Wow! Are you trying to launch the pistons through the cylinder walls ! I would never rev up a brand new unbroken in engine in such a way. Other than that, a nice job on the rebuild.
Checked out some myth or not video about breaking in an engine, they took 2 engines reved one like crazy and gently broke the other in. Tore them down and sent out some oil samples to check levels of different metals both were exactly the same. As long as it wasn’t run dry with no oil or no assembly lube it’d be fine.
@@jonathanbrown1120 Well . It's still very good idea to break engine in , mainly because of ring and their fitting ,but i somehow agree with your theory , main thing that you don't want to happen is overheating the engine . That can cause serious damage , especially if there are new pistons
I’ve always been part of the “run it how it’s gonna be run” when breaking in, of course I work my way to it. Still would make me nervous redlining one on start up
Think about once an engine is started. Hundreds of revolutions in only a minute. As long as there is adequate oil and grease where it needs to be, It would be fine. If you are gently running the engine in case something goes wrong, well at that point if something failed while an engine is running it’s too late to save. Dropped valve, broken rod or rings. If you hear something not right and the engine was running you have already caused irreversible damage. That being any noise that a regular service could not fix like timing chain tightened, valve noise from clearance not within spec.
@@newtonmutea , thats your opinion, which you are allowed, but you are not allowed your own facts. But hey, go ahead and follow poor workmanship. good luck.
I abre a with @flexjay87. The video shows only a dessassemble and reeassemble. No craftsmanship in any part. That guy is careless with the inner parts. No analysis and markings in the pieces, for example, the conrods and its places. Man, if you dont take care of this things... bye bye engine in a short period of time, and you dont know what happened. Cause you are just a assembler not a careful mechanic. Its visible... by the way that is a hell of a engine! 18.000 rpm... if you dont take care of this things. The blow is certanly. Sorry for my english... Im learning.
@@EduardoHenrique-yl4jg it's a relaxing video to sleep, if someone wants to get a reference or to actually rebuild an engine he will go to another channel aren't that dumb.And I don't see any carelessness as you call, he used new inner parts, he used a torque wrench where he was supposed to use I don't understand specifically what is your problem I have definitely seen worse rebuilds, this is one is ok
@@apatbond2864 no bro I'm personally using Yamaha R15V2 nd it done 800000 kilometers and it's an 2011 model bike they are amazing in terms of performance nd reliability 👌😎👍
Im almost convinced that I should purchase a pair of split toe slides to rebuild my LS2 engine😄.. this was a good rebuild video and very relaxing to watch
I suspect that the saving grace here is that the piston speed isn't high on these small cylinders, a feature that helped Honda have decent reliability with their super high rpm engines of back in the '60s. A bigger bore, longer stroke cylinder engine develops much greater stress on the rings and piston and calls for a more gradual break-in process to give good longevity. Still, I see so many these days abusing engines because it's somehow "cool" and manly to do (like running an engine up to the rev limiter and holding it there with no load) and it's not encouraging to see in any way.

You did that before, didn't you? When you took that engine apart, I thought never in my life will he be able to put it back together again. But you did it! Congrats!
I have built a number of engines in my time and thats the first time I have ever seen someone rev one to redline on the first start. Not too smart. Nice to see you finally using a torque wrench though.
Impressive🤯🤯 You make it like seems easy!!!!! But it's not 😳!!! Good job sir👍👍 Im a car guy and i know that motorcycle engine are more tricky and complicated due to smaller size etc.
Agreed. No running it in, no heat cycling, no timing, no jetting, no carb tune, no changing the engine oil. Just rev the shit out of it in the first few seconds.
Took me 8 minutes into the video to realize you guys were Lankan, good job with the limited tools available! I won't dare touch the gearbox on a 6 speed inline 4 though 😅 Nice channel, keep it up!
I just would number the pieces of the same kind before removal in a way to be able to put them in the same position again, avoiding any swap, just a tip. Good job anyway.
