I’m throwing in a 170 and 45, 3rd clip, 1-1/2 turns out and see how that goes.
Like I said, the 160 and 60 was just a starting point seeing how that’s what the Keihin PWK 72 came with out the box.
