Since It's air cooled and the second cylinder sits behind the first one it will probably suffer overheating though. Not enough air-flow for the second cylinder I fear.

Rotax made the bmw f800 parallel twin adjustable. It figure a third rod for vibration dampening and is set up at 360° on the f800 line but 315° on the Husqvarna nuda 900 twin. Also the two bike really works differently. The BMW have multi-plexing, the nuda not.
@@4sstylz f800 is not adjustable like engine in the video because you need replace crank and camshaft to change it from 360° to 315°. If you change those parts you can modify every pallalel twin to any offset between firing. Engine in the video is adjustable because you can change angle between cylinders without any additional parts, its just unscrewing some parts and adjusting them to work differently.
To be fair two strokes are 65% dark magic, 20% resonance and 5% of autism. Once you figure out that you never actually learned anything about the inner workings of them besides the name of the parts and surrender to impulse, you'll be able to build anything 😂

It would have been a great and fun project to do. But this guy demonstrated that it would require so many high precision tools and so much knowledge to do. I can only sit here and admire.
The 360 works better because you have a combined intake, in this configuration there is no overlap between the two cylinders and the carburetor is able to deliver fuel and air better.
@@Drosba With 180 degree timing the out of balance forces with the pistons halfway down the bore would add, increasing vibration. 360 degree could give perfect primary balance if the crankshaft counterweights are adjusted, as helixworld says.
Thank you for finally making the Honda 100 cc twin that should have been made after the Yamaha Twinjet 100 came out back in '66. Everyone was expecting a twin 100 but Honda brought out a single instead. Now we know what could have been. Thanks again.
great examples of splitting fires for the same volume.. and showing a derivative that is balanced and unequal. More than ingenuity, this video has a lesson.
Some people just have excellent spatial reasoning skills and don't need any fancy CNC machines. I've ground a rod for an 0.010 over bearing by hand with a file and crocus cloth and the car is still going strong 14 years later. I'm definitely impressed by LeDan's work but it is also something I could do myself if I were determined to do so. I've been toying with the idea of making a pushrod boxer twin using aircraft engine cylinders. Would probably use Lycoming O-235 parts for a displacement of 117.5 ci, along with a blower, and put it in a drag bike to go up against Harleys.
The most beautiful and accurate timing engine I have ever seen Hearing the sound of the engine, the young master performed the accurate timing from the lower gears One top dead center piston and two bottom dead center pistons I also know turning and some mechanics and welding, but our young master taught me a good lesson today Master, may you always be successful in your work
This is the guy that can do what I have been thinking of for 25 years. A hydraulic pump that emulate the 3 phase characteristics of electrical power. If there are three pistons at 120 degree in between, it would theoretically be an even flow and pressure of oil. The same way three phase electricity works.
You are a true mechanical,, ✨🌟✨ Could you fit one more,, 😆. I looooove the pull from 3 cylinder, 120 degree. 🥰 Nice to see that you have invested in a sandblaster box,, 👍👍. Fresh blasted aluminium with clearcoat on top looks very nice. Thank you for sharing,, 💖🙏💖
Honestly one of the coolest channels out there, I love this stuff and its really interesting to see someone push the limits of whats possible. Can we see a 6 cylinder engine made from those little SOHC honda engines next? A DIY Honda RC166 would epic!!!
Amazing work. I'd like to suggest another version. Add a clutch to allow you to disengage the second cylinder, then another level to adjust the crank angle(TDC) then release the clutch. Kind of like a VTEC system but for the actual crank angle between piston stroke, all while the motor is running. I don't think it's ever been done before
I am confused as to how the second cylinder valve timing works as it is revolving in the opposite direction. You are a genius with the things you make.
This is just awesome. The 270° idle sounded amazing. Fantastic work!!!
I'd LOVE to see 8 of the 50cc put together to make a 400cc V8.

id love to see little honda gx25 - 25cc engines put into an inline 4 configuration for an inline 4 100cc
Do it with puch 2 strokes instead. Might be more easy, as you do not have valves. I suggest puch, yamaha or honda cylinders.

this dude single-handedly beat the big manufacturer of motorcycle war on Firing order by building an adjustable firing order paralel twinhahaha
What makes it adjustable
@@icanbuildit4977 A lot of things, but if you watch the video there is an adjustable distribution system.

@@Dymitr_Nawrocki You're right. But the number of engine with more than 1 firing order is prety rare.
still amazes me how his brain wrapped around this and made everything work ... cool

@@jerekalevijarvinen1389 this is not a 2 stroke dude, clearly you have not learned even the names and parts
It's really easy just take about 7 grams of mushrooms in a machine shop and when you come back to reality something amazing will have been built 😂
@@jerekalevijarvinen1389 It's clearly a 4 stroke...
Crazy that one person knows how to do all that. Well done. 270 degrees had the best sound in my opinion. Thanks for the video. 🙂

yes but with H2
It would have been a great and fun project to do. But this guy demonstrated that it would require so many high precision tools and so much knowledge to do. I can only sit here and admire.
The 360 works better because you have a combined intake, in this configuration there is no overlap between the two cylinders and the carburetor is able to deliver fuel and air better.
and there's perfect engine balance with contra rotating crankshafts at 360degrees i think. that should improve performance.
@@martin-vv9lf That would be the 180º, with 360º they move up at the same time and then down at the same time.
@@Drosba The contra-rotating crankshafts can have perfect primary balance if the counter weights are increased from the single cylinder design.
@@Drosba With 180 degree timing the out of balance forces with the pistons halfway down the bore would add, increasing vibration. 360 degree could give perfect primary balance if the crankshaft counterweights are adjusted, as helixworld says.
360 sounds good like an English twin,
Wow !! this was astounding. Most people couldn't do this with a pro machine shop and look what he did. I'm impressed.
Like I Said...👍

Sunbeam S8? Best build yet? Genius....on a shoestring. Admiration!
No, on flipflops.😏
This dude is a genius I wonder how he figures out all the things that would make something like this work
Mind blowing how you designed to the angle to be adjustable. Genius work. Thank you. Enjoyed every moment of the work. And the sound...
great examples of splitting fires for the same volume.. and showing a derivative that is balanced and unequal. More than ingenuity, this video has a lesson.

It turned out very cool. And if you do it with two exhausts, it will be absolutely gorgeous.
I love the flexibility of the engine design to switch from 180 to 270 and 360. degree
Simple. A work of art. Well done!
Absolute genius. Greetings from the Netherlands.
Great build! This really illustrates the different firing angels and their sound - awesome!!!
I never get sick of watching this craftsman at work.... 👍🏻👍🏻
This has got to be your best-sounding creation yet.
The thought and effort needed to bring this together is amazing...
Damn a U engine moped never thought this could be done. You are awesome dude
Now, let's make it 2 stroke. 👏👏👏
I keep asking for more 2 stroke content. But not sure if he can see these comments
@@josephwu3136 Me too, still waiting for 2 stroke engine mods.
Incredible Build. Very impressive!
That's both interesting and satisfying to watch!! The man is a GENIUS!!
Notice how enormously vibration free that engine is, as it has two counter rotating crankshafts!
Wonderful work! You sliced everything as you were slicing bread. You joined everything as you were glueing papers.
This is incredible! Amazing somebody can make this
The most beautiful and accurate timing engine I have ever seen
Hearing the sound of the engine, the young master performed the accurate timing from the lower gears
One top dead center piston and two bottom dead center pistons

Master, may you always be successful in your work
this is literal magic! sounds so good, too!
Engine sounds great,..more like a larger engine. No shortage of" get up and go".Real talent and craftsmanship;...
A true engineer.
One that isn't phased by engine block cracks, but still, a true engineer 👍
This guy's thinking & skill render him worthy of a Millyardian cup-cake . . . maybe even two! : )
Awesome bro,im always impressed by your builds. Cheers from Australia
another great build..👍🤘
Amazing machining work, great job!
It sounds so good!
Damn awesome work bro. It's beautiful.
Amazing conversion.
Awesome build and work.
awesome build it sounds really good.

Such a talent !!
Incredible the sound of this engine!!!
you really have a talent for this! Great JOB!!!!!
What a tiny little beast! I want it:)
I would love to have this bike. What a work of art.
The amount of joy and intriuge these kind of videos make for me is unreal. I love the mechanical engineering world so much

rather than pull the motor apart each time. It might be useless but who cares, it's cool
Simply amazing!
I like the 360 degree best. The muffler sounds quieter and less raspy than the "NLK Thailand" used on the V-Twin from November 2021.
It would be interesting to see you a 4 Cylinder version of this. Like the old Sunbeam and the Indian motorcycles of the days.
Sounds awesome
100 cc upgraded with style. What a skill
Good work and I loved the surface finish from the simple fly cutting - but I think it will overheat and that rear cylinder will seize..
This guy kind of reminds me of Allen Millyard Great work!
Le Dan .. you are impressive .. no end to your extraordinary skills 🙏
Great work, perfect! (Brazil)
I liked the 270 degree firing order sound. Be cool to hear it with the Harley firing offset.
wow wow wow. Would love to see u make two 50cc into a 100cc U engine in flat (boxer) configuration! Great job man!
Sounds like an old triumph!
AMAZING!....and unique!!
Damn, that Engine sounds so good....😍👌🏻 Nice Work, you're a Pro🤟🏻
Wow… that sounds obviously much easier than it is 😮❤ great job. Interested in the durability of all the welding joints 🤷🏻♂️
