Just did my top end watching you step by step. Thanks heaps
Heck yes, glad you enjoyed it, thanks for watching!
Rewatched this 1m times thanks so much for your detail. Only thing I’m concerned with it the bolts on the cam caps, you breezed over them pretty quickly
7.2 foot pounds in a criss cross pattern and you can’t go wrong. Not rocket science, just engines 😃 easy to make ver complicate things and get worried.
I am going to buy an old Yamaha and let you rebuild it for me. Awesome job. Thanks for sharing.
Haha you betcha! Thanks for watching!
One pause n Yeah away from a hate comment lol 😆
Nice job love the attention to detail. Clean build n bike👊✌️
Please bro lol thanks for watching man, and I know you’ll be back for more, so get over it lol all the love brother!
@@DanMX2112 Agreed 🤝
Would be a lot better without the music
Just finishing 2 YZ250F and Splitting the case on a WR450F. The ring choice (factory OEM) on the 450 is obvious due to thickness. but doesn't seem to match the side profile of the manual. I had to put it aside for the evening. I'll re-evaluate in the AM. I think I've met my match for being anal in the cleanliness department. I'm picky, your obsessed👍👍
I can’t work unless my life and bench are organized haha glad to hear someone out there care as much as I do. Let me know what you figure out, curious on the issue. Thanks man, and good luck!
When you are talking about clocking the rings to the correct degree, where is 0 degrees at on the piston? Just needing to know where to start!!😂
In the manual it will show you. I use the exhaust side of piston, arrow side, as 0.
@@DanMX2112 yup, found the image in the manual. It was harder to get the cam chain on than I was anticipating. I need to replace my fly wheel and stator also!😬 waiting for those to get here.
All new when you go back together. Gonna be awesome!!
If I do 180 from each other away from the wrist pin (facing exhaust and intake valves) will it no start condition?
You will bend valves and have tons of issues.
I followed the video exactly step my step and I still have no compression, any suggestions? I’m thinking to maybe go over the rings and cams?
My 07 has a washer behind that crank bolt , yours didn’t ???
My 06 did not, that why it has that flange nut. May have changed in 07.
@@DanMX2112 copy that 👌🏽
what was that sound at 56:13 my bike does that sometimes as well
Not sure, I just listened and it didn’t sound like anything weird. Maybe just the kickstarter.
Awesome video, fixing to do first top end rebuild on an 07. Where do you get that print off for organizing the valve buckets with all of their measurements?
Dm me on Instagram and I’ll
Email them to you!
@@DanMX2112 awesome, just sent you a dm on IG. Thank you!
hey, so my bike just keeps backfiring. I did what you did. what should I check?
It’s a lean jetting issue, your pilot jet is to lean cause it to backfire of the throttle. Go a size and play with it.
would u have any tips how to unlock or un seize my wr450f 2017?
You’re gonna have to split the cases. Sucky situation man. How many hours are on it? And where are you located?
@@DanMX2112 i ended up not getting the bike but was wondering would a wr450 2012 frame fit on a wr450 2003 engine and that?
Have u ever ran into a bent exhaust valve & dropped exhaust on cylinder head .. the valve dropped and stuck in piston
Does the cam caps HAVE to be removed when timing? I’ve been keeping them on for the 1-3 tooth adjustment and still not starting. Tried everything
It’s very hard to do, but I think can be done
@@DanMX2112turns out the rings where over heated and bore was oval. All my valves needed to be regapped for spec and piston had colour in it
In the end I bought the $900 Athena 95mm kit with bore and slapped it on
Nice, bike run like it should now I’m assuming? Glad you ironed it out.
Do the cam shaft go on the notch there or not? About to finish top end pls lmk Asap
The cam shafts will self center using the keepers on the cam caps.
Is this the same procedure for a 2005 yz450f
Nearly identical!
Is t there some sort of method you need to do for the oil to reach the top of the motor I was briefly told I need to do some something in order for that to happen . Great build my motor is coming out the shop tomorrow and I can’t wait I’ll send photos on ig when the bike is put back together
Great question, so on a full rebuild I do the following. Add oil, remove filter cover and oil filter. While holding the kill switch, and having fuel off, I roll the bike over using the kickstarter slowly till oil start to come up into the filter housing. Install the filter, filter cover. Again roll the bike over slowly for about 10 rotations and the go ahead and fire up. This will bring oil up through the filter housing and should get up close near the cam journals, if not oil them fully. Now, your engine builder should have used a assembly lube, or motor oil to assemble the components on the head. Otherwise, it will be a dry start or semi dry start if you don’t prime the oil pump. Hope this helps you out.
Bom dia, amigo eu tenho uma wr 2007 250 ela tá com pouca fouga no vira brequim vc tem passo a passo dela ?
Just wanted to point out ur using an extension so the torque won’t be 100% correct
All good! Not much you can torque on these bikes without one. Thanks for watching, hope the video helped out!
Extension won't make a difference with a torque wrench, only with an impact. There is constant force on the extension with the torque wrench so it transfer like normal.
Is the rebuild similar to 2015 yz450f?
Everything is nearly the same, but a few differences.
@@DanMX2112 What differences?
@elkku2934 exhaust and intake direction, differences in fuel injection, 4 valve head, couple minor things.
@@DanMX2112 oh yeah, I know these. Do you know if the flywheel puller is still 24x 1.5 on 2015 yz450?
@@elkku2934 not positive on that, but i would assume that yamaha hasn't changed that thread pitch.
hey Daniel. I have exactly such a motorcycle and I have a problem, can I consult you privately?
Sure Dm me on Instagram!
hey Daniel. I have a 2009 yz450f and I have a problem with the inner shaft of the water pump, can it be removed without disassembling the engine into two parts?
Yes, you’ll have to remove the inner clutch cover, it really is not as bad as it seems. Look up a few videos online and I bet you find something showing you so details. Very easy fix, but takes a bit of time and cleanup.
Got it, I can't find a movie that will show me this. Then you have to open the engine block
Nice very clean your attention to detail is awesome 👌
🤝✅✌👍💯
🙏 😃 🔧 🎥 🤣 thanks bro!
good video tho trash music
lol good comment, tho a waste of time. Thanks man!
@DanMX2112 for real tho very helpful. Just picked up a wr450 that someone hacked together. so it's good to have a detailed build to watch!
