yz 400 carb question

ok i posted on here about a month ago about my bike not starting and i was told to clean out the carb. did all that and cleaned out the air filter and checked plug. it'll run now but not very good. back fires alot if it gets worm but usually dies once i give it any throttle. thanx for any help you all can give me.

make sure if you had the slide out of the carb to insure the plate is installed correctly......upside down it really makes one run funny

Sounds like a carb issue. Are you sure you cleaned all of it?
