Its a 1981 ch750K.

Ya, I have to use choke to get it started, otherwise it'll stall.
I usually start it up and have to pull the choke out manually as far as it will go. Then after it warms up a bit I give it a half turn so it will stay out. Then I put on my boots and helmet and by the time I'm done that its warm enough to ride.

At least it was until a few days ago when it started misfiring at around 4.5k rpm's until I rode it for 5-6 blocks, after which it would start riding fine.

Everyone here is all over the map guessing.

Did you use the choke to get it started?
How long did you leave the choke on?
You may have to leave the choke on for a couple blocks in cold weather.
Also you can use partial choke.

You said it ran fine after it was warmed up.
What year is  this CB750?
