What's amazing to me is the equipment he uses. Not a cnc machine in sight, all by hand. I can't even imagine what he could build if he had cnc machines to use. Awesome work.
I have been following Le Dan for many years now. Was not sure that a 2 Strike Horizontally opposed Twin could run with a common Crank case. I was not sure if the crank case compression would work. It does when the pistons are on the "downward stroke". Also helps with p[ort scavenging. Well it does an smoothly at that. Good one Dan. Next is to see this engine in a bike. Keep up the "back yard Engineering". you inspire us. Derek from, Durban, South Africa.
Great work a while back you made a horizontally opposed twin engine, but both pistons shared a crank pin and I pointed out that it wasn’t truly a boxer. I had no doubt that you could build a boxer and I’m glad that you decided to do it. Awesome work keep it up.
I repair bikes too but, man, if I had just 20% of the machining/precision skills Dan has, I'd be over the moon!! Good job Dan, I've been watching your channel for a long while and your work just blows my mind 💪🏼💪🏼
Thats a grate idea 💡! Boxer 2-stroke is one of the lowest vibration 2 cylinder engine designs. (Both cylinders fire at the same time, in opposite direction)

I didn't think the 2t boxer could have a shared intake because one side would greedily suck everything first due to any slight port asymmetry. The advantage of the 2t boxer is the perfect balance (the rocking couple is quite marginal) and the split bearing load. So instead of reservicing one big engine frequently, you replace two sets of stuff but not as often, nominally lasting twice as long, more like time and a half irl. It looks great!
I think it still doesnt run smoothly because not enough fuel get sucked in. Edit: as i watched the video at 18:12 he turns off the engine with only one sparkplug removed and in theory it should not happen. Maybe im wrong im not sure.
The holding bolts of the cylinder and crank assembly should be heavy as it is aluminium, we may see this on the road soon..you guys are crazy.... nice work..
You "le dan" Truly a genius mechanic, I'm always waiting for your video updates, and learning a little about machine customs . I admire how you use a milling machine and lathe with such skill and precision, it's really impressive ❤
Where did you get the angle gears? I want to use a vertical shaft engine (lawnmower engine) to power a trike with forward and reverse but can't find suitable angle gears. Do you know any common machines that i can get them from?
I have a few of those Robin engines and I love them, seeing you do this makes me want to do the same thing. you should build 2 expansion chambers for it now
At 12:10 you can see the oil pump drive gear is separate from the primary drive gear. When he spins the large gear only the primary drive gear spins on the crank because he hasn't fitted the clutch and the nut on the end of the crankshaft which clamps the gears together. When I say crankshaft, I mean what used to be the crankshaft in the original engine, now it is part of the 90 degree drive.
How on earth do you get crankcase pressure, when the pistons are sharing the crankcase and moving alternately, where is the pressure and vacuum coming from?
Sachs Wankel engine for the next project. Good luck finding parts, or just make it. Machine some rotor and make the apex seal in the shop your self.... 🔥
Can you make a boxer engine that has a cylinder between on top? So 2 90s. Basically a 4 cylinder radial but with the bottom cylinder taken off the bottom.
I'm pretty sure I ran across a maytag two stroke opposed cylinder washing machine engine years ago,at that time I was into old make and break fly wheel engines the man wouldn't sale it but allowed me to at least get it running
Nếu 4 thì kết cấu nổ đối xứng như này .cách nhau 2 kì thì quá tuyệt vời.Như này 2 thì tuy máy boxer nhưng kì nổ chung…xem ra như 1 máy…góp ý thôi…nói chung add quá good
should have blanked off those intake ports and run a reed on the crankcase... common crankcase, cus its opposed and simultaneous cycles... so only needs one intake... rather than two. which are still fed from a single carb... thats gotta cause some weird reversions and pressure waves on the intake... its nice but slapping a barrel onto a block with a two stroke requires a little bit of consideration of port timings and the like... if any of the critical dimensions happen to be different... stroke... deck height... rod length... piston skirt... then theres the pipes... nah, this one isnt fully there yet.
Air cooled motorcycle engines usually do not have forced air cooling (i.e. a fan). The cooling fins are large enough to cool the engine when the motorcycle is moving.
Dude, why and how are you not making engines for a major company yet ... You're doing the same work as a whole Development and Engineering team with less then 1/4 of the tooling a team of Engineers and Machinists has at their disposal or the budget, granted this is smaller scale work but clearly you've got the mind and talent for it.
Best thing I find with these custom engine builds by Le dan is the amazing quality and the flip-flops
What's amazing to me is the equipment he uses. Not a cnc machine in sight, all by hand. I can't even imagine what he could build if he had cnc machines to use. Awesome work.
His brain does the CNC part, just the way Allen Millyard does it.
As you see in the videos, there’s heaps to be done with a mill and lathe 👍🏼
Cnc just for mass production...
A CNC isn't some magic device for one off things like this a CNC would take some much longer and be no better
opposed motor yapsa daha güzel olurdu

I'm following you quite a while now. You always amaze me with your projects.
Another display of brilliance at the tailend of the internal combustion era. Thumbs-up!
"You have worked very hard on this item; I admire your precision work. Excellent job. "👍
Thats a grate idea 💡!

Hi Le Dan, Been here since the past years, Keep it up bro. Youve made it far. Congrats
Weer prachtig werk van onze Le Dan. Deze motor lijkt ideaal om af te werken met een luchtkoeling. :-)
Du hast mictg
Congrats ! A mindblowing piece of craftsmanship ! 😊
Once again, we saw a well-thought-out, skillfully implemented project.
Wow this is the type of stuff I want to see!!!! 2 stroke lovers check in!!! Great job!
Your running out of idea's now Dan you have made everything 😂😂🤘🤘
v12 outta 50cc engines?
He hasn’t made a straight 6 yet and put it in a motorcycle that’s one I wanna see
They will just get bigger and better i guess!
He needs to build a dyno to test all these awesome builds out.
@@cerberes that’s a good idea
love how low it idles down and how eager it is to run. Mr Honda would be proud ...............even though he did'nt like 2 strokes ............lol !
Tapered bearings would have been a better choice for handling the bevel gear axial loads. Ball bearings are not designed for that. Nice job!
Que maestro!!! un lujo como quedo.. mis saludos desde Argentina
Would love to see a more perfomance orientated build and then put it on a dyno. The aftermarket options are really big in your country.
That's a great engine project, Dan! Keep up the good work! Cheers!😁🔧🛠️👍
Great build. Thanks for stating the cc engine size!
Waiting for a video about a 1000cc crossplane v8 from 125 cc engines
Siempre me sorprendes con tu creatividad!!!, felicitaciones!! Abrazos desde Argentina..
You are a fantastic engineer and machinist
Cant wait to see with a proper exaust!
Another great build ! Can I see a spark jumping from the coil on the kick-start side cylinder ?🤔
Good one
V tunderious ..what could be the need of such engine am curious
The holding bolts of the cylinder and crank assembly should be heavy as it is aluminium, we may see this on the road soon..you guys are crazy.... nice work..
This guy alone out skills everyone in south scooter team. Talented and humble
You "le dan" Truly a genius mechanic, I'm always waiting for your video updates, and learning a little about machine customs . I admire how you use a milling machine and lathe with such skill and precision, it's really impressive ❤
Hey Dan..
You are a true master in enginering
Where did you get the angle gears? I want to use a vertical shaft engine (lawnmower engine) to power a trike with forward and reverse but can't find suitable angle gears. Do you know any common machines that i can get them from?
Động cơ này mà 4 thì nữa thì quá tuyệt vời luôn. Xem không rời mắt luôn. Thật ngưỡng mộ.
4 thì có làm rồi lun nhé bác
Good video Dan, no loud crappy music.
19:40 bottom left coil is arcing to engine?
I have a few of those Robin engines and I love them, seeing you do this makes me want to do the same thing. you should build 2 expansion chambers for it now
На 12:30 почему шестерня маслонасоса не крутилась при вращении вала?

When he spins the large gear only the primary drive gear spins on the crank because he hasn't fitted the clutch and the nut on the end of the crankshaft which clamps the gears together.

Wow you have a brilliant brain and super creative. Amazing fabrication skills
How on earth do you get crankcase pressure, when the pistons are sharing the crankcase and moving alternately, where is the pressure and vacuum coming from?
Crank case compression comes from when both pistons are on the downward stroke, ie compressing .
Cool bevel drive ! How about a small pull through supercharger to better fill rhe cylinders now they are sharing the crankcase ?
Desde México mi admiración y respeto eres un genio
Ωραίος ρε μάγκα, μπράβο !!!!!!
Đang mong chờ xem hệ thống làm mát động cơ sẽ như thế nào, và cả hệ thống mâm lữa nữa 😊😊😊
Mantap sekali kawan ikut nyimak sukses selalu
Amazing bro
But where is magnet coil 😮

You are so amazing..a mechanic's dream like me🙏
IT WAS SPECTACULAR, A BEAUTY
Gia bao nhiu mot dong nhu vay zay anh
so if get this tight the firing order of both position I mean the just fire at every stroke?

Nhìn cái trục khuỷu , em thấy có vẻ nó không thực sự là một động cơ Boxer ? Động cơ cấu tạo như thế này , cân bằng động rất kém ?
Anda memang hebat teman👍👍
I'm pretty sure I ran across a maytag two stroke opposed cylinder washing machine engine years ago,at that time I was into old make and break fly wheel engines the man wouldn't sale it but allowed me to at least get it running
what do you say about making a twingle two stroke?
What would one use the front flat crankshaft pulley for ?
Woww..2 stroke boxer done, .next 4 stroke boxer...
Quá tuyệt vời chờ mãi mới thấy bạn tesd
Nếu 4 thì kết cấu nổ đối xứng như này .cách nhau 2 kì thì quá tuyệt vời.Như này 2 thì tuy máy boxer nhưng kì nổ chung…xem ra như 1 máy…góp ý thôi…nói chung add quá good
sắp tới chinh phục đông cơ rotary đi a
Cái gì cũng biết làm đúng là idol 🎉 hay quá Dẫn ơi ❤
What firing order are you using, 1 - 2 or 2 - 1?
Absolute madlad
Bravo! Another excellent engine completed! :)
By any chance is this 2stroke engine for sale????
should have blanked off those intake ports and run a reed on the crankcase...
common crankcase, cus its opposed and simultaneous cycles... so only needs one intake... rather than two. which are still fed from a single carb... thats gotta cause some weird reversions and pressure waves on the intake...

Luar biasa sekali paman, kalau pakai mesin yang ukuran 150 CC pasti lebih optimal 😇😇 mesin ninja rr🙏🙏
At the magnet you should put a fan blade to prevent overheating cylinder block 😊
Air cooled motorcycle engines usually do not have forced air cooling (i.e. a fan). The cooling fins are large enough to cool the engine when the motorcycle is moving.
Fuel injector conversion with turbo kit plz 🙏 you could be the first firs to make real boost with a small engine

You can add cooling fan at the front
What kind of bike are you going to put this in? A scooter?
I’m thinking a seven cylinder radial for the next one.
can you make this into a bike and test the durability on the engine, and perfect it
good vid, keep it up!
Hey i noticed something, in the first start of the engine there is an electricity leak near one of the ignition coils
