IMO , yes. On the left side of the carb you see the "choke " know , down below that is another knob with a philips head on it. With the bike warmed up / idling rotate that know counter clockwise.....it's tunable with your thumb and finger. Do not have your hand on the throttle while doing this. You should hear the RPM'S drop during rotation. If they didn't screw something else up , this should take care of the issue....I hope.
