@@shaynebrown131Its something I came up with early on to help find the videos quicker. Like if I'm at the track and a buddy says hes going to do a top end and starts asking me questions I tell them to youtube search 1:11 YZ250 top end and it brings them right to the video. It just makes thew videos easier to find in a sea of videos.
I agreed to do one of these for a local track owner in exchange for riding free. It’s not as well kept as this one lol. I pulled the cylinder head tonight and noticed the intake cam wouldn’t turn freely. Exh valves are within spec but the intake has zero clearance. Decided to go to bed before going any further. Tomorrow I’ll pull the valves to see if the valve seats are worn down that much or if it was just shimmed wrong.
The only thing you got to watch out for on gasket. Sealant is on 2 strokes. You gotta make sure you're using fuel safe. Because the fuel touches it in the crank case. And if you don't have fuel safe gasket Maker, it'll eat right through that s*** But if you get fuel safe stuff, you will be just fine and then you don't have to worry about buying the Yama bond. Whatever bond you, James, bond f*** who cares?Just get some.That's fuel safe and you'll be alright
Your welcome. Its a little different for a brand new bike. I actually did a video on this if you are interested here is a link ua-cam.com/video/DdWL1OMpXyU/v-deo.htmlsi=qXbVNvcDmVqvRsgn
Upallnight dropping more knowledge!! Whoever said that about loctite is correct. There is a company that is making a similar product that is trying to counter whatever they’re doing I can’t remember the name rn but it’s in a white bottle
Probably Yamaha YZ450. But I will say the KX450 is probably almost every bit as reliable, except for the kx450 fuel pump recall lol. But otherwise it seems to be right there with the yz450 for the most part
@@stevemx2778 KTM is not the most reliable, I run into weird issues with them in weird areas. Wires coming apart behind the number plate (way to thin wires used) and also for the intake temperature sensor at the air boot, wires just break down there and need repairing. Weird stuff like that kinda put them behind Yamaha and Kawasaki in the reliability department. But otherwise the motors on KTM seem to hold up well enough
Ok a few things …. 1 - your Fucken awesome at wrenching and I wish you were one of my teachers when I went to mmi! 2 - thank you for doing these step by step videos ! If you could pop your face in next time to see who we are seeing wrench that would be cool! 😊 3- what kind of camera do you use to record this stuff if you don’t mind me asking?! 4- I been bin watching your channel 😂🤘🏽🤘🏽 keep doing what your doing ….- Andy
LoL. I do kinda try to keep my face out of it because I'm usually looking like a dirt bag in the shop lol. But on my latest video (CRF250 full rebuild part 2) I surely slipped my face in that one a few good times. The camera is just my wifes old samsung S7 phone. I surely need to upgrade to something better. I started this channel using that phone not knowing how things would go but at this point it might be due to upgrade. Thanks for watching Andy and appreciate the kind words. Since you went to MMI do you work on these for a living too? Did you go to the orlando campus?
With the built in auto decompression on the exhaust camshaft it is not easy to get a accurate compression test as the decompression bleeds off about 30 to 40% of the compression during the cranking process. But they need at least 90 PSI to start.
Sometimes they can be slightly hard to spin by hand when installed but will quickly loosen up right after the motor is started the first time. Its pretty normal
Assuming you been good with your oil changes you should be totally good going to 75 or 80 hours. I suggest 60 for a faster guy but even then the pistons usually come out looking well. Its more of a inspection of the lower end as well as keeping a healthy piston in there. For a vet rider, slower rider and up to about a solid B rider 100 hours is fairly safe. So you should be good to go.
All the? Motorcycle mechanics have to come behind you and take those bolts out with all that red locked tight on their ought to take that bottle of red and make you drink it
I share hope you are the one that has to take that fly wheel back off with all that red permanent luck tight on their only way that thinks coming off is with heat... Blue lock type would have worked just fine.I don't know why you use that red.Just makes it a pain i* t** a**Red is meant to be permanent, not temporary.It's not made for something.You're gonna have to be taken back apart at some point in the future...
Yes I will be the one removing it down the road. Yes it will come off ok with no heat. I do it all the time, daily, and for over 25 years now. No issues. I would not use or fully trust blue in high heat areas.
Your a bad ass thanks man thankful for people like you in our community 🤘🏼
Thanks Brother! 👍
You are amazing man
Thanks!👍
Whats the 1:11 in all your video titles?

LoL. You have good ears! 😂
Cheers bud i also have a 2021 kx450 iv only done 40 hours but this video will come in handy when I rebuild it
yes Sir!
You're welcome! And thanks for the knowledge of the Kawi 450...mine only has 12 hours on it but when it's time I know what I'll be watching again lol
Right on,!
A crafts man at work. Nice job 👍.
Thank you Sir!
Excellent video, thanks for sharing
Thanks Roberto. And thanks for watching!

Good catch and good call. I'm betting the valves have worn and sunk in, but you will know for sure soon enough!

Right on. I been using moto seal from permitex with success
That was incredible!
Thanks!
Great information! You're awesome I just bought a 2023 kx 450... I love it
Thanks! Awesome, congrats on the new 23 KX450!
Another awesome video 🏍
These are amazing bikes I have one
They are actually great bikes. Reliable and ride well
Thanks so much for the aswome vid.. is the run in procedure the same for a brand new bike??

Man I did not know that. Looks like I will be buying permitex tread locker
freekin Kawasaki with that alan bolt inside the cam compartment
LoL. Honda use to do about the same thing.
Good job
Thank you!
Weird I found my kx of the same year just like that with the valve clearance. Usually never have to go to a bigger shim size.
Right! usually they need bigger.

What's your views on de-glazing the Nikasil cylinder lining on a piston swap?
😂 ... If I feel it needs to be deglazed I just use fine steel wool and rub it clean by hand. It works well with a little elbow grease lol
I enjoy watching these long rebuild videos. Which current model 450 would you say has been the most reliable in your opinion?
Probably Yamaha YZ450. But I will say the KX450 is probably almost every bit as reliable, except for the kx450 fuel pump recall lol. But otherwise it seems to be right there with the yz450 for the most part
Not the ktm ?

Здравствуйте, какие зазоры клапанов на этом байке
what would be good compression found on these bikes.

Is that another one of those fisher Price My First Piston? Lol
were the cam shafts slightly hard to spin? and if so is that normal?
Sometimes they can be slightly hard to spin by hand when installed but will quickly loosen up right after the motor is started the first time. Its pretty normal
What do you usually charge for labor on a top end build say a crf 250r
around 325 labor
What do you charge to rebuild a 450 ??
a four strokes top end is about 325
@UpAllNight91 thanks you are a good mechanic

102 hours wow. I got 65 hours on my 22, im a B- ish rider do you think i can push to 75 80? Or should I just do it now

How many hours were on it?

Pretty impressive !
Where are you located ?

The company is called stuck nutz they’re trying to keep riding places open.
Stuck Nuts lol. Great name! Gonna do a little research. Thanks for the info
