Busting The Engine Break In Myth | MC Garage

[@specialse]

After 20 plus years as a factory Honda motor cycle tech , at pre delivery inspection and road test , trust me , most new bikes have already seen the upper rev range before the customer gets it .

[@AriH211]

Yup, I'm aware of that. But just saying so doesn't satisfy anybody. We wanted to do some actual testing to inject some data into the discussion.

[@mareksumguy1887]

@@Cp3_james They don't run them hard at the factory; they use light throttle and go through the gears just to make sure everything is mechanically sound. @specialise wasn't talking about that. He was talking about what they do to the bikes on HIS end (after they have left the factory). Thats what i wanted to know.

[@mareksumguy1887]

@@Cp3_james 1. We don't know what throttle position (power level) those engines are run at. 2. Not all manufacturers do this. I'v seen video of Honda factory dyno their CBR1000RR at the end of the assembly line. And they only ran it at low throttle just to make sure there were no obvious problems. Not even half throttle. The engines definitely aren't broken in at the factory. And even then, i don't think they dyno every bike... they batch test them. Like 1 in every 5 or so.

[@PMitchell106]

6:09 A third possible reason for long break-in recommendations is that if the manufacturer can convince you to ride gently early on, they are less likely to have to repair anything on warranty.

[@ProPatriaRO]

Ok, as an engineer (propulsion specialist) my opinion on this is the manufacturer recommends breaking in the engine slowly because the chances of defects in the materials or manufacturing are still there and failing at 3000rpm with destroy the engine but most likely will not kill you, now 13500rpm and 100+ mph, having a piston blow, stoping your rear wheel will most likely kill you. I actually went through something like this, an intake valve seal failed and because i was at low rpm, was able to drive to the shop with no major damage done.

[@DonnDIY]

Best of luck to you in the future. Sorry to see you leave.

[@acdii]

This is so true with all modern day manufactured engines. The manufacturing has become so precise that tolerances are nearly identical from one engine to another, machining has improved so much that parts no longer need to wear in. The only ting that does need to be done correctly is to seat the rings, which is done in the first few miles, or in some case, on the assembly line before the engine is even installed. What DOES need to be properly broken in, not so much on a bike, but in cars and trucks is the transmission and final drive. Ring and pinion do need to be broken in properly of they would get abnormal wear patterns, become noisy and eventually fail. Same goes for manual transmissions, yes kids, they do exist. Overall, I am really glad this video was made, it backs up what I have been saying for years. Just drive it! If it's gonna break, it will break no matter how you drive it from the start. The only exception to this rule would be hand built performance engines that don't use factory parts.

You analysis at the end about the reasons for a "break-in" period is right on the money - it's in case something comes apart in the early life of the engine. I'll admit that I hadn't considered the engine mapping as a factor or the more modern materials with more advanced metalurgy so that has all added to my understanding. Outstanding video, well done.

WOW! The soft-break-in engine impressed me! ALL engines are broken in roughly - first start, from factory, they warm up the engine then do a full dyno run, 1,2,&3rd. Twice! SO - point is, what impressed me the most is that an engine that did not get its proper wide open first start (which is what they did, when they built the motor themselves, no dyno) I was impressed that it seated the rings at all!! :D Different strokes for different folks, I guess :) I prefer a "proper" break-in, but the southern version of "proper" lol - not rough, but also not gentle, neither - I don't need to hit redline right out the gate, but get on it!! Keep the RPMs varied, downshift a LOT to maximize blow-by protection, and don't be scared of 'er! Do it right & you can really feel the moment that all the parts hook up!! It's like hitting the power band on a 2-Stroke, and your engines will last you forever!

[@HIGLEGaming]

not even close to "every" factory does that. they also don't dyno every engine. that's a waste of everything lol. and they most definitely don't max it out. they normally just cycle thought the gears lightly to see if she's workin.

Thanks for the painstakingly long process of assembling and disassembling the two engines. Yes I was surprised by the results too.

Great to actually hear it from the top! I found a harder break in with BMW twins seemed to give long-term better mpg, performance and less oil use.

[@Jeff-Vader_head_of_catering]

Agreed. I like his final point of not just the engine breaking in, but the tires, suspension, and you getting used to the bike too. Very good points. As for the controversy, what I've come across is a lot of 'know-it-alls' who don't have a degree in anything, let alone engineering, spouting their opinions as fact, and calling anyone who differs in opinion, every curse word you've ever heard. Clearly, these are highly intelligent individuals. 🙄 For myself, I look at it this way: If the manufacturer is recommending the process, and ultimately it's going to be the manufacturer who is responsible for replacing any parts (or the entire engine) if anything fails after following their recommended break in process, why not just follow it? It's only 600 miles. I bet there's already someone typing the response "but if they can't tell if you broke it in hard, then..." They can tell. This video talked about there not being any discernable difference in the parts, he didn't say anything about there being burned oil on valves or cylinder heads, which is a dead giveaway for excessive heat and rpm. To each their own. I'd just much rather know that I'm definitely covered under warranty, than be told "sorry, you didn't follow break-in procedure, and thereby voided your warranty".

Wow! That's a really strong engine. I did a really hard break-in on my new Bajaj CT-100b, right out of the store. Revving the engine up in all its four gears. After only two hundred kilometers the engine became noisy, clickity clackity. When brought to the service center, they said the tensioner loosened up, creating the clackity noise. They simply adjusted it to tighten it, as they said they did, and the noise lessened, but the engine doesn't seem to be as quiet (regardless of the exhaust noise) anymore as it was when I rolled it out the store. Lesson learned, follow the manufacturers' recommendations.

[@howlinhog]

The only time I know of (professional mechanic for over forty years now) for being critical in regard to "break in" is for flat tappet motors. Back in the day when every automobile motor had flat tappets, pretty much all motor oil had a high zinc content, so you never had to think about it. Nowadays you have to specifically look for it and stay with it. Motorcycles have had roller lifters in pushrod motors for a very long time so it was never really an issue. Anything with overhead cam where the rocker makes direct contact with cam lobe and valve stem does not need a break-in, nor has it ever.

[@christophertyacke6019]

Great informative video. I'm currently breaking in my Z 650 RS and I have taking the approach of easy does for the first 100 miles of no higher than 4000 rpms with various speed, RPM and shifting with plenty of engine braking and using 1/4 throttle. I'm 200 miles in and now I'm increasing the rpms with higher speeds not exceeding 6000 rpms and continuing the other parts I mentioned as well and going to 1/2 throttle until I reach the 600 mile break in service. After the break in service I'll continue to increase the bikes capabilities until I reach 1000 miles do another service and call it a job well done and enjoy my bike worry free .

[@The.JZA.]

I’m breaking in my new CB650R right now, up to about 100km ridden so far. I was pretty gentle with it for the first 10-20km and then as I got used it it I started riding it similar to how I ride my old bike but just without any WOT and only revving it to like 2/3rds of max rpm at the most. I’m kinda just riding it at medium pace and varying the rpm, gear etc and making sure I don’t lug it at low rpm. Really enjoying it so far and I can’t wait to wind it out to 12,000rpm. Even the taste that I have gotten so far is pretty delicious.

Glad to know I won't need to worry about the engine too much. But still, moving from almost pure sportsbike to a naked bike means I need to re-learn the handling so the suggested soft break in from manufacturer works for me, except I can feel at ease now pushing the engine to redline once in a while.

[@MEEK5]

This video deserves more likes and view. All that work to compare two motors and breaking em in takes dedication.

[@mpc07005]

The only indicator I would expect to vary would be surface finish characteristics (not just Ra, either) and initial wear patterns, which weren't discussed. Break ins are intended to control these parameters in sliding and mixed friction surfaces of the piston walls, the various plain bearings, and transmission gear faces, and ultimately impacts how the elastohydrodynamic layers of the lubricating oil films form on these surfaces. Large dimensional changes of the components are not what break-in if for, if there was a problem with the metallurgy (gross dimensional stability) a break in would not have any affect for typical materials used. It would also be more interesting to see on a 'lesser' motor, it is very possible that Honda tolerancing is sufficient that no real break in is needed, which is the case with many modern engines.

[@thonczarenko]

This has always worked for me resulting in long lasting high performing engines. Hard acceleration and the lower gears (1-3) in short bursts is critical for the first 30 miles (rings seating), while letting the revs come down slowly with closed throttle to pull out any break-in particles. Do not lug in higher gears due to the bearings breaking in during the first 600 miles.

[@simd510]

How about downshifting?

[@magicdaveable]

I think the video presents some really interesting points regarding engine technology, the fact is that specific design differences are an important consideration. For instance, when I rebuilt my Porsche 914 engine and replaced the cast iron cylinders with nickasil lined aluminum cylinders "ring seating" was no longer a concern and revving to redline wasn't an issue.

[@adamcolbertmusic]

I really appreciate this video! I just got a new top end for my 66cc 2 stroke motorized bicycle 😁 I was wondering why exactly - or IF - the break-in was REALLY as important as they say. For example, I don't remember my dad EVER breaking in a new lawnmower....... always just put oil and gas in it and used it! I'm still going to try and be easy on my engine though. It's just common sense that the less strenuously you use something, the longer it will last. There are lot more moving parts than just in the top end, of course. That being said, this video gives me more peace of mind about occasional high revs on a new top end! Thanks for taking the time to do it!

[@andrewsanders6270]

I've been a machinist since I was a kid , and a motorhead. Good video. Truth is if something isn't engineered and or machined and or assembled , properly there will be above average / premature wear. If it is done properly there won't. The valve face and seats will beat themselves in slightly within a couple minutes, the rings and bores same . Bearings and bearing clearances are either write or wrong. There's no magical best way to do it . I say run them easy = no more than half throttle for 1st half hour , change oil . Run it up to 3/4 throttle half an hour and change oil , then start nailing it whenever you want. If it was such a big deal new cars and bikes would have alot of problems and they don't because modern materials and machining and finishing practices are so good. Bores are soft honed to reduce acsesive wear and heat , and what is just as responsible for sealing rings as bore and ring face quality, is the gas pressure behind the ring or rings that pushes it out towards the bore wich is why larger rather than smaller ring gaps are bennificial. Lastly overheating a new engine in particular is the worst thing for them . Really they're either write or wrong .

Been riding for most of my 36 years. I have never bothered breaking in any bike. I just ride them how i normally would. Looks like i was right all along, lol.

[@jponz85]

The question is: how do you normally ride them? Lol

@UNFINISHED FOOTSTEPS ok kid

[@Dave-sw2dm]

Most original owners don't put enough miles on a bike for it to really matter. The most I have put on a bike is 60,000 miles. The next owner might see some issues at 100,000 miles. ;-)

Consistency and proven record worked for you. If it works then why change it? 👍 Ride On! 🏍

[@kungfu2toe]

That's crazy! I feel like I've been lied to my whole life 😂 Sucks about the injury!

Great information. Now I know not to sweat it if I happen to open up my new motorcycle a little bit here and there. While in the break in period.
