We've seen that a tiny amount of chakra can be re-ignited into a full-blown chakra cloak. We've seen that Gaara was still able to extract Shukaku despite not being his jinchuriki for months.

We've seen that Naruto could enter a Biju's mental plane simply by being in their body and that they could communicate short distances telepathically without shared chakra or any contact. Furthermore, we've seen that Naruto could enter a shared mental plane merely by touching them at the same time. Whatever chakra they gave Naruto wasn't big enough for him to use. It only became useable after hagoromo restored these pieces of chakra into biju. But before this, the Juubi sensed the chakra inside him and reacted strongly to it, and it was enough to pull out biju (again: despite Gaara not being a jinchuriki he nevertheless could pull out Shukaku -it needn't be a lot of chakra)

All this suggests that to manifest some connection, only a very small portion of chakra is needed.

Now to clarify, because i can already imagine the comments, if the Biju so desire they could (Presumably within some given range - large but not infinite) transfer chakra to Naruto and so restore his pseudo-juubi mode. But doing this would go completely against everything the Fourth War was about (for the biju), namely that they aren't pets to be called upon every time someone is in trouble. They parted ways and went on to do their own thing.
