i just got an 02 raptor 660. didnt run when i got but put new one way starter clutch and complete cleaned and rebuilt carbs. use small wire,carb cleaner and compressed air to make sure they were completly cleaned. has 160L/165R mains, 25 pilots k&n air filter with pro designs adapter and no air box lid and a gytr slip on and i was told all baffles have been removed from pipe. my problem is the bike will start and run fine if the choke is around half on but as soon as i turn it off it dies. bike runs strong when it runs just wont run with choke off. mixter screwer screws are at 3 turns each. do i just need to readjust these or am i missing something else. thanks for any and all help in this matter
