He tore it down, found out the crank was done, then put the cyl back on so u couldnt check the crank lol. Idk about up there but here u gotta assume every seller is lying about everything lol

As soon as he said he works on big rigs for a living, I knew you’d be in for an adventure. 😂.

Good job Joe on finding another fixer, saving a machine from dying and keeping the Sport Quad's going. I posted in Joe's KX $500 bike find how he's getting these deals. This isn't aimed at everyone but those that freak out about this comment are the ones you can get the deal from. JOE!!!!! Don't sell the CR500, get rid of the SXS. Do a poll see what the viewers would do. Now for Straight one line answers: 1) Yes the seller smoked the engine and tried an STP oil additive, when Joe drained it you can see the separation from the thicker sludge. 2) When pulling the swing arm bolt out, remove the rear shock as it's putting immense pressure on the bolt. 3) Replace all swing arm and shock roller/thrust bearings, they may look like rusted washers and when they lock up permanent things wear. 4) Inner bearings/seals no matter how good they look, there is more wear than you can just see. 5) Flush cases/gear assembly in a solvent bath, part cleaner, mineral spirits to remove any slivers of metal 6) After a total rebuild ANY metal on metal contact gets "Assembly Lube", I use the red Summit brand, local stuff can be bought at any automotive store. Misc info: -The cylinder has a steel cylinder liner so sticking a magnet to it only proves it's steel not a nikasil coating. -If you get a new to you machine change and flush all fluids filters, replace spark plug. NEVER take the sellers word. -To #3) A test to prove the bearings are junk; jack up bike to raise rear tire off the ground, pull up on the wheel if the swing arm moves up 1/2" or more bearings are scrap and make the rear bike loose and dangerous. -BIG ONE HERE!!!!! The RPMs are adjusted on the CARB IDLE SCREW!!!! Not the adjusters on the handle cable. That's a Rookie -Make sure the brakes work freely and don't stick or work at all. Bleed the system if you have hydraulic brakes, it only takes about 8-12oz of DOT Brake fluid to do the whole system. Black or brown fluid is bad and very corrosive. Pops

Another great tear down & assessment on what the problem was. You’ve done a lot of top ends, but I’ve enjoyed seeing you go thru the bottom. Very informative. I’ve never tackled a bottom end before so it’s really nice to watch the tear down. Nice job man! Can’t wait for the rebuild & 1st ride

I believe that’s why people do the oil mod on the 04-06 yfz 450

I think he knew what had happened so drained the oil so it didn't show when the next person checked the oil for metal flakes. But I'm sure you will get it sorted and have fun fixing it and then out for a rip. Great video as always.

That oil you drained looked pretty dang clean... I'm assuming he flushed it a couple times to get the metal flakes out.

"So at the top of the stroke, it gets stiff." Sounds like a fun Saturday night!

Good buy for $1000 joe. Just make sure you do the oil squirter mod and change the oil pump aswell. I’ve done two carb yfz450 engines now and I actually enjoy rebuilding them too. You do need a bigger hammer though 🤣

Idk why people cut the front fenders off it’s just stupid…

Reason the cranks fail on those earlier YFZ 450’s is because they have a bad oil pump from the factory. To fix this issue use a 2007+ YFZ oil pump

The 2004-2006 YFZ450's are notorious for crank bearings going out ... especially if you don't keep up with the oil changes ... In 2007, Yamaha added the oil squirter to the clutch side case cover, that shoots a stream of oil into the crank rod bearings.

Regret? Oh it's just a clickbait title

We pull started it with a forklift. Lmao

That cylinder would of came off ,and you can hear the lies in his voice when he said it ran good when it fired back off

This dude can fix anything thing . I definitely appreciate this mans skills an it gives you ideas to help you troubleshoot your self

"He said he does not know what was wrong with it, so it could be something simple." One heck of a compliment there huh. haha

2 vintage you are my savior I’ve been trying to find a good video on that swing arm bolt because the one on my 660 is super stuck… THANK YOYU

Might have helped getting that swing arm bolt out if you supported the swing arm itself and the engine lol

I was watching your videos from the beginning and I like that you showed the quad in the ad like you did back then. Really dig it.

That damn seized bolt goes through the swingarm too... you need to unload the rear suspension.

Service those swingarm bearings with grease while you have it apart!

Lube it up and air hammer it back in. That's what I do on tough bolts

41:04, he reason the BOLT was so danged hard to remove - after it was almost out, was that you had "ball-peened" the threaded end so much, the diameter of the threaded end was so much MORE than that of the hole, which resulted in the force needed to slide it through Can I make a suggestion, for the next time/s you have frozen bolts to remove - use a car steering rod bearing puller, but have a sliding hammer that you can screw into the bolt hole of the claw, instead of the bolt which pushes the steering joint out of the arm. That way, you will have an "in-line" hammer - instead of that 45 degree obtuse angle to work with.

You can disconnect the rear shock from the frame and then lift the swingarm up to relieve tension off that swimgarm bolt and it'll come out easier

I really like the addition of the in person purchase, it's gives us a better understanding of the video.

Worth $1000 even if he had said the crank was bad. Good deal and a good video so far.

Hope you find some dual sport to supermotos in the future

Good job Joe, yeah swing arm bolts are a pain in the ass. I had to cut mine out on the 2005 banshee I picked up. When I put in the new solid bolt in I anti-seize the "fudge" out of it. Already can't wait to see the next video on this quad.

Sitting for 2 years and it has a 2022 sticker glowing at you

As nice as this looks the guy probably couldve parted it out actually and made more money lol. Happy this quad is in your hands tho considering I know you'll get it up and running again soon!! Love your content man, you do a great job with all these projects!!!

Good video as usual. I'd recommend tapping the head end of the swingarm bolt and using a slide hammer to finish pulling it instead of the air hammer and a chisel. Also, a longer soak in Kroil might help. I've used it to lube bolts on equipment in dams that had been installed in a damp environment since the 1930s.

Nice that the seller allowed filming, makes a pleasant change. NEVER leave possessions out in the open unattended!Maybe should've used a long drift bar, with the Hammer action drill thing (interesting solution l'll remember that) and kept going from the Right Hand side? Amazing the top end and other parts survived, good job it stopped turning over!

You got some really good videos like how detailed they are and you do good work. I liked seeing you doing the deal and picking up the new project. Keep the good content coming. I can't wait for the next one

Buying a non running half tore down machine is a crap shoot. Have to assume the absolute worst irregardless what the seller says. But…. Joe can handle it. I’ve seen him work with way worse!

Love your videos man keep it up love the hands on and being real about your bikes

A quality slide hammer set with attachments would come in handy for removing stuck swing arm bolts and many other things.

You can't regret buying this because you already knew what was wrong lol

Legend says that this kid went on to become one of the top sales man of the 21st century .

Y have I never knew u had a second channel that crazy u should definitely mention it next video

Swap a yz250 2t motor if you don't end up rebuildin!

One of your best videos here, very impressive. Been watching for years and will watch for years to come.

Top work! Love how methodical you are when you get into an engine. Makes me wish I had a project bike to tinker with.

Good buy joe for a $1000 you will have that up and running in no time mate and make a quick return on it easy unfortunately it is what it is at the moment but these things fetch good dough take care mate look forward to the rebuild and test 🔧🔧🔧👍👌

That's good they replaced screws with 8mm head bolts.. only way to fly.

For someone that works on semi trucks it doesn’t seem like he knows much about it and seems like he’s fibbing about what he’s knows about the machine

You can use a flex hone on nikaseal, look it up. Would be worth your while considering how glazed that cylinder is.

Great deal in my eyes since you do all your work saved hella money and good video man I love the long ones and the motors are fun to tear down when it’s not your daily and no rush to get it done

You need to remove the bottom shock mounting bolt to remove tension from the swinging arm,so the bolt will come out,ive had this problem.

Where do you find your deals? I’ve tried to find new projects but never can find one. I can’t sell mine either.

I'm new to your channel but catching up with your content. I'm in the UK 🇬🇧 and must say you really get some bargains . Over here bikes and stuff are so hard to find cheap. Love the channel keep up the good 👷

I have to say I throughly enjoy your content, your a very likeable honest character. I have had the very model of quad myself, totally rebuilt it in 2015. Would love to see you find a banshee to restore. Keep up the good work from another Agri KZfaqr in Ireland 🇮🇪

Its an 04 i will Recommend to do the 07+ oil mod on the clutch case for the rod and replace the oil pump for an 07 one. Since that most likely was why it broked.

This guy knew exactly what he was talking about Joe he got you good man

Put nut on end to save threads, use a 3lb sledge.

LoL, the guy lied straight to your face, and the camera, about saying he checked the bearings. I'll never understand why people lie when they sell something 😂

Glad we got to see a full tear down again. Ho Lee Chit you certainly know engines. It will be interesting to see what more there is to be fixed .

You need to invest in a crankshaft press jig if your going to be doing this for a while so it will save you a ton of money! On that swingarm bolt try drilling a small hole in the center of each side and putting pb blaster for a day or two

makes sense why it did not have enough power to turn over enough ! way to go on the bike for the deal im sure youll get it going in due time.

04-06 need oil mod done. Deff see if it has that and if it doesn’t I bet that’s why this is causing it.

The way you went from “Not a single little bit did that budge” to “Alright we’ve got the air hammer!”😂😂😂😂

Damn, the seller's voice sounds like your clone, Joe! lol

That was my next guess on it to the rod bearing got fired due to lack of lubricant inside of it from being overheated over cooked oil.& Low on motor oil to will cause those issues on those fourwheeler engines for sure.

This is really impressive ! Thanks a lot for sharing, so nice to discover how this all works inside, and how knowledgeable and handy you are on this ! Wow, awesome !

check intake boot and airfilter. biggest mistakes. lack of maintenance

Would have helped with a jack underswingarm to reduce weight on the pivot bolt for future reference 👍🏼

for the love of god please get yourself a four pound sledge and a slide hammer kit. we aren’t framing a house here

You should do the oil mod to that thing I think 04 -06 have a lower pressure pump and they do not have a oil squirter that sprays on the rod I’ve done a few of them with basic tools I’ve had one of the 450s I’ve done for seven years and have had no bottom end problems

1) Spark at the right time. 2) Enough compression to run. 3) The and the fuel/air mixed up at a good ratio. Those are the 3 main things you need for it to run. Checking spark and compression is pretty easy. Still have a problem---fuel delivery is all that is left.

I would check the shift forks closer, if there is any rotational marks on them they're bent. Better safe than sorry.

04-06 were notorious for rod bearing and wrist pin failure do to lack of oil reaching them in 07 they added an oil squirter to fix the issue and for 04-06 models you can replace the right side cover witha cover from an 07 and replace the stock oil pump with a high flow oil pump to fix the issue.

Doing a top end on a 2016 Yamaha yz250f now. It got swamped. Actually compressed the top ring into the piston.

I used a claw hammer for a long time on everything myself so I get it but for real a mini sledge has saved the day for me countless times

i would have tried putting a jack under it and lifting it a little bit to take pressure off of it.

Great video love the fetching and the fixing same video. I might be doing this on my Ltz 400 I picked up figuring it about same process

Take your channel to the next level by vapor blasting and reconditioning these older dirt bikes. a little spit and shine wouldn't hurt.

9:49 soon as he said he forgot how to pop the seat off that he has no idea wats wrong with it

Parts list... piston and rings, full engine gasket kit, timing chain, oil filter, might as well get the hot rods engine rebuild with a crank. Heck get the wiseco for what like 1100? Itll sell for 4k or more joe

Those swing arm bolts can be a bear. Tip is to jack the quad up a bit to take some pressure off the swing arm.

They do have A newer weld out now to it's called gorilla weld from gorilla glue company. Like JB-WELD it's just 5xs stronger is what is stated on the packages.

I saw it up for sale! Bottom end needs rebuild

Throw away the damn claw hammer joe. You need a few ball pean hammer’s and a small sledgehammer

Honestly looks like it got hot and seized blued so… definitely got too hot… I also suggest you pull the metal filter on the bottom of the oil tank and replace it filled with metal on my 400 and also had to torch out my swing arm bolt fyi

I had my nickel plated kx 85 cylinder bored and Not replatted been running it for 4 years now like that with no issue.

If you don't replace the bearings and totally disassemble it to clean it properly, then you are absolutely the WORLD'S BIGGEST HACK!

Watch JR Go his dad said and proved that if the bolt is seized in there or rusted in there just lots of penetrating spray and hours of tapping it with a hammer will release any stuck bolt now he did say it took him a few hours of spray hammer spray hammer he did it on a couple different old rusted things the other day

When u we’re removing the main engine bolt (frame bolt whatever) with the hammer then u tried the impact hammer u were struggling but what I do is I use the claw of the hammer and it doesn’t slip. Just bang it out with that.

The 2004-2005 models had a known issue with oil starvation and they fixed it by doing an “oil mod” make sure you look up how to find it and see if it has the oil mod done

Forbidden glitter and rainbow steel! Things you never want to see. Lol

You are more gracious than I am. This guy would have driven me crazy. I would have walked away.

Thought you would pop that rod cap off, check the journal and show us the destroyed bearing

Someone must have done an oil change and got busy and forgot to add. One way to cook an engine is to run out of oil. Good thing the crank stopped it before anything else got damaged.

You are going to want to install a 07 450 oil pump,inner clutch cover and wrist pin squirter. Look up oil pump mod for 04 to 06 yfz450s. Crank failures are common for these years. Yamaha cured the issue in 07.

Just had the same problem on a Raptor 700 I got. The Rod bearing was seized just like that because the previous owner ran low on oil. Rebuilt it with a Hot rods crank and now she runs good. I have a video on the tear down.

Every time u buy a machine take us with! It’s cool to watch

If it's aluminum tab you can build it up.& Remake A tab.

I have a 06 yz 450 with the 5 valve head. There's an upgrade that adds an oiler tube to get more oil to crank-if I remember right. I think the upgrade was later years that are compatible with the 06. It's a small tube that spits directly into a passage way.

There is a video out there called important information for 2004 through 2006 YFZ 450, go look at that it has something to do with the oiling system on that bike you might as well fix it while you have it open

You can thread the inside of the swingarm bolt, thread a lenght of all thread into it. Then slide a large socket over it, large washer and a nut. Then start cranking it down to slide the swingarm bolt out. I hope that makes sense.

The thing is going to be a beast! Can’t wait for the day you get to “take it for a rip”.
