To be fair the NC30 and '35 just don't go wrong, abused or not, 100,000+ with no more than valve clearances done is not unheard of. All mine gets is oil, plugs and filter once a year, what else is there to do?
People who run them as roadbikes, trackbikes or even normalish spec (i.e sub 70bhp, just external mods) race bikes leave the engine alone. Only guy's chasing 80bhp actually take the bottom end to bits, even if mine did die I'd just get hold of another engine and replace the whole thing, wouldn't cost as much as a seizure either even if it did happen (which it won't).
I've never seen, heard, or even read on the 400 forum of an NC30/35 engine going wrong ever. Quite possibly Honda's finest hour.

I love my '28 but cannot in all sanity suggest to anyone they have an NSR as their only bike.
