Dude!! I just found this same bike on Facebook Marketplace for 500 bucks. The thing is, I'm pretty good at this sort of stuff. He took this bike on a trade-in with the rod knocking like crazy. He tears down the engine, yeah, split the case and for some reason (lack of funds or lost interest) threw everything into two big ass boxes, shook up said boxes for good measure. Took pics of bike enginless from all angles, good rubber, chain looks good, suspension looks good, etc. (didn't include pictures of the two boxes of lose cases, bolts, nuts, (even took the head apart for some reason) a cam here a timing chain there. literally, a basket case! All I know for sure is the bottom end needs work. I'm not sure I want to dive into this gene pool. Thanks for sharing your hard work and expense. Cheers from Louisiana.
Top Tip- Keep a hobby brush or similar brush around for lubing up your engine as you assemble the parts, just dip the brush and paint that oil on instead of fiddling with the cap and getting all oily. Keep up the great work!
Nice one Mason , you scare the crap out of me though using power tools on an engine stick with the hand tools for that lad better safe than snap bolts or strip threads .can't wait to see it start
Its fun watching you learn stuff for the first time. Shrug off those negative comments... Are you making mistakes...probably but your learning...ive seen you grow over the last year and good on you for tackling all this and letting us come along!
Well said man! A lot of "race engine master mechanics" in here armchair quarterbacking & ragging on the kid but Im happy he's getting his hands dirty and out of his comfort zone. More than you can say for 99% of kids coming up now days. The only way to learn is to make mistakes.
I like what you're doing bud. But do some studying on the specifics of building these race motors. For example, unless you're just trying to get the most power for one race before you have to shim again, you don't want to be on the tight end of spec when shimming valves, you want to be at the top of spec, also if you are running a 1.50 shim, whoever buys that bike is fucked. The valves have beat themselves deep into the seats and it's time for a valve job. Also when you are checking clearance, the lobes need to be pointed away from one another at top dead center, not vertically, and the cam caps need to be torqued to proper spec before checking clearances at all or you could get a false reading.

Same page brotha....thank you for saying something .....I couldnt finish the vid... I thought it was a joke of some sort...then I kept watching ...got the feeling in my stomach after you kick a bike for the forth time and still no light ....ya ...hit me like that ...lol
Great job...I'm looking to buy a 2008 yz450 that has a big hole on the side of the engine and was very worried I'd be in over my head and after watching this video I was rite!!!....(still going to get the bike and see how bad I can screw thing up)....see ya
That's an automatic cam chain tensioner when you wind it in all you have to do is tap it and it pops and the spring pushes it back out. So wind in and fit thwn tap and it pops to the cam chain guide to the correct tension.
Fingers crossed ,that's the only prob with the newer style engine sweet F.A for tolerances and big bucks on failure ,bring back the big 2 strokes blow em up couple of hundred to fix at home.
Are you sure about the torque? i saw Nm not Ftlbs!!! big,big difference, that could be why you snapped the clutch bolt! they're something like 7Nm and struggled with the head torque!
He put in way more than 7lbs anyway, he really put a bit of effert into tightening them, same with the caps for the camshafts and the bolt/nuts on the left side on the cylinder.
@@JensEskildsen yeah i think he's getting confused over Nm and Lbs, think that's an old wrench, looks like it only has ftlbs,most modern ones have both, but some don't go low enough for clutch bolts, i hope he reads these as i'd like him to back off the cam caps.
he might just be converting directly people with limited tools are just forced to not be lazy that's probably why he wants a digital and not just a new one
Dude, you need to take a scotch bright pad on a drill to the steel plates on both sides.Scotch bright paddle clean him right up and take the glazing right off without removing too much metal in minimum effort on your part.
Dude, you have to check the valve clearance.You just can't bolt that up and let it go.You gotta make sure you get the right chins under the shim buckets
I was planning to sell my KTM 525sx today and get a 2003 yz450f. But after seeing this video how to adjust the valves I think i'll pass. It's so much easier to adjust the valves on the 525sx. All you have to do is remove the intake and exhaust cover on the top.. And thats it. You to not have to remove the whole freaking top to adjust the valves. Just leave it on there. To see if you're in top dead center you just remove the spark plug, Put a long drinking straw in there and kick the bike with the highest gear until the straw literally ''shoots'' itself in the air. Wiggle the rear wheel a little bit back and fourth to see if the valves are moving. They don't? There! Now you have top dead center. Now you just grab a 10mm wrench to loose all the four nuts and a 0.12mm feeler gauge. All valves are ''and'' should be 0.12mm. It's simple, It's fast and it's alot less parts to look out for. Idk what the f*ck Yamaha was thinking with this engine.
You should eventually do like a staple Gold Guy build. Make it badass and put your logo on it make parts gold or gold and black or something I think that’d be badass
Would definitely recommend filing or replacing that clutch basket had to replace mine about 3 months ago as it would just keep stalling when it goes in gear good video though
My recommendation after having had similar problems: Use smaller torque wrench for smaller screws. It can be adjusted more exact at range of lower torques and also reacts more sensible. Love your videos and how you get better with each built.
@@HI-mk7gw I agree with you ...but there is alot of people that watch you tube and come here for information that dont know the difference and look to creators for guidance...and if someone followed this ...there maybe decent motor would be crap in no time ....
Stating the obvious but time for new torque wrenches. I got a 1/4 drive one for the smaller stuff and found it much better especially when it comes to over tightening. .
Hey man not to knock anything you’re doing but something I noticed that could make a big difference with your torquing. You’re using your torque wrench like a ratchet once you torque something down with it you do not loosen it back up using it just something I learned from working in a dealership
Maybe I'm wrong but isn't there supposed to be 2 chain guides coming up through the head?I only see one coming out of your head.So did you forget to put one in or does a Yamaha only have 1 pretty?Sure, it's supposed to have to though.So he might wanna look into that
Thanks for another video Mason. Keep up the good work. The instructions said to put grease on the valve train parts? Seems like just a little assembly line would be good.
Good luck to you, I'm excited to see that bike rip! I'm currently rebuilding my Honda XR250R engine and will hopefully have that sum bitch running next week!
All I can say is you have a lot of learning to do as far as working on dirt bikes. Very first thing you need to do is get quality tools to work with. Your torque wrench is shit and need a good one. All in all your doing ok .
At the stage where nerves start kicking in when close to start up then you find a circlip that your pretty sure is important,lol Jokes aside whats the cost so far I just got my 08 crf450 redone gearbox to top end $3100 .
Legos Trains & More thats what I was hearing when I went to replace my clutch, people were saying at only 8ft/lbs they were snapping bolts so a lot of guys just said tighten them by hand. Its working for me for now
14:20 should of covered the crank from debris also your torque wrench is wrong, it's too old, use a rag to put on the surface when using a screw driver to remove a seal, make sure you have the right assembly line, some can mess up your clutch, that's why oil is recommended
You didn'. T even shin the cam.This is why people like you shouldn't be working on a motorcycle engines without having somebody.That was the hell they're doing with them
Oh my word, the amount of abrasive and metal crap left in that engine after removing the shift rod... This is why you don't buy used unless you are prepared to inherit someone else's fantastic incompetence. I am not saying don't buy used just don't buy used if it is a bike you are positive you want to own for your lifetime.

That's an automatic cam chain tensioner when you wind it in all you have to do is tap it and it pops and the spring pushes it back out. So wind in and fit thwn tap and it pops to the cam chain guide to the correct tension.

For a young boy, in my opinion, he did the renovation quite well. Greetings :).
Make sure the assembly Lube you used. Does not have friction modifier in it or it will ruin your clutch. That's why they suggest using oil
Frikin awesome man. And you think it might blow up, yeah right. Dude this thing is gonna scream!

Those buckets are specific too. They gave s color code under them. Do not mix them up

Oooh private mx track, I'd love to see that place sometime

I couldn't watch past 4:47, if you are going to show 43 thousand people how to rebuild an engine I think it's your duty to use the correct methods. gl
I think He overtightened the caps also , so that is toast
I about died....poor motor!!!..lol

Don't use a big torque wrench for small bolts into aluminium, just do it by feel with a small ratchet
You deserve more subs and likes
Stating the obvious but time for new torque wrenches. I got a 1/4 drive one for the smaller stuff and found it much better especially when it comes to over tightening. .
Not gonna lie I was stressing out when you were angle torquing those bolts... Haha nice job!
Me too, but for the torque wrench. Should have been done with a bar
Right on Gold
Did you pay attention to spacing your rings out so the gaps aren't lined up by accident
Can't wait to start that beast! Great vid bro 👍

I had to cut the rod exactly how you did haha it was not fun but I did it on a yz 125
if u dont have a good idea of the yield of bolts by size before snapping dont bother using a torque wrench.

I really enjoy these videos!
When can we expect to see the new video?
I can't wait
Better late then never!! 👍👍She going to purr. 🐱 good work
Not sure if I seen it in the clip "which great effort btw" but! Did you you check for the correct valve clearances? 😁👌
Man what you doing using impact driver on those caps might as well use a jack hammer champ

I did the exact same thing with a clutch spring bolt. Torqued it down and it broke right off
Legos Trains & More thats what I was hearing when I went to replace my clutch, people were saying at only 8ft/lbs they were snapping bolts so a lot of guys just said tighten them by hand. Its working for me for now
Blake Bolte luckily I had extra bolts on hand so I managed to torque them all them down without issues
Legos Trains & More thats good to hear, i didnt have any spares and got paranoid i would snap one lol
13:06 did the exact same thing when replacing mine😂
Its gone b ✔ done soon🙏🏼 n looks good
Front where You save all this diagrams and specs dates? I mean you buy from somwhere?
Did anyone else not notice he never put the second cam chain slider in
Can u take the head off without removing the cams? Say if I just need to change my crank case
Nope, the cam chain holds the head/cams to the crankshaft.
14:20 should of covered the crank from debris also your torque wrench is wrong, it's too old, use a rag to put on the surface when using a screw driver to remove a seal, make sure you have the right assembly line, some can mess up your clutch, that's why oil is recommended

@@GoldGuyRides Thanks men. Saludos from Spain, I wish you the best!!!!
Anytime you torque something it should be a smooth linear motion not jerky
How many pounds of torque are given to long screws?
What guide were you looking at on your phone?
How many pounds are given to screws holding the head and cylinder?
What service Manuel are you using
You used a power drill to tighten the cam cap bolts?? You need to do some research.
Powerdrill is fine...as long as you set the torque in 1. position..
