Bike won't idle and dies

So I just cleaned my carburetor on my yz450f 2006 and I also adjusted the needle clip down one position because it was running lean and after I put it back together it was running fine even better than before but today I started it up and it wouldn't idle and then it would backfire and then it stopped and it also seemed a bit louder than before so then I tryed to start it again and it wouldn't start unless I pumped the throttle 2 times then it just did the same thing

What I want to know is how can I fix this and what is wrong with this thing

It's also been really cold lately so could that be a factor?

fourstrokes get really sensitive in the cold, run it on choke a bit longer, or adjust the idle mixture screw.

I've tried that it won't even idle with choke on

might need to clean the carb again then, focusing on the idle circut.
