Good work done. You could get even more good results if you follow some suggestions. First the weight of the newly made valves seem to be more massive, which may result in the bouncing at higher engine rpm. Next the valve face seat print must not be more than 1.5 mm. If it is less than 1.5 mm, the valve seat may overheat. If it is more wider, the valve can become sticky. The valve seat is always kept inside than the center line of the valve face. With the passage of time and usage, the valves tend to force inside the seat, and premature failure of valves can occur. Thank you again for your good work. Keep it going.
Congratulations friend, nice work. Here in Brazil we have the habit of leaving the back of the ADM valves very rough after helping against turbulence and improving the fuel air mixture.
I am really impressed with your tool collection. I have not done valve lapping in years, and back then it was done by hand. could you put a list of your equipment and flapper grit etc. This is fascinating.
complimenti per la professionalità, SUPER! posso chiederti che tipo di materiale hai usato per costruire le sedi valvole? Grazie. congratulations for the professionalism, SUPER! Can I ask what kind of material did you use to build the valve seats? Thank you.
Gracias por filmar Las reparaciones y reconstrucción que muy poca gente es capaz de hacer ni tiene capacidad ni mental ni técnica ni física ni mecánica para hacer lo que haces! Gracias
Very nice work ! When cutting the exhaust valve 45deg, how do you ensure that you have removed the right amount of material so that the valve lash in within the adjustable range ?
I always enjoy seeing you at work and the amazing tools and machines at work. I am not a machinist and have no knowledge of the craft, but I would like to ask a question: I notice that you do most of the machining processes without the use of a cutting fluid or coolant; why is that?
Hi Paul, I've watched quite a few of your videos on repairing the heads and cam bridges on the KTM's. Is this a service that you would quote for? I live in Scotland and I'm finding it very difficult to find a machine shop that is willing to take on the task of repairing my cylinder head off a 2018 SXF 250. The galling on the cam journals is not as bad as some of the ones that you have repaired. Kind regards Keith Thornburn
OLÁ. Muito interessante. Falta acabamento em algumas operações. Em outras falta conhecimento. O retirar e colocar a séde nova é Hilariante. Dependendo do sistema de fabricação da válvula é DESACONSELHAVEL reaproveitar uma válvula usada. ABRAÇOS... Roberto Udo Krapf
Great work...just material in and ex valves is not the same...usualy... You can make intake valves out of exhaust,but not a way around😬 But craftman skils you have are wery god
I repaired a KTM head to a friend some time ago. Exhaust valves were OK, and intake were destroyed. Strange, I thought. Then, I used a magnet and noted that intake valves were plain steel (magnetic) , an exhaust valves were some non magnetic steel, ( as it should). Not sure how manu tyme will last intake valves modified to exhaust valves due to the steel quality..
Hi Paul Is there a possibility to contact you by PM? Do you have an email or a website where I can write you? I have some questions about to rebuild seats and valve for a 1973 Honda CB350 twin. Thanks
@@PaulXchannel I have a 1973 Honda CB350 twin and I would like to change the valve seat by some one compatible with « modern » gasoline. How much it should cost and where to send it to you?
впускные клапаны на выпуск - плохая идея. неожиданное и странное решение. у них материал неподходящий. также материал сёдел и ширина рабочих фасок на них вызывают вопросы. я восхищён твоими другими работами, но этот случай - какая-то туфта.
Exactly. This video makes real machinist Cringe 😮.... Anything can be polished up to look nice. But heat and pressure will test the process. Scary for sure. But I'll say this, if he had some real equipment. He could do nice work...
with each of your videos I am amazed by the precision of your works and the ability you have to illustrate them. Well done👍🏻
Idk if I'm more amazed at the work or video editing...all around great job
the level of craftsmanship cannot be described in simple words
Very interesting work and nice to see that destroyed head brought back to life. Great effort for sure.
Mr. Paul thanks again for sharing your best experience

Thanks bro.
Paul you have reached out an outstanding and smart job, you deserve more fancy comments, and thanks.
I am watching with my mouth open. You are making your own valve seats. WOW. You truly are a master craftsman.
Such a nice job, this looks nearly brand new again!
The type of iron used in valve seats, good job brother 👍

How long do you think the valves will last?
Залипательное видео которое выдернуть меня из реальности на 25 минут
Gracias por filmar

Great repair and great tools!
Only a word.... art!
Great! Saw a drawer with spares of valve seats ..you did not use them on this one ?
Very nice work ! When cutting the exhaust valve 45deg, how do you ensure that you have removed the right amount of material so that the valve lash in within the adjustable range ?

You can get higher performance with coolant.

PoL are you renting a workshop? 🤔

Looks just like an RFS KTM cylinder head. Really close anyways. KTM must have bought the tech from Berg eh?

Why didn't you use the tig to get the seats out. You are a bit un Orthodox.where is your spirit level?
