Seller Said This $950 Dirt Bike Won't Run (Crankshaft Breaks In Half)

[@minnesotatomcat]

It’s the best feeling in the world after they fire up after something like that! Those couple minutes before when you’re getting your leg all stretched out to start kicking and you’re thinking about all the time and money and work you just put into it just makes my stomach ball right up!!

[@ianmangham4570]

Awesome seeing her ALIVE at the end ,all fresh and ready for a happy customer 👍

[@BradyinAlaska]

Hi from up in Alaska. I just started to watch your videos. And not many people can do what you can do. You make it easy to follow. And I'm 16 years old. And I am learning to work on small engines. And want to say thank you for the easy to follow along videos.

[@cybermiester]

I like your attitude. great way to be if you wanna be successful!

[@BradyinAlaska]

@@cybermiester thank you. We need more people like you!!

[@ShawnPittman-r2l]

I’m a motocross Dad/ Vet/half ass mechanic…. Live your videos. Couple things, run or start your bikes outside or at least get some ventilation in the garage ( hate to see you or your pup getting sick). Power wash the hell out of the bikes before breaking them down. Good stuff keep up the good work

[@DeathDealer1825]

He has 2 garage doors and his garage is massive probably also heated and air conditioned the dog is fine

[@danburby7936]

JOE,YOU SHOULD ALWAYS PUT GREASE ON THE SPRING SIDE TO KEEP THE SPRING FROM POPPING OUT

[@stevenlandis6847]

Bro u are a beast. All these people dont understand that with your skills, you can buy a non running bike put a couple hundred dollars into a 950 project you got a brand new bike. Good work keep the vids coming.

[@transmitterguy478]

Joe, it's great you tear them down and show how to put them together right. I'm sure you are teaching a lot of young motorheads how to do it right, great job.

[@kevinschultz2129]

There's nothing quite like the sound of a well tuned and fresh 2-Stroke! I bet that thing rips. Nice job on the rebuild Joe!

[@AnthonyRBlacker]

I had a feeling that bike was going to be a sweet runner.. that thing sounds SO so good Joe.. great work man.. glad you went the extra mile on it, totally worth it!! Takes me back to the 90s man, feels SO good with those memories!

[@minnesotatomcat]

I’ve used that trick many times cutting a nice deep slit with a dremel to get a screw out. If you suspect loctite a little bit of heat does wonders in loosening it up 👍

[@paulweigle6872]

That machine sounds great!!! Fantastic job young man.

[@KivistoJJ]

Good video once again, one thing that have to be corrected is that the CRANK SEALS are not meant to be oiled, especially from outer edge, they can pop out from the crank case pressure!

[@MR-puffnstuff]

Horrible breaking in conditions but great breaking the machine again conditions. But you absolutely hit a homerun on the rebuilding and sounds so nice to.

[@rowdy0190]

8:04 When you lived in your old house you used to put the seal with the spring facing in not out, that's what you did with the CR80 and you said that's the correct way.

[@neilmcintosh1200]

Yes, the pressure is inside with the crank, not in the clutch case. I think Joe got this wrong this time. But it won't fail for some time.

[@16507487]

I am busy working on an 07 RM 250 and I just want to say that your videos are simply inspiring. I have such motivation to get my bike perfect and the knowledge that I am getting from watching your videos is invaluable. Thank you for your contribution Bru, best regards from South Africa!

[@svoctopus4888]

Next item on your, to buy list, is a farm with a huge barn and 100+ acres of land right out your barndoor to rip and ride all of your machines. Oh! A pond too!

[@2vintage]

The dream!

[@TroyRosenbaugh]

We got an 89 XR 250 R in a few weeks ago, rods gone clank city. Ordered new crank, bearings, etc. My assistant hollered at me yesterday, Boss, you need to see this . Crap, what now. The new crank is cracked on the left side right at the counter balance, Wiseco. Everything else is good.Brian really checks that new stuff out good, and I'm glad, he finds issues quite a bit. They're sending out a new today. Great vid Joe.

[@chrisbilling]

Great work. Thats the clearest sounding 2 stroke i think I’ve ever heard

[@yeti8it396]

Back in the day I used to race before I got sponsored I used Wiesco pistons often and always had good luck with the brand. Same with my friends.

[@ryanparr8669]

That's a great bike, Joe, and you got a killer deal! I love when you refurbish bikes that I have, brings back memories.

[@scraech]

I think you could benefit from a bench grinder with a wire wheel on one side. Please keep the videos coming. Pleasure to watch you.

[@WriterGaming]

Great video, but you should not use the impact to tighten bolts on the engine unless you torqued it down

[@robertalexander2506]

You make it look so easy splitting cases and going through a lower end! I have never went past doing an upper end, never had to, but I'm not that confident messing with all of the gears and shift drum! You seem to do it in your videos without having to look at a Service Manual too. That Bike turned out great, sounded awesome!

[@edjacobson8480]

Love your videos - you take the toughest projects. The best way.

[@TenRing69]

I just found your channel around 1 week ago, subscribed. You are one helluva mechanic. Great job fixing that YZ!

[@marcalan1198]

Your throttle blipping insesantly drove me nuts when it's a fresh rebuild. But i must say fine job young brother . I've been to countless motocross races and your yz 125 sounds and runs like the brand new Yamahas I've been around. Two thumbs up 👍👍

[@800_k_7]

It sure seems that buying a motorcycle from Joe is always a good investment, Joe you are the best motorcycle mechanic.. nice collection.. Awesome to travel on two wheel. Keep safe.

[@mauriceclark4870]

You. Sure. Are. An. Engine. Doctor. !! Watching. You work. Is. Facsinating. ,!!!!

[@stevefritch3180]

Excellent work Joseph! That YZ does sound awesome. The video was (in my opinion) very well done. You explained things well as you went through them. Keep up the great work and I look forward to more of your videos. 👍

[@thebigguy8306]

Wow, a brief glimpse of the fleet in the intro. Great looking cycle, sounds great. Always a learning moment.

[@TroyRosenbaugh]

Hardened steel will break when dropped or hit with a hammer hard. Sucks, way it goes.great vid J. Great job.

[@mattmccleary1278]

You should have cleaned the scale off top of head and engine. Makes it look nicer

[@bryanbard1840]

I miss the years of working on the race bikes in preparation for the hillclimbs. Awesome bike, good job!

[@RicardoValdes-r6w]

Another excellent work done and absolutely sharp new rebuilt to your 98 Yamaha ..

[@troolllllinnnzaragoza3169]

“What a beauty” I admire your appreciation for bikes, kids nowadays just don’t have the will in them to make something like new again. May not be a 10k bike but it’s still something to be thankful for!

[@jordanleonard8198]

Yes they don’t but we aren’t buying a 2013 KTM 250SX for $3,900 nor am I paying $4500 for a 2014 Suzuki RM-Z250 with some mods when I can find another closer by with the essential mods for $3100 and the person states they’re negotiable with the price. People need to quit thinking their decade old bike that’s been rebuilt is worth more than $4k unless it’s been meticulously cared for. It’s been damn near impossible to find a bike that isn’t completely clapped or completely overpriced. Even my guys I play MX bikes with that actually ride freaked tf out when I showed them the very few local bikes for sale and even a friend I went to school with who had many bikes said there’s way better deals out there. I wish I knew how to work on a bike but I can’t even get one to try. I have a budget of 4k and I’m about to look at a 2014 Suzuki that’s been rebuilt, the owner got it a year ago and barely rides it. He purchased it from a dealer it doesn’t have a title which I don’t care but I know nothing about it’s owner(s) and what’s been done to the engine. So it’s a risk at the end of the day.

[@markhensley9378]

I'm glad you decided to spend the money and make a video. Satisfaction feels good.

[@ladyjedi3D]

That bike with the steel frame is sweet. Sounds amazing! Would love to have that bike. They are selling for a premium here in cali and theft is horrible. I keep everything in my house. Say hi to Vinny!!!

[@fraes2465]

Great vid! Still the undisputed master of shifting from first to neutral 😅🥰

[@rodneygreen9968]

I just subscribed to your channel. I see that you have a lot of knowledge & determination to get engines running again. That is Fantastic. Keep putting out new videos.👌👍👍

[@RicardoValdes-r6w]

[@richardmathews783]

Please title your videos parts1, 2, 3 etc so that they can be watched in order - hopefully to completion. You have the patience of a Saint!

Lets go i was waiting for this video,and i love what you do keep up the good work 👍

[@leewaken5059]

The cleanliness and attendtion to detail you give to your projects are quite.........................well, not very pretty. It runs, you're happy, congratulations.🏁

[@buzzy1011]

Looks like you had to take care of a lot of things on this bike….. but it sounds like its dialed in perfectly.. Sounds really good…. And looks really good too.. Seems like a keeper…

[@mikehudge78x]

Excellent example of reassembly of this Yamaha engine- just what I do on crank bearing install is I put each case hole for bearing on a light bulb overnight imo this warms. Evenly and gradually to avoid cracking case - I learned this from a senior mechanic when I worked in a Suzuki Kawasaki shop years ago 😅 I currently work for Toyota almost 25 years now - great 👍 video Joe - how's the weather where you are?.I am in northern Minnesota and our ice races canceled yesterday as we could have rode jet skis lol 😅

[@donaldblakley6796]

Excellent work bud, sounds great.. I wondered what happened to the broken crank yz.. again from your previous videos.. good thing you greased the gasket instead of gasket maker, so you can take it back off easy just incase... which worked out in favor this time to replace kick start assembly. Smart:) nice that sexy clutch basket cover could be used again. Lol

[@chokeonnick]

I wish I had the tools to do this stuff. Looks like fun. Great videos dude. I have a 2004 Honda crf 450r. And the valves always need to be shimmed. After about 12 hrs or ride time. I really need to Gain the confidence to do it myself. So I quit spending so much money lol.

[@mauriciogalvis4708]

BEST Video!!! step by step instructions!!! Thanks Buddy.

[@faroutgenetics59]

Having the suspension set makes a huge difference, we had a 1999 YZ125 and riding over really rough trails you couldn't feel anything it was the best riding 125 I ever owned sadly it got stolen from my driveway but we had cameras and we found the guys who stole it one of the guys mother paid for the bike, because they tore it up

[@zakkopanske2147]

Hard work, great finish. Respekt.

[@11GalleryATV]

Nice looking and sounding little bike ... I dig the blue and white ...

Nice work! It sounds really good. Yeah I’ve tried riding racing bikes in snow and ice, it very dicey. Lol have a good one.

[@benburton8463]

Well u got that bag of old nails up n running and no horrendous bodges for next owner to find. Ive been through all this many times. Some times you think how did i miss this when buying it but ur not alone on this one

Sometimes putting the money and time into an engine rebuild is is just the most satisfying thing ever! Man I can watch your videos 24/7 I absolutely love it!! Thanks for posting

[@mattirvin3121]

[@jasonwoolard1886]

My favorite bike.. light and nimble.. great work!! That’s a keeper…super kleeaaaann!

[@DblK-BMorphs]

Been waiting on this one to come back!

[@diggy-d8w]

Well, these videos offer proof when ya sell the bike of just how far you went to do things Right ! Good selling point, I say .

[@diggy-d8w]

So does the shaft get broke when trying to kick-start the bike or is it related to some of their other jake-leg repair things? I mean when the case was cracked might that have caused things to get tight somehow? I only ask so I don't do something stupid myself.... lol, thanks for all the videos.

[@simby787]

nice effort there, it seems very lean on the pilot circuit

[@charlesshort4287]

What is name of the sealant for the case halves, i enjoy watching how you do the work on so many engines, i am about to take the challenge of replacing the crank on a cr80, great channel you have going on, been with you over 5+years now , I have watched you grow and become a great bike mechanic that will take on what ever engine job that is in front of you, my hat is off for you,

[@craigmorgan4676]

Joe,love this build,that thing sounds new brother, so crisp,beautiful!👌👏🏼👍💯

[@TroyRosenbaugh]

Need a set of open face crows feet sockets/attachments for that torque wrench to do lower jug nuts, etc. Very handy not expensive.

[@EdOBara-b5j]

Watch your thumb around that torch! Love your videos, watch them all even though I'm between bikes..thanks. Where's the wife, sweet lady, miss her;).

[@matthewstuckey665]

Sounds super crispy. Great work man.

[@Asdfsaur]

Lots of tips in the video, I love it! Thank you for the content, I enjoy it very much 😊

[@EarthSurferUSA]

Breaks in rotating shafts like that are usually due to the shaft not running true enough, (run out). The slight imbalance (in alignment, not weight) actually causes the shaft to bend ever so slightly every rotation, at the edge of a bearing. The result after enough cycles, is a pretty clean break like that. You will learn about things like and and so much more in your mechanical engineering studies. Fluid dynamics is great stuff to know too IMO. I never did study that. Or, you can see how much time it takes you to figure stuff out yourself. :) Doug in Michigan

[@yhird]

Beautiful bike! It sounds fantastic. Magnificent work. Thank you for sharing. Cheers.

[@inthesPhila]

I enjoy your videos and thanks. About all I do is check and set valves and replace clutch packs and change oil and filters on my '03 EXC 250 4. Have done serious work in my '85 K100RS (bull gear and sprag clutch) and Stator in my first year R1200GS LC. Did reground crank, rods and rings in a '65 bug in the 80s too.Thanks again.

[@Military-Museum-LP]

Good job Joe.

[@GNX157]

Joe, if you have to resort to slotting a bolt head, at least use a hollow-ground screw driver to give yourself the best chance at removal. A HC screwdriver will be much less likely to climb out of the slot.

[@robertpowers9174]

😊 It's your baby. Nice work.

[@williamwonders9265]

Love your content. Keep up the good work. You ever think about restorations to work on in addition to what you already do?

[@michaelgarland579]

I just replaced my piston too yz125 2003 with same one in this video wiseco makes good pistons this is a good video to learn from

[@ausmartin1]

Great 👍 idea 💡 to grease the oil seals including spring so they don't pop apart if you need to tap them in.

[@Bartman4800]

I never see you degreasing the taper male and female before you install the flywheel. If they are oiled, they do not grip and are one of the main causes of a woodruff key failing... But otherwise GREAT JOB and love watching your channel.

[@MrSparks701]

Enjoyed following the rebuild. Thanks for sharing.

[@jayaustin3096]

Great looking bike Joe. Long live the 2 strokes.

[@greathornedowl3644]

Bravo, great bike with a little tinkering. Fun little ride in the winter, dirt bike or snow bike? Keep up the hard work Was that Jade's toothbrush you were cleaning with? Vinny is angry, hoping repairs didn't come out of Gravy Train budget

[@kenandavidson8460]

No idea if you still have this bike. I just rebuilt a 02 yz125 with a similar catastrophic failure. I do think the right side crank seal is not supposed to be ring side out. Ive checked other videos and consulted a guy 25 years experience working on dirtbikes and Im pretty sure you have it in wrong. That of course means it was in wrong to begin with because when you opened up the engine you can see the seal was not in the right way before you installed the new one. If it is running great now then might as well not mess with it but eventually I think it'll be a problem. LOVE YOUR VIDEOS THOUGH. Just wanted to let you know.

[@ragnarironspear1791]

I've only ever seen a crank like that in a 1050 Triumph, it ended up putting a rod out through the casing 😢

[@DiyClassics]

Dont grease oil seals before installing. They could pop out. Only lube up with 2stroke oil after

[@fred-san]

rear tire studs a small hand saw (buscraft type, with curved blade) and a slot in the middle of the central stud tires will probably wear out faster but will give a little more bite (tip poor trialist...)

[@GNX157]

Joe, if you’re going to reuse copper sealing washers, to be effective, they need to be sanded/polished smooth, and re-annealed by heating with a torch until glowing red and allowed to cool. Aluminum sealing washers cannot be re-annealed.

[@EarthSurferUSA]

Calm down. I know what you say does have merit, but is it needed for a screw washer or it will fail? If the surfaces are not damaged, (2 pretty soft materials) and you clean them, they are usually fine and don't leak. If they do, just get new washers. I have never had to do that.

[@GNX157]

@@EarthSurferUSA It’s always good to replace copper sealing washers, but re-annealing returns the molecular structure to what it was before being crushed, and restores its sealing ability. Why you have to say calm down, I don’t understand. It was just helpful advice for him and others in a predicament without having new washers.

[@michaelmitchell5909]

Awesome bike, sounds great Joe. Another super good job man....thumbs up from me man... I'm curious why you don't use gasket cinch on the cases?. Tatro machine uses that on the gasket and on the case halves, he says it won't contaminate the engine if some if it gets inside....it just disintegrates..

[@somerandomguy3868]

Very nice job, sounds right and tight

I believe that the yellow bottle of torch gas is called Map gas, and should heat things up quicker for you.
