Will not start! HELP!!!!!

Okay I changed out my front sprocket, and went to test it out, But I can't get the bike to crank. What could be wrong. BTW I rode it 2 weeks ago and everything was fine.

Any help will be appreciated.

You cant get it to crank or to start? If it wont turn over, check your battery first.

The battery is fine I can get it to run with the choke for like a min or 2 then after i take off the choke it dies.

Thanks,

Your out of gas almost, your airfilter is covered in mud or dirt, you've got mud in the bottom of your carb, or your plug is shot..
