I built a yamaha mio engine to 2 cylinders 220cc, this is the first version I made a 270 degree journey, very happy to be loved and supported by you overseas, I sincerely thank you very much. #ledan #mio2xilanh #yamaha
this gentleman is amazing , i have rebuilt scooter engines and sportsbike engines over the past 30 years . from gy6 to gsxr1000/r1,s and many others .and i can say this guy is mind blowing . skillz ,respect
Somebody give this man an award something! This is pure passion and engineering at it’s finest! Working with what you have and showing that sometimes we do t have to go and pay some fancy machine shop . It’s knowing the true value of mathematics and accepting no as an answer ❤
I wonder what cc is it. But i bet its a 350cc. And sound so good. What more if its a 8 valve 🤤🤤🤤 it will be an overkill build. What a briliant mind you have sir 🙇🙇🙇❤️
Genial todo tu trabajo : cálculos de acoplamiento , rectificado de cárteres ,soldadura de aluminio y una buena dosis de trabajar bien y con entusiasmo ( la clave de tus logros ) .Felicidades Le Dan.👍⚙🔧
I tell you what man I was skeptical at first but I've watched a bunch of your uploads and you really got this shit figured out. Huge props bro because you're good at this. Keep up the good work, I look forward to more.
Bro! it's very nice to see your videos again it was so satisfying I wish I have time to make one my own, anyways ur build is nice u decide to put stock 50mm I taught u put 59mm to be 320cc but still ur build is very awesome! my another suggestion since I notice your engine shakes a lot put a counter balancer shaft opposite weight to the crankshaft and then dynamic balance it to cancel stresses and vibrations or if the engine is tolerable just put somedouble reinforced rubber mounting between the engine engine mounts
@@gussrestu yg saya lihat dari pembuatan mesinnya ntar mudah jika di bongkar pasang. Beda ky builder lokal biasanya fokus pd hasil untuk servisnya susah...
@@hocpham412 oh I didn't know that!! World knows of Vietnam capability, but what they don't do attention is for these two lil countries like Thai and Philippine.
Thứ mình mong đợi cũng đến. 2 pit tong hành trình khác nhau. Tuyệt vời. Ơ mây zing gút chop pro. Mong ngày nào đó được sở hữu sản phẩm như thế này của bác 😘
For once someone finally does a custom made inline twin engine with a 270° firing order, the 360° custom made ones are way too common from where I live. Hopefully someone does a 270° firing order onto a custom twin engine in here
180* opposed cylinders is most efficient. 270 is going to cause the crank to beak before long or kill the rod bearings. with how much the motor was sliding all over the place past idle you can get an idea how imbalanced the rotating assembly is and causing severe internal vibrations.
@@chehystpewpur4754 The 180 is still imbalanced. Why would it have better rod bearing longevity? The interference fit of the pins and flywheels simply needs to be sized to take the torque from each pin accordingly. It's worth bearing in mind that back in the day even 360 twins had no balance shaft; probably why they never grew much larger than 650 cc in practice. There's a small chance this crankshaft is over-balanced for the application, seeing as the flywheels came from an engine with a balance shaft.
@@identiticrisis your thinking way too into this. because no. this guy has been slapping motors together like this for years. there is no precision like your claiming he doesnt need it or care. some of his videos the pistons are in backwards. the smoother you can make an engine the longer it will live ive built many motors. a strong bottom end will keep you going. a crank that shakes itself to pieces isnt gonna win any races. what im saying is 180 out is the same thing everybody in the world does because its proven to be true. v8 2 pistons opposed v6 usually. 4 cyl 2 up 2 down. a few tried 1 up 1 down but harder to get there. most 2 cyl is 1 up 1 down 180 out. on 2 stroke thats the most power you can make. there were twin cylinder 2 stroke that both fired at the same time but their too hard to ride so they opposed the pistons to smooth out the power. the more power you can put down the more fun the ride. if you have bangs and spurts of power all over the place your gonna crash. or the motor will. the other thing is timing bro. nobody understands that shit. the crank spins 360 degrees 2 times and the cam spins 1 time. so now you have this motor over here doing one thing and the other one is doing something different at different time. you connect the cranks and it runs like poopoo. 180 out everythings in time theres no frustration easy to start easy to ride and your always making power. not losing it.
@@chehystpewpur4754 I made no comments about required precision. Which presumably still needs to be better than the several hundred grammes of reciprocating weight per bore. Plenty of races won with shaky cranks, btw. But then back then they all shook, is my point. Most twins designed today have balance shafts and 270 cranks, for what that's worth. Would have happened sooner if people listened to Phil Irving in the '60s. Why do 180 twins have better rod bearing longevity?
Impecable , una grandesa en su habilidad como mecanico y constructor. Deberia estar trabajando para honda , yamaha , suzuki , kawasaki. Con pocas herramientas tranformo un motor nuevo.
