Does anyone have a Left side engine case half from a 2004-2009 Yamaha YFZ450 that's in good condition? Please SUBSCRIBE and LIKE the video if you enjoyed! It really helps me out a lot! Check out my Instagram: 2_vintage_ Thank you for the support!

[@benjamindavidson632]

The cases are machined together. You CANNOT use a used one unless you buy a matched set. Clean it very very well, give it a few good tacks and use jb weld or your metal repair of your liking.

[@2vintage]

@@benjamindavidson632 yeah I was worried about that. I think the best option is to just find a good welder and weld it up.

[@unchained20000000]

@@2vintage Yep. Sometimes being a perfectionist cost too damned much, just to look cosmetically attuned. When getting a welder that knows how to weld aluminum is all it needs to work like new.

[@K_Bendel]

Been in this same predicament myself, where I replaced the case with another used case and it would leak oil and cause all sorts of issues for me. You’re better off using jb weld and just applying it properly.

[@rustbuket6159]

Could you get a LTR450 sometime?

[@fullmetaljacket7]

Just weld that case and you'll be good to go. Also, you can rewind the stator at home if you have enough time and patience.

[@NewBeRVer]

I’m glad you made the right decision not to do a half ass job! Definitely adds credibly to you, the work you do, AND your channel!

[@copperaudio9664]

Indeed. Stay far away from any engine fixed with any kind of structural adhesive. It never lasts as evidenced by Joe's trouble with it. Do it right the 1st time.

[@jodyhakamaki5602]

You know Exactly what to do... It's not even a question you fix it... Sorry but it's the right thing to do...

[@mikestowe6136]

credit on the patience you have

[@stopcensoringmyfreespeech3280]

I can tig weld and Im not a wizard. Its a skill that can be learned. I did it for 12 years. Its fun.

[@markhensley9378]

Personally, I think you're doing the right thing by tearing down the engine and replacing the case half. In the end you'll have a new case saver and you might even find a few more problems that need addressing.

[@ikillu2100]

I bought a yzf and guys stated it was the stator ended up being the coil pack had a hole burnt threw it taped around it she fired up ordered a new coil and got it fix excited to see more videos on this quad so I can learn more on it

[@minimoto123ful]

I have a crf250r 2007 and there person who had it before me had the chain pop off and do the exact same damage as your engine case got it welded up and works perfectly save you a lot of money getting it welded 💯🏍💨💨

[@Peedarb]

I love my 2006 YFZ450, never been beat by anything in the same category

[@grandpa-of-3898]

You're doing it right take it apart and fixing it maybe look around and find someone to weld it or finding a good replacement and check the rings wasn't it smoking a little but really glad to see you doing this it makes you and your videos great

[@JamesDavis-to1hn]

You made the right decision.

[@andrewspoto9378]

You made the right choice. And you do it yourself. Good stuff.

[@jasonward9559]

While I had it all apart I would do all the seals amd look over taht crank and bearing real good that year has the oiling problems unless its had the oil modd done keep up the kool content brother

[@CraaaigV302]

Might as well do piston rings and valve seals while its apart too

[@sootie620]

I would have fixed with alloy based epoxy resin then sanded it smooth, that stuff is unreal and done properly is barely noticeable unless on very close inspection. I’ve used it on a 350 engine and it’s still as good after 12 years, no leaks no nothing 👍

[@jasonhendrie5411]

I think you made the right choice joe save that Yamaha 👍👍🤟

[@Goldhunter-vt8ww]

The warrior in the back🥵

[@bryantucker1270]

If ur going to fix something fix it right the first time then you don’t have to worry about it a lot of people would have just jb weild that and go on when buying cases it better to by both sides Bc there Mats and seal better. Great vid

[@george31380]

I hope you know about the oil mod in the o5 and o6 yfz450. Also there is a stock cam mod to adjust the exhaust cam1 tooth clockwise on the timing chain its good for a instant 2 HP. Also to help your clutch last longer for higher HP motors install 3 stiffer springs in the clutch or just do all 6 it also prevents slipping. The indents on the clutch basket, file those down so the surface is smooth instead of a ridges = smoother clutch operation.

[@samuelgagnon4953]

YESSS FINALLY A YFZ AGAIN

[@toothfairy2353]

Very impressive video, great workmanship.

[@c0munguyforcaz]

Awesome quad!

[@gtisid]

Thats the sort of kick in the balls i get when i buy a bike. i like the idea of doing things properly, it makes it so much easier to sell, but it does look like a horrible job to do and for the 20 extra minutes it will take i would be replacing the crank bearings for peace of mind. maybe a parts washer would be a good investment and a work bench you cant keep floundering around on the floor

[@insiderate]

No space for a work bench

[@chadcaudill509]

Drives me nuts how he works off the floor

[@tywomack4411]

I bought a bike a while back and a week later I had to put $1300 in parts in the motor and clutch🙁

[@Davido50]

Yes always do it right! Thats a nice machine too.

[@andrewspoto9378]

You have one of the best quads,besides the raptor.

[@CraaaigV302]

Dzm bro u made quick work pulling that out

[@Noslo_559]

Nice little project there Joe. Hope you can find a reasonably priced case half or set.

[@jamesbarrineau8769]

Clean up around the hole good and seal it up with JB weld, and you should be fine until you get find a case. I had the same problem with my yfz, flywheel bolts came out and messed up the stator.

[@kennethhetrick5458]

If you jb weld it cut your self out a small piece of wax paper and cut it to fit perfectly over the shiny part that you don't want the JB weld To stick to or go down in that hole...you can hold it in place with a small dab of grease...

[@m8fusion712]

Awesome video man

[@NorthFloridaOutdoorsman]

I worked on alot of atvs and dirtbikes, I hate this motor. I had a 450 that I rebuilt and worked on , it was a pain good luck man

[@thor942]

Great video as always. I just noticed how you show the camera the parts as you take them off. Do you do that to retrace your steps for reassembly?

[@MM_in_Havasu]

Find a good heliarc welder who could weld it back together.

[@cheto2952]

Good choice buddy. Î given a lot odds shit sometimes but you made the right decision relaxing the case

[@jasontodd8922]

Sweeeeeeeet quad. Love your videos.

[@snoopysrc]

awesome video buddy

[@chuckfinley3152]

Find a good machine shop with a TIG wizard and they can weld thin cast aluminum and magnesium easy peasy, there are shops on the inter webs that specialize in case repair too

[@ItsProbablyFine]

I used to live right near EAA airport! The planes drive you nuts. haha!

[@chrisbenjamin417]

More money in your pocket fixed right. Like your video's. Been watching for a while.

[@dabsoffunk2587]

I got the same problem i have an 05 and the chain snapped the shift shaft out of the case, i guess i gotta just try to have it welded up

[@sulmyhernandez8503]

once the yfz450 is fixed you should do a 450cc race between the yfz450 and trx450.

[@bigcaputo09]

That's a mean looking 4 wheeler!! I think you should replace the side cover as well!! Didn't you have no spark at first also? Then it worked? When you first got the 4 wheeler?i can't remember?

[@BitcoinYooper]

Go on partzilla. Those cases are matched and sold in a pair. Show's in stock for $347.64. Going to have to do bearings tho.

[@Guadzilla459]

So why go that way when you could just weld it and save hell of money

[@ni_wink84]

It’s an expensive fix, but considering prices on new bikes, might be worth the investment? Especially if you like it and want to keep it

[@colinculverwell325]

There is a reason Yamaha don't sell just half a case. They are machined at the factory as a pair both at the joint face and line bored for the shafts. You could get away with it or just be making a whole new problem. Just get someone to weld it. Got to be someone in your area that does that sort of work. Dont have to do everything yourself, no shame in outsourcing specialist stuff.

[@2vintage]

Yeah looks like i might have to find a welder who can do it.

[@krotchlickmeugh627]

Gotta get a set of cases. They are a machined mach. Also next time you are trying to take a cover off like that stator cover. Smack it with a rubber mallet a few times. That way you save the gasket

[@exCR-it3ex]

You can Rewind stators

[@brandovillasenor8049]

If oil comes out, water can get in. Does it have oil nozzle for the piston?

[@Bri-tg6xr]

That sucks dude. This happened to my 250es once when the starter gears went.

[@pedromendia152]

Hey vintage I got a question so my 05 yfz 450 worked good then after I road it the thing just shut off and whenever I press the start button it does nothing and when I switch the kill switch on I don’t hear a click or nothing I could use some help please .

[@smarquardt10]

R u selling quads after ur done with them???? Just wondering. I sure do like yfz!!! Great video!!!!

[@mattrides248]

I had the same exact problem with mine where my chain flew off while riding making a big whole in the engine and I have the exact same quad but I had to replace almost the whole engine costing me over 2k

[@CraaaigV302]

Flywheel prolly fine looks like the stator bolt that u pulled out

[@sawyernanook3964]

Sweet

[@tylermason2072]

hey wondering if you still have that ltz400 im wanting to buy one and I want to know how you like it before I buy one.

[@jamieshepherd8995]

I have a problem with oil getting into my stator can this cause my bike to splutter cheers

[@jaygtgarage6489]

Looks like u need new sylinder as well.. The nickel coating is worn by looks of tHt?

[@adrianvogt2174]

This is the same thing that happened to my yfz, the bolts on the flywheel and the one way bearing came loose and all 6 broke off, I bought new bolts and had the stator rewound and then bolted everything together with locktite

[@FloridaMan0561]

How well has held up? Has it been a permanent fix? This may be a good alternative for those people who are unable to properly weld,and,or they can’t afford to pay a machine shop to do the job.

[@adrianvogt2174]

@@FloridaMan0561 I meant that only the bolts on the flywheel were broken, there was nothing needed to be welded and the motor case is still intact

[@KilroyMotorSports]

is it faster the quadzilla?

[@kiffersgarage9529]

So is it better to buy a dirt bike, or quad?

[@REMSTA777]

everyone starts at the small switches even shows on diagram to do the same thing, i think everyone should start at the stator first cause its going to tell you strait away if its little switches faulty sensors etc- immediately.

[@MC-lm9vs]

That casing looks familiar 🤔 did u sell it on ebay

I had a 08 450 about three years ago and that sure looks like it lol.

[@caseygillis5347]

The first ride on it not even five mins in I go to spin it around and the chain pops off and take off the edge of the case like this one. Also had a case saver and didn’t help.

[@unchained20000000]

I think you have everyone's solid solution to the problem, pay a professional aluminum welder to weld it. Pro job, without the hassle of trying to make jb weld work. That job isn't for jb weld.

Hey anyone have an idea why when I try to crank over my 06 yfz450 with electric start, it will crank for a little and then it will automatically stop while i’m still holding the button. I’m stumped and can’t quite figure out why it’s stopping itself. Thanks.

[@CraaaigV302]

Why wouldn't you pull the whole motor then tear it down on a bench

[@shaynedonnelly374]

Because when you have jb weld and wd40 you don’t need a bench because all great mechanics work on the floor lol

[@GiveItGas69420]

I would polish and buff everything while its all aprart gotta make it mint af and it could just be worth keeping at that point

13:30 to 14:06 made me want to go have a piss 🤣🤪😂

[@lol-fv7ug]

it made me crave mtn dew

[@im-that-guy-pal]

I would of tried to have the case welded first. Epoxies never last. I don't know why it cost $550 for a case side.. I looked it up and you can get a complete crank case for that price. Partszilla has the case half you need for 125.00.

[@did_that_hurt8387]

Every time I see this motor all I see is that witness sketch of Walter White from breaking bad lol

[@thatcoalminer275]

If you plan on keeping it awhile I highly recommend getting the oil mod done, 04 to 07 yamaha relied on the oil splashing into the bottom end and it caused damage to the bottom end due to lack of oil. I highly recommend it its cost about 200 to get it machined and you get a high flow oil pump as well, jtatv.com did my mod for me highly recommend

[@FloridaMan0561]

200$ to have the peace of mind knowing that you aren’t going to grenade your engine is definitely worth it IMO.

[@sandmanbub]

I'd get the case tig welded and machined, if needed.

[@Nebula-rx7bj]

How u been man, are 450s high maintenance? I’ve been looking at a second quad and I don’t want anything that’ll cost too much to maintain

[@jamiesmo91]

Just the same as any other quad. Regular oil changes/maintain them and your good to go.
