The bike is stock and no modifications were made to it. I always need the choke on to start the bike. It idles fine for about 20 seconds and then it dies. Do I need to adjust the Mixture screw on the carbs? What is the factory setting for a 2004 vforce 2.5 turns out? Or do I just need to adjust the idle?

Thanks in advance for any help.

 

1.5 TURNS OUT on air mixture screws,check air filter for dirt or bad spark plugs

 

adjust idle if warranted
