No, Kurama Mode is not the big avatar form, that's called Tailed Beast Mode. Kurama Mode is just the complete version of Nine-Tails Chakra Mode.

EDIT: I re-read that part, and you're right. Though I can't help but wonder, does he only need a little of their chakra to go into that mode? It's possible Sasuke was referring to the abilities that he needed the beasts chakra for (i.e. his Kekkei Genkai abilites), and Naruto's draining strength in general.

Naruto should have went back to all of them and borrow some more after the battle LOL
