Because it is rubber bonded to steel which is the feature that makes it a balancer, I don't think that any other balance is necessary. Be sure that the end of the crank is perfect and remember that those two dowel pins are not 180 degrees apart. One side is a little closer then the other and if you check the Forum under that subject you will find a number who of people found that out the hard way.
