- Whats up Guys! I bought a $600 2009 Yamaha Yz450f and took it from crappy condition to pristine beauty, I had to replace the main cases, jug, piston, crank, and many cosmetic pieces. It took me a while to finish it but it was well worth it! Like and subscribe for more content. SORRY for the last muted part, the song turned out to be copyrighted.

I had one of these demons as my first bike... brings back good memories to see you working on it. Thanks for sharing!
Sick Rebuild!!
Just finishing up my 2008 yz450. Motor was a few rides away from grenading. It's been a bit of a battle. On top of a full rebuild it was neglected in almost every other way. Almost every bearing, seal, cable needed to he replaced as well as bunch of other little things.
But there is nothing better than bringing a bike back from the dead.
I brought the exact same bike a few weeks ago with the intention of rebuilding it but it turns out it had a major rod failure completely snapped the balance shaft in half and destroyed the casing. these model engines have a large oil cavity around the crank and if something comes loose inside normally it gets smashed to bits. its been an expensive build so far but ive learnt so much from it
Yes!
Great job you have an awesome bike ..built by you! Be sure after break-in at 1st oil change to get a quality full synthetic motorcycle oil in it. 10w40. Maxima Pro Plus or Mobil1 4T racing are hugely popular! #Maxima
You are a great mechanic!
Awesome job!!!!
Nice work 🤘
This one came out sick!!!
Built From The Bottom thanks bro! Definitely one of my most favorite builds!
Another awesome rebuild, heck yea bro
Jonathan Bizilia thanks bro!
😮😮that was pretty cool when you was testing the motor never knew you could do that
I noticed you hitting the bearing in with a mallet. I learned from others to use old bearings to tap in. Perfect size without the risk of damaging new bearings.
A "back yard mechanic" you may be Benjammin - but your skills and attitude would put many professional mechanics to shame! A fantastic build and transformation - thank you as always for sharing!
Lol thanks bro!
Big shout from Scotland awesome as always bud
Whatttt up, Thanks bro!
Awesome as always bud great job. Would love one of your bikes. Usual big shout from Scotland 👍
I have the yz250f 09 in the white and it’s an awesome bike
Well done sir well done!!!
Yamaha YZ 4-STROKES are excellent bikes & well worth the time & $ to fix w/finest parts!
Nice work 👌
My bike is next what time and location lol...good job bro nice video I enjoy watching this
Really nice job like ever bro, it was insane, cheers and blesses
Thanks!
Just amazing
Buen video capó. Saludos de 🇦🇷Mi duda es de donde sacas electricidad para el faro de luz
Perfect🐐
A little bit late but damn what an awesome rebuild! Seems like the previous owner liked to beat the s**** out of that engine, incredible...
Good job. Only suggestion is if you are going to drive the new case bearings in by hammer, then atleast use a bearing/seal driver to do so. Preferably one that is brass or aluminum. Do nice centered flat blows. And oil them ever so sligtly around the race edge and case mating surface. Also if installing some other way than i described you should do the best you can to focus the driving downward of the bearing by tapping around only the other race. Our evenly across the whole surface. If u drive it in by the inner race you can chance completely destroying or badly damaging the integrity of the bearing and may not even see it realize it until its to late..
Thanks for the advice, I’ve learned a lot over the past few years and since then I’ve bought lot more tools for the job. This was my first rebuild and I made a lot of mistakes.
Not a big fan of spoke covers, and a restyle front fender would really set it off... Ask me how I know. lol. What was the total spent in fixing it up?
Excelente job
Good job. Just a little tip for Installing bearings is to freeze the bearing and heat the case and you will never have to beat them in with a hammer
I did freeze bearings and heat the case and still had to use the hammer.
Did you say T6, as in Rotella T6 oil?? when you were lubing the cam and timing chain?
How many pounds of torque are given to long screws?
Did you use 3000 paper when you got into your swingarm
Fantastic job! (and video)
Thank you for posting it!
Great vid! One question though, what did you power up the headlight to?
I got a battery pack.
hey man how much did you pay for a new set of cases?
Spoke covers ain’t it and grips are cheap that’s my only quarrel other than that love watching you bring an old beast back to life
I’m doing the same thing to my yz450f guy before me blew the crank on it
I have a 2o19 model really nice machines
Oh wow! Such rebuild, much fix, very bike
Very solid build hopefully i can pickup a 450f project like this soon. Thought i bought a deal on one but seller doped me and sold me a 250 lol
you don't need to have a bike if you cant tell the difference between a 450 and a 250
@@iltgpatged yeah didn't notice the upped sprockets when i test drove it. You are right, I'll stick to the 150's.
Little late to the party, I have an 08 250f and bought it with those exact same graphics on it. After some time they started to peel. I’ve been looking for them for months across different websites. Did you get them off of eBay?
Nice job. Where did you get your headlight from? Was it plug and play, or did you have to splice wires to get it connected? Im looking for a headlight for my yz450fx and that looks like a great solution.
Thanks!
Thanks! The led bar is from eBay and had to get an external battery pack and wire everything thing. This specific yz450f apparently couldn’t fit a stator with a auxiliary power for light on it so had to go with external source, which I bought a “dewalt battery power dock” on eBay for like $16
Ya
Ya
i didnt think that light bar would look good, but SHEESH!
Yeah It looks really good coming through the number plate!
installs sylinder and piston whitouth oil, thats good for sure..
Yeah that wasn’t good. I lubed everything in the bottom end but failed to lube the piston definitely a dumb mistake.
Awesome rebuild! You gotta get the TDC before kicking hard and wasting your energy
Just past and you can do it in slippers
Did ya lube the cylinder and check ring gaps?
Great vid btw.
I did not, those were some mistakes I made.
Where did you get these graphics they give the bike a clean alternative oem look
Thanks! eBay
Nice
How did you get the cam chain to go on so easy. With an oem chain and the tensioner removed its still tight
You kind of have to put one cam in at an angle, it’s a little tricky
Wait what? You just pull the seal down farther or something in the forks? If they are deteriorated tho, it will start leaking again
The biggest reason for forks to leak in my experience is been stuff between the seal and the fork tube itself, like dirt which causes the leak.
Hey I just bought a 450 and I was just wondering what years is the front fender and plate
This is a 06-09 body style, I’m not sure what other years it’ll fit.
I hope you didn’t forget your cylinder coolant dowel and oring. Looks like u didn’t put it in
I didn’t, don’t worry lol
hi, can you just tell me what was the link or name of the light that you mounted on
Not sure but it was just some eBay 7” single row led bar.
Where do you bought that red levers?
eBay!
Where did you connect the light please?
I didn’t yet, I was going to wire it into an external battery pack system.
Im a beginner interested in purchasing my first dirt bike. debating whether a Honda crf 230m or ktm and yamaha. Any help?
The quick answer is Japanese (Honda, Yamaha,Suzuki) they make great bikes, But ktm is nice too. Biggest thing is just doing maintenance on it regularly to make sure it runs good for a long time.
@@Benjamminoutdoors thanks
Maybe look up the correct way and order to tear down and rebuild. You apparently have the tech manual. Top end should be the last thing to come off. And use a bearing press for removal and install- never a hammer.
Have you rebuilt a dirtbike motor like this? You HAVE to remove head first and install last and you’re right I should’ve used a press but I didn’t have one.
Dude you just need a white seat cover and then you’re golden
How many pounds are given to screws holding the head and cylinder?
I can’t remember, if you Google it you can find it
@@Benjamminoutdoors All how many hours do you give me service to your bike?
Can u help me rebuild my Yz450f 09
Hi where did u order the parts from
eBay!
@@Benjamminoutdoors what crank did you go with? I see ebay has hotcams and wysco. How's it holding up?
Well done! Shame about the chain though...
What do you mean?
@@Benjamminoutdoors Not big fan of this red chain, would like better in normal colour combination.
czerwiec04 I got you, I was just going for as much red as I could I wanted to do all the engine plugs red as well but the kit was like $300 for a couple anodized red pieces 😂
I wonder why there are so many different bearing installation tools out there?
When you can obviously just use a hammer or mallet, I mean, everyone has a dirty old persuader lying around somewhere.
lol I’m not in love with the hammer way… I much rather have a press lol.
Anybody else lose sound at the endish of the video
How much it cost you?
Way too much lol
Total cost please??
A lot 😂
I have mixed emotions... I appreciate they rebuild video, but maybe I’m missing something. Did you check the shims after you tried kicking several times and turning the engine over with an impact gun or was the video editing wrong? And the carb should definitely have been looked through before kicking the bike over, I mean you were starting with a bike that had debris inside the head... Thanks for your efforts, I know doing this is not easy, but a disclaimer to viewers may keep some from making a mistake if they are trying to learn. Good luck in the future!
Yes I did a valve adjustment, went through carb and the head was clean and I showed all that in the video.
Crank bearings are ruined never hammer them in and that cam chain is junk
Just a question.... Why buy new plastic, when there's nothing wrong with the old ones? Again just a question
Because they’re very dirty and very scratched The whole point of the video is to restore it.
Oh.... So too lazy to clean and restore them... That was all you had to say.....
@@evasanders7327 Yup exactly, the plastics are cheap what can I say. And are you not gonna respond about the YZ? Did you Google it yet?
@@Benjamminoutdoors lol.... Anyone can do what you do... Buy the parts and put them together... A true restorationist uses what is on the bike and repairs and restores them...... Call it what it really is a factory rebuild....
@@Benjamminoutdoors check out the channel "Restoration channel" that is what a real restoration is like... And who doesn't have Google and still I didn't need it to know this...... You should change the channel name to idiot rebuild channel.... Just saying
Some one can help me buy motorcycle like theis please
$700+ for the rebuild and you couldn’t spare $30 for the case gaskets?
From the factory they do not come with the gasket between the main cases, so I do not put one between the cases because that can ever so slightly put my connecting rod off center and can potentially not let my cylinder jug fit on properly. if you don’t believe me you can go to the Yamaha parts and look at the images, all the covers have gaskets but the main cases do not.
Dont wast ur energy kickint it like that, find the TDC first
Nice job, but you shouldnt be reving the bike so much till the engine is broke in
depends on who you talk too about break in technique, But it doesn’t help I’ve owned this for over a year and was dying to ride it finally.
@@Benjamminoutdoors reving too much can twist the rings and destroy it, may cause scoring on the cylinder wall too
after going through heat cycles it doesn't matter
Nícolas Piano I’m well aware of what can happen. And while it looked like I started it up and immediately ripped the throttle, me driving it was not the same day as me cranking up the first time.
junk it befor you get to deep
Do not do that to your forks that’s a temporary fix and they will just go bad again just rebuild them
Why not? It doesnt cost anything and doesn’t hurt anything. I’ve seen fresh rebuild forks leak after ridding some so I’m not ganna spend the extra effect if this works just as well.
But it doesn’t work as well I destroys my forks doing that but that’s what happens to me
Britmaster 1 Every time I’ve done it it worked well, and if it doesn’t work then I’ll do the forks seals but it doesn’t take much time and doesn’t cost any money so why not try it first.
What ever works for you it just hasn’t for me sorry if I came across mean I’m not trying to be by the way love the video I’m buying a 450 soon
Britmaster 1 nah you didn’t, and nice! It’s crazy power out of these 450s!
Also that is not a YZ.... All YZ motorcycles are 2-stroke cycle engines.. and that's clearly a four stroke cycle engine. Just saying.... lmao
Lol Google is free bro. Google YZ450f…..
I'm not a bro.... And I've rebuilt motorcycles since I was 10..... I don't need Google to know a YZ motorcycle doesn't have a camshaft or standard valves they have Reed valves..
@@evasanders7327 Lol you obviously have no idea wtf you're talking about.
You overpaid at $600
I know that now lol I didn’t know it was as bad as it was
