I dont know about other people but if you could explain in detail a little more of what your talking about it might help in diagnosing the problem.

So your saying that your RPMs dont really come into play at all its your speed only? Second gear and you hit 80mph, your bike takes off. 3rd gear it does the exact same thing at 80mph? The same for 6th gear? That doesnt make sense to me unless maybe something is stuck into your breather and its not getting good airflow till you reach a certain speed.
