Sheeesh I love that description for the flashing and tarnishing color. I just did my top end and I had the same exact coloration all over my piston and cylinder but the parts looked perfect and no wear on anything. I've been running maxima semi synthetic at 40:1 and it looked identical at 130 as well. Great video and thank you for giving me the peace of mind that my 250x is running as should even when getting very hot! EDIT - What billet clutch basket did you end up going with?
I read that the first & second gear from the WR400/426 models will fit in the YZ259X engine and they are a lower ratio than stock. Have you heard about this? Thanks
the color is caused by the blowdown from the rings, if you see this it means that the ring have worn out pretty quicky, next time to avoid it don't do the mix oil/gas precisely at like 2%, do it a bit more, like 2.5% or even 3% if you know that the bike is pushed to the limit
I'm in need of advice. I have a stock 02 YZ125 that is more than enough power for me, except for in certain instances. I'd love more torque, and I am considering a 250F. However, I'm wondering if a YZ250X with a fly wheel weight and apex XC head, be tamed down enough and be easy to ride like a 4 stroke or would I be better off with a 250F? I'm old and out of shape, and don't get to ride to often..so when I do I wanna enjoy it! Thanks!
Hello, I have a 2023 Yamaha YZ 250X, and the manual recommends a 30-1 mixture, what mixture do you recommend following your experience? I use Yamaha 2T oil
What octane pump gas should i run in my yz250? Should I be using lower octane or keep it at 92? MODS ONE BIKE ARE Apex xc head V force reeds 13oz FWW fmf Pipe and silencer I’m currently using 92 pump gas 50:1 dominator If you see this thanks for the help🤙🏽
So ive always rode a mx bike on track or trail. Getting away from the track and gonna do mostly trail riding. How does these yzx's models compare to a yz?
i had a yz250 race bike i bought an x a couple months ago and in all honesty just a little softer hit to the power band. but dont be mistaken its still a yz250 it will eat your lunch if your being stupid lol..I like it better than the race bike for trails i also have the billetron 38 carb. bikes awesome man no regrets here.
Yeah im gonna clean carb on the 06 250F and just ride it . If i ride it enough or have time to ride it then I'll consider dropping the cash. The 125x or 250x will definitely be the bike i want
250f is still an awesome bike man. Won't fault you for that. Go for the 250x I've rode both and if your use to a 250f you'll be better off with the 250x. If you have any questions don't hesitate to ask.
On the outside of the outer clutch basket in the video there is a scratch like mark that goes all the way around. Its where the kickstart gear is connected to the basket. Is this a machining mark or damage?
Had a customer with an 06 wide glide that blew up the clutch so bad a piece of it was acting like a drum break against the inner primary cover. Came in as a hard to start problem
Hmm..just bought a 2019 YZ250X.. is running it over 100hrs before a top end job "normal"? I was thinking in the 50-60 hr range but have heard people going longer. I also have never seen a broken clutch likbasket like that except for a guy who totally neglected his once.
Yeah I typically do 150-200 hours and things look great. Keep air filter clean, run 40:1 and don’t engine brake and you should be good unless you’re hitting the moto track at a high level pace often.
I'd say no as well. Just buy a ultrasonic cleaner big enough for your carb from harbor freight cheap and a bottle of pine sol. Use STRAIGHT PINE SOL NO WATER in the cleaner (the instructions will tell you u not too....it's fine...it's been done plenty). Throw your carb in there minus gaskets and It'll come out looking and working like new, and it's so easy a kid could do it. You can rinse with water after if you want but most just hang carb n let drip dry. Reinstall float n gaskets n hoses and your good to go. Cheap simple and you'll have the cleaner for life. Much love.
HI, Did you happen to do a compression test prior to the rebuild? at what engine hours did you start using CS2T in the 250? also what gearbox oil did you run prior to clutch basket failure? Thanks, Lucas
As stated in the video, I have ran dicks for the whole life of the bike. No compression test unfortunately….had to do the top end while traveling out west and was limited on tools.
Getting too hot that needle bearing is definitely war you can tell just by looking at it the needles were laying sideways instead of straight up and down so I don't know if that oil is very good for only having 130 hours on that
@@TheAyoubh from stock? Yes. Also from the XC. You get more torque on bottom with higher compression, but less over Rev. That’s why the SX isn’t always great. Extremely snappy down low but kills a lot of top end. MX I’ve found to be the best compromise. XC is still great, it just doesn’t give me the lug ability that I want. More compression means more force on the crank which is more torque.
So I recently got a older 03 YZ125 that went into a shop for a complete rebuild and had reciepts to show everything. Idk how many hours I’ve put on it, maybe a solid 40 of trail rides and casual harder riding always mixed at 32:1. With that being said I’m wanting to get a new piston just to have but idk what size to get?? I have the Athena head, and the bike still runs great, has great compression, and the plugs look amazing after each change. So im going to assume there’s going to possibly be usual to minimal wear on the internals, anyone have advise for me?
why do you change plugs?? and my yz had 40 hours on wiseco piston and amsoil oil and it was still in brand new spec . most likely could have done 100+ but i changed it for sale
@@paahtopro3950 I change my spark plug after every ride to further ensure my engine is running optimal for my riding conditions. Your spark plug is your #1 key to unlocking what is really going on with the top end of the motor.
@@daynefuxa4132 wth thats dumb. spark plug should only when fouled and it will run for vey long if youd around 50:1 oil ratio with good oil and a properly tuned carb.
I have numerous friends who've not had the best experience with them. Out of the 1000+ apex heads I've sold, there have been no more than 3 people I can think of who've had anything bad to say...and it was resolved and due to improper install or other factors haha.
@@BeRAD I would like to know what the difference is in those apex heads compared to a stock head. They do look good for sure. You know I just hear that they don't really change anything from stock and of course everybody's is the best whatever your selling. Make me an apex lover. Lol
@@rglce25 if anyone is claiming that they don’t change anything then they’re quite misinformed. It changes the squish as well as compression ratio. Send me an email and I’ll send over the info packet with the numbers.
@@BeRAD well this seems like it would make for a good video. I may have been thinking of the Slavens head. I have no doubt the apex is a solid product. It just looks the same as stock. I'll send email on Instagram dm.
@@Rugbyadam I kinda figured that. Just how big of a boy are ya? Maybe a yz 85 would get ya going. If you have never ridden a bike then yes get a ttr 125. Those are great
That’s what it was running before and I’ve never had a piston that polish and scratch free at this many hours. I never had a problem with dominator but this is showing to be a bit better performing when it comes to reliability! I have 2 video on my 125. Those were running dominator.
What do you mean? Because the clutch basket exploded? Fluke….it happens every so often but not “common” by any means. My last 250 went 300+ hours on the stock clutch. My 125 is at 230 hours and still rocking the stock basket and plates/discs. What else about the video shows it not being reliable? It was a single part that failed. No dirtbike will go without having to do something at some point.
How much they're charging for them bikes they can put a few hours extra work into it to make sure those baskets are made out of forged billet aluminum instead of cast that's ridiculous people are spending $12,000 for one of those bikes brand new and then they got to do that that's not right
Bang up video, dude. Good to learn more about 2 stroke oils from someone in the business. Would love to learn more.

Yes please in depth synthetic vs conventional oil video!
Hey Brad great video thanks also what clutch basket did you fit?
bilet
AMSOIL Dominator 50 to 1 racing oil leaves your piston and internals clean as hell
Clean in terms of coloring yes…but I also noticed more wear than with this Dicks CS2T. Dominator is what I ran previously. Watch my other videos.
Can you do a review on the RAD valve? Haven't seen many good reviews for it on the YZ
Hey BeRad, do you use any sort of aftermarket clutch perch or lever on the yz250x? It's too hard to pull with one finger! Awesome vid
When I saw your thumbnail play out I literally thought I was looking at a video I made.. you look a lot like me lol sweet channel!

Great video!
Hi Berad do you know of any upgrade stators for the yz 250? Or of what stator people are using from a Ducati road bike??
Just got a new subscriber! Yeeeee
How did the clutch plates look at the basket failure?
A few of them had chips in it. I replaced them. Hard to squeeze this much info into a video haha
the crazy thing about my buddy is he has a 21' yz 250 all stock and just did a top end at 250hrs and thats insane to me
If you give it enough oil, don’t back drive the motor, keep the air filter clean they can absolutely go that far or further!
@@BeRAD that’s so crazy my 21’ YZ 125 I do a top end every 100 hours but I abuse my bike like It ain’t mine😂
@@BeRAD what is back driving?
@@VampireJams i think motor braking
@@BeRAD Can you please elaborate on what back driving a motor is? Thanks
Hi Berad, Since the piston has minimal wear is it worth it to clean the carbon off and reuse it for more hours?
Nope. If I take the engine apart, it’s getting new parts! Would rather not do the work twice.
Would it be worth switching to a lectron or replacing my fcr carb on my 2005 crf450r
Are u having troubles with it?? Lectrons are awesome I'll say that much.
@@sevenmilewhite1407 I am having issues with my 17 year old fcr carb but that is due to it just needing to be cleaned

So if my clutch exploded more than likely there’s pieces in the gears!??😅
If you’re hard on it and or a very fast rider 32-1 if you’re a slower rider with synthetic oil mix 44 or 50-1
