A friend on mine saw it for sale at a dealer auction a few years ago. He said I would really like it so I asked him to bid on it for me. He bid above my maximum, but I'm glad he did. I had no idea if it ran and did not know about Allen Millyard at the time. I contacted Allen and he gave me tuning specifications that were spot on. After a month of minor restoration work I had it running nicely. My hat is off to him. Pure genius.
I would love to know what the bike cost. I have always wanted an Allen Millyard creation but I am just looking for confirmation that I could never afford one.
Allen Millyard is a genius who creates functional art with his bikes! I know he means for them to be ridden but i'd keep the miles low on that priceless 1250 widow maker! You are very lucky to stumble on to it!
He is a genius, and just casualy sticks a few extra cylinders on just about anything. If you like a mad bloke in a shed, try Colin Furze. Ordinary plumber that has made a hover bike, underground bunker, 107mph dodgem car and too many other things to mention. He even made a 2 stroke bedside lamp for the real man, saying that real men find electric lights too soft and easy. Everything Allen Millyard makes has no real practical purpose, he just makes any bike much more desireable. Do we want one of his creations? Silly question, we all want one.
@@MrDickBills Colin sure has a way of making the maddest of ideas work! His turbine-powered barbeque is my personal favorite... However, he still has a long way to go before equalling the brilliantly mad, shed-dwelling, artistic petrolhead genius that is Allen Millyard...
These two shouldn’t be mentioned in the same comment as one is still figuring out how to land on the moon and the other explored GN-z11 over a decade ago.
@@henkverzeijl1525 for me the jet powered shopping bike was Colin's maddest creation. That was a truly dangerous vehicle which he demonstrated wearing only his safety tie as added protection. His wall of death made from about 100 thousand freight pallets is up there too. It ended with the world's biggest bonfire.
I bought a 750H2 Mach IV new in late '71. I still got it in mint condition, 12,678 miles today. At no time in the intervening 52 years have I ever once wished it had more cylinders.
Had one as well in the mid 70’s. Never did I wish for more power, it had plenty at the crack of the throttle. Handling was a different story. Nasty habit of wobbling the front end at speeds over 70-80 mph. Added a nice dampener and problem mostly went away. Riders these days will not experience the power band the two strokes had back then. Plenty of torque without having to rev the hell out of it. Had a friend that had the 500. He trimmed the back skirt of the pistons up to move the power band up in the rpm range. Bike had no power until around 5000 rpm, but when it hit 5 you better be hanging on tight. Thing was dangerous though with no low rpm power on the street. Bought a CBR900R in 1995 and it’s power band reminded me of my buddy’s 500 to some extent. The CBR was a way better machine in terms of overall handling. 20 years of R & D really pays off.
Extrapolating the original H2 HP with the displacement ratio gives 123HP. Hitting this figure shows that he didn't just add 2 cyls for the show, it actually performs as if the engine came out of the factory like that. Allen's builds have always amazed me and his recent "how to" series is jsut unbelievable. Hacksaw, tin snips.. incredible.
Yes, I think one of Allen's goals is to make every bike look and perform "factory". I too love his "how to" videos. Very inspiring! Thanks for watching -Kirb
He uses a lot more than a hack saw and tin snips. If you watch any of his videos, you'll see there is work on a milling machine to get the engine halves to mate properly.
Yeah when Allen builds these crazy bikes starting with a factory engine, he builds it up like they the manufacturer themselves would've, so in this case, no extra porting, no higher potential expansion chambers, no crazy carb work...he wants it exactly how it "would've" been made.... trust me, I could only imagine what Allen could produce if he actually built this 5cyl 2t into something more monstrous than it already is 😅 Next I want to see his completely hand built RC374 on a Dyno.... I love 2t's....adore them...but I'd love to see what that RC makes 👌
Walter Kaaden the race engine designer for MZ worked with little more equipment than Allen. Kaaden. Iron curtain East Germany was starved of equipment by the Russians. He struggled to get decent ball bearings. Kaaden understood gas shockwaves and invented the exhaust expansion chamber and the piston boost port. During the 1950s he was getting more than 30bhp from 125cc. Nobody knew ho he got so much power. Then his race Rider Karl Degner defected and took a bike with him. Suzuki bought his services and the bike sort of came along too.
Thanks for posting this. A great tribute to the genius of Millyard. I had the honour of meeting and chatting with him at a bike show last year. Lovely chap, super friendly and completely approachable.
Great to see one of M. Millyard's Bike in the real world! I could easily imagine clutch slip with 120 HP feeding it! Thanks for sharing, and for looking after this creation!
Great simple solution to the lack of electrical power, going to LED lighting rather than trying to find an upgrade to the whole charging system. Allan Millyard, your creations are so well crafted. Genious!
I remember this H2 PILOT up at New England Dragway back in the early 70's , He hit 2nd or 3rd gear at about 70 mph and that H2 stood straight up on the back wheel !!!! He brought it back down some how but My stomach was in My throat just watching. I went out and bought a nice 1970 Triumph 500 Daytona because I hoped to live until My 60's and still be riding. Still riding now but had the Z1 which was tame compared to the H2 , that was one wild machine to be very respected and not for beginners. Thanks for the video, those 2 strokes were great machines from a bygone era.
We had new SS Honda 750's when the other roomie bought an H2 750. It was just a rocket and he rode it around on the back wheel with his girlfriend on the back! I jumped on a H1 500 with pipes and it scared the crap out of me, knew I would get hurt if I bought it.
@@rondyechannel1399 Good Decision, My Z1 900 was fast enough but that H2 was a monster when you hit the powerband. You could hear that 2 stroke triple a half mile away ! The SS Honda 750 was an excellent bike, lots of power and plenty fast. I'm working on an old 72 Honda CB750 right now and you can still get parts for them. Something to cruise around town with. Take care, Steve C.
@@cantelya53 When those Z1 900's came out, the Honda 750 got an upgrade, (my roommate owned a Honda bike dealership), we bored out the 750 liners and pressed in liners for an old flat head Ford, then bored and trimmed those to fit Honda 350 pistons, then bought a road race cam from Poweroll, added smooth bore Mikuni carbs, and a Kerker 4 to 1 header. It got horrible mileage but would stand straight up at 70 mph! Stock would not even lift the tire. Today at 69 I just finished a restore on a '77 naked GL1000. Well changed a few things like bars etc. I'm always eyeing garage/estate sales for those old Kawi's though, Z1's or triples. Don't care for most new bikes.
@@rondye9398 Hi Ron, your speaking My language. The 70,s bikes were the best in My opinion to. They have some great tech nowadays but no good all around bikes like back then. To specialized now and you end up changing everything, seats, bars, pipes, etc and they still don't have the flavor of the old UJM,s. I like the idea of going to Mikuni's and a Kerker for that Honda. A Kerker in the 70's was about $200-$300 now about $1000. The Mikuni' probably big money to. I like the Mikuni's better than the Honda Keihnin carbs (spelling ?) but might go to that 4 into 2 carb setup I have been reading about. I also had a GL1000 Honda with the old Vetter fairing and hard bags, good bike but down on power, needed a rebuild. I think some of the dealers had a 803 or 825 kit for the 750 way back when. I don't have the know how to shave flat head ford liners and install 350 pistons or cam work just looking to put My 72 CB750 back together basically stock and ride. Not looking for a show bike. Good luck with the GL1000 and your other bikes Ron. Take care, Steve C.
What a great video. Allen Millyard stuff doesn't just look fully sorted, then! I didn't know he actually ever sold any of his creations, so congrats on buying one - and showing us what it's like!
Yes, you could hear the revs jumping probably when you got that step increase in torque on the graph. Wondered if it was wheelspin but more likely the poor clutch. Sounds fantastic.
I feel very lucky too. That's why I do these videos to share Allen's talent! Thanks for watching!! Also, thank to Curt Jordan for the careful dyno work.
Thank you Allen for your incredible creations! Love watching and listening to his videos. Awesome that this machine made it across the pond. What beautiful 2 stroke music!
Old two strokes have a narrow power band. Curt was confirming the tachometer was synced with the dyno with the thumbs up. The power comes on suddenly at about 5000 RPM and peaks at 7500. No rev-limiters in those days. Allen built a custom 5 points system just for this bike which can be seen in the first video: th-cam.com/video/v62pCre4Lfk/w-d-xo.html Cheers, Kirby
As a life long 2 stroke builder and racer, the mention of 927 made me say, "finally someone who knows their shit!" I would encourage these dudes to slap on some expansion chambers and some porting/polishing and perhaps indulge into some lectron carbs, or maybe a fuel infection setup and witness some extreme performance gains! I cant say enough about 927. I like mine about 40-42 to 1 most days.. Stabilize when cold. Good shit.
@@SKRAPNOID Yes, nothing quite like the castor aroma! Reminds me of Klotz we used for premix back in the 1970's when I raced a Suzuki RM125. Such a rush with 40 made bees on the starting line. Cheers, -Kirb
Back in the late 70's early 80's a mate and me helped assemble a rolling road machine for a lad's Norton shop , Roger the shop owner gave my mate the opportunity to put his 850 Commando on it 118 mph shredded the back tyre a brand new Avon what a racket , got it replaced but didn't tell them how it happened .
I was going to say that it sounded like you were getting some clutch slippage as it started to get into the meat of the power band. My old H2 had that problem which I fixed at the time with a barnett clutch. Gorgeous bike with an awesome sound. BTW I love the shot of the operator with his hair blown back. Reminded me of the old Memorex advertisement from the '80s
Yes, Curt does look like the Memorex guy blasting in the wind. The clutch probably does slip a bit on the dyno since it was designed for 75HP, not 120. Does not slip when I ride it, but I never get it going that fast. Thanks for watching!
I clipped that ad and put it in a round frame. I could turn it according to my mood, either up like a jetliner taking off or downward in pure terror! (Usually during finals week).
great Job man, and the sound is so amazing wow, yes the small diameter off the clutch can make every time problems with to hard working torque and power. Great Video, greetings from an old 2stroke driver AD (RD350YPVS31K) from Germany.
I borrowed a KH500 for a short trip. Howling round the first sweeping bend the wobble was terrifying. If I had had a knitting needle in each hand I would have knitted a jumper. The frame felt like it was made of rubber.
I had a 72 500. Tapered roller bearings in the steering head and caged needle bearings in the swing arm, fresh tires with an aligment solved 90% of the problem. Also I had a Barnett extra plate racing clutch. Wish I still had it. Thank you for sharing this with us, it sounds awesome out on the street.
So glad this brought back good memories for you. Curt warned me that dyno tests on classic bikes rarely go well and usually blow something up. Fortunately, this one went well and some unique experiences are here to share!
The artistry or shall I say wizardry of the mechanics of this bike as well as the sculpture of it's lines. An Apex. I'm only seconds into this. I need watch the first.
My 73 h2 king cobra made 120hp on pump premium. No extra cylinders required. Wish I could load up a pic here. Nice interesting machine you got there man.
Love the pipes. The shape and angle are absolutely spot on. Good eye. They're so much part of the look of this bike and much better than the factory triples by some margin. Terrific stuff
I was not expecting nearly that much horsepower. A stock 750 triple is about 59-60 rear wheel horsepower. Did Allen port the cylinders? They have to be worked. It looks like it even has the stock 30 mm carbs instead of 34's or bigger for more power. Fantastic performance. It must be a real rush to ride and is a one of a kind conversation piece. Allen's work is incredible. I had a blue '72 and a purple '73 way back. Wish I still had one. Thanks for sharing!
I think you are right on the stock numbers. Curt said that a stock H2 750 with pipes and pod filters should do about 70HP at the rear wheel. This bike was not ported, but it does have oversize pistons that actually make it a 1300cc. Curt thought a little fine tuning and new clutch would add even more power!
I started on Kawasakis in 1969 and my first triple from 1973 to 2015 so you know I love this bike! Now I know 120 horsepower might get you a solid 160 mph on a bike of this weight but frankly dyno speeds are usually better than real world with wind and a rider on them. I did hear the clutch slip a bit too. I've run bikes at Bonneville for 10 years anything from 55 to 201 horsepower I do believe your 120 horsepower is enough for 160 mph at Bonneville with some aerodynamics. This past August I got 151 mph out of 100 horsepower with some aerodynamics. If you ever would like to run this great bike at Bonneville I'd be happy to ride it...it would make jaws drop out there. I have some videos on some my runs on my website.
I think you are correct. 160 mph would be on the dyno, not on the track. Still a fun number to reach on the bench. It would also have stability and handling issues too so I won't be trying it.
Still cant believe that bike turned up at NPA, I talked to Alan about before the auction started but I had my cut off, great to see Curts working on it now, Bloke knows his stuff
What a fine job made by Mr. Millyard. I will love to see/hear Mr. Guy Martin from Lincolnshire UK drive this artwork on Isle of Man. The sound of the engine is something I will never forget; in my opinion, it is a little like the first time hearing a Porsche 917. Yes of course it doesn’t sound the same, but in both cases, it sounds like pure racing.
Man, I cant wait to start on my GT380 project! Good call on the LED lights! I've switched all my bikes over for the same reason....don't really care about the difference in light, but the power savings so the rest of the electrical system has more voltage, makes a big difference.
Wow, I got side tracked here after watching Allen's latest video on the 73 H2 1000 (4 Cylinder) he built. I had no idea he built a 5 Cyl. as well 😲 Very nice Car and collection of Bikes Sir.👍 (NOT a cut) but I laughed when you mentioned the MPHs because all that's good for (on a dyno) is seeing what the gearing is capable of, not how fast the bike will actually go on the street/track. My first "Real Bike" was a 72 H2 so I can say for sure that you wouldn't want to try going over 120mph (without chassis upgrades). My 'daily driver' H2 with cylinder porting, Denco heads and chambers ran 11.70s at 110mph 1/4 mile (that was fast back in the 1975) and I'm not kidding when I say it handled SCARY BAD if/when I tried going over 120mph 😱💀 Since then I have had a Z1, three 78 Z1R and a ZRX 1200R Turbo = I have always💖Kawasaki...
You're right, my standard H2 and H1's get nervous around 90. Triple with a ripple indeed. The 160 is only just potential energy but fun on the dyno. Don't think I would try it again. Thanks for watching and your thoughts!
Is it just me who's a bit uncomfortable that the creation of a genius is being tested? I'm pretty sure Allen builds these bikes to ride and enjoy and I bet he doesn't do anything as crass as dyno testing. Sounds amazing at the end zone of the video 😎
Why shouldn’t it be tested it is not some historical artifact, it is a motorcycle built by a brilliant engineer and it should be able to withstand a Dyno run.
Allen Millyard is a genius engineer. This Kwaka is the business... 5 pots, 120 hp and 160 mph! Can you imagine the acceleration on a wide open throttle? You'd have to hang on for dear life.
These guys are just the groupies. Allen Millyard is the ROCKSTAR. He builds the best downhill mountain bike on the planet as well. A viper v10 bike... And many many more awesome machines. Google the man. A pure genius
Jesus guys I can't believe that, 98 foot pounds of torque and 160 plus miles an hour with 121 HP, my gosh that is extremely impressive 😲! Alan Millyard you truly are a mad genius brother! I wish to God I lived in England and became your neighbor! I swear I would pay you up the ass to build me a motor like that! Alan you are brilliantly genius man!!! Truly genius!!!
Mr Millyard has taken a Widow Maker and transformed it into a WidowandOrphan Maker !!! See what a hacksaw and flat file can do ? Respect. Trinidad & Tobago.
Sounded great. Very brave to put that one of a kind engine on a dyno. I spoke to Allen at the last classic bike show and he was amazed at the number who viewed your last vid. He is currently building a super 6 Kawasaki 4 stroke, which I'm sure will be amazing. Best regards
Yes, I've only spoken to Allen via Facebook, he was very helpful with tuning and timing (the bike had not run for many years). Curt Jordan (Dyno guy) said it was one of the best one-off tests he has ever done. A tribute to Allen's solid engineering skills. I'm pleased to share this amazing bike with so many!
@@cramersclassics Allen is an amazing talent and I'm privileged to live reasonably close to him and attend many of the same events as he does. Last year on my channel I filmed him starting some of his bikes at our British Motorcycle Museum and was amazed at the interest and views on that vid. Thanks for the reply, take care and best regards from England.
I love it!!!! Also Allen gets a clip of vid sent to him and can tell it is slipping the clutch hahaha.....what a dude! Jordan engineer is an engineering god in his own right yet Allen can hear the thing is just a little bit off. That engine with 98 pounds of torque must be a beautiful thing to ride in everyday situations. Rolling on in a higher gear is a great way to ride on the road rather than a narrow powerband. 5 cylinders sounds absolutely stunning, shows what manufacturers should have been making.
Good grief, what a sound! Really sounding like Formula 1 great M. Schumacher in his best days. Thanks a lot for making recording editing uploading and sharing. Best regards luck and health to all involved people and engines! :-) ;-)

Sometimes selling a creation finances the next.
He discreetly sells them, The Barber Motorcycle Museum has bought some.
Millyard is nuts. But some brilliant ideas. A 5 cylinder Kwacker 1250 stroker. Bonkerstastic man.
What a sweet bike. Curt Jordan sure knows his stuff, when it comes to high performance. Very impressive video..⭐️⭐️⭐️⭐️⭐️
Just love the sound of a multi cylinder two stroke or any two stroke really.
Wow, I would never have imagined the ignition system drawing so much current. Bike sounds great and looks beautiful
Yes, you could hear the revs jumping probably when you got that step increase in torque on the graph. Wondered if it was wheelspin but more likely the poor clutch.
Sounds fantastic.
Check out Allen's latest 6 cyl Kawasaki Z1 1400 sheer genius.
Thank you for showing this. Alan is a genius. Nice guy too.
You're right Allen seems to be getting the attention he deserves with this creative mind and amazing skills!
All done in his 13 x7 garage and the kitchen oven and floor.And his bikes are in the best museums in the world..genuis
You sir are a very fortunate man owning a Millyard creation - never seen any custom bike before or since that comes close to what he does, cheers.
I feel very lucky too. That's why I do these videos to share Allen's talent! Thanks for watching!! Also, thank to Curt Jordan for the careful dyno work.
The first time it revved out, I had the hair on my neck standing up! HOW GOOD DOES THAT SOUND!!
What an amazing achievement. 👌🏽
This thing sounds like an F1 racer and *I LOVE IT!*
Thank you Allen for your incredible creations! Love watching and listening to his videos. Awesome that this machine made it across the pond. What beautiful 2 stroke music!
Sound at the end is heaven
Alan is THE English Madman in the Classic sense. Awesome.
I'll tell you this the video quality here and in the above drone shot is like 4K ultra. Awesome
That thing sounds amazing. Millyard is one of those slightly mad geniuses.
Thank you for posting this beauty! Allen Millyard has a great, God given talent and much respect to him for using it well.
This engine is simply a masterpiece! Congrats to Millyard!
Oh how I miss the sound of 2 stroke superbikes! Thanks for posting this video! Absolutely incredible!
BEAUTIFUL BIKE!!! Even more impressive is the man who created it with such expert craftsmanship. Thanks for sharing it with everybody here on TH-cam.
Insane amounts of power for that awesome beast, I hope you have many miles of smiles on that beast
Old two strokes have a narrow power band. Curt was confirming the tachometer was synced with the dyno with the thumbs up. The power comes on suddenly at about 5000 RPM and peaks at 7500. No rev-limiters in those days. Allen built a custom 5 points system just for this bike which can be seen in the first video:

As a life long 2 stroke builder and racer, the mention of 927 made me say, "finally someone who knows their shit!" I would encourage these dudes to slap on some expansion chambers and some porting/polishing and perhaps indulge into some lectron carbs, or maybe a fuel infection setup and witness some extreme performance gains! I cant say enough about 927. I like mine about 40-42 to 1 most days.. Stabilize when cold. Good shit.
@@SKRAPNOID Yes, nothing quite like the castor aroma! Reminds me of Klotz we used for premix back in the 1970's when I raced a Suzuki RM125. Such a rush with 40 made bees on the starting line. Cheers, -Kirb
I love Allen’s TH-cam channel his bikes are amazing. Thanks for showing us your bike
Took a "Widow Maker" and turned it into a Crowd Pleaser . Well done. I'm only jealous.
yep those vintage 2 strokes were a lot of fun to ride. I imagine dinosaurs were fun to ride too.
Millyard is an artist and the sound is just amazing
Very nice Mr.
And Kurt Jordon is very Good guy, he gave parts and his knowledge in Santa Ana Ca. for all my Z1 900s a
Sounds like an 80s formula one car on the gas to me.
I could watch this stuff all day.
Me too! Thanks for watching. - Kirb
British bike engineering at its best........Allen Milliyard
More like Britainese or Japanish engineering.
Alan does build a great engine,it ticks over and revs beautifully, and look at those power curves,its shows the quality of the engineering
I take my hat off to people like you, pure genius. Awesome sight.
Back in the late 70's early 80's a mate and me helped assemble a rolling road machine for a lad's Norton shop , Roger the shop owner gave my mate the opportunity to put his 850 Commando on it 118 mph shredded the back tyre a brand new Avon what a racket , got it replaced but didn't tell them how it happened .
I was going to say that it sounded like you were getting some clutch slippage as it started to get into the meat of the power band. My old H2 had that problem which I fixed at the time with a barnett clutch. Gorgeous bike with an awesome sound.
BTW I love the shot of the operator with his hair blown back. Reminded me of the old Memorex advertisement from the '80s
Yes, Curt does look like the Memorex guy blasting in the wind. The clutch probably does slip a bit on the dyno since it was designed for 75HP, not 120. Does not slip when I ride it, but I never get it going that fast. Thanks for watching!
I clipped that ad and put it in a round frame. I could turn it according to my mood, either up like a jetliner taking off or downward in pure terror! (Usually during finals week).
great Job man, and the sound is so amazing wow, yes the small diameter off the clutch can make every time problems with to hard working torque and power. Great Video, greetings from an old 2stroke driver AD (RD350YPVS31K) from Germany.
Excellent video! Everything I wanted to know about this incredible bike. Thanks!
I borrowed a KH500 for a short trip. Howling round the first sweeping bend the wobble was terrifying. If I had had a knitting needle in each hand I would have knitted a jumper. The frame felt like it was made of rubber.
The most impressive part is it was built in his shed.
with a hacksaw.....haha
I had a 72 500. Tapered roller bearings in the steering head and caged needle bearings in the swing arm, fresh tires with an aligment solved 90% of the problem.
Also I had a Barnett extra plate racing clutch.
Wish I still had it.
Thank you for sharing this with us, it sounds awesome out on the street.
So glad this brought back good memories for you. Curt warned me that dyno tests on classic bikes rarely go well and usually blow something up. Fortunately, this one went well and some unique experiences are here to share!
The artistry or shall I say wizardry of the mechanics of this bike as well as the sculpture of it's lines.
An Apex. I'm only seconds into this.
I need watch the first.
Sir there r many bike builders but u r my favouret one, again thank u for all this beautyful videos n all this info, god bless u Sir.
I wonder what the original designers of the range Kawasaki triples think of Allen's modifications? I expect they are as thrilled as the rest of us.
No, they are horrified, as they should be.
@@NeverTalkToCops1 horrified!! I thought they would probably be rather impressed like everyone else.
There's a story of an exec from one of the Japanese m/bike companies seeing one of Alan's creations saying that is one we should have built
My 73 h2 king cobra made 120hp on pump premium. No extra cylinders required. Wish I could load up a pic here. Nice interesting machine you got there man.
Love the pipes. The shape and angle are absolutely spot on. Good eye. They're so much part of the look of this bike and much better than the factory triples by some margin. Terrific stuff
All the fab work was dome by Allen's skillful hand!
I was not expecting nearly that much horsepower. A stock 750 triple is about 59-60 rear wheel horsepower. Did Allen port the cylinders? They have to be worked. It looks like it even has the stock 30 mm carbs instead of 34's or bigger for more power. Fantastic performance. It must be a real rush to ride and is a one of a kind conversation piece. Allen's work is incredible. I had a blue '72 and a purple '73 way back. Wish I still had one. Thanks for sharing!
I think you are right on the stock numbers. Curt said that a stock H2 750 with pipes and pod filters should do about 70HP at the rear wheel.
This bike was not ported, but it does have oversize pistons that actually make it a 1300cc.
Curt thought a little fine tuning and new clutch would add even more power!
@@cramersclassics Thanks, the extra displacement really makes a difference. Enjoy that beautiful machine!
72's were 4" shorter
love it, I had the '74 H2 750, it was almost a widow maker with me but I survived it.
I started on Kawasakis in 1969 and my first triple from 1973 to 2015 so you know I love this bike! Now I know 120 horsepower might get you a solid 160 mph on a bike of this weight but frankly dyno speeds are usually better than real world with wind and a rider on them.
I did hear the clutch slip a bit too. I've run bikes at Bonneville for 10 years anything from 55 to 201 horsepower I do believe your 120 horsepower is enough for 160 mph at Bonneville with some aerodynamics.
This past August I got 151 mph out of 100 horsepower with some aerodynamics. If you ever would like to run this great bike at Bonneville I'd be happy to ride it...it would make jaws drop out there.
I have some videos on some my runs on my website.
I think you are correct. 160 mph would be on the dyno, not on the track. Still a fun number to reach on the bench. It would also have stability and handling issues too so I won't be trying it.
@@cramersclassicsI just got back from Bonneville Speed Week 2023 and unfortunately my trip ended in a helicopter flight off the salt.
Dang, hope you are ok! @@flatcapcaferacer
Still cant believe that bike turned up at NPA, I talked to Alan about before the auction started but I had my cut off, great to see Curts working on it now, Bloke knows his stuff
Allen was right, the clutch was clearly slipping @ 3:32. What a beautiful machine.
120 HP on an extended crankshaft is enough!! Great job!!
Kawasaki ruled the world with those 2 strokes.
Wow! You have a very nice drive way! I can smell the fresh asphalt from here!
beautiful bike!
Wow. So great of you to share this! You have new fans over here at How2wrench!
Geez I miss my Green 1974 H2 , we had many great miles of fun :) may she RIP :(
What a fine job made by Mr. Millyard.
I will love to see/hear Mr. Guy Martin from Lincolnshire UK drive this artwork on Isle of Man.
The sound of the engine is something I will never forget; in my opinion, it is a little like the first time hearing a Porsche 917.
Yes of course it doesn’t sound the same, but in both cases, it sounds like pure racing.
I watched the build video.
AMAZING
His bikes are so reliable and practical.
Man, I cant wait to start on my GT380 project!
Good call on the LED lights! I've switched all my bikes over for the same reason....don't really care about the difference in light, but the power savings so the rest of the electrical system has more voltage, makes a big difference.
Wow, I got side tracked here after watching Allen's latest video on the 73 H2 1000 (4 Cylinder) he built. I had no idea he built a 5 Cyl. as well 😲
Very nice Car and collection of Bikes Sir.👍
(NOT a cut) but I laughed when you mentioned the MPHs because all that's good for (on a dyno) is seeing what the gearing is capable of, not how fast the bike will actually go on the street/track. My first "Real Bike" was a 72 H2 so I can say for sure that you wouldn't want to try going over 120mph (without chassis upgrades). My 'daily driver' H2 with cylinder porting, Denco heads and chambers ran 11.70s at 110mph 1/4 mile (that was fast back in the 1975) and I'm not kidding when I say it handled SCARY BAD if/when I tried going over 120mph 😱💀 Since then I have had a Z1, three 78 Z1R and a ZRX 1200R Turbo = I have always💖Kawasaki...
You're right, my standard H2 and H1's get nervous around 90. Triple with a ripple indeed. The 160 is only just potential energy but fun on the dyno. Don't think I would try it again. Thanks for watching and your thoughts!
Is it just me who's a bit uncomfortable that the creation of a genius is being tested? I'm pretty sure Allen builds these bikes to ride and enjoy and I bet he doesn't do anything as crass as dyno testing. Sounds amazing at the end zone of the video 😎
It's a one-off bike. Who wouldn't want to know what it's capable of?
Why shouldn’t it be tested it is not some historical artifact, it is a motorcycle built by a brilliant engineer and it should be able to withstand a Dyno run.
Allen Millyard is a genius engineer. This Kwaka is the business... 5 pots, 120 hp and 160 mph! Can you imagine the acceleration on a wide open throttle? You'd have to hang on for dear life.
Even at half throttle you hang on! Thanks for watching. -Kirb
That thing, especially in the overhead shot at end, sounds exactly like a V-10 F1 car.
The F1 V10 would run to 15,000 rpm (maybe 18K) so it’s about 1/2 way there. :-)
@@Dave5843-d9m Try 22K...
Well inline-5 is half a V10 and being 2-stroke that means 7500 rpm is equivalent to a 4-stroke doing 15000 rpm
torque is amazing! great vid!
Very amazing bike!! You guys are like Rock Stars for motorcycles!
More like cover artists :) The real star is Allen Millyard in England, who built the bike.
These guys are just the groupies. Allen Millyard is the ROCKSTAR. He builds the best downhill mountain bike on the planet as well. A viper v10 bike... And many many more awesome machines. Google the man. A pure genius
that guy is sitting straight up .
i bet if he tucks in he would go faster !
@David Vance lol! Your answer in no way how correlated with the statement you replied too!
YEAH, LOL..
Jesus guys I can't believe that, 98 foot pounds of torque and 160 plus miles an hour with 121 HP, my gosh that is extremely impressive 😲! Alan Millyard you truly are a mad genius brother! I wish to God I lived in England and became your neighbor! I swear I would pay you up the ass to build me a motor like that! Alan you are brilliantly genius man!!! Truly genius!!!
What a beautiful bike . Alan millyard comes to mind 😀
Mr Millyard has taken a Widow Maker and transformed it into a WidowandOrphan Maker !!! See what a hacksaw and flat file can do ? Respect. Trinidad & Tobago.
Allen Millyard is simply amazing!
Sounded great. Very brave to put that one of a kind engine on a dyno. I spoke to Allen at the last classic bike show and he was amazed at the number who viewed your last vid. He is currently building a super 6 Kawasaki 4 stroke, which I'm sure will be amazing. Best regards
Yes, I've only spoken to Allen via Facebook, he was very helpful with tuning and timing (the bike had not run for many years). Curt Jordan (Dyno guy) said it was one of the best
one-off tests he has ever done. A tribute to Allen's solid engineering skills. I'm pleased to share this amazing bike with so many!
@@cramersclassics Allen is an amazing talent and I'm privileged to live reasonably close to him and attend many of the same events as he does. Last year on my channel I filmed him starting some of his bikes at our British Motorcycle Museum and was amazed at the interest and views on that vid. Thanks for the reply, take care and best regards from England.
I love it!!!! Also Allen gets a clip of vid sent to him and can tell it is slipping the clutch hahaha.....what a dude! Jordan engineer is an engineering god in his own right yet Allen can hear the thing is just a little bit off. That engine with 98 pounds of torque must be a beautiful thing to ride in everyday situations. Rolling on in a higher gear is a great way to ride on the road rather than a narrow powerband.
5 cylinders sounds absolutely stunning, shows what manufacturers should have been making.
What are sound guys, I am speechless
98 foot pound of torque and 121 hp @160 mph. Very impressive.
Good grief, what a sound! Really sounding like Formula 1 great M. Schumacher in his best days.
Thanks a lot for making recording editing uploading and sharing.
Best regards luck and health to all involved people and engines! :-) ;-)
