Mine did this when I got it. It took a while to figure out what was causing it, but finally got it. The outer wall metal guide on the right orbit was a bit warped. There was a wave in it which sent the ball toward the center drain. The wave was in the middle of the right metal orbit wall. Here is the kicker: to make the ball deflect less left, you have to bend the metal orbit guide exit MORE to the left. Because of the way it is attached to the playfield by bending the end of the guide to the left, it pulls the middle of the guide to the right and trues up the path. Insert a slotted screwdriver between the end of the metal guide and the metal post (near the hat, has a rubber post sleeve) and pry the metal guide exit to the left. You'll see the center wall of the guide flex to the right. I know it's hard to explain but give it a try.
