^ Hmm... I believe Kakashi said something like "(Naruto) have 4 times more chakra than I have. And if you were use to Nine-Tails chakra, you would have 100 times more..."

Also, remember when Orochimaru used Five Elements Seal on Naruto? It affected on his chakra control and prevented him using Kurama's chakra and he still created great amount of clones against Rain ninja and healed pretty quickly after his fight against Kiba(even if he used Hinata's medical ointment).
