were u havin issues leaning out the pilot ? Im dropping pilot sizes trying to lean out the bottom end its rich af. Was running great in the fall but was still rich and now that its summer its rich af now i dropped from a 52 pilot down to a 45 and its still rich. Im getting closer i think. 

Im at 45/160 right now with clip on too of the CEL. Now midrage is ok, will try 158 today.

It look like lean needle, whats your needle setup?

I got it leaned out now with a 42 pilot. are you telling me I have a lean needle? that's def not the case, im at the 4th clip on a CEL needle.  middle was too lean, 4th clip worked fine.

Hey Op. I just saw this thread and saw you never updated with jetting. I am running the low ports on my bike with stock carbs, same elevation (close to it), vf2s, pods, slp pipes with 150 psi.

My jetting is perfect with 360 main, 37.5 pilot, vitos needle on the 4th and air screw is 1.25 turn out right now. once fall hits Ill up the main a size and go to 1 turn out just to be safe.

Claude, you might wanna try a cgl , it's the same diameter and taper but will give you more adjustment
