Pleassse everyone here is making judgement positive or negative based on very little information.
That's the very problem. You dont need to, or must not, force you to make judgement, either optimistic or pessimistic, from very little information. Just give good margin to it and make technical induction and deduction out of it that's still possible is fun and productive, but you just want to reach definitive conclusion and be given easy 1 or 0 answer because "hanging in mid-air" feels insecure and you cant stand it, and want to give verdict because it feels good. That's human propensity and weakness.
Of course MGU-H is breaking and PU is not good because Honda is poor or immature or whatever. But outright claiming like "broke -> poor design, how come knock-on etc" is superficial and childish way of looking at things, also lacking basic prudence, intelligence and respect, I'm afraid. I am intrigued by what they are doing and what difficulties they are facing and would like to know technical details as much as possible and want to enjoy and appreciate their technical journey and progress/development, not interested in giving "feel-good verdict", and I'm sure I'm not the only one, but at the same time I know I probably belong to the minority unfortunately.
Failure management or shel model or whatever those analysis are common engineering language. What makes difference is data/knowledge and empirical accumulation, they are still short of full 5 years while others have been doing for 9 or 10 years, plus they are catching up so have to be risky and aggressive rather than incremental/parametric approach, so in double or triple binds. Also this is a sport. There is nothing "challenging" about 125k rpm and 60 or 70cm shaft and securing resistance itself. What's challenging is making it relevant as a sporting application. That's the condition and context. And you dont really need to "feel" it's MGU-H. Honda said it's MGU-H altho the cause is still undisclosed, could be the same as last year (oil/water from compressor damaging bearing) or entirely different (like shaft oscillation, slimmed down shaft bit too fragile, etc). As I wrote above, give margin and dont jump to conclusion.
Regarding the fix they are bringing to Bahrain, it's nothing more than a temp patch of course, that you can deduce from other known facts like logistics (time it takes to send PU from Melbourne to Sakura, then deadline for shipping to Sakir) and physical limitations (time it takes to analyze, making judgement on whether break seal to dismantle PU or not, then analyze and find cause, and design and manufacture whatever modifications). Also looks like some are guessing they'd had new MGU-H in pipeline already or shud use STR as R&d but you can rule it out because Tanabe, Yamamoto and Asaki and previously Hasegawa have all been saying they prioritized reliability to establish secure R&D baseline, without which there can't be R&d in the first place, and such thing as new components at 2nd race is not ideal, or there cannot be anything worse than that, just too obvious. As Tanabe alluded in Melbourne, this MGU-H issue is nothing but huge blow and crisis for Honda. But I'm intrigued, as I wrote above. Hopefully they disclose some more info and will overcome it sooner.
