how to rebuild Yamaha YZ125 2-stroke dirt bike engine 
Авто/Мото
You said to come watch so here I am. 63 yr old intends to build his ultimate lightweight motobike. As light as possible, as much power as possible. Your video gives me alot to now go off of thanks.
Very cool,i have been building 2t,s for over 30 years and your mechanic is excellent.You turned me on to some new music also that I put on my Spotify to listen to in shop working on bikes.
appreciate the feedback Jeff, glad you like the music too!
Nice job! Motor looks awesome! Great video, as they always are!
thanks man!
That engine looks really good, I like the color combo!
thanks man, glad you like it!
Finally, Rado, I'm an old man and I didn't think I'd live long enough to see it go together.
hahaha, you are so funny Tom! I will hurry up now, keeping you in mind ;)
@@dirtniron Hey Rado - I love the music that you use in your uploads.....could you let us know what it is and who puts it out? Have a nice Christmas. P.S. I feel bad for those in Ukraine after what those Soviet bastards did to my native home. I wish I was a young man..........
Tom, all the songs are from Michael Shynes he is less known artist but I really love his songs and they are not expensive to get for the videos. www.youtube.com/@michaelshynesmusic
Yea, I feel you about Ukraine situation.. I used to live in Kiev for some time and still have a lot of friends there..
@@dirtniron Thanks for the info. I wish we could somehow wipe the scourge of the Soviets out of our lives or, at least, our countries. Seems Ukrainian president very brave man; hope he comes thru this alive. My mother is Polish and between Germany and Russia, they've really raised hell with Poland as well. Hope your friends OK. I was active in boxing and met one of the Klitschko brothers and also Lomachenko. I know Klitschko has gone back in-country to fight Russians.
Great video.
Brad is the man!!
thanks bros, he is for sure!
Looks good! This makes me want to get my 125 back together like right now 😂
go for it Brett! ;)
Engine looks great, I’m excited to see how it performs with the 134 .
thanks man, me too! It should be pretty noticeable difference. Hoping to race 2023 2 stroke world championship on it ;)

Yok Tobat Kawan Dan Jangan Lupa Sholat Dan Sholawat😁😀😊😊😊😊😊
Looking good Rado !! 😁👍
thanks Dave, appreciate it!
Awesome work
thanks Juan, glad you like it!
Rado, No wonder you have so many subscribers!! Cup of coffee along with good music and tech build video was very mellow and enjoyable start of my day. I'm getting ready to ride and peel miles off my beast (Super Tenere) this morning. What a contrast to the 125!! LOL
Right on Ollie, glad you enjoy the video. I wouldn’t mind to peel some miles on Super Tenere too 😉
It almost looks like this guy knows what he’s doing!
yep thats right!
Indeed. Except he's not wearing gloves. Repetitive contact with all those chemicals is a fast track to cancer. Plus he'll probably get much more frequent flus with his body having to express that crap out periodically.

I am not sure about that maybe if he finds a bigger hammer
That's awesome buddy even when my Yamaha Dream bike was in a million peaces never give up easier said than done
thanks Gordon, best feeling once the bike starts coming together
Clean build
thanks bro!
Very cool! Was that a special box wrench about 19 min. into the video, that you used with the torque wrench or vice versa?
Any tips on what it could be when your two stroke seizes while riding then the kickstart completely locks up? Ive took the head and cylinder off, piston and cylinder seem fine no seizure in the head but i have no idea where to look next😢
Great job.
thanks bro!
What is the oil you use to lube the cylinder and piston ?
Great job 👏
thanks Marco, glad you like it!
@@dirtniron Your work and attention to detail is fabulous, keep up the good work and great content
Appreciate it Marco👍
Great job! Congratulations!
The engine is beautiful!
I love the gray on the cylinder head and the clutch housing! If it’s cerakote I’d like to know the reference
Thank you Michel de France
hey man, glad you like it! Yes it is cerakote, tungsten color.
Que torque llevan las tuercas de la cabeza y el cilindro?
I just picked up a shiny new '23 YZ125X and plan to install a Rekluse TorqDrive clutch pack asap. I understand replacing a worn clutch basket but is there any performance advantage to an aftermarket basket over a stock one at this point? Was there any particular reason for your choice of a Wiseco basket over the Rekluse? Inquiring minds need to know.
hi, I would get full rekluse setup but they dont make basket for my old 2001 YZ125. The clutch pack is really good, more durable and stronger than stock, plus it comes with those metal sleeves so it actually protects your stock basket and it lasts much longer. My old basket was notched out badly. Wiseco was one of few companies who made tough billet basket for my bike, plus they have great quality stuff so I got their basket. I think you are fine with stock basket and rekluse torqDrive clutch pack, unless you are going to really abuse that clutch so maybe better upgrade to billet one. Rekluse has super durable clutch for "abusers" that comes with everything, checkout this video for good info about their stuff ruclips.net/video/-3A4Sy-qlyc/видео.html
@@dirtniron Thanks for the reply. I guess that would make me an unregistered abuser.
Really enjoy your vids....new sub!!! Question....I have a new 2023 KTM SX-F 350 and the manual calls for 10W-50 and I don't see that Rotella sells it. Can I use a different weight oil other than 10W-50?
Thanks man. We use that oil on latest models with no problems at all. If its my bike i would run rotella in it and save money for gas and tires. Its up to you tho. Take care
@@dirtniron So, what weights are acceptable to run in the new SX-F 350? I can run 10W-40 or 10W-50 or 15W-50 or 20W-50? I get confused regarding the weights. I just know the KTM manual says 10W-50. I assume it has to be synthetic, correct? I greatly appreciate all the help!!!
How do I see what music was in this video?
Dirt and "Iron"? I mean, yeah there's some iron in there among all the Aluminum, Magnesium, and various alloys made up of the two. Sure, a lotta internals like tranny shafts, gears, forks, shift drum/rotor and such are ferrous alloys... so yeah, there's some iron,... just questionable as to whether it's a sufficient amount to warrant a name/moniker. At any rate, it's obvious you've turned quite a few wrenches, and for more than a time or two,... you're sharp bro. You're good!
What is that cover called that you guys put on at 19:02
This engine is so beautiful!!!
thanks Drago, appreciate it!
@@dirtniron Thanks Rado 😀
i have the question, i have yz125 94, what crankshaft it’s compatibility for mi dirk bike
I am not sure, sorry.. you need to do a parts number comparison
So you mean to tell me that I could rebuild a 2 stroke in a weekend? HELL YEAH
What is the engine mileage per litre
I enjoy your channel, hopefully next time you will re build an engine yourself
what would Brad do then? ;)
Let’s here in sing, send, rip👍🤷🏽♂️
Where can i get all these parts?
you can get them directly from the companies websites, wiseco, prox, rekluse, etc
what is that white liquid at 14:18? 😢
Need some 125 or 250 builds
great build , looks so fresh. horrible music but thats ok
send me a list on not horrible copyright free songs for me next video, I would really appreciate that ;)
How much was the kit? The motor came out amazing and I really want to try a big bore kit on a 125 for the local track. Keep up the amazing content and thanks for sharing 👍
I am not exactly sure how much, it depends what exactly you need him to do. Get in touch with Tom he is very responsive and can take care of you. morganracingengines.com/
torque range tool is that expensive in America lol
AAM - American Association of Mechanics gets their best mechanics elbows calibrated annually, Brad is one of them. You guys don't get that?
Great video. Go easy on the music next time.
Bible thumper music sounds like a copy of a copy of a copy. Better to have nothing. Silence is golden
ok..

So so so much stuff remains unclear, skipped soooo many parts and important details. Thanks for the guide though, but this isn’t a good one. Any small details I had to google myself. Not that useful
I can’t believe how much money the average Joe wastes on aftermarket junk for dirt bikes. I’m in the wrong profession
This music so painful. Difficult make threw the video.
Probably a good video but I can’t get past the crap music.
