@@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.
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.

Hi Paul, thanks for the note. I'm so glad that my own story encouraged you to start wrenching. You'll likely make a few mistakes and screw up a couple of times (like I did!), but you'll learn valuable lessons in the process. Not to mention it's gonna feel great when that Yamaha barks to life again! Good luck on the build, and thanks for watching.
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.
As an old guy that loves riding I want to thank you for being here through the years for all of us on two wheels ! Good luck and come back as a guest when you can.
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.

Sir, this was one of the best videos I have seen.

I want to thank you for all the hard work you put into this endeavor; and good luck on a quick healing from your unfortunate accident.
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!
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.
Glad you guys did this video. When I bought my bike brand new I let it warm up and rode it how I ride it today. Almost 9,000 miles later I still do the same. *knock on wood* I haven't had any issues.

@@bobgc1954 "manufacturers"??? what do they know? a bunch of CEO's who want to make money, so they give us the wrong way to break-in our engines so they can make more money from parts :) :) :)
This guy is my favorite, i probably won't watch this channel upon his departure. Tough break with the firework, i hope it heals up nicely for you. Hope to see you around in something else✌
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.
Nice to see some facts to the old question,Every bike I sell I tell my customers to go out and ride it and try and wear it out.Not 1 person has done that yet.Shows how good the oil and manufacturing of parts is.Love modern motorcycle.Have enjoyed your hosting of the show best of luck in the next adventure.👍🇦🇺
Thanks for the painstakingly long process of assembling and disassembling the two engines. Yes I was surprised by the results too. I think the break in periods were a result of older technologies and tolerances. Today's robots make parts within tighter tolerances which help explain your findings. Hope you get well.
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.
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.
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.
Hellow. Two weeks ago I finished to rebuild the top end of my bike. I decided to go for the "brutal" metod. Just changed my oil after 20 miles. When i ran it I felt how the engine was getting stronger and responded better. Im happy with my results. Waiting for 500 miles for the second oil change now 😁😁😁😁. Harley 1200 sportster.
Really enjoyed this video and I'm so glad to see you guys finally put this damn topic to rest. I recently broke in a motorcycle and discussed this topic from my own personal opinions and it was pretty much the same thing that you concluded here. Just ride your bike, use common sense and enjoy the process :)
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".
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. On the K series, it made no difference, but each could just be the as-built variations of the engine. Hope recovery goes quickly, looks like it seriously hurt. Good luck in the new venture. I've got so much out of your vids, so thank you.
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!
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 .
Thanks mate, and greetings from the Philippines 🇵🇭 I must admit that I was totally unsure on how to break in my brand new KTM 390 Adventure 🥴. Now I am much more at peace and will just do what needs to be done, focus on riding it safely and getting used to the bikes overall handling without worrying to much and simply, just enjoy my new ride 😉 Good luck to you for the future what ever it may bring 🙏🏼👍
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.
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.
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.
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 .
Well thank you for this video, sad to see you go.... The garage won't be the same without you. But I've always believed a hard break in is going to shred the engine....
You came to the same conclusion my old boss did many years ago. He'd run the snot out of a new engine with the mentality that if built properly it'd be fine! I would rather find a problem early while potentially under warranty.
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.
Thank you for making this video. I guess we can trust in modern metallurgy, oil, and tolerances. I wonder if an air cooled engine would yield different results.
Very nice video. If the hard brake in had more ring wear, it might be due to turning more revolutions in the 1000 miles of riding. Good luck in your venture.
The best most presise and complete and unbiased video on the internet right now about engine break in Thanks bro we really enjoyed every video of yours THANK YOU ...👌👌

I didn't actually notice the scar until you mentioned it.. sad though that you're going away .. you're smile's the only thing missing compared to your previous videos.. best of luck my friend

I bought my brand new Honda Shadow at a dealer nearly 3 hours away from my house. I rode it home in rush hour traffic and over the past year I’ve put 25,000 miles on it and no issues or problems.
I recently bought a brand new motorcycle keeway k light and i didnt know about the engine break in specification from the factory and i have been riding it hard for 100 km so this video assured me that i hadn't ruined the engine (yet)
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.
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. ;-)
This makes me feel better. I am a beginner rider. I bought a 2020 Kawasaki Vulcan S. I have been riding to the best of my ability. I haven't gone any higher than about 6,500 or 7,000 RPM. I'm at only 320 miles total. I have done mostly city riding and lots of parking lot practice. I am going to wait till 600 miles to change the oil. I have Royal Purple waiting to go in.
Excellent video, I like your opinions I agree! Only bike I bought new was a 1997 Suzuki RF900R and I broke it in as manufacturer specified. Rpm limits per certain amount of miles but didn't say anything about how much throttle up to that rpm limit so I accelerated as i wished but short shifted at specified rpm. Serviced as recommended. Always ran great for me!
I think you missed the purpose of the "brutal" route. The idea is to put the motor under a heavy load (heavy throttle in too high of a gear and engine breaking). Higher RPM is more like the "by the book" but louder.
I always let the engine idle for a bit to get some heat, ride it slowly and calm until it fully heats up and then I start giving it the beans, never had issues not even with 2 smokers
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 .
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.

Very true!
I am sure MC Garage have more understanding of engines than the manufactures do. Right or Right???
@@bobgc1954 "manufacturers"??? what do they know? a bunch of CEO's who want to make money, so they give us the wrong way to break-in our engines so they can make more money from parts :) :) :)

A bunch of CEO’s that lead some pretty big and very talented engineering teams
Stupid comment
Best wishes on your new adventure Ari, greetings from Mexico!
This guy is my favorite, i probably won't watch this channel upon his departure. Tough break with the firework, i hope it heals up nicely for you. Hope to see you around in something else✌
Recently started watching this channel and now I find out one of the best mechanics to give video tutorials left the building almost two-years ago.
What effect did that hunk of foil seal that went into the crankcase @ 4:52 have on engine longevity?
Oh man that’s funny 😆
I hope they had a mesh screen at the bottom of the funnel.
Lmfao that's hilarious.
I had to slow it down to .25× to see that foil! That was a great catch!
Bought used boat that would run 10 mins and die.
Found 2 foil tops in gas tank, after pulling out and cleaning with garden hose.
More power to you dude. Your successor is going to have a lot to live up to. You will be missed.
Thank you. Been in power sports for 30+ years. Kind of always thought this way, and never broke in anything mildly. 👍
good info, get well soon sifu. all the best on your next venture ..
Wow bang whyzul kat sini lah 🤣 idola

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.
Nice to see some facts to the old question,Every bike I sell I tell my customers to go out and ride it and try and wear it out.Not 1 person has done that yet.Shows how good the oil and manufacturing of parts is.Love modern motorcycle.Have enjoyed your hosting of the show best of luck in the next adventure.👍🇦🇺
Gonna miss you Ari? thank you for sharing your knowledge with us.
Thanks for the painstakingly long process of assembling and disassembling the two engines. Yes I was surprised by the results too. I think the break in periods were a result of older technologies and tolerances. Today's robots make parts within tighter tolerances which help explain your findings. Hope you get well.
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.
How about downshifting?
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.
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.
Man you guys really went all out for this video. Major props, heal up my dude!
As long as the new guy is not Matt LeBlanc, will stayed subscribed. Good luck in your new adventure.
Don't say that. Chris Evans would be much worse.
They need Lemmy and Spurg from RevZilla!
Sorry to hear about your accident! Good luck with your new ventures. Thanks for the uploads
Hellow. Two weeks ago I finished to rebuild the top end of my bike. I decided to go for the "brutal" metod. Just changed my oil after 20 miles. When i ran it I felt how the engine was getting stronger and responded better. Im happy with my results. Waiting for 500 miles for the second oil change now 😁😁😁😁. Harley 1200 sportster.
this is one guy who made me like bikes and riding more and more... hope you get better soon... bye and good luck with your future ventures...
These MC garage videos have been my go-to for motorcycle education. Thanks for all if it.
Really enjoyed this video and I'm so glad to see you guys finally put this damn topic to rest. I recently broke in a motorcycle and discussed this topic from my own personal opinions and it was pretty much the same thing that you concluded here. Just ride your bike, use common sense and enjoy the process :)
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".
@@Jeff-Vader_head_of_catering cool story bud
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. On the K series, it made no difference, but each could just be the as-built variations of the engine.
Hope recovery goes quickly, looks like it seriously hurt. Good luck in the new venture. I've got so much out of your vids, so thank you.
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!
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 .
So sorry to hear about your accident hope you're healing well watch all your videos you're great!
Thanks mate, and greetings from the Philippines 🇵🇭
I must admit that I was totally unsure on how to break in my brand new KTM 390 Adventure 🥴.
Now I am much more at peace and will just do what needs to be done, focus on riding it safely and getting used to the bikes overall handling without worrying to much and simply, just enjoy my new ride 😉
Good luck to you for the future what ever it may bring 🙏🏼👍
Aba teka
Get well soon Ariel!!
Good luck with the new project.
Regards from Oaxaca
México. 👍🍀
Im pretty sure he's fine now. This an old video......
I Purchased a New Kawasaki 636 200 miles from home. Rode at 8000 RPM the whole way. Time will tell! Great video!
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.
Get better soon bro, thanks for all of the knowledge you have given us.
Will miss you bro.
Your delivery style and accent is best for auto show imho.
All the best
Best wishes for your recovery, and your new career
Get well soon. My sympathies with you. Bless your journey ahead. Just play safe. Dont mess with things that are not safe.
This video deserves more likes and view. All that work to compare two motors and breaking em in takes dedication.
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.
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.
I bet, it will never be the same ever again.. I feel sad mate, will miss you guys.. best of luck for your new adventure.. 🍻🍻🍻
Ari!!!!!!! I'm going to miss you man. This is my favorite MC show on UA-cam. I'll look out for you on your new platform. Peace and heal up.
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 .
Enjoyed all your vids and explanations about stuff I didn't know. I pray for you to get better soon. Be safe and thanks for everything.
Well thank you for this video, sad to see you go.... The garage won't be the same without you.
But I've always believed a hard break in is going to shred the engine....
You came to the same conclusion my old boss did many years ago. He'd run the snot out of a new engine with the mentality that if built properly it'd be fine! I would rather find a problem early while potentially under warranty.
Great ad for firework safety!
Fantastic fact based content. Just got to MC garage but will watch the rest! Thankyou
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.
Thank you for making this video. I guess we can trust in modern metallurgy, oil, and tolerances. I wonder if an air cooled engine would yield different results.
Just started binging his old videos and then came across this one. Sorry to hear about the accident! Some firewalls are not joke. :(
Im really glad it popped up in my head to look up a proper break in procedure. Buying a new motorcycle had me a little nervous. Thanks!
Very nice video. If the hard brake in had more ring wear, it might be due to turning more revolutions in the 1000 miles of riding. Good luck in your venture.
Get well soon. Great videos 👍
The best most presise and complete and unbiased video on the internet right now about engine break in
Thanks bro we really enjoyed every video of yours
THANK YOU ...👌👌
Never knew about the fireworks mishap. Dang dude! Glad you recovered and came back! You are the reason I watch this channel as much as I do. Great host! Cheers!
I didn't actually notice the scar until you mentioned it.. sad though that you're going away .. you're smile's the only thing missing compared to your previous videos.. best of luck my friend
Thanks, and I'll stick to gentle by the book break-ins.
Great video! Whoda thunk? So sorry to hear about your accident. Wishing you a complete and speedy recovery!
Apply a lot of aloe vera, the scar will heal better that way, I'm glad your jaw is better, i can tell you have an Stallone ish look to it now, you'll only get meaner from now on, don't forget about the aloe vera, it's cheap and it's very effective.
Or smoke one ;) I had such a shit as well.. the skin burned if you touched it and it looked like many filled pimples
One or two days later it was nearly healed of (I used some cortisone cream a few days ago and it got better but not that good)
emu oil!!! seriously talked to a guy at a burn center once and they swear by emu oil....look up before and after pics about emu oil. Its a miracle. Good luck brother....keep on, keepin on. !!!
I bought my brand new Honda Shadow at a dealer nearly 3 hours away from my house. I rode it home in rush hour traffic and over the past year I’ve put 25,000 miles on it and no issues or problems.
I recently bought a brand new motorcycle keeway k light and i didnt know about the engine break in specification from the factory and i have been riding it hard for 100 km so this video assured me that i hadn't ruined the engine (yet)
Thanks for the fact base not opinion based video. Great job.
We love you Ari, thank you for everything. 🙌🏼
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.
The question is: how do you normally ride them? Lol
@UNFINISHED FOOTSTEPS ok kid
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! 🏍
I always forget i ride full throttle.
Legit the best motorcycle channel ever made.
This makes me feel better. I am a beginner rider. I bought a 2020 Kawasaki Vulcan S. I have been riding to the best of my ability. I haven't gone any higher than about 6,500 or 7,000 RPM. I'm at only 320 miles total. I have done mostly city riding and lots of parking lot practice. I am going to wait till 600 miles to change the oil. I have Royal Purple waiting to go in.
Damn that looks nasty, wish you the best love your videos explaining everything
Awesome. I've always wondered about engine break in.
What about heat cycles? I feel like a wicked important part was missed here
Thanks for being a great host. Best of luck and take care. We will be looking for you on Motor Trend.
Excellent video, I like your opinions I agree! Only bike I bought new was a 1997 Suzuki RF900R and I broke it in as manufacturer specified. Rpm limits per certain amount of miles but didn't say anything about how much throttle up to that rpm limit so I accelerated as i wished but short shifted at specified rpm. Serviced as recommended. Always ran great for me!
Wish you a speedy recovery mate 🙋🏻♂️
We will miss you 😔
Love from India ❤🙏🏻
I think you missed the purpose of the "brutal" route. The idea is to put the motor under a heavy load (heavy throttle in too high of a gear and engine breaking). Higher RPM is more like the "by the book" but louder.
Never cared about breaking in, just ride it. Casual downtown riding is good enough, you can't go full throttle for too long anyway.
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.
Heartiest wishes for a very speedy recovery, your videos are best!!!
I’ve always just ride it easy for the 1st 200 miles and after that it gets ridden like I stole it. Never any issues after 50k miles
I always let the engine idle for a bit to get some heat, ride it slowly and calm until it fully heats up and then I start giving it the beans, never had issues not even with 2 smokers
