Tiene el manual mecanico
Fuck man now you show this i already done cut mine off lol fuck it
God, that is a jewel of a motor. Up there with the CBX and the gear cam VFR.
I reassembled my rear mstr cyl but it will not draw from the reservoir. Any suggestions?
Ensure the seals are oriented the correct way. And some form of vacuum bleeding tool can help to get the filling started. Good luck 🤞
engine 4L1 = RD250LC
engine 4L1 = RD250LC
How long did that take?
Not sure, around 1.5 hours I would guess.
some of rd have 4 shifter forks, is there another model?
Sorry, I don't know of any model with 4 forks. Maybe older RD air cooled model?
Amazing Job done, Congrats.
Thanks!
Доброго дня хороший человек! В какую сумму обошолся ремонт вместе с запчастями? И сколько у вас стоит перебрать двигатель (работа)?
Lovely work
Thanks for your comment!
Wow! For most people wanting to get a case repaired, the answer from most commercial shops would be "no". And if they did, the costs would be prohibitive. This is truly an example of ingenuity and craftsmanship at its finest. Nice job and great to see another bike saved from the parts bin.
Thanks for your comment Ken!
Nothing short of amazing. That’s how you save unattainable parts.
Thanks for your comment!
Yamaha 4L1 is not a 350 LC....its a 250 LC
You are correct. The crankcases left the factory in a 250.
Seems like you know what you are doing.
Thanks for your comment! I am just trying :)
Exelente contenido muy buena calidad de edicion y sobretodo gran trabajo estoy a la espera del proximo capitulo un saludo... Excellent content, very good editing quality and above all great work, I am waiting for the next chapter, greetings
Tengo una 1995 y la segunda cuando aceleró se brinca como si fueran los dientes que puede ser ya cambie cadena piñon y sigue igual
Hi, maybe damaged 2nd gear pinions. The problem is you have to split the cases to check. It also might be the selection locking mechanism behind the clutch. Maybe check that first.
It needed the airbox to run correctly without it it's lean
Yeah, it doesn't run well without.
Столько времени и сил и средств, а колеса разные!!!! У тебя нет вкуса, надо было еще заморочиться на одинаковые, так и смотрится и едет лучше!!!!!
Sorry, I don't understand what you try to mean about the wheels. Please explain?
Putting back together what thought blown head gasket. Gasket not blow and just tightening the head bolts would of probably resolved. Big job, waste of time. It's was ten times easier putting a entire engine in in one piece, then this tear down. Waste of time. My recommendation is instead of tear down, just replace engine as a whole.
Yes, replacing the engine is much faster and can be cheaper. You just have to be sure the engine you get is in good condition. For me it was also as hobby so I don't mind spending the time.
@@jh-tech5546 I may have to replace. Probably get back together enough to junk.
what's the size on the gap gauge?
The spec is between 0,11 mm and 0,20mm for intake and between 0,21 and 0,30 for exhaust. Is that answering your question?
I made a deal today for one of these bikes. Hopefully, it will be my next week. I felt in love with this bike the minute I saw it.
Nice. Thanks for sharing.
How long di it actually take to assemble?
Not sure, I guess one or two hours.
@@jh-tech5546 Very cool video mate, thank you. A very long time ago I did two seasons of racing on a 350LC. It was a magical experience. Those were good days.
Zen Master! 🙏
Thank you!
Вы, случайно, не забыли поставить отбойник/буфер на шток аммортизатора? А так, отличная работа👍.
<Translated: Did you happen to remember to put a bump stop/buffer on the shock absorber rod? Well, great job.> Thank you. Yes for a short moment. I don't think there is one on from the factory so I left it like that. But I think in case this shock absorber doesn't work well in the future it should be replaced.
Parabéns pelo capricho
Really nice job, is there an opportunity to contact you and ask something specific about the hoses from the carbonator and fuel tank ?
Hi, feel free to ask here, maybe it is interesting for others too. Or you can mail me, mail (see channel details).
Please talk.
I just picked up a blue red and white 85. The only available graphic kit is the red and white like this one, which I think looks way better. Question is, is the red a slight metallic or pearl or just a bright red?
The red is a two stage metallic or pearl. To be honest I don't know the difference between the two. It is not a bright red. I got a decal kit from The Image Works in the UK but as you can see mine is a hybrid. It is a 87 with the 85 front fairing so I could not use the decals on the rear.
@@jh-tech5546 Ok thanks. Im a body paint guy. It must be the same color as the fender on mine then.
@@theoriginalmungaman The color is called Stormy Red and the white is Sliky White
Incredible work you do! You are a craftsman ! Inspirational stuff right there
Thank you! Appreciate it. The same can be said for you man. I like your video's too. They inspire me too. The GSX-R is going to look great.
You keep inspiring me dude! Question: Do you sell these after you're done restoring them? Or are you keeping them for your own collection? Either way, it's really cool.
Thanks for the comment. For now I still have all the bikes. And would like to keep them in my collection if possible. I won't be riding this one I think. But I have restored it ready to ride.
Encore une fois de plus une belle vidéo très instructive....Great job !!!!
Merci!
Wow!! Great job, it is looking amazing. Thanks for the videos on this bike
Thank you!
Wow!! It's like new. Great job. I can't wait to hear this thing running. I noticed so many similarities with the FZR1000 again.
Thanks Ken. I am really happy with the end result. The fairings have not been restored apart from repairing some cracks but no paint job. So it still has some scratches and small cracks here and there but I will leave it for now. Yes, FZ, FZR and YZF 750 an 1000 (Thunderace) have a lot in common.
@@jh-tech5546 From the videos, you can't see any flaws in the panels whatsoever. Can't wait to hear it run and to see you riding it!!
I’m looking forward to hearing her run. Great job.
Thank you! Me too :)
Very nice job. Roughly how many hours did it take to re-assemble the bike?
Thank you! Good question. I didn't do any tracking of time but was curious too. So I took all the episodes at real speed and in total it takes 2 hours and 43 minutes. Of course that is assuming all the parts and tools are ready to grab. And also spending lots of time searching for the right bolt or nut on each component.
i wish i could do the same to mine :)
TOP
Thanks!
Esse projeto está ficando top de mais 😃
Put the piston pin circlip in wrong but pretty close
Great video! I have a 1984 XT600 that I love, but it has almost 50,000 miles on it now and is beginning to leak oil from what looks like the head gasket. Is it possible to replace the top end gaskets without removing the engine? Thanks!
Thanks for the comment. I did not have the engine in the frame but what I can see from this video it is possible: czcams.com/video/2g-hGK5K7Gg/video.html
BRAVO!!!! Beau travail et merci pour le partage et le montage
Merci!
Where is a good source for good crimps & connectors?
When he opened up the packet for them, there was an email address on the packet. I didn’t make a note of it, but it was clearly visible.
In the UK, Vehicle Wiring Products for generic crimps, etc. For ones specific to bikes (such as the odd coloured ones used on Yamahas) try Kojaycat. The ones used here appear to have come from Yambits
Thanks for the info. The ones I used are from YAMBITS indeed. I don't know if it is good quality but it seems to be OK. Time will tell.
@@jh-tech5546 , Yambits are well established and reputable so I wouldn't worry about their quality.
Getting close!! Your timing for the riding season is perfect :o)
Yes, getting close. Still have to fire it up. I will not be riding this one. Too clean :)
Hello sir ! How do you do to start your restoration after me and finish before me ? 😅 I love your projects ! You're so meticulous and your bikes shine like the Sun ! They look like new ! 0km to the odometer 😉 Otherwise, my project is a ninja, a Kawasaki ZX-10 from 1988.
Thanks for the comment. I jsut do step after step :) Wen I don't feel like wanting to work on it I just do a small simple thing and so it still progress.
So close to the finish. Thx.
And so close to the first startup 😂
I got almost done. The caps on the lifters got scrambled and put in a different order. So, I heard I have to feeler gauge something and adjust? How? What? Last phase of getting back together.
I assume you mean adjusting the valve clearances. You can check a video on the YZF 750 I posted recently or you can find many info online. Good luck.
@2:23 thank f*** that music stopped
Be honest...did you had some emotions and anxiety for the first start????even if you know you did everything by the book,i still get shivers when i first start the engines after ive been inside of them...😅
Sure, first start is always exciting :)
