Is there any jutsu that Naruto won't be able to master without the Kyuubi? I'm just curious if there is any jutsu that would be impossible for Naruto to learn or master without the powers of the Kyuubi inside him?  

If there is, which is it and why won't he be able to learn/master it without the Kyuubi? If there's none, then I guess Naruto is actually a smart ninja.
Well, here are some of the jutsu Naruto probably can't (or will be near impossible) to learn without Kurama:


Techniques from elements other than Wind - Naruto's natural chakra affinity is towards wind, while he can train in other elements, he probably won't be able to learn some of the other elements. (Actually has nothing to do with the Bijuu, that's kinda what happens to everyone)
The Bijuu Dama - a Bijuu specific technique (the nuclear-warhead like black sphere).
It's possible that using Kurama's Yang element chakra (sealed within Naruto), he'll be able to do something.
Tajuu Kage Bunshin - Even though Naruto naturally has massive chakra reserves, he wouldn't be able to make as much copies without the Kyuubi Chakra Pool.
