I haven't really had a dirt bike since high school up until last year. I bought a basket case 2001 yz125 I had a blast fixing it up and ripping around on it. So now I'm once again hooked on them. they sure are a lot of fun. Thanks guy's for the videos they really are great. Hope you get her running!
+Smightification lol I know you did. that's how I discovered you're Chanel I was searching Yamaha yz125 videos and stumbled across yours. About a year ago. Can't wait to see the finished yz426f :)
This helps me understand how to take it apart for sure because I also got a 2001 Yamaha yz426f but only difference is mine has a 50cc big bore kit so it a 476cc motor but I just recently sized the motor because I was going 75mph and the piston got red hot and the piston welded itself to the cylinder wall so I'll have to get a new motor either way
great video . I just finished my rebuild today mainly swapping parts being I had a spare engine. I might be able to answer a lot of questions if needed. my stock bottom end was a 02 yz426f I swapped it with a 01 yz426f. swing arm pivot bolt on the 02 was slightly bigger and did not fit. if all is well tomorrow and fires up ill post a vid. I bought the bike used and got a 5 minute ride out of it them toasted top and bottom end. I got the vid of on my channel of it blowing
Hello, I have a motorcycle of these but I want to eliminate that decompression system, how can I make it turn on like a normal motorcycle without having to touch that little handle
so i'm rebuilding a wr426 and the top end looked alright but 1 of the piston rings was seized on the piston. The oil filter had metal flakes in it but the crank doesn't have any kind of play in it and the top end isn't scratched up at all. is it worth just tossing back together and riding? i was told it just needed the top end rebuilt but then i noticed the metal shavings. it's just odd that nothing has any play or major scratches.
joe t if you have the tabs on your case to split it I probably would if I were you just to check and see what could be in there.. you don't just have metal shavings and no scratches also there might be some down in there that could cause damage
i want to split the cases and get into it more but i'm about to have surgery so it's gonna have to wait a while, i also need to order the tools for it all lol. do you know what tools i would need, any specific brands or sites you would suggest to order from? i have always wanted a wr426 so i'd prefer to get it running rather then sell it.
Yeah. . I wasn't too happy when I came home and dad gave me the news lol the guy ran it for a while it was already shot.. and made it worse. It would start and run in this condition it had a strong will to live
Yeah the guy lied to me when I bought it.. I knew he did but I wanted something to work on.. he said it started making noise after he changed the oil and he stopped riding..however his father in law said 2 seconds later " oh man even though it makes that noise it still rips he was flying up and down the road!" Lol so with no rod bearing he was still running it..
Smightification I see don’t you just hate it how people always bullshit instead of just being honest..we all come across it from time to time..did you end up rebuilding the engine..426 YZF where vicious on the track
@@donbrashsux yeah we rebuilt it it cost me more then I wanted it to haha I ended up spending 1300$ total on the bike then sold it for 1600 after it was rebuilt so i made some back but man that bike was amazing so much power and it just would come up in every gear! I have some videos of us riding it on my page

Good luck with taking it apart, hope it will run again

Hot clams has a auto decompression cam I believe
Smightification thanks 👍🏻👍🏻
Español ¿sabes cuanto disco de embrague lleva la moto yz426f yamaha modelo M 2001?
Hey, I have a 2001 yz426f 1st gear is blown, do u think I will have to split the case or can I do it from the side?
You have to split the case to get to the transmission
@@Smightification okay thanks, also this will be my first time rebuilding a 4stroke do you have any tips for the timing chain

I cried when I saw the condition of the engine!
Yeah. . I wasn't too happy when I came home and dad gave me the news lol the guy ran it for a while it was already shot.. and made it worse. It would start and run in this condition it had a strong will to live
Question... I have 2001 as well, the engine is froze, is it more likely too end or bottom end the issue?
Hard to say, this one the connecting rod bearing froze..
Well that's disappointing, look forward to knowing what the decision is going to be! =0)
Going to shop around for parts and see what I can do
Эти цилиндры гильзуются?
wow yeah that crank has seen better days.
for sure XD thanks for watching!
can you bore it out
You can but I'm not going to
new one or parting it out
gonna get a new jug
ok
Not to bad mate
We will get her all fixed up
I'm about to put $3000 in one of these, literally will be a new bike in the end so I don't have a problem with the investment
now days in 2021 you cant even touch a bike for $3k.. like a half decent bike its crazy!
You are absolutely right, same year of bike is going for 4000 and the new ones are 10k
il take that motor in a heartbeat
Lol I'm going to get it fixed up haha
+Smightification k time to see a real 4 smoker
Holy hell ..how do idiots just keep riding when the motor is telling you to stop..
Yeah the guy lied to me when I bought it..
