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.

Absolutely agreed, his engineering skills are mind boggling. He has a good set of tools & machinery at though, to work all that out & manufacture something no one else does is extraordinary. Bravo I say

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.
hes been shown how to use the machines from about 12yrs old maybe younger ,i used same machines and a handfull of other hand set old pre 1940s stuff no cad or cnc ,id have no clue how to set one up give me a 1888 lathe and ill turn anything
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.
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.
So much precision work for making only a 100cc engine. At best it would have about 9 HP (6.7 KW). That being said, the skill and level of planning to do it is truly amazing to watch.
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.
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
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.
I was surprised he didn't (appear to) replace the main bearings, although he was very thorough about everything else as far as I can see. The engine sounds perfectly in tune both runs. Gifted man.

I absolutely LOVE this new Honda you made. Its beautiful, practical, and one of a kind. You should be world famous for making custom bikes. Id love to own one of your bikes. Hello from San Francisco.
That is a work of art. Sounds fantastic as well. Crude engineering. But this guy has some skills! I thought his Boxer engine was interesting but this a definite improvement.
You are a genius 👏 🙌..ask your mom what she had when you were in her womb ! 😊.excellent job. Mr. Soichiro Honda would have taken you in his R&D if this was done when he was alive. 25 years before.
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

Do it with puch 2 strokes instead. Might be more easy, as you do not have valves. I suggest puch, yamaha or honda cylinders.
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.

What makes it adjustable
@@icanbuildit4977 A lot of things, but if you watch the video there is an adjustable distribution system.

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...👍

this is the coolest thing i have seen all week
This video is the perfect example of how different crank degrees in parallel twins sounds:
180° crank 23:18
270° crank 24:50
360° crank 26:22
THIS IS UNREAL, id love to be able to learn from this guy
Bravo et respect mr le dan, excellent travail effectué dans cette configuration. Joli taf. Le Boss quoi ❤

Nice Job!! Love the sound it makes.
This has to be one of the most interesting videos on yt.
Craziest home engineer ever!
A new engine is born...amazing, Bravo!
Holy incredible, my only concern is cooling, fins are all the wrong way and I don't think there's any left on the back cylinder!!! LoL ❤❤❤❤
Impressive Le Dan. Surely a motorcycle manufacturer has to offer you a spot in there engineering R & D dept.

I much prefer the sound of the 270 degrees out. Once again, awesome job!
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..
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
rather than pull the motor apart each time. It might be useless but who cares, it's cool
I believe this should be called a Two-50!
