Thanks, that was very helpful. Yesterday I hit the worst possible conditions, it was 10 degrees colder then normal, the air was really dry instead of the usual high humidity, and I was riding a little lower then normal. A turn in on the air screw made it decent but still was running lean. If I want the bike to survive a day like this I'll need to leave it as it is now, just a tad rich for my normal rides. I guess I have the right margin of error now.
Currently at 45 pilot, 2 - 2.5 turns out, 1 step leaner needle on 1st position, 178 main. Runs good on my normal riding conidtions. The slight pinging is only when I really load it in 3rd or a higher gear on a hill so I guess I will live with it.
