Thanks for the time & effort making this video! ...Why didn’t you do a leak check of the valve seats after assembling the valves to ensure a good seal mate?
Not sure what you're asking. I could do a leak down test with the engine assembled but the rings aren't even bedded in yet. I'm pretty confident I have done enough to ensure a good seal.
@@2wheelworkshop before fitting the head to the motor, with the valves & springs fitted, fill the open ports with fuel or any thin liquid ( not water ) a see if the liquid leaks from between the valve & valve seats.
Tanks for your very interesting videos. I have a 1H1 650 XS to rebuild... I didn't understand how you made the blades to be on the same plan. I suppose you have to push the tool in the hole and only after that screwing the blades, no?
No worries mate. The blades are in a dovetail and can not be installed on different Plains. The only thing you can adjust is the cut diameter by moving them in and out.
It looks like the 650 XS's engine is not only good looking but a pleasure to work with. Everything looks oversized and rustic. You came across a very tired engine to have to redo the crankshaft but it's an impressive job, well done! @@2wheelworkshop
That’s great, and they are probably the best cutters of the bunch, however if you had to go buy that set of cutters today on the neway manufacturing site its about $1600 US for the motorcycle valve cutting kit. Certainly not encouraging for the DIY guy. Cheaper to go buy a new head or you could get your whole motor rebuilt for that.
I was using the inverse of sin to calculate the gap on the inside edge of the valve resulting from the 1 degree difference in angle of the seat and valve. Essentially calculating the length of the adjacent side of the resulting triangle.

Ooo rebranding!! Excellent! Love it! Well done brother
Thanks mate. Thought I should start putting some effort in. Took me the better part of a day just to design and draw the logo.
@@2wheelworkshop Good stuff, a new name! And quite a good number of subscribers. Well done
Thanks man. Getting there.
new logo looks pretty cool ;)
and thanks dad for the new tools to rebuild his engine for him
Thanks man. And thank you for the name idea.
no problem @@2wheelworkshop glad I could help.
Loving the new look mate.
Thanks man. Thought it was time I started putting a bit of effort into the look of the channel.

@@sirikulsomsuwan i might give that a try next time.

Thanks mate. It was a very tired engine but everything has been rebuilt now.

Very grateful to the old man. He has collected quite a few very good tools over the years.
I would like to purchase the valve cutter pls advice
I found this on the internet goodson.com/collections/neway-valve-seat-cutting-system
Sir how we know the correct angle of 60 degrees in cylinder head
You have to find the factory specifications. They are listed in the workshop manual. Then you have to use the correct angled cutter.
Sir i confused about you can use sin why we use sin
