That's just how mechanical parts are - all parts are slightly different.
I've used a differential between the two motors, and then measured the
position difference with a rotation sensor. In NQC I just make one of the
two motors "float" when the difference gets to big. In this way the
robots moves straight with two motors. When I want to turn, I stop the
regulator task first, and starts it afterwards - just remember to reset
the rotation sensor counter.
