Naruto is only limited by how much chakra he has in his body. He has a lot of chakra. So one doesn’t know how many he can actually make. Also…it wasn’t the chakra of temiju. It was the ninetail fox’s chakra. Temiju was only manipulating the chakra for Naruto.
Naruto without using the foxes power is limited to 6 rasengans. Naruto didnt really need to use temjiu’s chakara. That chakara he used was from the fox. All of the tailed beasts jinkurin have unlimited chakara.
