Also wanted to add: I love the lack of music and talking. Just a guy steadily rebuilding a motor and the sounds of his tools. Well done.

Reminds me of my childhood trying to keep my old wrecks working for at least another month - no special tools, cheap oils and grease, dirty rags dipped in petrol to clean everything, re-used the gaskets where possible. Nowadays people spend more time polishing their tools rather than actually doing anything with them. Keep up the good work with the tools and skills you have.

Hi again, I like your videos because you don't bore us by showing tedious details, you get on with the job and time-lapse is excellent for this. Ignore your critics, I don't see them posting stuff for scrutiny! Thanks for sharing and please continue showing your great videos (which may not impress everyone, but so what ?)

Incredible and very, very satisfying to watch. You have great skill and talent, thank you for uploading :)

The most hooked front sprocket ever and you put it back on !

[@louismorgan2679]

Thankyou so much man, I'm currently changing the main bearings and seals on my rxs100, seems to be a very similarly built engine so this helped alot. Cheers!

I did this once. It wouldn't run afterwards, but I did fashion a pretty decent boat anchor out of the leftover spacers, washers and gears.

Мастер просто красава молодец! Постоянно смотрю каждую видео на канале

[@robduc996]

Lovely relaxing video to watch. But for the benefit of anyone using this as a guide to rebuilding an engine: 1. Carefull where you're putting the yamabond. This can detach and end up in oil ways etc inside the engine. 2. Add a few drops of oil to the new piston and rings. Otherwise these will be totally dry when the engine is first started 3. Never ever use a screw driver to lock the clutch when tightening the shaft nut. Very lucky not to break the fingers off the clutch basket here.

[@andrewdwight3443]

I absolutelty agree with all three things you said, I have never seen an engine builder not put oil on a new two-stroke piston, he overdid the yamabond something fierce, and I was cringing at the screw driver, I also think he should have considered a new crank, and new basket, hub, pressure plate for the clutch. It was a really nice build but why go all the way and not replace some simple parts that could cause some major problems, metal shavings from the weak old clutch pieces will ruin an engine very quickly!

[@rposton919]

Lol...probably won't start.

[@CurtisTarwater]

Very nice work on the engine. One suggestion - since you're going to all the trouble to replace pistons, rings, bearings and seals why not spring for $10 worth of hex socket cap screws to finish off the engine rather than using all of the old mangled JIS screws. It will make for a beautiful addition and make servicing in the future much easier. Cheers!

[@stevothegreat]

That is right about replacing jis screws with hex socket cap screws. I had to grind several jis screws after being corroded to the engine body on several of old Honda's.

Just wear all the teeth off first..when chain spins on sprocket then change it..

[@jamesmegill]

It's so relaxing watching this vid😁

[@TS50ER]

Good job. If I had to critique; the screws on the stator plate should really have been replaced. That would have niggled me knowing that the next person to pull the engine may have a problem with the screwheads stripping.

[@tomjerry6529]

Great work, besides of missing mounting lube AND the base cylinder gasket ist in the wrong direction, blocking part of the transfer channel inlets. Might be worth 2hp or so. Cheers

[@TerraRoot]

That base gasket stressed me out when I saw it.

[@kadenburrus2821]

Just baught one of these bikes and it's my first experience with two stroke engines

[@SeshagiriRaoSunkara]

U guys are amazing...

[@tsclly2377]

Had a 250MX in the late '70's.. had to tear it down due to my brother stomping on the shifter (bent the arms) and it always needed a new ring.. just about the same thing as this 125.. and this was a real good contrast to the Honda.. so much simpler. Anyway..Kiddo.. you're a PRO at this.. the guy that whines 'torque wrench' is lost about 100 engines ago....

[@sicks6six]

Would like to see new stainless steel Allen bolts used on casings and new studs, nuts and bolts, 10/10

[@simonallan9941]

Yes I worked for a Tool&Die company with boxes of black high tensile allen cap screws/bolts, so all my mates bikes had them and they're awesome for never needing an impact driver not damaged screws and easy to carry the key with you 🤗.

[@mrjohhhnnnyyy5797]

Just one complaint - if the cylinder wasn't rebored, you made a big boo-boo by installing 3rd oversize piston to replace the old 2nd oversize piston. Cylinder doesn't wear in a perfect circle, you can't just slap a next size like that without boring out the jug.

[@fuchsi9148]

What al lack of love for engines. No oil used for assembly. The clutch almost looked like a used one. No quality bearings. Just hammering all together so you can put a shiny polished engine on display.

[@nicolasoliveira4903]

Two Stroke bro. No Oil

[@bb-ballistics1706]

@@nicolasoliveira4903 putting a little two stroke oil on the new piston and cylinder when assembling is always a good idea..

[@centurian318]

The dry needle and ball bearings was killing me, as well as the dry piston and bore. Was that ATF for the transmission???

[@CZ350tuner]

@@centurian318 Should have been EP80 or SP90 gear oil. I feel sorry for the gearbox and bearings. I've seen worst such as rebuilding a 2 stroke that the owner had run on 10-40W 4 stroke oil in the gearbox and for the crank lubrication. Worst still it had graphite (Shell Magnetec) so when the clutch started slipping despite being new and the crank journals started grinding & whining it was brought to me to fix. Ended up having to totally decontaminate and rebuild the engine. Why did he do it?? Someone down the pub / at work / one of his mates recommended it.

Hello, what is the medicine you use to shine? I would be glad if you tell me how to find it.

[@timkilgallon2098]

Thankyou I enjoyed this vid. No Crap. I would have liked to see how you held the clutch while you undid the center nut. I suspect a screw driver. And the fly wheel came off easy. I'm doing a DT125 at the moment, very similar engine. I see you put a gasket on the crank cases. And I would like to see how you set the Ignition timing. thanks Tim.

Torque wrench is not used by many mechanics around the world, but why didn't this guy use any lubricant during assembly.
