You don't just give the bars a brief nudge to the right and expect the bike to lean to the right and keep turning to the right all by itself - my motorcyle never did that. You keep pushing on the right side of the bars until you want the bike to straighten up and quit turning.
You can push all you like but the fact is that once you are in a turn of a fixed radius your front wheel will be turned toward the turn. If you're turning right the front wheel will be turned to the right. No question you need to apply some force but that is not the same as countersteering as the steering angle is in the same direction as the turn. Read the wiki page (and associated references) I quoted earlier. It explains everything quite clearly.
