Restoration AM6 Engine - Complete Process 

Is it called restoration without replacing wear and tear parts such as bearing and oil seal?

Video shows that the engine was only washed not restored

Too bad for all the work, but reinstalling old bearings and seals is not possible. That has nothing to do with restoration.

This is not what I consider a restoration. This was a clean and paint job. No rebore & piston. You even reused the head haskets. It's prettier than before, but mechanically its unchanged. I would hire you in my shop as a blaster and painter before I hired you as a mechanic.

Yamaha DT50 is generally the name of the motorcycle that carries this engine whose reference is: AM6

The sand blasting, polishing and painting were nice, I would recommend doing that with your engine if you're tearing it apart fully anyway. The rest of the build however, I do not agree with and to everybody seeing this and never having done a rebuild like this before but considering doing one, I would not recommend at all doing what you see here. Reusing old seals and bearings after dousing them in brake cleaner and whatever leftovers remained in the crankcase is not at all sensible. I can only assume this build was done for someone who wanted to spend as little as possible or very little in general. When 'restoring' an engine like this certain aspects are of course a matter of personal taste, but replacing oil seals and bearings all around is no superfluous luxury. That piston was looking pretty rough too, and the cylinder wall will most likely have shown a similar wear pattern. I this particular case I would have done something about those as well. We didn't even see if you did maintenance on the carb or clutch. As I was watching I was wondering 'Why would he spray steel components with brake clean and not re-oil them immediately afterwards? That risks corrosion forming on them...' And would you look at that, all of the steel components got rust splotches on them at the point of assembly. Into the bargain, the crappy intake clamps and hose weren't even replaced. That stuff's like a few dollars or euros at your local hardware store, if you didn't have better ones already laying around. Nice end result to look at, but pretty poor technical refurbishment.

Wow engine looks brand new inside! Amazing how well they’re sealed

Nice vid, some remarks: Just hoping you’ve replaced bearings and seals off camera🙈 But why are the gears and ALL other internals covered in flashrust?! Would certainly not feel comfortable putting it back together like that. And why do you bother restoring wear items like the cilinder kit and airfilter? Would certainly never re-use that cheesy old airfilter🫣 And lastly, you should always tighten the crankcase bolts manually, and more important: evenly!! Goes a long way in not destroying the bearings.

nice job! also i'd recommend when you tighten down the case bolts you distribute equal pressure, ive accidentally snapped a crankcase bc I didnt tighten the bolts down in a certain pattern.

10 seconds in, I had to restart the video because I heard laughter and thought it was outside my window. Nonetheless, excellent work, as always!

It's just a cosmetic restoration. He left old bearings, old filter, old beaten up piston etc. Very bad example of restoration, made just to make a nicely looking engine, not nicely working one. Shame.

j'ai eu le temps de faire 4 Arrete cardiaque en 20 min de video, tres belle experience je vous en remercie

Его можно было не разбирать с такой ‘’реставрацией’’ просто помыть и помыть покрасить Хорошая работа 😂😂😂

красивый но не более кв без перебора поршень старый цилиндр тоже просто отмыт это что переборка? а звезда это же сюрекен он уже должен быть в утиль как и патрубок впускной который сгнил а его просто покрасили там пора новый делать. beautiful but no more than kv without busting the piston, the old cylinder is also just washed, is that a bulkhead? and the star is the same shureken, it should already be in the scrap as well as the inlet pipe that rotted and it was just painted there it's time to make a new one.

engine is in awesome condition from inside

Thank you for the excellent video and bringing back pleasant memories. These were remarkably reliable modern tech liquid cooled 2 stroke with automatic oil injection . You could runt hem all day at 80km/hr and not have a worry. Thank you Yamaha.

From a piece of crap to holy crap!!! ❤️❤️❤️👍🏻👍🏻👍🏻 Awesome job!!! Can’t wait to see Part 2!!!

The am6 engine is a good engine... But for me RK6 for life!!

LOOKIN' GOOD, NICE WORK...

Never seen a AM6 engine use mid crank casing gasket

Hey by the way I would not use that air filter because I have had experience with them before and they don’t filter sand or dirt they do flow good but the flow to good but good job it looks really good for what it was.

surface rust looks good on the gearbox

this video reminded me something, do not judge on appearance

I usually let my parts soak in the parts washer while I order new parts to (restore)!

just painting and cleaning! replace seals and bearings??????

That's a new engine with exterior dirt

He could at least have replaced the piston, given its condition I'm sure it is blocked

no replacement of the cylinder? or pistons etc.??

can you add the name of the parts please in your next videos, i like the method, thanks

could have washed the engine on the outside first before disassembling it.

Nice video. I wonder why the port on the carb next to the ports for pre heat water was plugged off with a screw? Is that supposed to be plugged as well?

Only estetic restauration😂😂😂

Normalement un am6 ne doit pas avoir de joint entre les carters moteur, c’est pas fait pour, et il manque le contre écrou du plateau Presseur, encore pas mal de chose à dire mais flemme d’écrire

ouais pas mal pas mal

Am6 engine, easy to work on and very powerful with some performance parts such as 100cc 2fast 😈

The engine is not build by yahama, it may come from a yahama but its built and provided by minarelli. (minarelli am6).

Добрый день наконец новый выпуск 🔥

someone buy this guy a jetwasher jeezuz christ

Lots of effort, and done nicely, but some parts with wear should have been replaced... What you did you did nice, but at this stage some parts are better to be replaced not only cleaned. Also if you want to avoid the parts from inside to rusat, after cleaning them put some oil on. (And I recommend for the cleaning diesel oil, and no water. It also helps to prevent rust, and cheap.) But please replace that sprocket, its really the end of its life... :D

head gasket go brrrrr, it will not last a day

Да он внутри как новый выроботки почти нет, поменял сальники и уплотнители и пробегает ещё). Вот японцы технологично делают, продуманная конструкция. Один недостаток это патрубоки из карбюратора к лепестковому клапану лучше цельным такие детали делать проблем с подачей топлива не будет и мельше деталей.

Nice video! Small tip: If you bolt or clamp down the engine during disassembly, the video becomes more pleasant to watch.

Bueno, tanto trabajar en el motor, para dejar rodamientos viejos y poner una junta entre los semi cárter, este motor no lleva junta sino pasta de juntas. Pero para disfrutar de un vídeo de "restauración" ha estado bien 👌🏿

Top top a galera do brasil curte seus videos

What's that liquid you clean the crankcases with at 6:00?

how do we know if the engine works ? 😋

working on an engine wearing a hoodie with strings is a big no no. My chin learnt this the hard way

What product did you use for clean the paint?

In Austria we call it "purer Pfusch!" ig de clutch is wrong and is that paper tape as sealing?

Pourquoi remonter un piston dans cet état avec ses segments ?? pignon de sortie de boite hs aussi et la boite à clapets et j'en passe..... bref....je serai curieux de le voir passer au banc après la "restoration"....

For your info engine is called minarelli AM6, Im running exact same engine and exact same condition as this and it doesnt need a restoration tbh

Washing the paper air filter???? That was my limit...Find another occupation dude, thats not for you...

Qual o tipo de tinta spray esse rapaz usa? queria pintar o motor da minha moto tambem.

Ahhhyy, that really hurt in the mechanic part of my brain... 🤯

OMG the Oseal condition for head And adjust gasket paper on case

Great restoration. That piece is a beautiful 😄😄

Restauration without replacing any part with new one

Ça remonte des pièces usé en fait ?? Ou est la restauration la dedans à part nettoyage et peinture ???

Hoće li biti nastavak sklapanja krosera ili samo motor

Amazing

Awan subscriber na hahahahaja

could you tell what foam this is to remove the rust?

No bearing changes or hone ?

Am5/6 mineral right.? Have the same

Opening from the piston rings are facing to the exhaust. That won´t last long.

Qlq sait ce qu'il utilise pour faire partir la peinture

И стоило так из-за двухтактника заморачиваться...

can you restore 125cc Lifan ????

L’embrayage a mal été monté il est bon à démonter pareil pour les roulements 🥱

Cylinder do szlifu, tłok, pierścienie, sfozeń i łożysko sfożnia do wymiany,zębatka od napędu do wymiany

nice video but you didn't build the block correctly the head gasket is not reusable if in that state and the clutch lid wasn't put on in the correct direction. the way you blocked the flywheel by the crank is just wrong. the intake manifold is so old that you should not reuse it and you did not properly install the case

That headgasket was totally blown, coolant and exhaust gases will mix. There is no sense to do this job without replacing all the seals and bearings at the same time

Ahhh, I get it now. Reman only means washed and repainted. R&R: remove and repaint. Always wondered what that meant.

imagine doing an restoration and ending up with rustier internals than before. i would also tighten that cilinderhead a bit more, if youn want it to break, better do it good

The good Old am6 engine. My absolute favorite engine ever produced

This is called cleaning not restoration. What tolerances where checked? What play was in the crank? Was it out of balance? Why were the rings not replaced etc etc etc.

What years and country were these sold in?

ржавые звёзды кпп👌👍

Isn't the carborator hose very crooked?

sealants,bearings ?

Yamaha.aprilia.rieju y alguna marca mas. usaba ese motor.... minarelli 😂❤

Bro thats just a dirty new am6😂

Pleased make a Honda CX 500 v 2 engine🙏🙏🙏🙏🙏🙏🙏

what to use to clean the engine? I mean this liquid

Tu as oublier la rondelle de calage sur le barillet et ont ne met pas de joint intercarter sur am6 mais pattes à joint dirko

Мамкин рестовратор 😅

Veramente questo ha lasciato i paraoli e i cuscinetti senza cambiarli? Robe da matti

I would highly recommend using muriatic acid to remove rust and corrosion

Pq ngm fala que esses vídeos são tipo asmr dele trabalhando nisso ? Os barulhos e tals

Does it work?

ne jamais mettre de joint en papier entre les deux demi Carter c’est de la Pâte à joint , rien d’autre car il faut respecter un certain écart entre la boîte de vitesse et les carter. Là il y a trop d’écart, tes vitesses vont faire que sauter.

Todo el video mirando para que al final no lo arranque... en fin

Minarelli am6 put a tpr 86 tuning kit on it

Будни перекупа

crankcase locator bushings?

Od kiedy w am6 idzie uszczelka pomiędzy kartery? A oto drogi Panie nie idzie Powierzchnia jest tak spasowana ze nie potrzeba uszczelki i kładziemy masę uszczelniającą

Why not change worn parts?

what product do you use to clean the block?

hell yeah, grease the transmission to death, but never ever put a singel drop of oil anywhere to the piston, this would damage the 2stroke, imagine it was lubed at its first run.

first start?
