Man I had a hunch that you could fix the cylinder head no worries but that cylinder...nope...awesome work and I really enjoy watching your channel! Question, do you ever get asked to port cylinder heads? Just curious and thanks again! :)
Hey Paul, after a cup of relaxing coffee, you change your mind, didn't you ? Go ahead buddy, I love to watch how you get it done ! ....Actually I like your style !
My 2011 350 sxf is still working like new... My guess is that these very high revving engines absolutely need the recommended oil viscosity, which is 10w60, as per the owner manual. I have tried lighter oils and the engine was not running as good at all, more noise, overheating, hard to shift and such. I use top of the line synthetic only and change it every 5 or 6 hours.
The spinning table adds so much drama! I need to build one so when my customers want to see their failed parts I can que up the dramatic music and pull off the shop towel for added effect!!
Now that you did the cylinder head. And you have a new piston and new cylinder lower bottom liner are you showing the next video on the assembly, maybe alignment of the valve train and lobes. Maybe show us on the way the engine goes back together
That piston must have been really moving when the failure occurred . Total destruction !! In the animated movie called CARS one of the characters says "doc has three piston cups" then TowMater says "he did what in his cup" ?!! I'm going to have to say that's pretty dirty for a Disney cartoon , but it was pretty funny .
hola, tengo que cambiar las guias de valvulas a una husaberg fe450 2010 (similar a una ktm 450exc), para quitar y luego colocar las guias , ¿calentaste el aluminio?, ¿alguin tips para compartir? muchas gracias.-
Bore the old sleeve out, weld the block, bore again, install oversized sleeve, face. It can be done. If it wasn't for making youtube content, many would ask why.
Why bother? Swap in a 2-stroke and be done with it. Enjoy more power and less weight. Enjoy not having to do the valves. Save money by not needing to change the oil after every ride. Enjoy less noise. There is no real downside.
the head was not bad, same for the cylinder, you could just resleeve it but now days when you can get new heads etc for motor like this then whats the point putting so much labor unless its super rare and you cant get another.
Paul, in your opinion what do you attribute the vast majority of the damage to modern 4 stroke valve train damage. I see you repairing a lot of cam bearing surfaces and cams...
Bad lubrication of the head first with too low oil pressure on the aluminium bearing, that comes from a poorly designed oil pump and circuit. Mixing ball bearings and alu bearings is not the best of engineering, unless you make a dedicated high pressure circuit for the bearing. That is from difficult to impossible to correct as it's planned obsolescence. You fix it and it will break again. Poor design of the cooling circuit, a lot of bikes have problems of over-heating because the radiators are too small and often have no ventilators. It's possible to correct. And being cheapo on the surface treatment of some pieces. The easiest to correct, as good nitruration and eventually hard chroming can be done by specialized shops. Being high output engines the profile of the cams is very aggressive on the valves. You have to change the valves as regular maintenance. Maybe also the brand being cheap on the quality of the alloys of the valves.
clever stuff.....i liked the part about having coffee.....as i was watching it occurred to me that you could have easily made this into a children's instructional video along the basic lines of a sesame street thing with appropriate animations and music and comic relief........so much of child's entertainment is brain dead nickelodeon head garbage......you could create a whole new genre of children's entertainment for the 3 to 8 year old group with low key but accurate stories about how Mom's favorite car character personality was saved after it was damaged by the evil goblin who put a spell on the crankcase front seal which required an engine teardown to fix.....the whole story could be stretched out over 13 episodes as you treat the car engine like a foreign like gulliver's travels or alice in wonderland........anyway its a new and different project using the same material for somebody who can tell a story and is handy with animation
It was Maverick Viñales who drove this motorcycle 🤣
Jajajaja
Why? Vinales was not even able to destroy the m1 😂😂
🤣🤣🤣🤣yup!!
gp lovers only can understand this😆
Wahahahaha
Know The Mechanic or Know The Machinist . Nice work
Paul you are a master at work. Thanks for all your awesome videos. I give all a like 😁
Great job man,just like my old Kawasaki,broken connecting Rod,Hit the cylinder block,crankcase..Double trouble..
Man I had a hunch that you could fix the cylinder head no worries but that cylinder...nope...awesome work and I really enjoy watching your channel! Question, do you ever get asked to port cylinder heads? Just curious and thanks again! :)
If you can get that piston fixed and back in a running engine I’d be extremely impressed.
Are you okkay? Thats Bad imagination...
Hey Paul, after a cup of relaxing coffee, you change your mind, didn't you ? Go ahead buddy, I love to watch how you get it done ! ....Actually I like your style !
I must say you are really a genious & funny guy ! Paul
my ktm 505 needs your service paul haha
excellent work as always! much success
I had a 2011 350 SX. For this reason I'm back on a 2021 150 SX. Done with 4 strokes. To many expensive parts and takes to much time to repair

I also find myself searching the trashcan for parts😆
Amazing work, love from indonesia
kerja yg hebat .love from indonesia 👍

This video is made for effect only :)
@@PaulXchannel I need your contact. I have work for you
Nice engine!!!!

Would be nice to see an exhaust pipe restoration video aswell, good video!
Thanks.

Vídeo muito bom mesmo 👌 .eu só do Brasil . Rio de janeiro
Gotta show it running!
That's some hefty valve salad you got there.
Vera level sir
because a cup of coffee you change your mind so u grabbed back those from the trashcan.. brilliant..!! ☕ like I did that 😅
Where you get that die grinder set from ?? AMAZING work!!!
Lidl shop
Damn dude how you get this done ? Holy you smoke IT!
The question is what could make that kind of blowup?
I wonder how it happened!
🤔
Same here. I'm guessing timing chain failure. And it was obviously revving pretty high when it blew.
this cylinder is fixeble, if you want is perfect safe after fix
Duuuude.... why in the world would u make short videos?? We need long stuff like if were air
I don't want to repeat.
I already have a similar video.

Racing 4 strokes. It's not IF they blow up, but WHEN, and how MUCH.
I knew the cylinder was scrap, but I had a feeling you'd try to save the head.
This Is why the 2stroke Is coming back
@@stratosphorus Word. None from the fools at Honda, and no 125s or 250s from Kawasaki or Suzuki sadly. Looking forward to the KX112 though...

Safe to say piston and valves are toast!
Hello, I have a Ktm sxf 350 cylinder head that it’s damaged, how can I contact you for help?
Have you kawasaki klx250 cylinder head repair video ?

Ok, just drink a coffe for brillian skill... 😅😅
Nice bro
Number one 💪
The whole process can't be done without that cup of coffee 😂😂😂🤣 i mean the spoon..........tools

if it was a 2 stroke, new piston and cylinder rehoning and she'd be running like brand new again
Nah bruvv if piston explodes you prolly gonna need new conrod
heck yeah
Perfection !!!
Please tell me that that thing was hit by RPG.
Can I send you my Dr650 head? I have new seats and valves.
Someone wasn't checking their valve clearances regularly !
thats what we call BIG SEND hahaha
How hours this motor?
Where are you located? you do any “costumer repair work”?
I do not provide this service publicly.
Waduh hancur kayak gitu larinya gimana tu motornya ga bisa bayangin 👍👍
Bruh were can i find this type of engine. Its a DOHC egine type thing right? I heard they hella fast
Nice👍👍👍
Paul, in your opinion what do you attribute the vast majority of the damage to modern 4 stroke valve train damage. I see you repairing a lot of cam bearing surfaces and cams...
In my opinion - late valves replacement.
They simply get tired and fall into the combustion chamber.

Mixing ball bearings and alu bearings is not the best of engineering, unless you make a dedicated high pressure circuit for the bearing.

OK 👍
pozdravljeni, zelim popraviti

OOOOOOO... that was painful to watch...
It can be saved I think
wow and the piston too? xD
unos crack
Mission impossible..😬

The story tell nothing about the cylinder!!! Was it changed or repaired?
3:33
I have ovality in my fz750 main brg bores ( shells removed) what is your opinion on how to remedy this please thank u ( four cylinder five main brgs)
See this video
czcams.com/video/xHgg2pSGRVU/video.html
All I gotta say is my Hondas never done that.
Top.
Was it a failed 'oil pump' gear?
I don't know
Wowww.
Стал 2тактным цилиндр🙂
No sanks!
Valve failure at high rpm?
I bet it was failure of vertex piston ...
It's called buy new parts
I would just give up on bikes if that happened
😬💪💪💪
Ouch...
hello I would like to ask if you would like to repair my Yamaha wr 400 head
Thanks for the trust but I'm very busy.
@@PaulXchannel I'm in no rush, I'll wait
Holy shit
Just little bit cyanokrilate and will be like new one
Super glue....
nightmare
Horror 😱
🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥😁👍

What the hell
The cylinder is f$#-t
And the rest is fine????
@@patverum9051 in the right hands can be rebuild.
