let involve common sense into it. Kakashi says naruto's own chakra is 4x his own, meaning naruto's chakra is 4x larger than that of kakashi.
Kakashi now later said if the kyuubi[B/ ] is not suppressed meaning if the kyuubi's chakra is allowed to mix w/ naruto's chakra he will have 100x that of kakashi.
Nooooo he said that if he did not have to use HIS OWN chakra to surpress it, his Own chakra would be 100x greater look it up dude
