Are these scratches normal? 14Yz450f

Took my flywheel off this afternoon and found these scratches inside the case? Is this normal, anyone have these? If not what would this be from, bike only has roughly 40 hours. Bike is a 2014 yz450fImageUploadedByThumper Talk1450311735.898962.jpgImageUploadedByThumper Talk1450311766.286001.jpg

Looks like casting clean up from when the cases come out from casting and clean the slag off. It's Normal

That's normal de-burring. Nothing to worry about.
