Sasuke being nerfed so Naruto can compete.

Naruto is in Rikudou Mode, so probably his Kurama got a big boost in its size.

i know that, however its still not the same size as the original or close for that matter


Look at naruto standing inside current Kurama's mouth opening

Now look at Madara stand ontop original kurama's head, He's not even the size of kurama's eye pupil

see the size difference? Kurama is still Split in half regardless of a Little size boost due to Rikudou mode, still nothing compared to the original

Hmm yes, I can see now. You got a valid point.

Naruto's Kurama is way shorter than the original one, meaning that Naruto is currently holding the Yin half given by Minato/Obito.

But, I wouldn't say that size is the only thing that matters. We can safely infere that Naruto's Kurama is only part of the whole Bijuu. The important thing is the motive of "why" does the size of Sasuke's Susano'o matches the size of Naruto's Kurama.

a) As you said in point 2, Sasuke's Susano'o is just shorter but has way more power than Madara's Susano'o

or

b) EMS has the ability to manipulate the size of Susano'o so it can be adapted to the context (it's way easier to use a Susano'o of the same size of their opponent to fight, as a guess).
