Carb probs

OK, today i was going to rejet my 250ex (k&n airfilter) I took out the needle but didnt put the dyno in, I reassembled and now when im in gear give it gas let go it takes its time going down 2 idle. Whats going on here?

sounds like its lean on the pilot id try to adjust the air screw before i changed any more jets. its searching for fuel why its idleing funny

Also the thing is that it still kinda moves in gear.
I have no pilot jets and it wasnt doing this b4.

you said you didnt but in dyno in what did you do to the needle

Nothing, every thing is set. it worked b4 correctly but then it started doing that. Ive taken it a prt like 5 times Put it back together and thats when it started.
