Yamaha125 Engine restoration | Yamaha 125 Two stroke engine rebuild (1979)

[@curm1778]

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.

[@Pyrusia]

Absolute beautiful restoration, really love seeing engines being handled by the right people

[@rustybum2]

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 ?)

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!

[@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.

Looks like the kick starter spindle is completely shredded. Awesome polishing.

[@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.

You have earned a subscriber, your work and vids are great. :-)

[@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!

[@kadenburrus2821]

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

[@ydhalla25]

Great work, you have a great memory. I huge suggestion, please buy a Torque wrench. From Canada

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

[@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....

[@Ник-щ8у]

He drives the bearings of the crankshaft and transmission shafts into the crankcase cold, inserts fingers into the pistons by hand, smears everything that is sealed, misplaced the seals and gaskets, does not use a torque wrench, leaves the old fasteners ripped off ... Maximum "shine" for minimal money - here is his entire repair.

[@geethmensdis3758]

Good job bro

[@shabannawaz229]

Excellent work for the legend yamaha.

[@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.
