Can Naruto create unlimited Rasenshurikens anytime in future? Naruto's Sage Technique is just a free form energy with which he manipulates the wind-natured chakra in Rasengan to create Rasenshuriken. However, it used to be the case that he only managed to create maximum of 2 Rasenshurikens by adding his wind chakra before his Sage Mode came to an end.

If he is granted unlimited chakra from Kyuubi, can he create unlimited number of Rasenshuriken?
No, I don't think so. I believe that Kyuubi's chakra isn't unlimited.


   First, Kyuubi cares, that Naruto wastes it's chakra. Second, Hachibi's fight against Sandaime Raikage suggests, that the chakra of a beast isn't unlimited, because Hachibi was knocked out because of exhaustion. Because the beasts are pure chakra, I think that would mean, that it has too less chakra.
