Does anyone have a Left side engine case half from a 2004-2009 Yamaha YFZ450 that's in good condition?

Thank you for the support!
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.
@@benjamindavidson632 yeah I was worried about that. I think the best option is to just find a good welder and weld it up.
@@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.
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.
Could you get a LTR450 sometime?
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.
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!
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.
credit on the patience you have
You know Exactly what to do... It's not even a question you fix it... Sorry but it's the right thing to do...
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
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.
You made the right choice. And you do it yourself. Good stuff.
I can tig weld and Im not a wizard. Its a skill that can be learned. I did it for 12 years. Its fun.
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 💯🏍💨💨
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
I love my 2006 YFZ450, never been beat by anything in the same category
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
The warrior in the back🥵
Very impressive video, great workmanship.
Awesome quad!
Awesome video man
Nice little project there Joe. Hope you can find a reasonably priced case half or set.
Dzm bro u made quick work pulling that out
Sweeeeeeeet quad. Love your videos.
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.
YESSS FINALLY A YFZ AGAIN
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?
Might as well do piston rings and valve seals while its apart too
I think you made the right choice joe save that Yamaha 👍👍🤟
You made the right decision.
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 👍
awesome video buddy
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
No space for a work bench
Drives me nuts how he works off the floor
I bought a bike a while back and a week later I had to put $1300 in parts in the motor and clutch🙁
Yes always do it right! Thats a nice machine too.
Find a good heliarc welder who could weld it back together.
More money in your pocket fixed right. Like your video's. Been watching for a while.
Good choice buddy. Î given a lot odds shit sometimes but you made the right decision relaxing the case
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
You have one of the best quads,besides the raptor.
big up from 🏴
When you get this running I will subscribe.
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
I used to live right near EAA airport! The planes drive you nuts. haha!
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 .
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.
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?
R u selling quads after ur done with them???? Just wondering. I sure do like yfz!!! Great video!!!!
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...
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.
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
Why wouldn't you pull the whole motor then tear it down on a bench
Because when you have jb weld and wd40 you don’t need a bench because all great mechanics work on the floor lol
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
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.
Yeah looks like i might have to find a welder who can do it.
once the yfz450 is fixed you should do a 450cc race between the yfz450 and trx450.
Every time I see this motor all I see is that witness sketch of Walter White from breaking bad lol
If oil comes out, water can get in. Does it have oil nozzle for the piston?
Looks like u need new sylinder as well.. The nickel coating is worn by looks of tHt?
Joe...why did you do this work in the parking lot of an air show? 🤣
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.
So why go that way when you could just weld it and save hell of money
I have a problem with oil getting into my stator can this cause my bike to splutter cheers
That casing looks familiar 🤔 did u sell it on ebay
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
How'd you fair in the storm last night?
Sweet
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
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.
i have a 1997 yamaha warrior got it running and was running good top speed was like around mid 60 then i started hearing like a rattling noise on the left side and my quad has never ran the same. does anyone know what’s the problem
So is it better to buy a dirt bike, or quad?
is it faster the quadzilla?
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
13:30 to 14:06 made me want to go have a piss 🤣🤪😂
it made me crave mtn dew
Is there a video from that old Puch moped. I Just cant seem to find it on your channel.
Yes there is
Much awesum
That sucks dude. This happened to my 250es once when the starter gears went.
Flywheel prolly fine looks like the stator bolt that u pulled out
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
Just the same as any other quad. Regular oil changes/maintain them and your good to go.
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
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.
@@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
You can Rewind stators
2v time let's goo
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.
I had a 08 450 about three years ago and that sure looks like it lol.
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.
@@caseygillis5347 literally the exact same thing happened to me
29:18 easy fix with a dremel. Do it before you put it all back together.
👍
Order in a DRW case saver for it. Save the new half from it happening again.
yoooo I recognize your profile pic from the 400ex group on Facebook haha
@@mixxedboyybuilds8273 Lol yup that's me. In a pile of wheeler related groups. Mostly Honda.
@Aaron Lasnoski good seeing ya on here brother, don’t know why, but it surprised me 😂
Pretty soon you'll have your own shop maybe dealing new motorcycles keep up the good work
Do jb weld bro
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
200$ to have the peace of mind knowing that you aren’t going to grenade your engine is definitely worth it IMO.
It’s a M33x1.5MM
do a top speed
That’s why I own a Honda
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.
Weld it or replace the case do it right don't cut corners man thats not right to do especially if intend to sell it
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.
🙏🏽🙏🏽👍🏽👍🏽💯👏🏽👏🏽
U could have someone weld that peice back onto the case
I'd get the case tig welded and machined, if needed.
Weld it it gone work just ass good
When are we going to see the Tecate 3
Jb weld
Them bolt go to the flywheel
What a pisser mate can't win them all but maybe a good welder could do a decent repair save you some cash other than that a lot of good people on here can maybe help you out good luck and take care 👌🔧🔧🔧🔧👍
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
that piece is an oil seal, its essential

Cylinder is done like look at it worn the Plating off
