covers ant the 750 has 6 bolt holes in the same shaped covers.

my bike has same style head i was looking at getting some threads in there but the pipes are nice and snug the way they are mounted so ill leave them for now glad to see its not just my bike someone told me it should have them and someone had cut them out because maybe theyd stuffed the threads....
