For all the people saying naruto without kurama..stfu. hes never been without 9 tails so saying he has butloads of chakra is opinion not fact
and just because he's uzumaki doesn't mean he automatically has 100xthe chakra of a normal shinobi.
So let me sum this up for you guys...
FACT:naruto has had kurama since near birth.he's never used purely his own chakra.
FACT:not all clan shinobi get a kekkei genkai(examples: kimimaru,hashirama,the uchiha)
FACT:the only time naruto has ever completely run out of chakra was in part 1,before he had any control of 9 tails
think about that
