Remember that the Kage Bunshin is a forbidden jutsu for the amount of chakra it uses. Naruto can use it as much as he does because of his high amounts of chakra, but that doesn't mean that he has unlimited supplies of it.
The one to make the clones is Naruto, with his own chakra. As adonai pointed out, Kyuubi's chakra seems to destroy the bunshins. At least from 1 tail onwards.
