Naruto had half, just like how kin and gin both had kurama too? Why else would they be Edo tenseid still with the chakra just as Minato did? And the totsuka part is in the databook. I provided enough evidence which is all backed up by the manga to prove Naruto always had full powered kurama.
Also if he didn't, then why when he got both halves he wasn't stronger? He had the same BM.
I need a scan mate, when did Totsuka fail to pierce a jin
And Kin and Gin had a small part of kyubi chakra which they were able to gather after the 9tails attack on Konoha. They sealed that part inside themselves hence they were resurrected with it.
They did not have kurama since half was in Minato and the other in Naruto
Sorry for double post
EDIT: ignore the shit in red, mixed up some filler character with Kin and Gin.
"heir attempt to capture the Nine-Tailed Fox for their village. They were instead swallowed whole by the beast. The brothers survived inside Kurama for two weeks by eating the beast's flesh; this would eventually lead to the fox regurgitating them. This left them with unusually large chakra-reserves and abilities similar to those of a jinchūriki"
So yeah they did not have Kurama
