A lot of new bikes have a automatic choke ,but if you look at the carburetor you should see 2 cables 1 is the throttle cable the other is the return cable both run up to the throttle hand control (some bikes might not have a return cable) if you see a third cable its probably the choke cable so you will need to follow it , sometimes it might not be a cable but a leaver on the side of the carbi , some cables run just under the seat or to the left handle bar depends .

the fact that it idles with the choke on indicates that fuel mixture is the problem here remove the mixture screw completely check that the o ring seal is not damaged & that the end of the needle is not worn or bent if either of these conditions are obviouse replace the damaged or worn parts general rule of thumb with mixture adjustment is 1&1/2 to 2 turns out give it a try
