The incarnates not only have Ashura and Indra's chakra but their own as well. You know, children inherit chakra from their parents. I'm sure Naruto's chakra was stated to be similar to Minato's.

Ignoring Edo Tensei psychic (which revives people with the power they had thorough life), Rinne Tensei revived Madara no longer had Ashura or Indra's chakra. That in my opinion is why his Rinnegan crumbled. He again regained Ashura and Indra's chakras by plugging the eyes into his sockets later.
