What a beautiful engine with an ingenious 3-speed gearbox! It is very special that people made such beautiful things at that time. Very good film of the restoration!
@@michaelb.42112 Yes it is an amazing little engine. The quality way better than anything made today. But I wouldn't say it was ahead of its time. Remember the Vespa came out in 1946. It's just that back then people did things right.
My 1970's Garelli Tiger-Cross 50cc moped , 4 speed gearbox, was very similar in operation. It used the same sort of plunger to push out the balls to engage each gear, although the balls were extended with short rods.
what a beautiful little engine - why can't they still be made like this today. You have to admire the engineers who designed this in the first place - truly incredible.
Emissions is one of the biggest reasons. This thing is a 2 stroke which means three things: an absurd power to weight ratio, mechanical simplicity, and pretty lousy emissions. You just can't make an EFI four stroke (mandatory for modern emissions controls) that matches it for simplicity and lightness.
@@ironhead2008this. This is the reason why you dont really see two strokes on the road anymore (dirt bikes dont go on the road as you know) even though they were all the rage in the 70’s. Even though 2 strokes are a lot more efficient than then used to be in the past, their prime has passed.
My God, this is the coolest thing I've ever seen. I had NO IDEA these mods were available when Roswell happened. How ahead of their time. 60cc on a bicycle is INSANELY fast !!!! I would've given up 1982 Christmas to have one of these !!!

Коробка передач с шариковой фиксацией - это, конечно, гениально. Нигде ничего подобного на современной технике не видел. Подозреваю, что из-за ограниченности передаваемого крутящего момента, а также из-за развития традиционного вилочного механизма с бронзовымм синхронизаторами. Однако по меркам 40-х годов, когда даже на машинах обычным делом была КПП на 3 передачи без синхронизации, которая требовала двойной выжим сцепления для плавного переключения без рычания и хруста, вот такой компактный механизм 3-ступенчатой КПП был действительно гениальным решением. Ведь, из-за отсутствия угловатых элементов (таких как шлицы для зацепления шестерни с валом) передачи должны включаться мягко, а для их смены не нужно даже нажимать сцепление. Плюс, управление с помощью всего одного штока, расположенного внутри вторичного вала, делает весь механизм компактным.
Откуда там взяться "мягкости" включения)?Если не угадал,будет тот же хруст.единственный плюс таких механизмов-компактность.Слабенькая схема.А чтоб КПП прощала хоть как-то грубое включение тут уже нужен демпфер на сцеплении.А здесь дальше скорее всего была ременная передача,и могла работать,как сцепление.Увидим в продолжении,что там и как.
@@kotborka именно хруста в таком механизме в принципе не будет, потому что хруст - это когда шлицы вала и шестерни друг по другу скачут, но не могут зацепиться. А тут нет шлицов, потому что вместо них шары. Если механизм слишком быстро крутится в момент переключения - на переключателе (ножка там или рукоятка - хз) просто будет ощущаться сопротивление до того момента, как скорость вращения достаточно снизится, чтобы шток продвинулся и затолкал шар в пазы.
@@kotborka хруста там не будет в принципе. Потому что хруст - это когда угловатые детали скачут друг по другу. А шары круглые, выемки тоже. Я не пробовал такую трансмиссию, но опыт подсказывает, что при переключении передач на повышенных оборотах будет просто изменение тональности звука, до снижения до приемлемой скорости вращения. Это какая-то секунда, что не сравнить с хрустом вилочного механизма, который при спонтанном переключении без сцепления (да, я пробовал - на той же ВАЗ 2109 переключаться так можно, но при тонком подходе) может звучать несколько секунд и сопровождаться скруглением шлицов, которое вскоре приведет к выбиванию передачи.
@@nz3230 Молодой ещё,зеленый))!Шарики хоть и круглые,но пока не зайдут в зацепление,удары неизбежны,и будет это чем-то похоже на отбойный молоток или дрель с ударом,если включать грубо без сцепления.Да,можно и без сцепления тихо переключаться,особенно вверх,на разгоне.Но во-первых,нужна кулачковая коробка,чтоб были хорошие зазоры между кулачков,чтоб передачу можно было втыкать при некоторой разнице в скорости шестерен,нужен демпфер в сцеплении,чтоб сглаживать неизбежные удары,и кпп авто с их шлицевыми муфтами ,сидящими на шлицах почти без зазора практически не подходят для этого.А вот на мотоциклах вполне можно ездить без сцепления,или почти без.На разгоне даже газ обычно не сбрасывается,только чуть выжимается сцепление и передача сама входит).На снижении скорости приходится играть с перегазовками,иначе не включишь.Но можно.Так что хоть округло,хоть угловатое,но это железо)),удары неизбежны.
A trick I learned back in the day to time an engine with breaker points is to find an AM transistor radio and tune it between stations so all you hear is static, when the points fire you will hear a tick from the speaker

You can’t see it clearly from the video, but there are a lot of empty spaces in the crankcase that are not occupied by grease. Also consider that during operation the grease will tend to melt and this will leave even more space
@@Ego.Reficio Жаль,что по сути уплотнений нет и нельзя залить жидкое масло.Хотя если постараться,то можно крышки доработать и установить современные резиновые самоподжимные манжеты и заливать обычное масло.
Thank you! For the moment I have found only those nests. Perhaps because the engine was for several years on that shelf and the place where it is located is very hot in summer
I am impressed with your skill and even more with your attention to detail, most impressed ... thank you for sharing your enthusiasm for restoring these older machines ...
Speaking of Italian build quality, I bet that little motor will outlast 100 of those China 80cc bicycle motors they sell online today. Italians make some fine engines. Minarelli motor in my rough house moped is the strongest 50cc there ever was unmodded.
Great close up shots in video! I like how you showed the process of restoring the parts, and I'm surprised that instead of oil , grease was used in the engine.
Thank you! Grease was used because oil seals had not yet been invented. In fact, the fat being more viscous than oil makes it more difficult to get out of the holes. If you see the point where I take the breaker contact plate off, below it is a kind of brass washer and a felt pad, not an oil seal, just because they didn’t exist yet
Ah, sweet memories of childhood. I remember mounting such one on a Mishutka children bike, so my mom would allow me to store it in our small apartment, because the motorbike would be too big to fit in the elevator. Technically, you could wheelie it in, if it weren't for the exhaust... Ended up renting a garage.
Dans mon enfance, juste après la guerre, il y avait plein de petits constructeurs de moteurs pour vélos, qui utilisaient un galet pour entraîner un pneu par frottement. A 12 ans, en 1960, j'avais ainsi fait un petit tour sur le vélo motorisé du père d'un copain de mon âge, avec un moteur Garelli. On était loin du vélo à moteur des frères Werner de 1898, dont un seul est encore en état de rouler et que j'ai eu le plaisir de voir tourner en 1986 sur le circuit du Bois-Guyon à Dreux. Salut et fraternité*
Un intervento effettuato alla regola dell' arte su di un piccolo gioiellino d'ingegno senza tempo, il tutto con un ottimo editing video; piacevolissimo da guardare non annoia mai. Bravo!
packing bearings with wadding to push them out is something an old bloke showed me on my rally runabout engine back in 1972-3, I was amazed at how easy they came out after I had struggled for ages trying everything I could think of, I was only 12 - 13 at the time but that lesson stuck with me, This guy making his own condenser ! anyone who wasn't totally absorbed with this video is brain-dead,
I'm engineering technologist i was watching yours hands how you was using the tools, for me your gasket cutting greasing oiling and seating the engine covers were fantastic.
Thank you! That shape of the piston is called a deflector, helps the escape of the combusted mixture and was used on the old two-stroke engines, where a lot of oil was used in the mixture because the oil at that time was of poor quality so you had to use more to get a good lubrication. This engine uses a mixture with 8% oil (in a liter of gasoline should be added 80ml of oil!)
Saludos desde España...has realizado un trabajo exquisito con esta restauración...desmontando hasta el último tornillo para dejaro todo casi en estado de fabrica...He pasado un rato entretenido observando como realizabas todo el proceso de restauración...Ahora solo queda verlo montado en una bicicleta y funcionando....
Thank you for the compliments! in the continuous of this video I will make a conservative restoration also on the bicycle and I will mount the engine to try it etc
Damn, that new condensor in the old housing was pretty cool! Also finally someone who uses a proper spark plug from Magneti Marelli (one of the best manufactuerers of spark plugs), not totally unfitting NGK.
Awesome. For those who don't know this they actually still produce bicycle motor kits to this day. Basically a similar design but just made in china. They can work great, last a while, costs $100 or less on average for an entire kit too
There were many such motors in post-WW2 Europe each with different levels of technical refinement most being very basic. By the second half of the 1950s, most fell by the way-side as living standards began to improve but from the technical perspective, I think they remain interesting.
Такой маленький двигатель и при этом трехскоростной! И это 1947 год. Советским дырчикам 70-х...90-х годов до этого итальянца далеко. Так же как и выпускающимся сейчас в Китае аналогам советских д-8.
The connector I used is a new old stock, and it is exactly the type that was used in those years. Why should it be replaced? As I said in other comments, the test I will do in another video because this came out very long. It still lacks to restore the bike, the tank and the crown
@@Ego.Reficio it is clearly seen in this video, that there is a bad contact between spark plug and connector. The connector just shakes on the plug and it is defenitely not as it should be.
From the video is not very clear, but the connector inside has a spring that holds the pin pressed near the head by the spark plug. Also consider that once I put the wire, from the crankcase to the spark plug, the wire is slightly pulled and then the connector holds well in contact with the spark plug
Thank you! You’re right, it’s not my first rebuild. I’ve been enjoying restoring small engines and more for several years now, it’s just lately that I’ve decided to make videos to show them
And all using low-cost and readily available tools, chemicals, and materials as well! Quite valuable to the broke among us. Would have loved to see/hear it run, better yet, mounted and functioning as intended. Thank you for making and posting this! One suggestion: on-screen graphic of generic description of what is shown- for example: “soft brush scrub with phosphoric acid-based cleaner” or “must use brass-bristled wire brush wheel to minimize scoring of cast aluminum”, or “kerosene, mineral spirits, or parts cleaner in ultrasonic cleaner” - would also be very helpful to the novice or beginner. Just a thought.
Thank you! The video does not end like this, there will be another video where I mount it on the bike that you see on the cover and start it. I didn’t put this part in this video because otherwise it would come out too long. For adding a more accurate description, thank you for the advice, but from the statistics of each video, the subtitles, and then the description of what I do /use, is seen very little
From the video, it's not very clear, but in the engine casing, there are many empty spaces not occupied by grease. Also, consider that with heat, the grease tends to become liquid and leaves even more space
@@Ego.Reficio No, I should have specified that in my original post. We use the recycled beer can ones from China. They are very similar but the quality isn’t even close. They aren’t bad once you now what to address when you get them.
I understand. I’ve never had one of those made in China, but I think they’re still fun to use. How do you solve the problem of having the license plate and the insurance, in order to move on the street?
@@Ego.Reficio in my state( Ma. ) As long as the engine is under 50 cc, it’s considered a moped and doesn’t require registration or insurance. My engine is 66 cc but I have a sticker that says otherwise. They really are super fun and much cheaper than electric. Well, for now at least.
my comment is somewhat different, for the time period this engine is a well engineered piece of equipment. simple yet efficient, we always thought Italian stuff was cheap trashy and nasty. now as an old man I look at this engine with different eyes. Italian's did really well with what they had after the war, hats off to them.
I’ll make another video where I’ll do a quick conservative restoration of the bike. I’ll mount the engine and test it. The video will be released in early summer

grease is the more accepted way. you wrap more or less electrical tape around the thread of the bolt to improve the seal.

@sasquatch_886 hey, for 100 bucks, it's worth it just for the learning experience.
wow and give it to expert sir for rebuilt
Μπραβο φιλε πολλη ωραιο το βιντεο. Καλη συνεχεια σε οτι κανεις.Χαιρετισμους απο ΕΛΛΑΔΑ.
Thank you!
I can't wait to see the video with the engine starting 😁.
really compliments, excellent restoration
Thank you! Stay tuned 😉
5:30 ASMR stands aside
Eccellente lavoro! Excellent work! 👏👏👏
Thank you!
Great video, thats one heck of a thorough restoration!! 😮
Thank you!
Isso sim é uma restauração de qualidade!! Like e inscrito do Brasil
Thank you!
Отмыть главно, это самое сложное и время всего больше на это уходит зато сборка качественная получится и собирать приятно и все мелкие дефекты видно
There were many such motors in post-WW2 Europe each with different levels of technical refinement most being very basic. By the second half of the 1950s, most fell by the way-side as living standards began to improve but from the technical perspective, I think they remain interesting.
That’s correct. I think like you about the interest these little engines have
Magneti marelli é mesmo de renome 👏👏👏
Trabajo impecable! Felicitaciones! Yo 1948😊
Thank you!
Beautiful restoration build Sir, you are a Master with lots of patience, subscribed and thumbs up, thankyou for your time
Thank you instead for watching the video and for the subscription!
Такой маленький двигатель и при этом трехскоростной! И это 1947 год. Советским дырчикам 70-х...90-х годов до этого итальянца далеко. Так же как и выпускающимся сейчас в Китае аналогам советских д-8.
Sir make vintage engine restoration video
The spark plug connector needs to be replaced, or just a nut onto the spark plug. And it is not a finished restoration without a test run)
The connector I used is a new old stock, and it is exactly the type that was used in those years. Why should it be replaced? As I said in other comments, the test I will do in another video because this came out very long. It still lacks to restore the bike, the tank and the crown
@@Ego.Reficio it is clearly seen in this video, that there is a bad contact between spark plug and connector. The connector just shakes on the plug and it is defenitely not as it should be.
From the video is not very clear, but the connector inside has a spring that holds the pin pressed near the head by the spark plug. Also consider that once I put the wire, from the crankcase to the spark plug, the wire is slightly pulled and then the connector holds well in contact with the spark plug
Now THAT was a well-made video. And a nice little engine. Seems to be not your first rebuild. Nice.
Thank you! You’re right, it’s not my first rebuild. I’ve been enjoying restoring small engines and more for several years now, it’s just lately that I’ve decided to make videos to show them
@@Ego.Reficio I am really interested to see the finished product. That valve and actuator on the head intrigue me...
Stay tuned!
Great job. Shame couldn't see it running
In the next video you will see😉
È proprio un bel canale, grazie.meglio quei tempi che quelli odierni, secondo il mio punto di vista.voi che ne pensate?!
Thank you! I think they were very different from our times. For some things they were better for others not. Surely they were a fascinating time
The inside is clean thanks to the large amount of grease.
A joy to watch👍🏻
Dam I wanted to see it run!!
Super Robota !
I use a modern two-stroke! It's erasing spec, over square and it's the phantom 85 V3. My 26-in beach cruiser can go 50 mph.
Is this engine also made in China?
Hmm, a ball-lock gearbox. Interesting. They are not used anymore AFAIK, the last motorcycle manufacturer to use ball shifters was Hodaka.
10:00 Ah yes the forbidden coca-cola
Very nice! Thank you!
Even got a Magneti Marelli spark plug.👍
Excellent work
Cool motor
tenho uma halliener motorwerk de 1953, 2 marchas só falta o magneto, que é parecido como da sua!
And all using low-cost and readily available tools, chemicals, and materials as well! Quite valuable to the broke among us. Would have loved to see/hear it run, better yet, mounted and functioning as intended. Thank you for making and posting this! One suggestion: on-screen graphic of generic description of what is shown- for example: “soft brush scrub with phosphoric acid-based cleaner” or “must use brass-bristled wire brush wheel to minimize scoring of cast aluminum”, or “kerosene, mineral spirits, or parts cleaner in ultrasonic cleaner” - would also be very helpful to the novice or beginner. Just a thought.
Thank you! The video does not end like this, there will be another video where I mount it on the bike that you see on the cover and start it. I didn’t put this part in this video because otherwise it would come out too long. For adding a more accurate description, thank you for the advice, but from the statistics of each video, the subtitles, and then the description of what I do /use, is seen very little
Very nice and videos form my india🇮🇳🇮🇳🇮🇳🇮🇳 bro❤❤❤❤ so love you ❤❤much
Thank you! ❤️
Аккуратно, без спешки.. и отличный результат!
Thank you!
What is the purpose of filling the engine compartments with grease?
Great video thanks.
I did this because the gears need to be lubricated, and because the engine doesn’t mount the oil seals yet, the oil can’t be used
@@Ego.Reficiomy grandpa said dont feel bearings and gears more than 1/3 with grease to let mechanisms go freely...
From the video, it's not very clear, but in the engine casing, there are many empty spaces not occupied by grease. Also, consider that with heat, the grease tends to become liquid and leaves even more space
My wife and I have these on our bikes and ride them all over place.
Do you have the same kind of engine?
@@Ego.Reficio No, I should have specified that in my original post. We use the recycled beer can ones from China. They are very similar but the quality isn’t even close. They aren’t bad once you now what to address when you get them.
I understand. I’ve never had one of those made in China, but I think they’re still fun to use. How do you solve the problem of having the license plate and the insurance, in order to move on the street?
@@Ego.Reficio in my state( Ma. ) As long as the engine is under 50 cc, it’s considered a moped and doesn’t require registration or insurance. My engine is 66 cc but I have a sticker that says otherwise. They really are super fun and much cheaper than electric. Well, for now at least.
Great, so you can use it without problems!
Perfect job...
Excelente, didactico, Profesional. Un trabajo admirable
Thank you!
my comment is somewhat different, for the time period this engine is a well engineered piece of equipment.
simple yet efficient, we always thought Italian stuff was cheap trashy and nasty. now as an old man I look at this engine with different eyes.
Italian's did really well with what they had after the war, hats off to them.
А где запуск ?
You mean the continuous video?
@@Ego.Reficio Процесс работы двигателя после сборки
I’ll make another video where I’ll do a quick conservative restoration of the bike. I’ll mount the engine and test it.
The video will be released in early summer

разобрал-очистил-собрал. шедевр!
Thank you!
Thanks for sharing. This was fantastic.
Thank you instead!
Very good work,and amazing engine,greetings from Greece
