1) your idle is low. With the bike on the centerstand, sstart and warm it 5 mins so it isn't running on "enrichment mode" or warm-up. Then turn idle screw (screw on throttle of carb) clockwise to the highest possible rpm without spinning rear wheel ( usually 1800 to 2000rpm)
2) clean your air filter
