Overfueling condition can be directly attributed to poor setup/jetting decisions (more fuel is better....everywhere....(NOT)

I divert, anyway you need to isolate the offending circuit and @jkv45 is on the money...pilot screw adjustment is a required, standard tuning procedure.

I'd advise to adjust the pilot screws first...progress from there.

Syncing with an accurate, precise pro manometer too.
Everything is stock except,

shimming needles, snorkel delete, kn air filter and kleen air system delete.
It’s so cold out so I’m not able to test the bike fully..but starting it does require choke (which is a good sign I guess) and it revs smoothly all the way up and immediately returns to idle 1,100 rpm when cold...hopefully tomorrow I will get to ride and see if there are any hiccups.. any thing I should look out for? Thanks everyone for their help once again!
