Nope he has been with Minato for 17 years in the SF fighting or doing whatever
These were Hiruzen's exact words when describing the Shiki Fujin, "Their souls will mingle, hating each other and battling the other for all eternity."
So apparently when Minato sealed Yin Kurama, he effectively condemned himself to fighting it endlessly for the rest of time. That would be a probable scenario for Minato to use his techniques for the bijuu to see.
That addresses Minato's fighting style itself but not the principals of senjutsu and how it's acquired. You activate SM by gathering the energy of the natural world around you and intermixing it with your two energies to create sage chakra.
The issue now is whether or not natural energy would exist for Minato to use where he and Kurama were battling. Considering that the shinigami is depicted as an ethereal being with supernatural features and that Edo Tensei, a technique which functions by extracting the intended soul from the afterlife to return it to Earth, failed to restore him, I think it's safe to argue that Minato's soul resided beyond the conventional realms of existence.
Natural energy, by its definition and namesake, is an unseeable force that exists all across nature (Earth's nature). Given the unique conditions of Minato's captivity in the stomach of a supernatural being (one which probably exists in a realm beyond time and space), how likely is it that Minato would have the tools necessary to use Sage Mode and demonstrate it to Kurama? Personally, I think it's unlikely that he was able to use it then. The shinigami is an entity that probably falls under the same category as Susanoo's gourd.
not to mention that once he was also sealed in his wife so to think that he's not aware of his abilities i think is totally wrong,
Given all the information about Minato's battle tactics and how he operates in a fight, is it consistent for him to resort to SM? Or for Kushina to pay much heed to an ability that exists separately from the technical skills that Minato amalgamates with his wife's?
also if the Yang Kurama in Naruto could tell that Naruto surpassed Minato and Kushina that means he's pretty much aware of his abilities and what he's capable of and this was the Kurama that has never been with Minato but within his wife so if Yang Kurama knew this i don't see any reason why Yin wouldn't .
This was brought up in a previous discussion that we had and my answer to it remains the same
"Kurama admitted to himself that Naruto had surpassed them in terms of the amount of chakra that he could link and transfer to others."
Kurama is aware of the abilities that would entail his involvement. Chakra transference. I don't think he's ever offered much insight into their other abilities that weren't involved with him. Surpassing, in the way he described it, was in a strictly limited context which wouldn't support the notion that he's aware of everything they have.
Also nothing was stopping Minato to ask the Yin Kurama if he can do BSM after he saw Naruto doing it or for Yin Kurama to tell Minato about it if Minato was indeed able to do this,
There was little time for Minato to coordinate any chakra arrangements since they had both started fighting almost immediately after Naruto discovered that he could use both modes simultaneously. It goes from them using the Rasengan against Obito to some brief (very brief) conversation, Naruto trying to create a Bijudama forged with natural energy, and then Obito proceeding to release the Shinju which rendered their original attack strategy useless. All in the span of nine pages.
Furthermore, Minato wouldn't have any need to use BSM since Naruto already offered to supply the necessary sage chakra to the Rasengan.
plus there was never shown to be a lack or trouble in their communication as you claim this to be the case on the contrary there communication was rather fine,
Really? Was Minato even aware of Kurama's existence in his mind before he revealed himself (he acted surprised when he noticed that Kurama was looming over him from behind)? Was the chakra he was using received consensually or did Minato steal it from him at some point when they were battling inside of the shinigami?
Neither of them have had the interactions that Naruto has had which include the great majority of his life. That includes his training experiences which Kurama obviously wasn't a witness to during Minato's time since he was confined to another person's body (unless Kushina decided to tag along as a spectator at Myobokuzan).
this Kurama even cheered Minato up when he was feeling low about himself he was very nice to him on the other hand
Morale is a critical element to an effective soldier's performance when fighting. Minato acting like a dejected failure would have been counter-productive to what they were trying to accomplish.
I won't deny that there was genuine compassion on his part, but to argue that it's of the same long-term intimacy as Naruto's relationship with his Kurama? That it would influence Kurama's information about Minato? No. Especially when they just came out from an imprisonment that had them locking horns with each other resentfully for 17 years nonstop. There was combat and technical experience, but on a personal level that pertained to Minato's own life? Not really, excluding whatever time Kushina spent with him.
the Yang Kurama within Naruto wasn't like that with Naruto actually Naruto had it harder in this department than Minato,
Naruto also didn't have the proper environment that would have compelled Yang Kurama to cooperate with him like Yin Kurama did by being thrown out to fight against the Jubi immediately after being freed. Remember that the original motivation for Yang Kurama's assistance was self-preservation. This entire war could be looked at as the catalyst for Naruto's newly formed relationship with Kurama.
Before that, Naruto never really paid much heed to Kurama's well-being (excluding an apology he made for forcibly removing his chakra after his mind had been "cleansed" of the negativity afflicting it).
I'm not sure when Yin Kurama assumed this docile persona around Minato but he seems to take special consideration of the conditions surrounding Naruto's relationship with his Yang counterpart.
and if the bijuu's have anything relevant to say they would they won't hold back as it was shown many times so i think this lack of communication doesn't have base at all for why Minato isn't able to go BSM instead it has with Minato not being able to do it if he could Kishi would have showed that just like he did with Minato being able to go KCM and BM .
The bijuu haven't exactly been on good speaking terms with humans since Hagoromo's passing. Animosity had apparently developed between them and for that, the bijuu's opinion of them turned to murderous hatred. Being forcibly contained inside a person and expected to act as a tool lacking in sentience doesn't lend itself well to cooperation or wanting to even speak with them (besides voicing their dislike for their captors like in Shukaku's situation when he was conversing with a young Gaara).
Hell, besides the Sand Priest, Killer Bee is perhaps the first human to ever treat the bijuu as an equal rather than an implement of someone's war machine or a monster.
