- Episode 2 - In this episode I start the rebuild of my Kawasaki Z1B 900 engine building up the cylinder head and barrels. My aim was to clean, recondition and use as many original parts as possible if they are within service limit. This engine started and ran really well with no nasty noises before being stripped, but was cosmetically corroded with rusty screws etc from around 40 years in storage.
Thank you Allen for the calm progress you make. No music, no begging for subscriptions, comments etc etc. A breath of fresh air (smelling slightly of brake clean and oil!)
Don't forget the cup cakes 🎂
He's undeniable!
Should my son ever ask 'what does genius mean?', I will sit with him and watch your content sir.
I work as a full time motorcycle mechanic, i get home after work and the First thing i do is watch Allen build some engines, a honor to me
With this mechanic genius, everything seems to be simple. And his videos are wonderfull, no music, no noise , no stress.
I’ve never clicked faster!
Same!!
Ditto! 😂
same
😂😂
Funny
Not in a million years I'd have thought the trick with the socket and screwdriver to put the valve seals in place!!! Thanks so much for the education!!!
🙂
I like the tip on installing valve stem seals. The engine will be stunning with the clean finish. Enjoyed the video a lot.
your meticulousness to maintenance is addictive. it's a skill that is quickly being lost. many thanks allen.
In the seventies through nineties I did HUNDREDS of these KZ rebuilds having owned a performance shop. That was long ago. YOU brought me such a smile of familiarity going BACK to stock. I appreciate you.
Cleaned castings are indeed beautiful.
Back in the 1970s, who'd have thought there would one day be the means to view on demand a video about a Z1 engine rebuild!
If ever motorcycle maintenance was raised to the level of art, Allen is its grand master.
Spellbinding, as always, maestro!😊
I come for the Hedgehogs. I stay for the high quality engine building.
Best wishes, Dean.
Me also plus the Atco
Tip for removing carbon buildup from pistons / cylinder heads: paint stripper (Starchem Synstryp). Softens the carbon within 10 to 15 min, can be scraped/wiped clean easily. Also works wonders on piston ring grooves with a toothbrush. Doesn't effect the metal.
Going to try that! Spent a lot of time last weekend doing it manually, right after I picked up stripper to clean old paint off the engine 😅
The Z1 is a lovely engine inside and out. I've had four of these in the past. So strong and reliable. One of the best engine's ever produced.
My dad still has his 84 z1000 with power pipe and big block custom cams ect it's one of the best bikes I've seen it's unreal . Love this
Time moves at a different pace on this channel to the rest of the world. Not only does Allen have all the time in the world to get the job done "just perfect", but the stresses of my life get put aside while I'm watching Allen and suddenly 17 minutes have passed.
ep 3 is 20 minutes 🙂
The monster machines you create in your little backyard shop simply amazes me, Allen. As well as the level of precision even the most well-outfitted builders can't match. 😎👍
👍👍👍
I got an Allen Millyard notification and I watched the video this morning and it was just perfect.
👍👏👍👏
Those vapour blasted castings look good enough to eat! Your videos are an absolute treat. Thank you.
Absolutely amazing Allen !
Thanks for sharing, I was completely glued to this, you are the master !

Don’t know anything about motorbike engines but could watch Alan and his calm expertise endlessly,,,
I have been looking forward to this one, I rode one of these back in the 80s. Lovely bike, wish I still had it....
Took a break from building an engine to watch my hero building an engine. Cheers!
9:53 "Dad's vintage valve spring compressor". That's identical to my valve spring compressor, which I bought new in the '70s. Vintage? Cheek!
I always used a tuppence (two new pence - it was late 1971) coin at the screw end to prevent damaging the the head of my Norton 650SS.
Reminds me of lapping in gate valves in the boiler house back in the late 70's...
From Kentucky USA...Live forever, Allen.
I love your craftsmanship. No need for big special tools for every small job. Just a little time and engenuity. Absolutely perfect.
We are fortunate to have a vapor blasting machine in house. We use it nearly every day. I think a of a mutual friend every time I see a new video. I just texted Daniel Schoenwald to say hello. Life has been busy in the shop. A little too busy. I hope all is well with you. Be good. Remain safe and healthy. Wishing you a Deluxe day!
Daniel is a great friend
He is a great man. He and I have had conversations revolving around restorations. I understand you have had the pleasure of spending quality time with Daniel and his family. I reside north in Washington State. My wife and I are moving to the east coast to be closer to 2 of our 3 children. I am a bit older (1953). I am looking forward to investing more time with my adult children and my ever growing projects.
Good to see the hedgehogs as well. Our visiting badger turns up nearly every night to devour a big plateful of dog-biscuits. And has a good drink from a bowl of water.
Mr Millyard is back...
And what a Wonderful day it is...!!! 😊
I always loved an engine rebuild. It’s very therapeutic as the sum of all those parts takes shape and when it starts!! Heaven!!!
Thanks for bringing that feeling back and I don’t even need to get my hands dirty plus it’s all so beautifully done. Thank you Mr M!! 😁😁😁
Fun fact,I always click thumbs up even before Allen's video has loaded,or started... yep yep.. 💯
Great stuff ! - It's always a pleasure and a privilege to watch a master at work !!..
12:50 When I was rebuilding my Norton in the late '90s I took the barrels in to Pete Lovell Developments to be re-bored. Following the rebore Pete honed the barrels to a perfect cross-hatch, and gave me a copy of an academic paper of why such honing was a benefit.
I remember one day I was in Pete's workshop when he was using a mill, lathe, and drinking coffee simultaneous. I can barely manage one of those skills on its own - as my shirt front can testify.
Always an absolute pleasure to watch Allen at work and you can always learn something from the maestro.
I have been following Allan for more than 20yrs in the magasines.
Love the videos.
Great camera work.
Love to wstch.
Thanks for sharing.
Just this weekend I started measuring all the top end tolerances on a GS750, and following the description in my Haynes manual I measured 0.50mm piston to bore clearance where 0.06 is the service limit. Needless to say the description was severely limited and my interpretation of the process looked nothing like what I saw here, hence the ridiculously out of bounds measurement.
Allen, thank you showing that measuring method, and for once again (somehow) making engine rebuilds feel far less intimidating!
So therapeutic watching your videos Allen
My job as a kid was to clean under the ring , in the ring groove , you can get a big build up which can stop the new ring compressing
I love Allen millyard very knowledgeable and an engineering genius together with being such a great person
That's years of experience working, your such a joy to watch.
Superb! Enormous skill and dexterity, allied to a smooth and relaxing voiceover.
Nice honing tool. I work on a 40yr old Delapena machine. They call it vintage today, I remember it being new in 1983 lol.
You are my favorite motorcycle builder ! Like ALL of your projects !
Thank you for show us the correct form to rebuilt an engine. This is educational. Saludos desde la patagónia Argentina.
A masterclass of careful engineering re-assembly. This should be part of any tech college curriculum! :-)
Amazing video, Alan and Tracey's home baking, I could smell those buns. To see those little hedgehogs was epic.
I've just bought a Z1 so this is perfect timing
road traffic film remover (tar remover) cleans pistons a treat
Just beautiful therapy to watch. 🙂
Masterclass on top end assembly, very timely for me as I'm just pulling down my Honda 400 four engine right now. Thanks Allan!
Another superb video Allen,many thanks.And with Charley Weaver in supervisory mode it couldn't be any better.....apart from missing out on the cup cakes!! Just perfect
Kimbo
I could sit and watch this for days your like the David Attenborough of the automotive world
Great to watch, as ever. Thank you
I feel so chilled out after watching u work Allen 👍✌️
Brilliant
Thanks for your detailed and informative video. After watching your videos on engine building I have gained the confidence to tackle rebuilding my poor old Honda
I had some alloy parts for a vintage car vapour blasted once. They came back so incredibly clean and new looking they looked wrong on an old car so I had to dirty them up with some old oil to 'fix' them! It really is impressive how nicely it cleans things up.
Love the calm way you do these. Had never noticed the clock ticking in the background before, it certainly brings atmosphere to your vids.
It’s my 8 day wall clock
About to sleep and this is just what I need, a relaxing vid by a legend
Im new at this and am eager to learn about small engines... I appreciate all that you do.. i just asked my wife if she has any baked goods... i dont think she herd me.
Thanks again Allen. Time for a well deserved cupcake and a nice cup of tea.
Great work Allen, that vapour blasting is fantastic. The finish is better than new.
You're a living legend Allen
you aint wrong about the paste i worked for an engine shop and they would really look after their old paste as it was the best.
Thanks Allen. That's probably the most awesome motorcycle engine ever. I think it was Kawasaki saying to Honda "Oh yeah. You make a 750, so we'll make a 900." But, interestingly, I had a Honda S90, which is exactly 10 times smaller, and probably just as much fun. Now I have an e-bike and it's fun too :-)
I actually want a S90
@@AllenMillyard It's interesting that a small motorcycle can be just as much fun as a large one. Or maybe even more fun because it is lighter and easier to handle around town. But I would want the 900 on the highway.
I had a candy apple red S90 back in the early 1970's. (Use Google Images and search for Honda S90.) It was a really fun bike, and the girls thought it was cute and always wanted a ride on the back ;-)
PS - I thought you had an S90, or actually 2 of them joined together as a v-twin. But maybe I am thinking of something similar.
PPS - Nowadays I have an e-bicycle because my wife won't let me have a motorcycle, but that is really fun too.
Cheers from Canada :-)
I love watching the master at work
I'm really pleased with your videos and the cupcake from Mrs. Millyard together with a nice cup of tea is the bonus for us viewers. Thank you for sharing and looking forward to seeing more engine modifications and repairs.
oh god I have one of those rubber grinding tools - been a while since I use it on an old MG midget I had - ah memories ! 😀
Excellent as ever!
Looking forward to the cam timing!!!!
Always love the great camera angles!........puts is right there with you!.........thanks again for a great educating video!!
Thanks for sharing Allen look forward to the next video 🦘
Your videos make it achievable for us mere mortals , everything makes sense, Thanks Allen
That tip for cleaning valves is brilliant!
just be careful some PCB are made with fiber glass.
@@-IE_it_yourself I'd be wearing a mask, anyway. All that carbon dust is bad enough, but yes, I would say most, rather than some, PCB's are made of FR4, a type of fiberglass. You definitely don't want to breathe PCB dust at any time. I've got some of the old-skool phenolic boards, which should be great for this job. Also wouldn't want to breathe the dust from that!
@@gerryjamesedwards1227 thanks for the info!
i was also thinking the glass might be hard in a situation looking for a soft material.
@@-IE_it_yourself Abs plastic would be worth a shot if you were cleaning copper or brass like this, I would think. That's a 'hard' plastic that's fairly soft, but it might melt too easily.
Lovely precision rebuild. I still have my dad’s valve spring compressor just like yours LOL
Lovely to watch after a busy day and great to see such perfect reassembly. Our visiting hedgehogs are still feeding every night too.
Thankyou 🙂
Thank you for another wonderful video Allen 👍🏻
Thanks again Allen, I have a Z900, if I ever need to work on it these videos will help.
That engine is going to be a beauty.
Thanks Allen I love watching your work from Nz
I feel I am at the opposite end of the skill spectrum to you Allen! I will keep trying thanks to your inspiring work.
You’re so right Allen. I still have an original Chemico grinding paste tube of early 80s vintage. Works so much better than the new stuff.
great job again dale better than any tv keep it going
Thank you Allen, please keep them coming!
Dear god, they should put your engines in the Louvre or Guggenheim: they are literally art.
Mmmm never owned a z9/1000 but i got a Kz650 with Z750 e1 engine in it. Though its time for a fresh rebuild again. I think im gona drop the high comp and 810cc kit. Go back stock 738cc and turbocharge it. Those z1s are so nice and the Z air cooled kawa engines are BEATIFUL engineering
So relaxing and interesting look forward to next one.
That honing tool is lovely 😍
Nice job Mr. Millyard! Doesn't look to me like you need much help in the garage with your interesting projects. Now if Mrs. Millyard ever needs any help in the kitchen regarding her culinary craftwork, I will be happy to volunteer as a taste-testing technician! Cheers from Missouri.
I can sit days to look how you work on your bikes...very nice work...
I use grinding paste on my manual push mower blades. Very satisfying.
Oh, this takes me back to 1974, when my late stepfather tried to get me interested in what he was doing; at that time, it was lapping the valves on his Morris Oxford's engine. I regret to say that I wasn't impressed, though I did remember every detail, and still do.
Enjoy these uploads. Skills I could only dream of having. You sir are an engineer!
To organize small screw/parts, I usually use plastic ice moulds that we put in the freezer. They are great for working on small stuff like guitar screws, washers, etc.
Thanks for another extremely enjoyable video.
Nothing more refreshing than getting a notification bell from Millyard ❤. Best youtube channel ❤❤
Allways enjoy your videos!
Please Tell The Mrs. To Bake Those Cupcakes Sooner So You Can Have One During The Video! Thank You For Yet Another Engine Build Youtorial.
I am not a fan of motorbikes but I am hooked on watching Alan’s builds this man isa genius
Blasphemer, go away. Don't like bikes, get behind me Satan. Hehehe.
Love your videos Allen, just perfect!!!
