Definately hard to know what you're talking about w/o seeing a pic... but I'm pretty sure that you are looking at the semi-rough texture of the counterweights. Should be ok...the counterweights aren't machined so they are still roughly forged and should have a slight texture to them.
I'll post a picture in a bit.
