FULL Restoration & Test Honda CG125 ruclips.net/video/nuZ_bafNtvk/видео.htmlsi=C0lhwiQX-tyDYcms
Hey man. What did you use to clean the engine parts?
Am always amazed at how people can disassemble and reassemble an engine. Looks like sorcery to me.
Man look like assembling Alico pieces. 🗿💔
If you study the craft long enough and do hands on work, you'll figure it out, but itll be Greek during the learning process I'm sure
Its really not that bad. I did my first rebuild at 13. You just gotta kerp track of how things go together
I feel you broh 😂😂😂
This is a Honda CG 125 an everday motorcycle for millions of Pakistanis still in 2023 and still being produced in very large numbers.
Brazil too, but no longer produced
in Indonesia it is also no longer being produced, but many builders are rebuilding it,, on average they make the engine 200cc ++
@@bimauma yeeeah here too bro
How much is a new engine? We don't have them in the USA. If you find one from someone selling, it's very expensive. Those old Honda engines are very desirable.
@@riskybusiness3413 bro i dunno, here in brazil we can find a motorcycle in the state of the one in the video and still running for 900 reais that is 178 dollars, but a restored one is like 7.000 Reais, that is 1.373 dollars
Really amazing piece of work! Very impressive. Must say though that I was a little surprised that after going to all that work, you didn't grind the valve seats or change the piston rings.
Really enjoyed it though! 😀
Psh
Neither did he bore the cylinder
I know, you're right. But this is obviously not a real engine rebuild. It's more for fun and looks, like a museum display piece.
I was gonna say the same I was like why isn't he changing the piston rings
Yeah but he did smear some Bondo on it and sand it back off so there's that
It’s really nice to know that most bike engines are somewhat similar, so not only was I satisfied, but I also learned a lot watching this
Muy buen video artísticamente, desde una vista de un conocedor en mecánica, lo veo solo como una restauración estética, puedo apreciar muchos detalles que no son correctos, cómo por ejemplo, no cambios ningún rodamiento del motor que son muy importantes, no lo vi desarmar las válvulas para asentarlas, limpiarlas ni mucho menos regularlas cuando puso la torre de balancines, tampoco cambio los retenes que con más de 50 años ya no tienen la elasticidad para cumplir su función óptimamente.
Si me gustaron algunos detalles como la puesta a punto, el torque (ahunque solo le dió a la tapa de cilintros) y la fabricación de las empaquetaduras con papel bilumoide que por cierto le faltó la del filtro centrífugo.
En fin, puede que me equivoqué y alla echo esto fuera de camaras pero sería bueno tomar esto en cuenta para un siguiente video.
Yo creo que lo debe hacer, muchas cosas que restaura muestra como funcionan y siempre termina siendo de la mejor forma, muestra lo justo y necesario, ya que si muestra mas cosas de la restauracion, se hace muy largo y aburrido el video para la mayoria de gente
Tambien un detalle es que golpeo el cilindro, para bajarlo posiblemente rompiendo algun aro, lo digo como mecanico de motos...
Falto la arandela en el eje de arranque
@@santiagosalinas1107este video está hecho para la satisfacción y la relajación tanto de amantes de motores tanto los no tan amantes, el tiempo del vídeo no es relevante.
This brings back memories, I had one of these bikes for years, I rode one from North Wakes, to Cottingham, in Hull, for my part one and two training, did the full journey there on one tank, did my training and part one test, and all part two training, than went home on the Sunday. I passed my part two test shortly after. Happy times.
Só faltou funcionar ele , esse é um dos melhores motores produzidos pela Honda aqui no Brasil....
Sim meu amigo 🤜🏼🤛🏼🇧🇷🇧🇷🇧🇷
Pode crer... Eu ja ia comentar isso... achei meio estranho a montagem do pistão kkkkkkkkkk mas queria ver ele no fogo.
@@m16ma14mar11eli21 kkkkkkk fiquei pensando, esse aí vai ficar fumando,mas como esses motores aí são tanques de guerra,talvez nem fique
A Honda até o fim dos anos 90 era surreal
Só faltou colocar o retentor da mesa do magneto kk
In Brazil, the CG 125 OHV was in production from 1976 to 2008, being CG 125 at launch, in 1990, it was renamed CG 125 Today, receiving the CDI replacing the platinum in 1992 and also some improvements in the engine, in 1995 it passed to be called CG125 Titan, in 2000 Titan underwent a redesign of the motorcycle, receiving some improvements in internal parts and adoption of electric start, in 2005 it was renamed CG125 Fan, until the end of production of OHV engines in 2008 due to engine no longer meets the restrictions of Promot III. It was the best-selling motorcycle for 32 years. The CG 125 Fan continued to be manufactured from 2009, but with a completely different engine, derived from the CG150 Titan OHC, launched in 2004, the 2009 CG 125 OHC was nicknamed "Bufa".
It is still produced in Pakistan. I have one 2018 Model Cg125 OHV with same classic look with a bit changes
No wonder the reason these engines last forever. It's plain to see where the difference in comparison with the others engines are,
these things are still in production here in Pakistan, same old 70's design with little bit changes. i have a 2017 model.
Here in the Philippines theres the version called the "TMX125 Alpha" which is a OHC version of the old CG125, internally called the CCG125, it has alot of copycats around the country, especially the engine which is such a common sight in copycat motorcycle manufacturers here competing on which can offer the lowest price of tricycle use.
Still in production up to this day in Philippines
More of a deep cleaning than a resto!
Motor cg todavía se sigue fabricando por su mecánica fácil y confiabilidad..
Saludos 🇨🇴👋
Aqui no Brasil deixaram de fábrica mais ainda ar muito deles muito bom 👍
2t o 4t?
🥺🥺🥺 aca en México las descontinuaron desde el 2010 y se siguen echando mucho de menos esos motores brasileños, nada q ver los trastos d procedencia china q hoy nos venden para el trabajo q ya se les rompe el cuadro, los amortiguadores y los rines de rayos ademas d q el motor q no es tan duradero ni ahorrador de combustible, la linea cg125 y cg150 esas sí fueron y son motos de uso rudo, y por esto andan algo caras si buscas adquirir una usada 🥺🥺😔😔

Meu vô tem um desse essas moto e veia mais e boa
Deixam um melado de oleo onde param, mas se ir completando a moto dura mais tempo que o dono kkkkk
@@renandk4699iigual minha strada 200
o vagabundo montou com parafuso de phillips velho, alguns ta até espanado, estator zuado, só lavou mesmo. Vídeo de dar raiva
Tenho uma CG 1980. Demorei 2 anos para o restauro completo. Ficou espetacular!!!
Tôi cũng có 1 chiếc 1990
Except for honing the cylinder wall and new rings and grinding the valve seats, that was a flashback to my youth when I rebuilt an Mt 125. Nice work.
Un artista. Qué elegancia en el trabajo!!... 👏👏👏 BRAVO!!... PERFECT!!. 👍👍
Esse motor é um tanque de guerra. Tem uma durabilidade incrível.
Esse mecânico é um ótimo profissional, fez um trabalho impecável. Gostaria de vê o motor funcionando no final do vídeo ❤
o vagabundo montou com parafuso de phillips velho, alguns ta até espanando, estator ruim, só lavou mesmo. Ele é bom em lavar, agora de resto...
@@davidramos4784 vi parafusos com solda, os discos de embreagem deveriam ser substituidos, como o motor ja estava aberto as valvulas poderiam ser substituidas...
@@VictorOliveira-wi3zq o cara deve ganhar muito mais com os vídeos do quê consertando motos ksksk, ja parou pra pensar quê o foco e conteúdo? Vai vê ele nem vai usar isso uae , só ta restaurando justamente com as peças originais quê já tão no motor, agora fala quê um cara quê desmontar um motor todinho e monta de novo peça por peça não e um profissional, e ter um ego bem grande em
Isso sim é uma restauração de respeito. Mecânico faz tudo trabalho de qualidade respeita os mecânicos .
Another excellent restoration the only thing I would say maybe could have been different is to paint the Honda black to match the top cover tying it all together.
Possibly simple four-stroke engine arrangement and therefore so vital. Good job, congratulations!
Thank you for likes 😀.
It's a 2 stroke I think
@@AR15rules No, four stroke engine 😀.
@@ZygmuntKiliszewski most motorcycle engines are 2 stroke, and judging by the fact that there's only one piston, I think it might be 2 stroke
@@AR15rules why is he draining the oil out if it is two stroke hmm??
I can see why most people give up these projects, one look at all those parts and I would give up too. Persevere, this project's looking awesome!
Not that many parts that’s as simple as an engine comes
Simply magnificent! outstanding restoration, keep up the great work:). Esses motores em Durabilidade são campeões ️.
You never forget your 1st. First engine I ever rebult in 1983. So many memories 😊
I absolutely love these engines, I have a few clones of these and they are rock solid and cheap/easy to work on, no rattly timing chains and super reliable. Well done on this one, it looks super good after you restored it. Wrench on man!
u can import a new one from PAKISTAN , it still manufactures these old 1970s bikes. Would be extremely inexpensive bike 😅😃🤣🙃🤣
Look for LATAM motorbikes, brazil, arg, etc. Plenty of 125/150/190cc engines, 2 valves, 4 valves, carburated or FI, u name it👍
Motor totalmente restaurante e ficou novo 😊 ótimo trabalho nesse motor da Honda 125.
Fun to watch for sure. Thank you for taking us along.
Is there a specific reason why you chose not to replace all bearings, rings and some other wear-items while you already had invested this much time into disassembly?
its just all paint bearings are not that expensive butt its entertainment only.
we never heard it run first and after..
and it was complete not trash.the frame made it look terrible .
that motor was ok from the beginning ,frame made so too look bad .
entertainment only.
Work of art!!! Great Job.
Very nice restauration!
I would have loved to hear it run
A very reliable engine, very easy to troubleshoot and to maintain
I wonder if the frame and tires will be one video or split into two?🤔
Awesome job!!! ❤️❤️❤️👍🏻👍🏻👍🏻
I know nothing about cars but this is awesome love seeing an expert do their thing
I really would like it if you could start adding in what liquids your using, what color paint/primer. Etc. Just in 1 of the corners. THANK YOU IN ADVANCE
Very nice!. Too bad we didn't get to see it run.....
Наконец продолжения спасибо за такой длинный выпуск . Да ещë кажется что да, маленький двигатель и столько деталей ✊
жаль что не завел
Mecânico faz tudo trabalho de qualidade respeita os mecânicos . Possibly simple four-stroke engine arrangement and therefore so vital. Good job, congratulations!.
Made a very good video. Encouragement from Thailand.
Yes very cool 😎
Excelente trabalho.
I am super excited for final part please upload the final video it’s been so long and just waiting ❤❤❤❤
I am no expert but that engine looks brand new inside. When I was young I bought a motorcycle that was sitting outside for many years, managed to start it up and drove it for 2 years without changing anything, not even the oil, and sold it as it was for double the price. LOL. I would be so scared to put all those pieces back together. Great job!
Legendary little engine in its own right
I had a 71 Honda SL-125 that eventually had a 145cc powroll kit installed on it and before I did the kit on it i tried blowing it up to see just how tough the little 125 engine was and just held it WTFO for well over 2 minutes straight and nothing WTF that surprised the hell out of me thought for sure it would let loose after just a minute NOPE 🤣💪💪😎
Owned and raced alot of
Honda XR's AND CR 's and I'd have to say that those old air-cooled XR 's were damn near bullet proof ! Keep your oil/filter clean, air filter clean and a fresh plug every now n then and that engine will last
FOREVER 💪😎👍
excellent job. Keep making new videos my friend. excelente trabalho. Continue fazendo novos vídeos, meu amigo.
Restauração top! Mecânico profissional.
Very nice and helpful video. In this procedure, your should change Piston, Piston Rings, Carburetor internal parts, complete gasket kit, ball bearings with brand new parts. Thank you Sir.
Maybe he has checked clearances and pistone an Rings are ok
@@marcofrancioso6348 Dear Marco, When you put out piston with that's 2 types of rings from cylinder after several years of using them, they should change with brand new one because they (Rings) will deform after exiting from cylinder and maybe appear micro cracks on them.
I was also wondering why he didn't change the wear parts.
Most of these parts (gaskets, ball bearings etc.) are easily available and don't cost a fortune, but I'd strongly recommend to use a NOS piston (if necessary!) and piston rings, as aftermarket parts by my experiance often show low quality.
Dude this is literally what I’ve been looking for
It's incredible how this video doesn't seem to be 30 minutes long, I watched every second and I was so fascinated by the excellent work that I didn't even see the time pass. This video is a masterpiece
Nossa ficou 10 👏👏👏👏👏
You can still get a new one in the Philippines. Currently marketed as the TMX 125. Assembled at the Honda plant here from domestic and Chinese parts. There are also knockoffs marketed as Skygo, Rusi, MotorStar and others at varying levels of build quality and price but even the Honda badged machine is only around $1,000 USD.
Nice. In the UK these little pushrod motors were the CG125 - the various CB 125s were all overhead cam. The CG was marketed as a commuter bike and so lower priced. They appeared in 1976 and I had a '78 version. Not fast, but sipped petrol (100 miles per gallon was possible) and as long as you did regular oil changes, cleaned out the centrifugal oil filter and kept the points in good condition it would run like a slightly rattly clock. Mine was still doing that when I sold it with 72,000 miles on the clock. I went everywhere on that thing for years through college and then on the dole in Thatchers Britain no experience, no job. No job, no experience. Build quality and finish were excellent in the earlier ones and tolerances and specifications of materials spot on. Later ones were made in Brazil under licence and they has rumours of lower standards of quality control and materials specification. Never had one, but that carb is a later one with the plastic choke lever.
Not a highly-regarded bike over here, but well worth the effort of sorting one and using it as reliable everyday transport. A 12v conversion is worth it for better lights, but the 6v had direct generation ignition so if you could spin it over fast enough it would start and run with a flat battery.
The late ones like my W series CG ( year 2000) although twelve volts, also had direct generation ignition and also the same for the side light, headlight and tail light. The indicators and stop light were supplied from the battery. I suppose the variable voltage and low voltage while at tick over would adversely affect the flashers and stoplight. You mention lower quality - I had a brand new 1989 six volt one and also I still have a W series one made in Turkey or Brazil and it is very good indeed. I really admire the longevity and ability to take punishment through neglect that has been designed into the little pushrod engine. How clever also to design a valve system that only needs a single cam - shared by the inlet and exhaust valves. Fabulous little bikes. Change the oil every thousand miles and they will last for big mileages. So simple and hence reliable.
These are still made in pakistan till now I have a 2018 model and 2024 model just launched 1 month ago ...these are beast
This video was much interesting and perfect in restoration…If it included the full restoration of the bike that have been phenomenal. Anyways awesome😊👍🏻👍👌🏻
Isso sim é uma restauração de respeito
Extranho... uma restauração não se limita a limpar e pintar o velho motor, senäo a verificar com um manual do fabricante as medidas de cada componente, suas tolerâncias e a substituição daqueles que estiverem fora da medida, isso não passa de uma lavada de cara...
A mais, deveria ter feito funcionar para demostrar o resultado...
Você compraría esse motor?
Cara eu acho que ele fez a substituição de peças e reutilizou as que ainda tava em um bom estado, depois que ele mostra as pecas pintadas dava para ver que os redentores eram novos...
Esse cara do video tem varios outros em restauração de motores, acho que ele sabe bem oque ta fazendo, se fosse me confirmado que o motor esta bom para uso, compraria tranquilo.
You should get a parts washer. Some are self-contained, so need for plumbing.
Man it sounds great.
Extraordinary, fantastic
Respect !! Very nice work. And editing.
Yes very cool 😎
Excellent video/skills. I just noticed you didn't remove the crankshaft bearings' seals, which were out on original bearings for lubrication .
Even me I noticed that maybe the piston have been fixed back without o rings
Надеюсь поршень тоже тоже наждачной бумагой прошли.
А карбюратор главное помыть, он после этого точно будет работать. Так же как и старые слипшиеся диски сцепления. )))
Thank you very much. I cleaned my engine step by step watching your guide
Why did you go through all that and not pull the valves and lap them?
To get views.
Simply magnificent! outstanding restoration, keep up the great work:)
OMG! Beatiful I could only wish I could perfect such a rebuild.....Very Very Nice....Production was spot on....
I remember these 70s engines, extremely rugged and reliable.
It was a restoration, not a rebuild. That's why no metal parts were replaced. It was beautiful! I enjoyed watching every minute of it! I don't know why I find it so satisfying to watch!👍
Restauração top! Mecânico profissional.. Isso sim é uma restauração de respeito.
Good job.😊
Yes very cool 😎
I enjoyed it a lot and the cartoon was great. I have a Honda cdi 125, which is one of the generations after cg, and it has worked for about 30,000 km, and I think my clutch plate should be changed, but I really didn't want to open the door of my engine because it had not been opened before and it was the company's seal. But eventually I have to do it. Thanks again for your good video❤
Amazing Job 👏🏻
Respect!
Yes very cool 😎
A work of amazing precision, I really appreciate your work, man.🍻💪🏻
Yes very cool 😎
🤣
Restored to a clean paperweight, now a starting video
Nice job. Brought it back to life 👍
I love this little engine I used to have one. The 100 cc is also extremely reliable.
Good job
Yes very cool 😎
Excelente 🛵
Esse motor é das antigas, porém com uma boa reforma, ficar funcionando de boa 😊
Hello
Thank you very much and well done
This HONDA CG 125 engine model is very abundant in Iran
And 70% of the engines in Iran are of this model and I have one of these models
These engine models are very good engines and are compatible and efficient in all weather conditions
Thank you 👌🌹?
hootan Iran 🇮🇷
The guy just sanded valves in place. I'm done.
Brillante !!
Yes very cool 😎
Interesting engine.
Superb workmanship.
Inspiring video.
Thank you.
Excellent job. Please upload full Bike restoration viedo. Thanks
Yes very cool 😎
Will she start? nobody knows
Good job for someone to have a limited amount of the right equipment.
Yes very cool 😎
Brother you make it like new very good job.each and every thing looking good. Very satisfying video.👌👌👌👌👍👍👍👍
I get that you are trying to use minimum tools but hey we can all afford a parts washer :)
Bit surprised you didn’t take the valves out after demolishing everything else.
Still nice job, well done
A junta no velomolde é só por a junta encima de um E.v.a e por a carcaça encima e pressionar que ela molda certinho e só cortar dps
He just cleaned it.
I used to have a 2022 Chinese dual-sport with a 250cc engine. The engine was cloned off of this CG engine. It’s crazy how similar this engine and the one that was on the dual-sport. Everything from the internals of the cylinder head to the oil filter screen when I did oil changes and valve lash adjustments it’s all the same. 50 years apart and they still use the design since it’s built like a tank!💪
Very beautiful work!!!!!
You need about 5 gallons of Varsol and dip all those parts
Can you make your own video how then please
Wait your not going to fire it up?
Love them old Honda motors. They will run forever with proper maintenance
they will run forever even if the universe collapses these things will still be rolling around for some reason
Well done, did not appear to be anything mechanically wrong with engine; their so well made 👍
Those intake gaskets that came on it were just awesome 😂
😂
I think it's not a restoration but only cleaning
Now that it is clean, take it apart again and actually rebuild it, not just make it look better.
Amazing Restoration
Ficou novo muito bom 👍
i would have done a valve job
dude , you cleaned , bondo, and painted a already clean motor , no new bearings, no rebuild, at least do crank bearings, wrist pin , rings, quick couple of passes with honing bar, you had it apart, the parts are cheap and easy to install , and you really should get feeler gauges adjust the clearance on the rocker arms/ valves, not just torque it all back together, and for christmas sakes when you bolt down any cyl head always cris cross pattern =front left, rear right, front right, rear left,ect, if you gonna call it a full resto than do it right never put a top end back together without at least replacing the rings , and as many of the bearings as you can...........PS- bondo?????my man, bondo and spray paint ....just no.
He still gets views without doing these things.
and with smooth brained followers riding his lap all the way to the bank...hope the gave you a lollipop,...long ride back @@gordonwelcher9598
I am Indonesian ... This is remind me 40 years ago, my first motorcycle. Inherited from my father. Tough but reliable motor for daily use.
Why are these videos so satisfying?!
