I've been following his channel for a long time, before this brand new channel, he build more than on this channel, unfortunately, his old channel were hacked 😢 He is truly my inspiration, never give up on everything 😊🎉👏🏻
My man must have some kind of engineering degree, he takes that already made and makes it much better. Nice job Mr Dan, can't wait to see what you build next. 🎉
The porting on the piston is set for max power at low RPM . Cause it’s a lawnmower engine not a high RPM engine. You might have to do work on the port timing. I see it smokes back through the carb which indicates it can’t blow out the exhaust gases to match the intake of air and fuel. Nonetheless still a very cool build bro!! Great skills you have!!👍
So cool! Afaik so far, there was only one production motorcycle ever built with a 2-stroke boxer, the IFA BK 350 from GDR. There was also a 4-cylinder double boxer by König (Germany) for racing, based on a boat engine.
Wonder if facing the intake side of the carb into the wind would help push all that fuel mixture in, a reed valve system wouldn't be a bad idea either way and could probably make a reed cage that just mounts to the intake before the carb so he wouldn't have completely redesign the entire system.
@@kcraig51 It is now a boxer with a common intake, so one piston is at TDC and one at BDC. As soon as the piston port opens to induct, the other piston crankcase is opened up to it. What ever pressure difference there is has to go somewhere and the only escape route is the carburettor inlet. It needs reed valves on each crankcase or two carbs.
Thank you Le Dan for your perfect work,making a little boxer from used Honda's parts like you do astound me 😮 as an engeneer you made this happening so easely...Your knowledges on material résistance are good and all on this pretty little bike have its place 😊❤ love it !
Two cylinders running off a common crankcase often has this exact problem: because of slight differences in rod length, ring height, etc while the intake, transfer and power strokes are synchronized and one cylinder robs power from the other. The most common way of preventing this is boosting the pressure in the crankcase which brings its own issues with blowing out crank seals.
Very interesting build. I suspect this would be very hard to tune, and never perform terribly well due to the shared case volume. Either way, very cool.
@@dennisyoung4631 Yeah, that might be one way, I've read through a couple of comments, made a reply on one besides this which I imagine you've probably came across or not.
might be able to make it a little more efficient if you put a reedvalve in the inlet , this prevents blowback through the carb
Yeah, in the center of the cranckshaft would be aweasome
Yes reed valves on each barrel and separate carburetors to stop the pulses from interfering
@@BrianjSiehr naah, 1 carb is good since this engine does not produce much power
It is a piston operated intake. Instead of reed valves the piston is controlling opening and closing the intake

You sir are the incarnation of Burt Munro and this the best compliment any person can give you. Amazing workmanship and know-how.

Men like him don't need an engineering degree. They are the ones who set the bar.

I get the feeling it would truly benefit from some thorough fettling.
As others have said, reed valves will fix that issue. Port timing/overlap that makes upper rev range power creates this issue at low rpm
Those expansion chambers are adorable! 😀 And made BY HAND!! 😜🖐👍

Needs reed blocks in the intake. fantastic build.
Piston port engines don't use reed valves. Notice no reeds in the disassembly of the original engine.
Might be worth remembering they started out as lawnmower motors,
they're unlikely to use or need reed valves.

I agree. If you see fuel blowing back through the carb, that pressure is coming from somewhere. All it would need is really light reeds.

Somebody stop this madman, there is no end to new engines!
Another fanatastic build. Great.
Great work as always! 🏍💨👍
Mấy ông Sư ( Kỹ Sư, Phó Giáo Sư, Giáo Sư..... ) Sĩ ( Phó Tiến Sĩ, Tiến Sĩ.... ) nên coi kênh của anh bạn này mà giúp dân giúp nước. Cám ơn Le Dan

Thank you for the content you produce in your videos. I enjoy watching you rebuild these engines in new and imaginative ways.
You build some amazing engines.

There is nothing like the sound of a 2-smoke! Reminds we of my youth when most street bikes were such except Honda. Great machine!
we want V10 two stroke turbo !
He needs donation for develop that thing
Le dan king engineering 🏆
You , Sir, are brilliant in so many ways.
Fine craftsmanship indeed.
Awesome little engine. Looks like a 2 stroke version of a BMW.
Genius Mechanic😄👍👌
Awesome skills!!
A true knockout !
Well done all around
Very clever. Impressive
Great skills....You are a genius💯👍👍
Fantastic great work and fun 😊
I am very impressed. What a cool project! I love it!
I must say this is definitely one of the coolest custom engine builds I ever saw maby ever!!!! Gosh Dang really Fine Work. What a beauty!¡!!!
You are a genius! Love your work, you are awesome!
Excellent workmanship Sir. What a great idea.
A zai mãi đỉnh
Badass great job!!
Ле дан как всегда красавчик. Милион подписчиков тебе
Amazing work
Genius man 👍👍
Quá OK luôn bạn ơi! Ngưỡng mộ bạn quá
Le Dan you are a crazy genius!
Ngưỡng mộ bạn, bạn đúng là thiên tài
nice engine
Wow. awesome work! That's a very nice bike you made!
Man, you are a genious!!!
Incredible work. You turn scrap into gold.
I'd like to see a twin cylinder made from two Honda Gx200 engines. Any type, inline, vee, or flat twin.
You are AMAZING Le Dan truly......Thanks very much....

YOU ARE THE BEST 🏆🏆🏆🇧🇷🇧🇷🇧🇷
I like the bike fella. Nice work .
Awesome work .yes a read valve or twin carbs/filters be a good addition

vc só tem q parar de por seus motor em uma moto com marca e sim com seu nome le dam. vc é um genio ....
My favorite is when you fly cut the big gasket surfaces! SO Satisfying! 😋🥰Well, that and when you ride the bike down the road!! 🤣😂
Better than a BMW and looks real cool too.
Гарно коли є інструмент золота голова і руки. Дякую !
Absolut gute Arbeit und ein sehr gutes Ergebnis.

Brilliant 👍🏼
thats so cool man
You should add the alternator stator to recharge the battery 🙂
Very nice creation ❤
Làm thử máy xipo lên 4 máy đi xem nó vừa rống vừa nổ kiểu 2 thì hay lắm đấy anh Dẫn mong anh làm thử❤❤
Quá giỏi chế cháo
Làm tốt lắm Dan, tiếp theo là 6 xi-lanh nhé 😁😁🤘🤘🇹🇭🇹🇭
最高です！
awesome job, 1 watch a lot of "I use this to build that" videos. Even though I am not talented enough to build an engine from a kit. lol
Gắn cục máy vào xe cud ok ah 😊😊
I love it 👏👏👏👏
2 thì đỉnh quá bạn
Present Bro from the Philippines 🙋
Tôi rất nể anh vì anh tài giỏi❤
That's a lot of fuel mixture blowing out the throat of that carb
One possibility would be to construct a fair sized air box to “contain” the fuel mist, and then fit an air filter.

Vá hay luôn anh ơi
Хороший инженер кнструктор❤
Khâm phục trình độ của bạn. Nghiên cứu ứng dụng máy nông nghiệp cho bà con nhàn đi bạn.

Beautiful little cafe bike
làm con 2 hoặc 4 thì boxer 4 piston đi a.
Em nó quả thật rất tuyệt vời . Động cơ xe máy HonDa là em nó hiểu hết thuộc lòng .
Брат,ты сделал,шедевр,и мой вечер
Excelent 🔥🔥🔥🔥
Tuyệt vời nha bạn
Totally cool
Masterpiece
Tuyệt quâ anh
Hi, Le Dan!! 🏍😃❤👍 From USA!
superb
Cool,, 👍😎👍
😍🥰love 2 stroke
Khi nào làm luôn máy dầu nha bạn
Всё чётко,ещё бы добиться более больший крутящий момент😊
звенит как убитая дешка с конскими люфтами. Бенз из карба летит наружу весь) Как демонстрационный образец пойдёт.
U my guy qre the best creator and machine man i have seen ❤
Can u do something with CVT again if u have the chance?
u r tatally from another universe..
Nice content. Please measure the maximum speed of each bike you modified

Bravo Le Dan 👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👍👍💪🏻💪🏻💪🏻💪🏻😃
I’d combine the Robin and the Honda tank logos to make a Ronda logo.
