the air fuel mixture should not have moved but if your carbs are n ot supported it is possible i guess. Under the front of the carb (facing the front of the bike) there scews about half way down the float bowl, you can't see them directly but you will see the opening (hopefuly you have the caps off of them) they are bras and are D shaped. You will need a D shape wrench or a very very small set of needle nose pliers to get in there. Best to set them both up the same. Turn the screw all the way in counting how many times you turn in (so you know where they were at) do this to both, then turn them both out equally to match the one that was turned out the most (if differrent) then once there, turn them out 1/4 turn each. Take it for a ride and see how she goes.
