turn your idle up some and disconnect one spark plug so you can adjust the other side. With it running on 1 cyl. turn the screw in until it runs rough then out until it runs rough counting turns then set it half way between the 2. Repeat for the other side. Number of turns will vary from bike to bike and even from 1 carb to the other so don't worry if 1 carb is 2 1/2 turns and the other is 2 3/4 turns more or less. If you are much over 3 turns increase your pilot jet 1 size and try again. Once all is done adjust your idle with both cyl. firing. There is a simple carb balancer you can make from clear tubing and a yard stick with 2 cycle oil in it, costs about $5 more or less to make.
