Millyard Kawasaki H2A 1000 four cylinder - Maintanence tips and ride

- เผยแพร่เมื่อ 30 มิ.ย. 2024
- In this video im talking about a 1973 Kawasaki H2A 1000 four cylinder that I made in 2016. The engine produces 120 bhp and the bike is exciting to ride but is always trying to go faster than you should be! The engine was originally a 750cc triple which I re engineered into a 4 cylinder by adding one extra cylinder top the left hand side. The video has its usual wildlife and cooking interludes where Tracey is making cakes, and is looking after the hedgehogs and birds. Hope you enjoy this video and if you could subscribe that would be brilliant, to help me achieve my next TH-cam milestone.

I love the way that Alan talks about converting to a 4 cylinder as if its the simplest thing in the world. A true craftsman.
Allen. 😉
@@humandroid53 Oh yeah, I never noticed that before. My wife was right after all, I never read anything properly.
After that he shows how to replace the battery :-)
Hi Alen ,That's a clean exhaust when you open it up,you reduced the oil pump? I had the Suzuki GT550 two stroke triple and it was smokeless around town but on the open road 60 and above a lot of smoke for 10/20 minutes.Also that sound quiet compared to my four exhaust pipes,centre pot splitting into two little exhaust pipes
Truly amazing talent and finished product.
I don’t think Allen even realizes how amazing he is. I personally don’t know anyone who comes close. It’s not even the lack of tools or a spotless million dollar shop. It’s the seemingly total lack of awareness of how cool he is.
Well said Derek !
Anyone else who used a hacksaw to cut an engine into two pieces would not end up with a brilliant 4 cylinder 2 stroke that is for sure..
Well now he knows. I hope this doesn't spoil videos going forward. Or builds for that matter.
When I tell others about Allen's channel I let them know ahead of time that Allen is not a mechanic but an artist who works on motorcycles. That's how I see him, the fact that he enjoys a homemade cupcake is just icing on the cake.😇
i totally agree
Watching Allen tinker with his eclectic collection of bikes, he could just as easily be telling you how to look after your roses. No loud music, no shouting or revving the nuts off the bike. Just his soothing voice explaining clearly and precisely what he's doing and why. Oh and the cake, mustn't forget the cake.
You are the Bob Ross of motorcycle mechanics. You bring a Zen feeling to Motorcycle Maintenance.
I've finally realized that Allen is a cake guy with a motorcycle habit.
He has his cake and eats it too...
Cake, food of the gods
You sir, are an absolute gentleman. Everything about this video made me smile. Especially the sound of that 1000/4. Thank you.
Love that sound!
Holy moly that sound! It just SCREAMZZZ!!!
Just needs 1000 badges !!
Well done mate, Kawasaki would have loved you in the 70s
I worked in the R.A.F. with some fastidious engineers but this man takes the cake, he's a bloody genius and a gentleman
If someone didn't know any better, they would think the bike came from the factory as a four cylinder. It is amazing how Allen makes his modified bikes look like a factory produced product. Modifying something in one thing, making it look this natural is something else. It's always fun to see the helpers around the yard, too.
It's what I like the most about his projects...the attention to the smallest details.
In person they look so much like a factory product that you might miss the fourth cylinder at first!
Cut the engine with a Hacksaw. Epic.
There's something therapeutic yet infuriating about Allen's videos. On the one hand, seeing everything working just so perfectly is absolutely wonderful. On the other, I've been trying to get the center cylinder on my 400 triple to run correctly for years, and I'm just too stupid to make that happen, while Allen is building whole motorcycles with a hacksaw and a roll of sandpaper, and they run like Swiss watches.
Is there any possibility that the crankshaft of your engine could have been rebuilt by someone without much experience of this model? At least some of them have the crank webs fitted to the main journal sections by friction only, no splines or key. Without special tools, or having put the crankshaft into a lathe and scribed a straight line along all the crank webs before dismantling it, it becomes very likely that the cranks are not properly set at 120 degrees to each other and if you set the ignition timing by the marks on the generator rotor it could be way out on the centre and/or right-hand cylinders.
The same applies to Suzuki twin and triple 2-stroke engines, but not to Yamaha twins as they have splines.
@@cedriclynch The guy that did my crank has been the go-to for 2-stroke cranks in the area for the last 50 years and has an excellent reputation in the vintage bike community. If it had been anyone else I might have my doubts, but Charlie has done hundreds of Triples. I've also monkeyed with the timing quite a bit, beyond simply following the marks. I can make the bike run worse, but not better! Lol.
Great suggestion though.
@@JETZcorp Another few suggestions: (1) fit precious-metal-tipped spark plugs if you haven't already; (2) with the engine idling, slightly pull the throttle cable of one carb and adjust the mixture screw of this carb to get the best response; then do the same on the other two in turn. (Is it possible that the middle cylinder is not firing at all at idle, possibly due to a blocked idle jet or an air leak into the inlet stub?)
On some Kawasaki 2-strokes I have worked on I have found that the ports are very badly finished; the passages in the cast-iron liner and the aluminum jacket do not line up. In such cases some work on them with riffler files can work wonders for smooth running and give more power as well.
I tried to fit an MZ 250 with a Mikuni from the Suzuki GT500. It was virtually a straight swap, but refused to run right. I was convinced it was running weak but nothing worked. Then on (yet) another test ride it ran out of petrol and for a few moments the bike went like stink. It had been running rich all along and I made the basic mistake of assuming the original jetting was correct. Sadly, there were no jets available for that old carb so I put the bike back to the original. At least it was usable.
So check your carburettor. It might be nothing to do with the ignition.
@@davidelliott5843 Yeah, I've been all through the carbs. It does definitely feel like it needs to be leaner, but it's strange that it's rich at all throttle positions until a certain RPM. But the carbs are pretty crappy and best up in general, so I've been considering replacing them.
Allen, you are the tonic this world needs. Humble, kind, skilled, just amazing. Love to watch you work.
Motorcycle engineering, Wildlife, Home cooking and a test ride. What a perfect way to spend the day. 😊
Engines, cakes and cute animals, should be 10M views!!
yes would be cool to get 10M views on one vid
It's not all too long ago that Allen had just 23k subs, that was about 12 months ago when I subbed.
I was surprised by the lack of subs.
Yet again, you've put a smile on my face. Cheers Allen.
pareil pour moi !
Smiles per Allen 😆
same here, bikes & cake, perfect...
@@emil55555555ha ha
You've done what the factory should have done (but they couldn't handle the lawsuits) The engineering on this bike from adding the extra cylinder to the hand crafted pipes is mind boggling. The sound from the bike on power is unique. Great job on the bike and video and thanks for sharing it with us (I'd ask if I could ride it but I would probably kill myself).
You manage to make complicated look easy. That’s true talent. You should have your television series.
Its easy to be complicated but hard to be simple👍
He is involved with the motorbike show but i agree
@@williamluckhurst5646 I know he’s involved with Henry Cole. Although it would be preferable if he
had his own tv series.
The cake looks great, the bikes not bad ether, I bet she cook’s better than him, this mans from another planet, you have to see it to believe it
He basically does have his own tv series right here on YT. Having a series on actual tv is probably way too much work.
I wish i lived in Mr. Millyard's neighborhood. Seems as nice as Mr. Rogers, but, added benefit of custom bike work.
And delicious cakes!
"We´re going to need a bigger boat," -- Jaws.
"We´re going to need another cylinder," -- Allen Millyard.
Oh, and some fruitcake.
I´ve patched up a few old bikes and even butchered a few, but this man is both a surgeon and an artist, and there is a massive amount of knowledge and skill involved here which impresses me no end.
And having always preferred the smaller roads, on everything up to my BMW R100RS, I like the way he builds big bikes for little roads.
There is such a difference between gearing up for your ride, getting everything right, and having a good blast, and riding to work early in the morning, a place you´d rather avoid, in rotten weather, when you are a bit hung over from the night before ...
Allen reinforces my opinion that motorcycles are NOT a form of transport, they are much, much more than that.
I´ve joined the ranks of elderly gentlemen on scooters, and what do you know ? For all of my decades of experience, I´m once again, a small fish in a big pool.
Yes, let's take a stock widowmaker, pop off to the shed and add another cylinder. And with that calm and soothing voice, it all sounds so reasonable...oooh some birds, a hedgehog, may as well have some fruitcake, a therapeutic polish...right then, off we go winding out satan's express elevator to redline on a cart path. The serenity is surreal. Am I the only one who finds the measured tones of this endeavour to be irresistibly insane? I lack the language to sufficiently pay the compliment which is due. Well done, sir. Well done.
I just love how restless and resentful it sounds on the overrun. It's as if it's grumbling about having its slides down, just begging to have them lifted high so it can scream like a banshee all the way to the redline.
What a motor!
Yeah, I'm sure that's what it was thinking.
@@jerrytee2688 Thank you for your constructive comment!
@@buggs9950 You're welcome brother.
A poetic analysis.
If that bike could speak it would be saying "Come see if you can master ME".Your spot on Buggs with your comments and machines like this which are an unknown quantity demand respect.I would love a go on it though having experienced big strikers back in the day.
It’s Sunday. It’s Alan. It’s just perfect 👌
We're well pleased with that :)
I had 2 Yamaha RD 400s when I was younger, loved the way they rode, and the smell of two stroke still has a place in my heart ❤.
No words Alan! Your channel is an absolute inspiration for anybody who'd love to push their skills to the next level. Just amazing stuff and thank you taking the time to create these and share with the world.
I love the way you describe the process of removing battery terminals in the same manner as describing how to add an extra cylinder... as if these two things are on the same level, in your world they probably are.
Great observation . Uncle Allen can jump off a cliff start falling then build a Glider out of the wooden matches he's been carrying in his pocket . And start soaring .
I changed my oil and took of the skirt to clean it the other day .
Ha! I could cope with changing the battery anyway!
Possibly the most therapeutic channel to date on TH-cam
Thanks Allen 😍
thanks
16:45 when you hear that ning ning ning coming off the throttle and it's really clean sounding, that's a happy two stroke engine.
With today's synthetic 2 stroke oil, these engines could last much longer then the past with far less spark plug fouling.
I applaud Allen for his amazing work.
A one of a kind 1000 cc two stroke Kawasaki motorcycle.
That sound is amazing.
Built and maintained by a quiet, brilliant and classy man.
His wife is a heck of a cook too.
That fruitcake looked amazing.
World renowned motorcycle engine re-designer, customizer and restorer, Allen Millyard. And he's quite good with animals too.
Somehow strange grin appears in my face everytime i hear 2-stroke engine roaring.
Huge thanks for saving my day.
That's why I can't give away my old 250ccm 2stroke. Every now and then you need a ride with such a machine.
@@Pizzaesser It is a priviledge, not a need.
all you need is soft and its tasteses lovely.
but, 1000 cc kickstart bambi just danses, when gentleman asks. Also pretty nice.
Allen makes one-off motorcycle masterpieces yet isn't scared of giving them a bit of stick either, what a champion!
Allen is trully genuine magician, everything seems so easy when he does it, but infact its pretty hard and mind boggling work he's doing so effortlessly.
He deleted the part where the local Constables stormed the gate and threw a net over him! Great videos Alan.
A bit of a cooking show, a bit of bird watching….and a cracking home made 1000cc two stroke road bike build and ride. The perfect combo of subjects for a TH-cam video. I wholeheartedly approve!
I'd rather own this bike than any modern one.
Agreed. Sadly, about the only thing you can buy today is a noisy tank like a Harley, or a "crotch rocket." I really miss the bikes from the 70s.
I fn luv this guy and his builds but I really would love to see that engine in a more modern frame.
@@bobw222 Kawasaki Z900 RS / RS Cafe, Yamaha XSR 700 / XSR 900, Triumph Street Twin, Triumph Bonneville, Honda CB1100 / CB1300 RS... among others. I do share the sentiment to some extent, but there are still bikes out there for almost every taste.
@@mhtate3626 I'm thinking in the area of 500CC or less, probably 250-350CC. I'm not much for long cruising.
Me too..
To sum up Allen:
"I just built it myself. It worked perfect"
Was well pleased with that 👌
I love that sound of a huge one liter/4cyl. crackling 2 stroke engine! A one of a kind monster!
It's been a long 50 years since I heard my triple Kawi revving. And for a moment there listening to your video with my eyes closed, for a brief moment I was a young man again with the sun on my face and nary a worry in the world on my triple. And who says time travel isn't possible?
Brilliant Allen. It’s what motorbikes should sound like
Wonderful racket!
what a beautiful thing. and you sir, are a national treasure.
A terrific video Allen.
In the 1970s and 80s, I lived in Gunnedah NSW, Australia, and was a member of the motorcycle club there.
A fellow club member, Mal Mapperson (with passenger Rusty Scrivenor) had won the 1966 Australian Dirt track Championship, and finished second in the U/L sidecar race at Bathurst (on his highly tuned Triumph).
Following a bad back injury when felling trees, Mal mostly focused on sidecar road racing during the 1970s, and around 1975 he was racing an H2 powered sidecar with considerable success. Towards the end of the 70s, he did what you have done here - he added an extra cylinder. He raced the Kawasaki 1000 with considerable success, both in road racing and in speedway racing.
The bike is now in the National Motor-Racing Museum in Bathurst. Bike number 92.
You can imagine the neighbour , " When Allen put that bike in the garage it had three cylinders and it's now just come out with four! I need a lie down!"
Using my hacksaw. The new engineering term that will hurt the feelings of most newly qualified University graduates. Great.
it just looks '' factory '' its so correct in every way , a great job.
Sweet I remember that old sound brings back memories of my younger days thanks Dr Frankenstein of motorcycle building cheers sir
As an engineering teacher I am very impressed with the innovative techniques and attention to detail in these modifications. I enjoy them very much. The bad news is that I owned an original 1972 H2 Blue Meanie as they were nicknamed. They earned their reputation as one one the most dangerous motorcycles ever made. They did one thing very well and that was go fast in a straight line and that was it. They accelerated so fast, the back wheel quickly ran under the front causing an almost uncontrollable wheelie. They had poor stopping power and a weak frame that flexed under hard cornering. I can't imagine what this thing would be like with another 50 HP.
Thats just what everyone needs 🤠🤟
A beautifully relaxing way to spend a moment with a cup of tea and my wife's own plain scones. Life doesn't get any better!
I used to drag race the H2 in the 70s , it's still the most exciting bike ever , I sent my engine to California from Canada and had them build an ultra cobra engine , ran high nines in the quarter , 149 hp !
Awesome
I had a little 350 triple Kawasaki. Great fun.
Pure engineering pornography. I'm sorry but this is simply beautiful. The way you just say "I did this, then I did that" for us mere mortals, what you do is nothing short of miraculous.
My first bike was the KH400 triple, and to see you build something even more amazing truly touches my heart.
And all work completed with a single F or C uttered ...remarkable!
I love the 1/2 second clip from the road edge - "shuuum!"
amazing how chill he is about what is a remarkable bit of engineering
The bit I love every time is about cutting the crank-case in half with the trusty hacksaw. I can only imagine the mechanical carnage that would ensue if I tried that!
This guys a genius. In the absolute true sense of the word. He's almost a bloody alchemist. He just.... knows..
What a beautiful sound. Reminds me of my teenage years
5am NZ time and what a start to the day!.Morning coffee and watching Allen.
First time I have seen this site. Really brings back memories of years ago when I was young and single I had an S2, when I was still in school, then bought a KH 500 used the cruise Lloydminster AB killing everything in town. Then did some mod stock racing on weekends. Would love to see these up close. He truly is a mechanical wizard.
The bike is a beast, but I enjoyed the fact that he took the time to enjoy the birds, and had some tea and cake, before letting her scream...
Never change this homemade style of making these videos. As you would say, just perfect.
Allen, you never fail to entertain - A vintage 2 stroke, cookery and nature programme all in one.
That 1000cc 4 cyl Kawasaki sounds better than anything I have ever heard - absolutely gorgeous.
As for that cake, it looks heavenly and I could almost taste it from here.
Well done yet again sir.
A symphony of pistons.. a 2 stroke dream, even in the overrun... what fun.. put a smile on my dial..!
Total Mad Max ride, obnoxiously LOUD and scary fast, love it!
Absolutely love your work, thanks for keeping the bikes alive and making them even better
Beautiful job Allen, insane sound for that 4 cylinders widow maker lol
Awesome video. Your talent and work shows in every bike you touch! I love the 13 different camera angles and not one shows another camera mounted anywhere! Your attention to detail is fully appreciated here.
All static shots are filmed on my iPhone and moving shots on a gopro
Can't believe you were able to do this, as if not much more than a hacksaw and fingernail file were needed to pull off this mind-boggling conversion. Speechless. Made me recall my 1971 CB-750, though, my first bike, one I enjoyed 100%.
Been looking forward to this video, just can't beat a sweet running 2 stroke :0)
Sounds of which may render the sensible insane.
This is pure gold and Mr Millyard is a national treasure.
Absolutely stunning, never thought I would see a 4 cylinder 2-stroke engine. Sounds equally as nice
After the first five minutes I was hypnotized and after you started the engine I was like „WHAT IS THIS?“ this engine is screaming like days of thunder 🤘🤩❤️ Respect Sir 🫡👏👏👏
There's something very therapeutic when watching one of Allen's videos. A perfect combination of calm mechanics, cake, tea, wildlife, two stroke sounds and an English summer ride.
Cheers Allen from a Yorkshireman down under. Keep them coming.
Impromptu baking lesson as well Allen, very impressive.
Memories, Oh, the memories.... '67-'70, Yokota AB, Japan, and me with a brand new Kawasaki Mach III, 500 cc triple. On one of my tours, heading for Kyushu, I found myself racing the bullet train for a few miles in southern Honshu..... prior to the Mach III, had a Kawasaki A1SS 2-stroke, rotary valve 250 cc, and then bought a Kawasaki 650 cc W1SS. I eventually ended up with the Honda 750/4 and took it and a Kawasaki F7(?) 175 cc with Hata forks back to the States..... Oh, those were good times. Many bikes later and probably my final ride, I now ride my Suzuki S-70 650cc Savage. Thanks for the memories!
I had an S3 400 in the 80s. I love the way triple & now quad 2 strokes sound. Keep on building those crazy engines. It takes a while to get through your videos but the soothing way you walk us through your builds encourages patients. 👍🏼👍🏼👍🏼
The S3 400 was the best of the Kawasaki triples as far as being an actual motorcycle that you can use as regular transportation. They handle the best and overall are just the best designed triple Kawasaki made. And they're still quick bikes.
Fabulous! I used to own and love an S1 250 as a spotty teenager in the late 70s - and I'm now so nostalgic for that triple ownership experience. Your H2-and-a-bit is a true dream machine. A++ - thank you.
That was so therapeutic and calming to watch the first part and then the riding section made me realise I need a stroker! Thanks Allen for bringing a smile to so many peoples faces!
These videos are so relaxing and interesting for me to watch. It's funny to me how a man so civilized and create a machine so wicked. Love it!!!
Hi Alan, a lifetime ago I grafted two RD400 bottom ends together keeping the right hand engine complete with an extended driven shaft to get the engine sprocket to line up with the rear one and used two pairs of 350LC power valve top ends jacked up to match the stroke so 800cc power valve 😁 that went into an XS650 frame and tarted up the look like Mr Roberts yam the plew the Harley's away on the dirt tracks. God knows where it is or if it is still in one piece.
Man caves are such wonderful places and I love cake as well 😂. Ian.
Love the 4 cylinder 2-stroke H2 1000!! Great day for a quick jaunt down the road on that rolling masterpiece. Long live the "smokers"!
Keep the cool videos coming, Allen!
I enjoy this immensely. The 4-cylinder 2-stroke has beautiful proportions, amazing sound, and the performance to match. What a treat in aesthetics!!!
Incredible. I fondly remember the 70s Kawasakis, so distinctive.
I really enjoyed learning about the float bowl leak issue & the fix. I also valued the overflow tube removal tip. Thank you, Mr Millyard!
That 2 stroke is running amazingly smooth perfectly in tune especially on the overrun just burbling nicely.
Genius project !!!
Ikr
I'm out of superlatives for this genius' creation's. I'm so amazed🙏👍
Now Thats something you dont see or hear very often, if ever! Wow! what a piece of work and what a sound!
You are simple Genius Allen!!! Greetings from Poland.
Music to my ears. Allen, your filming is as good as your engineering. I feel like I’m riding with you as I watch. Thank you for another lovely video.
That is 1 extremely impressive peace of machine and a very clever genuine man
The sound of those four cylinders, and chambers….man…man…man.!!!! Nothing like it.
What's life without motorcycles and cakes! I enjoyed every minute and I was mesmerized by the sound. Thank you :)
I got some JIS screwdrivers they are just perfect for Japanese screws
I love it when he says 'and it works perfect'.....🥰
That’s the nicest sounding motorcycle I’ve ever heard in the world. It’s much better as a four-cylinder super rare probably only one only he can do what he can do. He is amazing.
You never cease to amaze me Allen, beautiful bike with a beautiful sound, the colour is stunning. Thanks for taking us along atb: Russ 👍🏼🏍
that is one incredible sound,i love it
Your channel is just great, I really enjoy looking at your videos.
Reminds me of blasting my KH250 triple around country lanes in Dorset as a youngster in the 70's! Cracking stuff
Always a pleasure watching your videos. You make the most difficult of tasks appear so simple and logical. Awesome.
That sounds bloomin perfect
Hello from Texas. That is absolutely Amazing. I’ve never heard of someone making a 3 Cylinder to a Four Cylinder on any Motorcycle. Plus making the Expansion Chambers yourself. What a incredible Job, it sounds Incredible, Runs Incredible, all I can say is Wow. Just kinda stumbled on to your Channel and glad I did. Unbelievable what you accomplished. Low Bow to you. Thanks for the Video just Subscribed and can’t way to see more.👍👍❤️😁
This is one of the Coolest things I’ve Ever Seen or Heard…!🤯🔥
You're a genius Allen, it's always interesting watching you maintain and adapt these fantastic classics.
Your calm and coherent demeanour and eye for detail, makes for quality workmanship, and you always make time for a cake or two and include animals in your videos. My favourite Motorcycles are the Japanese ones from about 1969 to 1983. It's the classics I enjoy seeing the most. There are so many great 2-Stroke & 4-stroke motorcycles from that era and if I was to pick a favourite it would be a 1975 Honda CB750F Super Sport in Candy Sapphire Blue or Sunburst Orange. It might have been called Sunrise Orange but thanks for keeping some of those fantastic bikes alive and in great working order. All the best Allen.
