This guy needs to blow up, his videos are very descriptive and actually teaches you stuff while still having a joke here and there. Definitely subscribing to this legend. Came to watch how to repack a 2 stroke silencer now on my 5th video. Definitely deserves more followers for how much effort be much put in these videos.
Hey Riley ,I truely appreciate you taking the time to watch ,comment and subscribe.Thats the elusive trifecta that channels strive for and rarely find . You absolutely made my day with your kind words . Cheers to you good sir !
Agree 100%. His instructions help me out of a very tight spot. Play Yamaha YZ250 power valve I was working on had a very serious problem. And his video helped immensely.
My small valves won’t open all the way, I’ve flipped the shaft around and tried to adjust play but it just won’t open. I don’t know what’s wrong. Both small valves will go until the small curve in the lift pin guide but won’t go past the curve part? Any ideas?
Best video I have ever seen on yz pv assembly ..second best is not even close
@@CraigSteinman-zt3vu Hey Craig I have to thank you very much for such a great comment. I truly appreciate you taking the time to watch and respond so positively. Cheers to you good sir 🍺
Alot of the mechanical videos try their best to show how to do something, but they sometimes miss a step or they have done it so long, that they can't think like a person that is new to the subject. This guy is one of the best in the world in my opinion. I own a YZ250 and this guy has saved me thousands (Plural). from top end rebuild to carb rebuild to understanding the hows and whys. Even the small shortcuts, like pre assembling the link lever with the 2 springs, saving you a master headache later during re assembly of the power valve
.. Incredible , I bet dirt bike mechanics lose business cause of how good this guy is lol. If I had is address I'd send him a Christmas card.
Oh Jeez man ,your comments have to be some of the highest praise I've ever received. I certainly don't feel like I deserve it .There's lots of channels out there putting out much better stuff than mine .Having said that It's my pleasure to help you and others in any way I can .You made my day knowing that you were able to work on your bike with confidence and hopefully enjoy many many hours of riding with your friends, cause really that's what it's all about. Cheers 🍻 my friend and ride safe 👍
Best one on YZ powervalve install I have seen yet. I have a feeling I'm gonna need more help on other problems I have with this beast so I subbed. Thanks for your time making this great content.
Hi Mike Thanks very much for watching and actually taking the time to comment so kindly .Also ,the fact that you subscribed is fantastic I truly appreciate it ,thank you . The YZ 250's are such a fun bike to ride and great to work on so hopefully I can live up to your expectations with more relivant content ahead .Cheers .
And the Oscar award for the best how-to-video goes to TRyan. Awesome video, now i have to redo my power valve. It sounds very loud after a top end rebuilt. Thanks.
Ha ha ...thanks man I really appreciate your great comment. It means alot that you liked it and actually took the time to comment so very kindly. Cheers to you good sir 🍻
You make me feel like I can build a bike and that means something because I definitely can't. Great video, and great presentation. I can tell you put a lot of work into this, but you make it look so easy!
Hey thanks very much Andrew .I really appreciate you taking the time to watch my feeble efforts. I know you are a wildly busy guy so every moment counts .Also thanks very much for taking the time to comment. It means a lot ,cheers, my friend
Good job man! Makes assembling a breeze! Cheers from Montreal
Hey Martin ,thank you very much for the great comment. I genuinely appreciate you taking time to respond. Glad the video helped you, too.Cheers my friend
I just fixed my 2003 yz250 power valve just minutes ago from using this instructional video. It all started when I removed the cover from the power valve assembly. I discovered one of the link rod's screws had came out - and somehow its threads were chewed up(?). And the washer? It had migrated down the passageway to the outer end of smaller power valve - LOL, standing up on edge, looking like it belonged there.... Cleaned all items, added some oil to all parts, put it back together with two fresh screws, secured with blue loctite. Yeah, a real-world fix. So truly, thank you again.
Hey man, that's fantastic! .I'm legitimately happy for you to have been able to resolve the issue based on some of the intel.from.my video .That's exactly what it's all about .Thanks very much for taking the time to let me know ,you made my day .Cheers and safe riding ahead .
@@TRyanLearnBikes Damn. I really don't like to use lock tight on screws. But I think I will change my mind for these. :)
I am the same ,locktite has its place but I typically use it spareingly. But I also had some loose bits in the power valve and figured I should make sure that does'nt happen again before it makes a real mess of things .Thanks for the great comment @@EarthSurferUSA
These videos will blow up, entertaining, informative and short.
Thank you very much .Your kind comment made my day and gives me motivation to try'an create more videos .Cheers my friend
Awesome video! Thanks for this, saved my bacon. 🤙
My pleasure Arnold .I'm glad it was of some help .Thanks for taking the time to watch and leave such a great comment. Cheers 🍻
Man. I can’t stress this enough. Your editing is amazing. I will never be at this level of editing. The information is perfect. Damn great job. Damn great.
Jeez man ,thanks very much .Your comments carry a lot of weight because you actually understand what it takes to wear all of the hats required to play the CZcams game. It makes me ask the question, why do we put the time and effort into making video's .I'm legitimately curious to hear your answer. You have a lot of subs and what looks to be a growing channel. What is your motivation? What's the end goal?
@@TRyanLearnBikes appreciate that.! To answer your question it’s 2 parts.
1. I always searched CZcams when I needed help. I would find a video that seemed to cover all bases. And then when I got in to the job, I found out all the hard parts were skipped. Or actual angles that were helpful were not shown. I hated they made it look easy when it was actually not. So I wanted real information. I wanted to show someone what it actually took to accomplish a job from start to finish. All parts. Hard parts included. Real truth.
2. I love it. I always wanted to be an actor as a kid. Now I get to write, star, produce and create all my own stuff. Whatever I want. Guns, cars, family stuff, bikes, whatever I want. My way. I film family vacations, put them on CZcams, and set them to private so they can be watched forever. It’s an opportunity to capture and catalog memories for a lifetime. So one day my kids can look back, and say “That was my dad”. I wish my father had filmed his crazy adventures. And his over 100 cars and over 70 motorcycles he owned. I’d love to see it.
I know that was long winded. But that’s a short summary. 💪🏼
@Link’s Garage Your words resonate with me 100%. Part 1 , precisely, help other people with videos that show the whole process, no crap ,no making it look easy when it's not , no important stuff missing, just facts with views you can actually see .
Part 2 .This is where the heart of it resides. Those private videos capturing memories for your kids .You figured out a brilliant way to capture and store moments and memories on youtubes dime .A free library your kids ,grandkids and future generations can access .No more lost photos in shoeboxes that fade over time .We think alike .I've done the same thing .
Your dad sounds like an amazing guy. Hopefully you have at least a few faded photos in some old shoe boxes of some of his bikes and cars and adventures.
One thing is for sure ..you're a good man.
@@TRyanLearnBikes hell yea brother. Maybe one day we collaborate. Could be legendary. Cheers brother. 🍻
@Link’s Garage Sounds good, cheers my friend 🍻
Awesome detail! Subscribed!
Hi Mat .Thanks very much for your great comment and also subscribing. I genuinely appreciate it. Cheers 🍻
This one FINE instructional video. Truly outstanding.
Thank you very much, Microsoft teams .I appreciate you taking the time to watch and leave such a positive comment. Cheers 🍻
Hope this guy has more videos like this. Get er done, and roll.
Thanks for the great comment .Cheers to you good sir.
What year model is the bike in the video? My 2001 yz250 didnt have a "external linkage spacer", also the drawing in the manual didn't show one.@@TRyanLearnBikes
@leelafarlett3535 Hi Lee ..the bike in the video is a 2005 .Yes your bike may very well not have that particular spacer .I have noticed slight variances between certain year machines. Thats why it's always a good idea to consult the manual like you did .
Got mine together, and the main valve opens easily. After its' all the way open, the other two begin to open, and I feel tension from the spring as they open. Is that the way its supposed to work? @@TRyanLearnBikes
Hey Lee it sounds like you've got it set up right .There is bit of a lag in timing between the main valve and the two side valves and a noticeable increase in tension when fully open .As long as everyting moves freely without any notchey stiffness you should be good to go . If you get a chance keep me posted when you get it all put back together and running I'd be curious to hear how great your bike is running after you go for the first ride .Good luck ahead I'm sure it will run beautifully . @@leelafarlett3535
I'm glad I found this video, going to do my first top end on my 2015 YZ250! I've subbed for more!
Hey Thats great 👍 Thanks very much. I truly appreciate it. Good luck with the top end work ahead. I'm sure you'll do fine .Cheers to you good sir 🍻
Excellent video! Keep up the great work!!!

Great video best I've seen
Hey Eric, thanks very much. I really appreciate the kind words. Cheers 🍻
Keep up the good work Godbless
this resonated with me... i love pancakes. next level instructions/editing, thanks for the effort!!!
Hey Robert, Thanks very much for watching and taking the time to leave me such a great comment .Also for reminding how much I enjoy pancakes and maple syrup. I'm going to go have a stack of them right now .Cheers man🍺
@@TRyanLearnBikes funny shit!...I'm balls deep in a 2005 yz 250 off road build, this yz is my second, the first was a track specific ride, this one has an Eric Gorr BB, smart carb, WR trans, HInson, 18" rear, SSS fork. I did a refresh some 15 hours ago but had a failure when the PV linkage spring broke and somehow the fragment made it's way into the cylinder. Have you ever heard of this ? Any way we are 8 hours away from fueling up and kicking!!! Overall I'm super happy with decision to focus on trail riding, for 50 yrs I've only really road tracks, this has been enlighting! Thanks again for the superb edit/instruction, well done brother! enjoy the CAKES!
@Robert White Hey Robert ,Holy moly man you are into some serious bike building. No I have never heard of the same issue you experienced with bits fragmenting into your engine ....thats sounds like some wild stuff going on there ,yikes.
You mention many years of track riding and now focusing more on trails ..You are obviously a well schooled rider with heaps of experience. You would have a massive audience interested in what you're riding and building if you ever decided to record it and put it on youtube. I would definitely follow your channel. I really appreciate you watching my video and commenting so positively. Cheers my friend and enjoy many more years of riding and maybe record some of your bike adventures if you get a chance.🍻
@@TRyanLearnBikes I appreciate that encouragement. I see the committment that guys like you have and for myself right now I'm lucky to have an afternoon to go ride the thing... I do have cameras and mounts... but sadly have never used them, for fear of the ensuing rabbit hole 😂Keep the edits coming, everyone has their niche but you've figured out some key componets to a successful/entertaining tutorial.
@Robert White I certainly understand Robert ,time is the elusive element and riding is way more fun than messing around filming and editing. The CZcams game can definitely be a demanding rabbit hole to navigate. Thanks again for watching and commenting so kindly. Cheers 🍻
super awesome editing and information. this channel deserves to have much more views and subscribers. I liked subed and going to watch all videos! thank you for making them! very quality stuff. very inspiring. too
Hey Damir I can't thank you enough for your kind remarks . You made my day . I truly appreciate the fact that you took the time to watch ,comment and subscribe .Cheers to you my friend !

Such great detail, great how to video ............................................................JB..
Cheers J.B. 🍻
It's all in the details. Well done 😎😎 Another thing to add to the next one might be showing the step where you verify it works properly....I know you did that 😜
Ahh, yes, Tim ,good point .I will definitely add that concept to my next endeavor. Thanks for watching and taking the time to comment. Cheers 🍻
From an old timer with engineering degrees and engine building/modifying experience, starting to ride again, you do a very good vid. I have a question you may know the answer to.
With a stock motor now, I am planning on doing some easy mods to the engine for quite a bit more low end power for my trail riding. Among those mods I want to lower the cylinder .5mm, (no cylinder base gasket, used a good gasket sealer. I think the stock gasket is .5mm), so I am wondering if there is any linkage "actuating rod", (somewhere between the governor and the valve shaft), adjustment needed, or built in the linkage to do so. I think I would like the valves to open at the same rpm, and I can't remember if I even bothered with earlier bikes, (I have lowered the cylinder on earlier bikes that had power valves,---a long time ago.). Thank you. Doug in Michigan
Hey Doug that is a really good question .I don't see an option to adjust anywhere in the linkage .But this question must have come up with someone else doing a similar modification .I will be heading to a fantastic bike shop this week .I'm good friends with the mechanics on site and will pose that question to them .If anyone knows the right answer ,its these guys ,they have decades of old school experience .If they can give us any solid intel on this question I will certainly let you know what they say .Thanks very much for watching and taking the time to comment with intelligent interesting thoughts .Cheers to you good sir .
hello! in my cylinder there is no external linkage spacer, do you really need that spacer and what is the measure on that? good video!!
Well it may be a good idea to confirm that your particular year of bike actually had that spacer .A quick look at a parts diagram would help you with that .Your local Yamaha dealer should be able to provide you with it ..As far as the actual dimensions I'm not sure as it's in my bike right now .Let me know if you have trouble finding out the info required and I'll check with my shop here in Ontario to see if we can get it sorted for you .
I have a 2023 yz 250X and it drips oil out of the power valve vent line is that normal.?
Hey Mathew, it's not uncommon to have a little bit of black oily goo drip out of the vent line .Depending on your fuel mixture and how well.your bike is running can be factors on the consistency and amount of oily discharge. Over time it gets pretty messy and sticky inside the power valve compartment and is well worth cleaning it up every once in a while to get maximum performance out of your engine.
Min 1:04 I am surprised the inner coil spring coils wore into the shaft like that. How much time is on that bike? Also, what caused the wear on that same shaft, but to the left end, between the "pulley slot" and the retaining shoulder of the shaft? Was that wear done by the seal?
You have a great eye for detail .I wondered about those wear marks too.The bike was previously owned by an avid racer who I'm sure rode it hard for a few years .It had an overbore when I got it and Ive since replaced that with a new jug .The power valve components are likely all original parts .I really dont know why there was heavy wear near the pully slot as you mentioned .
Thanks for watching and your great comment .
Cheers to you good sir .
Excelent👍💪🤩
Thank you Jakub .Glad you liked the video. Cheers 🍻
Subscribing to TRyan's Channel if you own a dirt bike is the equivalent of a thousand dollar discount coupon. After labor and parts and tools and time bringing it to a mechanic, there's no question he is saving us major dollars that we would have spent on a mechanic , or possibly making expensive mistakes doing it ourselves without a pro. I think he should actually charge a small amount for the info. He saved me thousands, so I'm sure there are appreciative people like myself that wouldn't mind tossing him a few dollars.
He is saving us hundreds, what's 5 bucks. 1.45k subscribers x 5 bucks could add up ya know! :)
Hey ascended Lion I truly appreciate you promoting my channel in such a kind way . It really feels fantastic to be recognized in such a positive light .The thought of receiving donations or any kind of compensation for helping out the motorcycle community is interesting, but not necessary at all its genuinely my pleasure just to help people out .Thank you so much for your support and making my day .Cheers good sir 🍺
i think something is wrong with my cylinder. I looked extra close but i'm definitely missing something. at 4:30 there are a couple young children inside your exhaust port and mine doesn't seem to have those. are those stock or where did you get them?
Well Benny ....that little easter egg is not a stock option .I'm impressed you actually spotted it .Not many have . It was a nod to two of my grandkids .The thought prossess was ,if by chance they ever were to watch any of grampas videos 30 years from now ,and they found their cameo ,they would know I was always thinking of them . Thanks for watching and taking the time to comment I truly appreciate it .Cheers

Familiar as suzuki rm 250 06 one 😊
Ahh yes ...That is a beauty of a machine.
@@TRyanLearnBikes ive got as you see the picture, Kawasaki kx 250f 04(same as suzuki) flat track with rm 250 06 engine, 80% of swap has done (hardpart) chain line is perfect needs 2.8mm washer on left side and 5mm right. Fuel tank bottom needs to pushed in 2cm to get spark plug clearance, cyl head bracket on (frame) 90° turned back so you can remove engine without undo head. There is video about it if you want see😅 ive be the first one to do this
@KawasakiMotoX2T Wow ...now thats pretty cool .I will definitely check that out .No matter how you slice it that is a ton of work.
Cual es la medida del reten del eje
I'm unsure of the actual dimensions. That would be best determined through a Yamaha parts dealer .
Maaaster!!!!!

@@TRyanLearnBikes I repair an old Yamaha DT200r and have big problem with YPVS servomotor and I was very curious how it works on the YZ's without all these extra parts.(battery,servomotor,cables).

Is there only one oil seal on the side where you slid the shaft or is there one on either side?
Thanks
There is only one oil seal where that shaft slides in on this particular model .Hopefully, this helps.
@@TRyanLearnBikes
Yes this helps I appreciate it. My bike is a YZ250 01 model and I think the tusk gasket set comes with two of those seals, it's why I asked about that but thanks for the reply, feedback like this is always useful.
