[GG221]

Currently running 172, 42, NECJ clip #2 from top. This is what I run at about 5,000 feet and ~70 degrees F and it feels pretty good, maybe just slightly rich. I went for a ride at 1000 feet and ~32 F with the same jetting.
When I checking my pilot jet with the air screw before riding... I started at 1.5 out and turned the air screw in, as I was turning in the idle began to slow. I start turning back out to 1.5 and it is higher. I get to 1.75 out and it is racing fast. I keep going out 1/4 turn at a time and the racing fast idle does not change. From 1.75 all the way to 3 out it was the same very fast idle and did not change rpm. So I went back to 1.5 where it just barely slowed down and sounded a lot better.
I thought that this meant a rich pilot jet, is that correct?
I started to ride and the bike would bog for a second off idle, I turned the air screw in to 1 and the bog went away. Bike ran fine for most of the day. A few times while hill climbing with the throttle open it would bog and almost die, I would have to clutch and rev through it and the bog went away. This happened about 6 times in 6 hours. Here is a pic of the plug that I put in before the ride. My bike also seemed to be overheating easier than usual.
What do you think? Probably lean needle because of the open throttle bog? What about the pilot jet? I?m also confused because still seeing lots of spooge out of the pipe.
