looks cool ehh?

was there a temperature change when you noticed it first?

usually a half turn out on the a/f screw will take it right away.

its going to do it no matter what if you let it idle for a period of time.. these bikes arent meant to idle

CR250 R motorhead is right, never let a 4 stroke sit and idle for any amount of time. I had a WR and mine did that and it was a little lean. A few adjustments and it was fine.

oh really, I wasn't aware of that. So I shouldn't let the motor idle and warm up after first starting it?
