use to be called blueprinting....
those casting dags etc weren't on the blueprints
"CAD files these days" but happen in the casting process
so removing them is bringing the motor closer to what the
blueprints "Cad files say it should be...

So remove them.. theres nothing to lose....
I polished my TTR250 head to near mirror finish...
took 3 days with a mico die grinder...
