Honda 250 single.
I'm sure it would have been obvious from the condition of the cross hatching on the bore if it had not bedded in. I'd also think that Honda are quite consistent in their engine building process. They're pretty much known for it, it's safe to assume that they do not build engines with a 15% variation in clearances.
And, the factory process has been designed to break in an engine properly. In all the new vehicles I've had, not one has given any indication that the bed in process did not work.
But this is the same old story. The idea that people who've never designed an engine in their lives know more than the engineers who design engines that spin over 12k rpm, meet all current emission standards, have a 2 - 3 year warranty and are expected to last beyond 100,000 kms with just routine maintenance.
One of the biggest things I find annoying on the internet is the "ArE yOu An EnGiNeEr?!" Karens. It's a lazy way to shut down a conversation.
Do you know what mechanical engineering is? It's the science of recorded failures. We tried stuff, some of the stuff we built broke, and we kept notes. " Aw shit, that bridge fell....make a note for the next guy". Young kids pay good money to have access to those notes, and they get the title of Engineer in return. Spend a few years memorizing the hard knocks the old guys learned the hard way. Info sharing is great for society. Keeps things progressing vs constantly relearning.
You know who else has the same knowledge and understanding? Anyone interested and willing to educate themselves. Even if they didn't pay some school to brand them with a title.
Mr Honda didn't turn in his final college exam after completing it. The professor told him that he couldn't get his diploma if he didn't turn the exam in. Honda sent himself to school because he was horrible at metallurgy and his piston rings were garbage. After taking the exam, Honda recognized that he knew all the answers. "I came for knowledge, not a diploma. I have the knowledge I came to get".
If you saw the bullshit I have to fix because some engineer decided it was time to do things different, you'd maybe start having more respect for actual know-how vs dumping faith in bought titles.
