Anyway about naruto's chakra, we do know that he has a huge amount of chakra even without the nine tails, kakashi said it while trhy were training tree climbing and his stamina has been mentioned various times. Also, his chakra and the red chakra are separeted, that's why jiraya had him exaust himself before trying to use summon jutsu, so that he would be forced to use the red chakra.
