Well if we look at the amount of chakra he used from each bijuu we can figure out that he still has some of bijuu chakras left. Before using the tailed beast rasenshuriken, naruto used the 4 tails' chakra for the lava style rasenshuriken, then he used shukaku's chakra for a smaller jutsu in the magnet release rasengan, then he used the 5 tails' chakra for Boil release unrivaled strength.

Now up till this point, he hasn't touched the 2,3,6,7 or 8 tails' chakras so he has more of those chakras than the chakras from the 4,1 and 5 tails. Then he uses the tailed beast rasenshuriken that utilizes all the bijuu. Now, we know he didn't pour all his tailed beast chakra into the tailed beast rasenshuriken because during his fight with sasuke, after sasuke took the bijuu chakra, he taunted naruto saying naruto only had a little bit of the tailed beasts chakra. We also know that it is needed to undo the infinite tsukuyomi. Therefore, since naruto didn't expend the chakra equally, he should still have a piece of the 2,3,6,7 and 8 tails' chakras and the rest is arguable since he used more of those chakras.
