I have been working on motocross engines for almost 10 years, and I just bought my first CNC mill and will be getting 2 more manual mills and a lathe this week to make MX parts. Watching these videos is like heaven on earth to me.
I wish you a lot of success.
@@PaulXchannel could you make a valve bucket sleeve for a 2006 kx250f? My head is damaged and I need one
The slow no from drilling the sleeve was so nice! Lol
This Old Tony has got some serious competition here!
there is a lot of professionalism in these videos. compliments
Thanks
Втулки ремонтные изготавливаются из латуни и впрессоваваются нагорячую(корпус нагревается в кипящем нигроле(200-250С.°) и впрессовавается(впрессовавается всмысле нагорячую само входит и при охлаждение корпуса обжимается),втулка прямая без бортика(без расширения),также нагорячую прессуются подшипники и даже иногда коленвалы и сразу закалка маслом через сутки будет видно.
Приятно читать Русскую речь под забугорным видео)
Сука,
там станков и инструмента на лям.😨
А он ремонтирует какой то мопед
You have my dream job,i currently work something else so one day I can build a garage like yours,keep it up
👍
Belíssimo trabalho, muito rico em detalhes. Uma verdadeira aula. 👏👏 Ansioso para assistir a parte 2.
Nice work, looks better than new .
In my experience, the CRF seems to be prone to top end issues , at best they like the valves to be set just right ,or they can be a dog to start . I also have KTM SX ,no problems there,and it out performs the CRF in every test .
Thanks for a very professional video.

Stronger than new! Excellent job!
Excellent work a pleasure to watch you repair things...if i ever damage anything like that you'll be getting it for repair....
Thanks
Sos maravilloso!! Yo vivo en un país que para tener tus herramientas hay que ser multimillonario , una lastima, te admiro!
Repair videos are the best videoooss!!
The head must be made of unobtainium! Or your labor is free. Time to buy a new head along with the rest of the bad parts. But your video is worth watching. Thanks.
Very, very nice Job👍👍 Respect💪
Wow, amazing. Never seen this done before. Thanks for sharing.
Hi.very good
Thanks
Now that my friends is some serious machine work amazing!!!
Should have washed and cleaned the head (carbon deposit) and honed guide to valve stem before installing new valve seals.
But you have talent and tools for the talent! Great video!
Thanks.
You need to watch the video to the end.
Continued in the second part.

It is impossible to not watch The best REGARDS Ziggy Canada najlepszego zycze
That is some really nice work.
Thanks
I loved that machining part but not so much that welding part, porosity all over the weld. I know it gets a sleeve but this part could've been done better in my opinion.
Great tools and that boring attachment for your mill looks awesome!
Thank you for watching.
The weld did not contain any bubbles.
The weld was good.
@@PaulXchannel you make great videos, I like the format and the music was great! 👍
And the porosity can be seen at 11:39, 11:41 and 11:45. That particular cylinder head was probably okay, however if I would’ve finish mu job like that my boss would fire me 😂😂
Ok
Where you do this great job? I'm from Poland and i have some cylinder head to repair.
That’s awesome and nice work 👍
Thanks

I love ur channel, I hope I can afford tools like yours someday, new subscriber here ❤️
Some doubt that the sleeve glued with Loctite will stay in place for a long time.
Sto toccandomi le balle che non mi succeda. ...ma nel caso malaugarato...questo lavoro cosa costerebbe farlo e se lo fai nel mondo? Sei un artista 💪
Super nice but ? Mill quill on angle is a pain. Why do you not prefer head mounted to sine plate. Locate pin with quill at perpendicular to table top adjust sine plate perpendicular to pin? Curious Thanks
Ok
Subscribed!👍
Sir, the video is excellent! You can become a professor in MIT! Thank you🙏
The only bit that got me worried was the filing down of where the bush is in the camshaft bearing journal... all good in the end though 👍🏻
Ok

How much do you charge for this service?
Very very nice! Keep up the great work👌👍👍
Thanks
How come only one valve get impact? Is it due to exceeding max. valve lift?
I wish these legend right here have Clones

SUPER MASTER 100%
Thanks
Sangarr broo👍👍
Very cool. Subbed 😎
Thanks for watching
Excelente trabajo
YEA there is going to be a lot of indicator movement on a slip fit pin locating the valve guide. Why cant you get a descent finish on aluminum. Ever heard of a thermal fit for the sleeve. You can BS the average guy but to a tool and die maker you have a lot to learn.
Ok
Muito bom excelente trabalho 🇧🇷
can you show detail about stator crf250r... some people can make the stator to charge the battery .. and till now i never seen on anywhere people do about that crf250r stator 😁😁
Man I need these tools this guy has to modify some whizzer bike engines I have
¡¡Qué calidad!!
mierzyłeś na zaciśniętym hamulcu w mikrometrze:D
Nice work, but you forgot to ream the new valve guide after pressing it in.
I did not forget.
It was not necessary.
Man I love how perfect you got that bucket to fit. It’s almost like you’ve done this once before? Lol
4 stroke. How many? 2 hp?
What an art
👍👍
I think this aluminium head will expand with a heat, is this not too tight clearance between the bush and the valve cup? It look like it's less than 0.01 in your video. Thank you.
It's my standard procedure that works.
Beautiful👏👏👏👏👏👏👏👏👏👏👏👏😎😎😎
Thanks
Wasnt there a giant crack at the opposite side of the weld?

THE BEST
Thanks

Beautifull job really, what kind of aluminum did you use? Many thanks for the videi
Thanks for watching.
AlMgSi0.5
Is a new head not cheaper than the shop time?
Tenho um cabeçote dessepara recuperar .eu não acho ninguém para fazer esse serviço.
ream the guide to size, check the valve seat is still centered with the new guide
