Most of all. He could design for his own company. Move up to designing his own custom bike and automotive engine accessories. Such a manifolds heads transmission etc. could make a killing.
Definetly bad fueling, and i suspect its part because of the uneven firing and two cylinders sharing one carb. one gets rich one get lean, especially with a load on the engine. it needs four carbs :-)
@@hafeexius I think he talks about it at the end. Not sure if he reckons it's carb jetting or general setup. I'd guess its the fuel distribution from not running individual carbs to each cylinder. Something about the pulses at high rpm maybe?
Three ways to fix that running issue - use four carbs or use the two to feed one cylinder from each bank. That will avoid having one on compression stroke at the same time as one on exhaust stroke through the same carb. Thats why the more load/rpm you give it the worse it gets. You could change the firing order to both on one bank going off at the same time but that will double the torque loading on the crank and gearbox. You're so close - just a couple of minor mods and it will go like a champ. Top work already though.
I was sitting here thinking something didnt sound quite right with the engine, especially on acceleration. Im glad I saw your comment. It makes sense now.
The issue with two carbs could be eliminated by change the crankshaft so it has the pins at 360 degrees. Each bank will be even firing so for each intake stroke the carb will see the same pressure. Look at Le Dan's latest recent video showing the Yamaha exciter twin-cylinder, but using a single carb. He needs to build a new crankshaft and camshafts which is like building a new engine though.
exciting to see the engine finally mounted and hear the sound of the V4 engine. Excellent execution of your project build . As always, looking forward to the next project. Love it.
Khủng thật sự. Khối lượng coing việc khổng lồ , quá trời công sức bỏ ra. Thợ tiện cứng nghề lại am hiểu động cơ , hàn đẹp luôn. Chắc VN chỉ có 1 mình bạn xuất sắc như vậy.
The only project video which amazes and enthralls with the precise workmanship of very high calibre is only found on this channel. I normally skip all videos but this guy is just extremely talented ...ingenious engineering feats are part of his projects and that too from scrap. Lot of love and respect.
Sorprendente tu capacidad creativa para lograr tu objetivo ..eres muy ingenioso te felicito ..quedó espectacular y el sonido del motor ...sensacional ..saludo afectuoso desde argentina 💪💪
Your engineering skills are truly amazing for someone so young, an absolute joy to watch, the sound of that V4 on startup is beautiful, so crisp and all before any adjustments, reminds me of what you hear in a MotoGP garage, well done lad, Instant subscribe, 👏👏
You Sir, need an R&D job in a high flying blue chip company! What you've been achieving with these motors is pretty cool, but not hugely difficult. What's amazing is, you've achieved all these builds with the low precision tools you have around you. Imagine what you could achieve with a pro tool room! The mind boggles!
Cho bạn máy móc hiện đại đến mấy mà trình độ, tay nghề, sự khéo léo của bạn không có thì máy móc đấy cũng bỏ một chỗ. Cái thiên tài của Le Dan là ở chỗ đó. Trên thế giới này. Người có thể làm được như Le Dan chỉ một vài người.
i cant say anything that people haven't already said about how good you are. I hope you start building your own motorcycle brand one day. You deserve it!
Thats some mad scientist stuff lol. One thing ive learned over my 60 years is never underestimate what a bored man with a bunch of skills can build in his home workshop. Outstanding job mate. Insane, but outstanding.👏👏
Watching you machine down and put the engine together proves one thing your a very skilled engineer. Top drawer results. Amazing to watch. Great bike. Thanks for the video. ❤.loved seeing you measuring components and double checking by eye ...and just using your eye because you could see what you where after..Amazing.
Any person with this level of skill in a manual shop should be building prototypes for aerospace or major industry. If your one and only passion is a motorcycle, large motorcycle manufacturers will be recruiting you to help make their concepts come to life. It is the skilled operator of a manual shop that makes the first prototype and possibly many improvements. After that proof of concept is completed and perfected, the CNC machine will reproduce parts by the thousands or millions. Sir, my utmost respect to you for this great project.
I am truly impressed with the quality of this work. By the inventiveness, and the simple means implemented to accomplish such a big modification. We should even talk about creation, so everything is changed. I just have some concerns about reliability. I tell myself that the cooling may be a little insufficient, or that some original elements may be a little weak to receive the efforts of four cylinders instead of just one. But maybe you have found solutions to avoid certain problems. It's hard to estimate based on the video when you don't know these famous engines as well as you do. Congratulations and good luck with your projects.
Can you imagine some engineer from Honda watching this? He does all this work from a modest shop...no CNC..computer CAD...outstanding work!! Keep it up!!
astonishing work, your skills are developing even further... Have you considered building a small water dynamometer or doing any performance measurement? Would be very interesting to me, the risk for damage to these machines is my only concern. Your motors are my favorite type of art, thank you!
@@bimmjim Those motors take so much abuse over heating I don't believe would be an issue, they are oil cooled. I mean he should put a oil cooler on it and work on the jetting a little but besides that its art work what this guys doing.
I offer in constructive ideas, meant in a good ideas way.. ..the rear cylinders might need some baffle guiding plates to force air to stay around the rear cooling fins at speed, so there's time for the reduced rear banks airflow to absorb the heat, (like how was used on aircraft radial engine's cylinders), ..also maybe easier to do, slightly bigger main jets - to help with cooling, ..or/and perhaps an additional oil squirting jets into the crankcase (just below the piston barrel mouths) from another bike, to squirt some oil upwards onto/towards the undersides of the piston near TDC. Best of Luck Le Dan !!
I agree. Would fab sheet air deflectors to route air across the front of the rear cylinder, and across the rear of same. His design and build abilities are impressive.
Words fail me in expressing how amazed I am at your skills. There's a Moto GP team out that that should hire you! And the engine sounds amazing as well.
Great work. If you haven't already done so I'd highly recommend looking up Allan Millyard. He is an absolute genius and has engineered a number of custom motorcycles with various different engines, often built from two engines he has spliced together. One of them was a Kawasaki V12!
Những thứ bạn làm ra phải gọi là siêu phẩm, xem bạn làm việc tôi tự hào mình là người Việt Nam. động cơ này bạn nên sử dụng nồi chống trượt trợ lực ( Assit, clipper clutch) thì động cơ sẽ được khai thác hết công suất. Luôn vui vẻ khỏe mạnh nha Bạn.
Sort out the jetting in the carbies and new clutch springs you will need a new rear tire - well done, My V4- D16RR has a lot of power, I think yours will also with time and tuning - Good job !!
Really enjoy watching your builds. Very well done!! One question though.... Given the loose tolerances, how reliable are these engines, and how long do they last work regular use? Thanks
I had the exact same thought. I don't think these engines would last very long. The integral member structure, balanced components, and heat treat would be questionable at best, it's probably not recommended to make 50% of an engine out of welding rods... but I love watching this guy's creations.
@@GuildOfCalamityaren't the welding rods he's using to build these machines basically the same metal from which the individual components were originally cast...? Primarily, anyway. If the cases he fabricates together are high quality castings the aluminum is fairly "clean", and the TIG welding process isn't a novel concept in welding cast aluminum.
Impressive build no doubt but you're definitely have an issue with breaking up in the mid rev range. Could be due to ignition issues. I really want to hear this rip through gears!
HE WAS NOT A COMMON MECHANIC, IT WAS ANOTHER LEVEL. GREAT TECHNICAL SKILLS.
This is way past mechanic, this is a mechanical engineer.
the knowledge this man possesses is insane, he could design for any company it looks like.
Most of all. He could design for his own company.
Move up to designing his own custom bike and automotive engine accessories. Such a manifolds heads transmission etc. could make a killing.
@@musicemail2831 didnt you say this four months ago?
Знания, умения и талант этого парня бесспорны. Но нынешним компаниям нужны не инженеры, а маркетологи
The engine sounds awesome when stationary. When riding it sounded a bit rough. Maybe the carburettors need tuning.
Same here bro.....i think stroke not properly accurate or piston & valve timing some missmatch...
It's definitely misfiring and fuelling needs to be adjusted. But amazing work otherwise
I think it will be better if he has 4 carburettors an synchronize them.
Definetly bad fueling, and i suspect its part because of the uneven firing and two cylinders sharing one carb. one gets rich one get lean, especially with a load on the engine. it needs four carbs :-)

Outstanding!! Many blessings to you and your family from Perryville Kentucky USA
I've watched many of your videos. I fully believe that you are receiving telepathic guidance from another dimension. These builds are insane.

You know what you are talking about, sir. I have a HONDA VF 1000 R and it's exactly the way you just said. Greetings from Brazil.
At the end of video He did mention the motor needed some work.
How nice is it without music and especially what a wonderful job this man does 👏
Yup no retarded music for a pleasant change .
EXACTLY about music. Good to hear the natural world.
Wau. Master stuff!
I love these "tear-down-and rebuild films". And these guys working here sure know what they are doing.

I bet Le Dan really loves his work. My Dad would have loved a video like this.
One of your greatest Jobs. Well done. And the sound of your Le Dan V4 is fantastic.
Undoubtedly, but, definitely, the Master Craftsman, is looking at motorcycles engine manufacturers from his rear view mirror.
I can't even get around to changing the points in my 74 cb360. My hats are off to you my friend. You are amazing.
It seems more complicated than build a motor from zero! I can not believe it works!!! It's incomprehensibly mesmerizing!
Your welding skills have gotten much, much better. Especially when you consider how dirty that aluminium must be. Great job!!!
Я снимаю шляпу, это высший пилотаж!!! Все на глаз без чертежей!!!! 👏 👏 👏
This guy surely can build any type of engine.
Yep i thinks so, but Vietnam 's laws do not allow for modify the vehicles as engine, chassis... special is bicycle
any!
