I am a mechanical engineer by trade having started my apprenticeship in 1969 with Vickers Armstrong. I have been a biker since I was 14 and loved motorcycle engines since then. You are a true reflection of our great heritage of invention. Long may you inspire us. Dave
This man is an engineering genius. So laid back and matter of fact about what he does. I could listen to him all day. He's the Bob Ross of the bike world.
He makes one feel like a total dumbass...on top of that 😐😁
@@randersson3672 You're not wrong. I've watched the Missenden Flyer interviewing him and he just amazes me. No plans, apart from in his head, no drawings, nothing. He just 'sees it working' and builds what he sees in his head. The man is incredible.
I can’t get over how AM takes a saw to two perfectly good engines and makes engineering porn.
No disrespect to Kawasaki engineers but why did they not extend their wonderful fours into even more wonderful six bangers.
We must have old souls, since you can spot guys like this instantly. Humility + mastery is part of it.
Who is Bob Ross? LOL
"So I bored it out and used a vfr750 piston"
Ah yes, the logical step
Absolute madman
And then must make new races for the piston rings….done! As you do.
How the hell can anyone give this man a thumbs down. The bloke is a genius. If he wasn’t such a nice bloke it would be sickening how clever he is.
Its the purists, The V12 and 6 Kwaka's ruffled some of them.
God bless you Mr Millyard.
simple Knockdolian12 theres 146 people that don't understand genius level mechanical engineering
Jealousy is a curse, my friend.
proper bloke he is. and not against some dad work, you gotta like the guy.
There are morons in all walks of life or they have fat fingers and pressed the wrong one.
I dislike Milly the way he uses a hand hacksaw, he makes me look pathetic 😂😂😂
As a former motorcycle mechanic and motorcycle workshop owner, I loved watching this video of a Master Engineer at work on one of Honda's most popular engines.
That copper gasket was a work of art!
I wonder how many times the gasket can be reused?
@@43mackmobile If annealed properly each refit, it'll probably outlast the bike.
Everybody wants a dad like him :)
His Masters Voice Well, HMV, don’t keep us all in suspense. If you know better than Allen, give us the benefit of your superior knowledge, rather than just trying a put-down. Treatment of magnesium is not an easy process, but it needs some kind of protection. Les
Damn, I want to BE him lol
@His Masters Voice honda did.....he shouldn't.
He my never be your dad, but ha can be your CZcams buddy.
Mine was but not with his aircraft background. He got me into fixing/ rebuilding cars and to this day I go to yard to get used parts either cheaper or that are no longer made.
I could watch you fiddle with engines all day.
Well narrated, like the Bernard Cribbin of the mechanical world.
I rarely comment on any video, but these are superb. Having seen many of your wonderful bikes over the years, I imagined you worked in a state of the art workshop. It's great to see good use of the BBQ and utility room sink. I'm always getting told off for such things.
Nice to see AM working on prosaic machines.. Like seeing Michelangelo painting his doorframes..
Mind you, Allen's XL engine has a VFR750 piston, an oversized liner & Kawasaki rings, so I imagine Michelangelo's door frames were a bit special as well...
.. true.. Once I got into the video I realized it wasn't so ordinary..
@@enhancesoutheast5964 Allan Millyard doesn't do ordinary Lol
This ist a very different comparison with Michelangelo.
Leonardo da Vinci is real better, by constrution of Mechanik Maschines and Systems.
well said
Best engineering videos on the net. The tools used here aren't outrageously expensive. What you achieve is an inspiration
This was the first of Allen's vids I ever watched and I was quite impressed he knew how to pull apart and repair one of these little engines.
Certainly was in for a shock when I checked his other vids.
Your son is a very fortunate fella to have a dad like you, Allen. Another thoroughly enjoyable video. Thanks for sharing.
The most used equipment in an engine builders arsenal...A BBQ and Swiss army knife..Who knew ?...Love your work Allen.. Honest, no nonsense, Pure engineering.
I have been rebuilding and modifying bike engines for many years and although I knew of you, had no idea of your expertise given your, forgive me saying, rudimentary equipment comparable to my own and low profile in 'my world'. As I spent very little time online prior to today's strange times I might never have spent the time watching all your videos. If this enforced lock down has shown me one thing, I have a lot to learn but unfortunately not enough time to get to your level. Respect and I sincerely hope this damn virus does not affect you and your loved ones.......it would be too great a loss. Kindest Regards and Best wishes, Paul.
And don’t take that poison vaccine. It will kill you faster than the “virus “. It’s all about control
@@hondaxl250k0 So true, lost a good friend with a blood clot from the oxford vaccine and he had zero health issues before. Don't know about control, incompetence and over reaction driven by personal avarice more likely.
Delusional gibberish
@@jessiepooch I do not respond to trolls normally but I will simply state....Paul Cosgrove MSc MM. Look me up.
@@paulcosgrove6160 I will simply state... Google says "No results found for "Paul Cosgrove MSc MM".
Genius at work , so down to earth , and no posh state of the art workshop yet does such technical stuff.
Hi Alan. Please keep making these videos, they’re brilliant. You have a very calming voice, and your skill and knowledge is as vast as the outback. Respect from Western Australia.
Brilliant. This lockdown has its benefits for us fans.
Hi Allan não domino seu idioma, mas esse tal de lockdown tá no mundo inteiro
Dear allaid wow thank you for doing what I was told too be touch much in NZ ?
I have long been fascinated by the incredible AM projects so this channel is an absolute treat. Many thanks for posting.
Alan is so methodical and calm when he works. No swearing or throwing spanners.(I am so envious)
Your content is better than anything found on the BBC. God bless you, Mr. Millyard.

We Need more Videos Like this!
At 2.53 I felt aligned and in harmony with the Great Mr AM as I too have an orange B&Q bucket in my workshop.
Made my day
Please keep these videos coming.
Back around 1964 my friend had a BSA Super Road Rocket, we were doing an engine overhaul when a more knowledgeable mate and his friend came along as we were putting the cylinders on. This guy suggested we cover the opening with cloth where the camshaft was to stop bits falling inside, great idea. We completed the reassembly and push started the bike, it soon started to billow out smoke. Then someone said, "did we take out the rag?" We all looked at each other, OH shit!!! We took the thing apart to fine the tattered remains of the rage still in the opening. I can't remember how we cleaned it all out but we did get it going again. We had many disasters in our bike maintenance. It was fun time riding and fixing the bikes with very little knowledge. We really needed someone with experience to guide and help us and a proper place to work.
I hope your son has listened and watched you wisely and appreciates your knowledge. Nice one dad.
"Dad, is there any chance you can machine a Suzuki piston to take Kawasaki rings to fit in my Honda, please?"
"No problem son! Put the kettle on, and I'll do it while you make a brew!"
Hi Allen, I machined the ring grooves on a big bore KTM piston on my Harrison lathe, nearly killed myself, guess who left the gudgeon pin in the piston which promptly flew out at speed when I started the spindle and parted my hair! An inch or two lower and I'm certain I would have killed me. I'm a tool maker with 44 years experience with my own shop, just goes to show you can get your guard down every now and then! 😁 good videos, keep em coming.
Did you mean Toolmaker, same as I am?
No problem you're fired and black balled from The Machinist trade
I left the chuck key in once.... only once
@@nearsightedfromthefarside6534 I did that in metalwork class at school in 1971. As you say - only once!
@@nearsightedfromthefarside6534 I was swapping a 4 jaw for a three jaw chuck. Just fitted the 3 jaw and tea break bell sounded, off I went. Came back and switched on the lathe.......chuck shot across the floor. Never locked the chuck in place.
Excellent! My mate had a dad like that…he was great! What a great oil filter! Love that Allan nearly always have his equivalent of the WW2 marine’s “Garand thumb”!
That was my first bike in 1974, all I did was wash it and change the oil.
I got mine around 1980 with low miles, but same thing, it required no maintenance. I might have adjusted the tappets just for fun, because I like to do that sort of thing.
Great work, that BBQ sees some engineering action.
Now I have another reason to upgrade my BBQ!
I'm surprised its a bought one and he didn't make it, on second thoughts maybe he did, he makes everything else look like it came out of a factory.
@Mr Brightside Try getting the smell of chain grease out of the kitchen when the boss is on the way home from shopping.
I was involved with Honda machines from about 1962 onward and served as a mechanic and service manager for 15 or so years. One of my favorites was the CB 160 which I owned as my own commuter bikes. I'd be interested in videos you might cover rebuilding the crankshafts of older small Japanese twins as it takes specialized tooling to be made and finding suitable spare bearings and crankpins. May not be much of a demand for it but these older engines were the bedrock of Honda design back in the day and were very sturdy and dependable.
Not only a supreme mechanic, but a great dad as well!
Usually, I would never bother watching these types of videos, but Allen Millyard makes it enjoyable and interesting.
Thankyou
beautiful job,i wish there was more like this on telly ,rather than all the bull____ that we get fed....programmes for car enthusiasts?? i think not...keep doing what your doing - great!!!
Thanks Allen, lovely, gentle, reassuring viewing in these troubled times. And nice to see you doing a simple little job that we mere mortals can relate to. Keep em coming.
So nice to have no special effects, unnecessary music or odd robotic voice. I also like the use of tools ranging from Swiss army knife and BBQ to lathe. I wish that I had stuff like Z1 pistons lying about and the mechanical competence and skill to fit them onto a 750 piston and then into a bored out XL175! My missus goes mad at a shelf of "To good to bin parts" .
I feel like I have just watched a genius at work. Effortless engineering skills. The position was a bit sloppy. So Allen has a rummage through his scrap box pulls out a Z Thos piston, takes the rings off and machines the piston to fit. Like it was nothing. I was just in awe throughout this video. It times gone by guys like Allen invented the telephone, electricity and the bouncing bomb from Dambusters. Just knocked up in his shed. I am now a super fan. Incredible
I love the way you are swapping pistons from other engines - well done!
Yeah, he put a piston with 4 valve relief cuts in a 2 valve engine. WTF? I pity that poor combustion chamber...
Back in my misspent youth when I raced an XL-175 I replaced the piston with one from a CB-350. Higher compression!
Just piston rings. He used the honda piston
Im sure Allen would have worked out if this was an Interference Engine and if there were any clearance issues beforehand.
@@mightress yeah but its a 4 valve piston in a 2 valve head.
@@michaelhayward7572 makes no difference for the rings, they just sit in a groove. Nothing to do with the shape of the piston.
Fantastic, a real eye opener. Can't wait to see the one on head gasket making. Could you also show us some more machining: Cutting piston ring grooves, boring out cylinders, fitting new valve guides and seats? Is it also possible to regrind bearing and cam surfaces, and do nitriding on the BBQ? If anyone knows it would be you!
I am a qualified time served (70's)mechanical engineer and biker since then and Allen is without doubt my most admired engineer and bike builder of all time
You are an inspiration. I was in the carport making a clutch cover gasket and realized I’d forgotten the scissors but, in a flash, I thought of you and pulled my Swiss Army Knife out et voilá. Thanks for saving me a delay.
Very instructive. At first time I was affraid that you add five more cylinders to this one...🤣
Great video Allen and thank you, you make it look so easy, look forward to the next.
A bit of a memory moment for me here. I had an XL175 back in the 1970s. I sold it when our son was born to buy baby stuff. That's priorities for you. :)
It was only a few months later that somebody gave me their old Suzuki 70 to get around town on.
A friend introduced me to your channel knowing I spend hours watching these type of vids after a 2-10 shift. You sir are an absolute genius and by far the best you tuber out there I’ve got to remind myself to breathe while watching on times you have me mesmerised, Thank you 👍
Loving the frequent uploads Allen, your work is truly amazing.
A Kawasaki 1000cc piston into a 175cc motor.
Now there's karma added to that Honda as well.
Thanks for sharing your passion for mechanics, mr. Millyard.
Is it now like a Suzuki TSCC, twin swirl combustion chamber, after all , it's got a four valve piston un a two valve head Lol.
Absolutely brilliant watching. Love the matter of fact attitude. Oh it was a big bore I had done, changed the vfr piston for a z1 piston, then altered the ring gap.
Tommy Cooper !!!! Just like that !!!
Allan, you are The Man.
Thanks for sharing.
Love the videos Alan brings back memories of working on my old CD175 twin, YDS7 Yamaha. 😀
Masterful, meticulous engine build. Would love to hear it when it's back in the bike. Well filmed with an clear and concise v/o.
I don't know how you do it Allen but I even find myself marvelling at your gasket making skills.
Can you draw stick figures with a pencil on paper ..if not forget it.
Allen does it again, but this time he triggers some old and fond memories as I bought a brand new Honda XL175 in 1977 it cost $729 AUD. It was my first motorcycle. The very first motorcycle I rode was a Honda QA50 in 1971. Honda and I go back that far. Also after watching a few of Allen's videos he has awakened a urge to make my own gaskets. The the two best tips I have learnt from these videos are to make my own gaskets and change the original screws to socket head screws. Yes, I had to buy an impact driver to remove the over 50 year old seized screws. The worst screw holding the two case halves together took over an hour of beating to remove.
Once again I thank Allen Millyard for his informative videos and reigniting my passion for motorcycles.
I wish you were my neighbor. really wanna learn the art of engine rebuilding with you.
Over on the VFR forum, someone posts:
‘One of our pistons is missing...’ ;)
If they are Millard fans it's great news. Think of the weight saving, plus now have an economical Honda V3 with integral cup holder!
Such a classic simple engine design but Alan takes servicing and tinkering to a complete new level of genius we could all just adapt a different piston we had lying around - not! 😮
Rather than cutting the gasket with a sizer, you can use the peen side of a ball peen hammer and tap around the edges, the gasket will be cut to exact fit. The same goes with the holes. Place the peen side of a small ball peen hammer over the holes and tap the flat side of the hammer with another hammer. Just a tip. Great video.
Thanks Allen, really enjoyed this vid. It was encouraging and vids like this inspire me to set out on my first motorcycle project. Keep vids like this up!
thats brilliant
Thoroughly enjoyed this video as expected 👍🙌🏴
Loved this video. 👍
I've just come across this blokes vlog who I recognize from shed+buried vlogs like this are just worth their weight in gold for blokes like me,when he got out the little brush for the gasket goo I was like amazing just GRT...loved watching brilliant a,b,c narration another comment said like Bernard cribbins, voice of my childhood 👍...
He's an engineering guru with an attention to detail that a lot of people can't relate to. Respect and admiration in spades.
Oh the relative simplicity of a single. I miss my SR500 so much!
Pyro1251 me too!👍
Legend in quiet work. Lovely.
45 years of rebuilding engines as a hobby always with access to a lathe and mill never did i think of swapping around piston rings or holding in gudgen pins with buttons not clips. Strange how now and again the penny drops when you watch a complete expert at work. Just like for 30 years to me wheel building was a black art until you see it on You Tube now I rebuild wheels. Thank you Mr Millyard engine rebuilding that contains engineering gold dust....subscribed.
What a fortuitous video - I have recently been given a 1976 Honda XL 175 ( in rather rough condition), and have learned more in 13 minutes than in several hours of internet research! Many thanks!
Why am I not surprised that Mr. Millyard uses the scissors on his swiss army knife to make his own gaskets? Of course that's what he uses, because he is making his own gaskets!
Ive had that swiss knife since 1998 and its cut every paper gasket for every engine ive worked on
if it ain't broke dont fix it.
@@AllenMillyard you must have sharpened those scissors a few times then. They look to cut really well
@@AllenMillyard Same here although I've also found some superb surgery scissors that do a lovely job as well.
I've found the most useful Swiss Army knife to be the Explorer. It is one of only 2 or 3 models (one other is the Golfer) that has the Phillips driver out the end instead of it projecting at right angles, much more useful. It has the loupe as well which is excellent for crack detection.
Tell you what though, I've not found better than Three Bond (Hondabond, Yamabond) engine sealant, and I've tried every gorilla snot there is or has been. I'll knock apart an untouched 50 year old Japper and the Three Bond inside the engine that squeezed in during initial assembly has never come adrift, swelled, or became brittle. It is in my humble opinion the best case sealant that is made.
In fact, I rarely replace gaskets, I simply remove the part, ignore torn gaskets, apply Three Bond, and bung it back together. They never leak, never.
I think if Allen Millyard were shipwrecked on Gilligan’s Island he could’ve built himself a workshop and not just a boat to escape , but it probably would be a V16 he built from scratch.
He is a proper fabricater
Brilliant Allen. Keep them coming the videos are great
What makes you think the clutch cover is magnesium
Crazy to have all that knowledge. Makes it look so simple. Vfr piston and z1000 who'd have thought 👍
You are a bloody genius and too reminiscent of my best friend who I lost in 97
Great instructional vid, more please!!
Nice job on that engine! 👍😎
An absolute pleasure to watch and no ridiculous rubber gloves!
Fantastic videos! I learned motorcy mechanics on similar engines as these. I'm nowhere near the level of skill of this gentleman. The first engine I took apart and never got going again was a non running BSA Bantam 2s in the 70s when I was in highschool. My second bike ran (barely). It was a Honda SS50 Fury, same engine as the one he restored in another video. The bike had no kickstart, so it always had to be pushstarted and no off switch, so it had to be stalled to kill the engine. The compression was so weak that you could spin the rear wheel in 1st gear by hand.. I learned how to swap a piston and work around the cam chain and set cam and points timing on that bike.
Good memories here. That 175cc engine is the predecessor of my current Honda XR150L..
Amazing, priceless and invaluable!
Great Video: Love these rebuild jobs its nice to see an expert in action would have liked to see it start afterwards :-)
OMG brother you are such a gentle soul and a awesome mechanic / engineer kinda a Hero to many in America TY for all you work and sharing
I always loved Honda's answer to the centrifugal filter. The British put that inside the crank shaft requiring and engine strip to clean out.
The XL always bemused me. Some parts are like a competition engine (mag covers, high comp, cam directly in head, big valves and relatively lots of revs) but then others are full on endurance designs - air cooling, nut and bolt tappet adjusters, points over cdi, oil spinner, etc).
Its almost like they were making two bikes at once.
My next tool purchase is a BBQ
Great stuff Allen Keep up the good work
I take it you already own a Swiss Army knife then?
@@ParaBellum2024 Yeah I've never used it to make gaskets though
Hi Allen. I have been watching for some time now. And I love your shows. The skills you have are a joy to watch. My uncle was 11 years older than me I was born 73.and whe I wa 6 and older. I was in awe of my uncles bike collections over the years. I took it for granted what environment I was in. But I loved it. I know now that I had a great childhood around yamaha and Honda bikes. And your shows remind me so much of those days. F'kin class in a glass. Thanks for sharing.
Excellent video, really well presented. Thank you. I'm someone very keen to learn how to better look after my classic bike & watching you work has been has been an inspiration. I'm really looking forward to your 'in the shed' series.
30 seconds in and this is my type of video!
great video
I’d love to know Alan, This man is a genius a Kawasaki God. Got my up most respect,keep up the good work mate👍
This man is so experienced that his arms have became a goddam torque wrench.... Love you man from India 🇮🇳
Your swiss army knife is a Victorinox Super Tinker if im not mistaken! very nice model.
McGuyver model you mean?
Or maybe a Huntsman which also has scissors
Oh dear.....
Looks like it's had a couple of cylinders added too.
it has plyers can't seem to see any in the latest cataloge with plyers, I bought mine in 1998
😂😂😂 The only person on the planet to use the Swiss Army Knife scissors. Brilliant!
No, I use them all the time. They’re nearly as useful as the bottle opener :o)
Nope, i use the hell out of mine. Brilliant little pair of scissors.
I went to buy a new swiss army knife and the guy in the shop said he had one with five blades and a bottle-opener. I asked him if he had one with five bottle-openers and a blade.
From Japan
I have been riding the XL250K3 for 43years.
Unfortunately, I gave it up now, but it was a very fun bike even without power.
Watching your video reminded me of my bike.
Thank you for the wonderful video.
High lighting of the working parts is spot on
Blimey im surprised you didn't make it in to a v twin! And fuel inject it!
LOL!
First thing I thought, V-twin superbike for Isle of Man TT races.. oh.. its just a quick rebuild.
Hahaha... well held Jools!
Yeah, I was just waiting on the hacksaw coming out, that's usually my favourite bit.
haha!!
31 dislikes !!! Are they NUTS ??
I would imagine they are purple faced with jealousy.. like me.. .but I totally Thumbed this UP!
Anyone who dislikes his videos are just jealous. This man is an engineering genius and the couple of immature jerks who have given these videos a thumbs down is just mad they themselves are not capable of such critical thinking
they must have a screw loose
@@PatrickKelly-lz3pv Yeah, all it needs is a lil tap here and a wiggle there. That should fix it.
Hi Allen. Many Thanks for your time and effort in filming and editing these videos. They’re so enjoyable and informative. Keep ‘em coming. Thanks again. Keep safe
Why are you so genius..work with common equipment..but the result is excellent....i think Japanese Will give you a citizen
I wouldn't miss this stuff for the world. I'm now subscribed!!! BTW I am available for adoption!!!😂😂😂.
Phil Morrow
Me too lol
And Me !!!!
Wish I had shed with all those tools but rent I so expensive in Los Angeles's suburbs
Phil Morrow me too,and I’m older than Allen!🤣🤣
The copper gasket could be heated in a toaster for uniform heating
May I barrow your toaster?
Red hot? What is your toast like, carbonized?
I thoroughly enjoy watching your videos Allen. Just goes to show what can be achieved in just a garden shed/garage and a bit of know-how. It seems like tinkering is an obsession for you too! Keep up the good work buddy!
What a pleasure to see you completing your task so thoroughly--thanks for sharing your passion!
The most important part of any shed work”TEA”.
No way... coffee is the future!!
@@wacker2286
Yep, we dumped our tea in the harbor, where it belongs. I'm going for another coffee, as we speak. LOL!
A 4 valve piston in a 2 valve head....you werent worried about clearance of compression ratio then!?
That's what I thought too. But if it's cheap & works then why not. I'm sure he would have at least checked that the piston cleared the valves. Perhaps due to the rather large increase in bore size the compression would still be ok, even with a flat top piston, and not requiring high octane fuel. Perhaps just a cheap paddock basher that they did not want to waste too much money on.
@@glennmerriman8382 he only swapped the rings not the pistons.
@@memybikeni9931 he swapped the original piston for a bigger VFR 750 piston some time previously, he is now widening the oil ring groove in the VFR 750 piston with a parting tool to accept the different wider oil control ring
Great series of videos Allen. I don't know what you'd do without that barbeque! This one was a trip down memory lane - I passed my bike test on an XL125 in 1984. Keep these up please.
Great video Allen , always a pleasure to watch you work.
Some watch porn, I could watch an engine being renovated any day !
Damn Man !! This is proper Porn. 👍
