Świetny pokaz naprawy głowicy. Szczegółowo, nie ukrywając szczegółów. Ogromnie przydatny. Przekazano wiedzę, której trudno znaleźć w książkach. Ten film to rodzynek !!! Nie spotkałem takich nigdy. Podziwiam, pozdrawiam i dziękuję.
Great video no worthless chit chat just a good job being done in an expert manner . Great tools and equipment .
man.., I love this kind of stuff. that was awesome.., instead of buying a new head, you totally fixed the old one like a Road Warrior.
you have a tool for everything. that's heaven for me.
A great demonstration clip with profound wisdom that really pays off. Thanks Paul !
The precision tool for measuring valve seat counter bore diameters is excellent. Never realized such a tool existed and figured you'd just use verniers.
Great demo , cool Tools and a lotta Work ! thanks I felt like I just did a day in the shop:)
All those amazing, high end, expensive, precision tools... 😍
Wish we had someone as talented as you and your machines around here. I need valves cut right now lol
Attention to detail , same principal as a custom Chevy cylinder head . Nice job .

Great work as usual! 👍
very relaxing to watch, informative too
Profesionální práce, nádhera.
Showed a great work with the hardest things
great technique, and great tools công😄👍
Nice video, thank you. Your tools make me envious. I have a flow bench and you were in a great place to improve the flow simply by boring the valve insert seat to .9 diamanté's of the valve and then do a back cut on the valve seat. That would give you a bigger flow gain than porting the head.
cheers and nice tools.
Do you mean a thinner valve seat? (Smaller inside diameter?) and then adding chamfer on backside of seat towards valve guide?
@@muushkin Most people when porting a 4 stroke head focus on the port and narrowing the boss around the guide. but the biggest flow improvement comes from the valve seat area. Measure the valve OD diameter then bore in past the insert about 5mm exactly 0.9 of that valve diameter OD and blend into the port with grinder. Then cut the 45 degree seats and use the 30 deg top cut to position the head valve seat where you want on the valve. Then a very important step is to back cut or grind the inlet valve to 30 deg from the 45 deg seat edge towards the stem so that the valve ends up with 3 angles and the inlet seat seat ends up with 3 angles. Clear as mud I bet😁. Flows like a stream train 👍
@@markjohnson6130 I go .9 on the intake seat and .85 on the exhaust.
@@mikerieck306 Small world Mike lol. I linked into your dyno Vid, impressive stuff, it sounds really quick in the higher RPM, kept the dyno operator reflexes on the ball.
Beautiful work.

Very precise repair with the use of perfect tools. Another congratulations 👌.
Thank you 😀.
Great videos 👍
Nice video, a pleasure to watch.
These are tools of my dreams!! 🤤
I have done hundreds n hundreds of these trx heads guides also shift get loose
A easier way of removing seat is to shrink it with weld basically falls out i use to use kerzan valve inserts kz3819 they are extra thinker than the average seat insert the valve height out the back is 37-37.5mm from spring bass to valve tip i also make oversized guides
👍
Excellent job and great equipment just saying
un buen trabajo muy profesional saludos
Nice presentation thanks 🙏 👍
I could watch this chit all day! Give me more please.

Bel lavoro ,, good work
Хорошо бы перед таким серьезным ремонтом заменить направляющую втулку клапана, что бы базирование пилоты было более точным, и полностью восстановить ресурс сопряженных пар трения.
You have some mad skills in the machine shop!!! Very nice work and can't wait to see some more! :)
Beautiful.
back in day i did in my mopeds-moto cross bikes & cars, in old 80''s hand tool a bigger valve seat.
Good job!!👍🙂
Genuine work very nice 👍
Great work
Show,só ferramentas top
Finally someone not using center drill in the lathe, because they are not putting in a center.
good tools and work
Great video 👍
very nice. precision is kinda my Jamz
Nice video paul👍. Just suggestion for next video how to change big valve for cylinder head. Thx
Muy chingon trabajo
I just can say.. wow... 😍
I use PC air duster to freeze parts. Costs less than half of those "freeze sprays" and does the same thing. Just hold the can upside down so the liquid comes out.
Your video was epic 👍
love that machine
Waww amazing very very précision work very nice thanks 😊
Sir, you are Best
Wow, amazing!!
Goodjob & good tool
Good and clean job.Try to pour some alcohol when you cutting the seat pocket at the head.you will have better wall surfaces.
You are awesome!
good job brother 👍
perfect job
Very ASMR and funny edit. You might want to tag that in the vid to get more views. 👌
How much this item cost brother?
Good replacement and precision tools and carefull measurement but i see some sharp edges above the seats carbon deposit might build up there
precision 👌joss
Very very veryyyyy good job 💪👌✌
OLÁ. 26/12/23. Completando... a ferramenta utilizada é ÓTIMA mas faltou o acabamento final que indica a área de vedação que se tiver invertida poderá em muitos motores provocar a "flutuação de válvulas" que as vezes é confundida por "corte devido a rotação excessiva. ABRAÇOS...Roberto Udo Krapf
Very very nice, thanks,
Super vidéo avec quel matière les sièges de soupapes sont refaits ?
Could you please indicate at wich temperature you need to heat the head and what is the (very impressive) refrigerant spray ?
What a patience consuming process
