Valves
07 Dec 2017 16:12 - 07 Dec 2017 16:13
I have a 750 engine running fine, but was leaking oil from the head gasket and when I open up the engine I found the cylinders "walls" to not be in perfect condition, please see here:
kzrider.com/forum/2-engine/607482-cylinder-wall-condition
I have some question about the valves, what shall I do to get the valve in good condition?
www.partzilla.com/catalog/kawasaki/motor...alves-81-83-h2-h3-h4
When it comes to the valve, what part should I replace?
The valve it self, or can I just clean and re use?
Oil seal?
Valve guide?
more to replace ?
I was thinking to deliver the top into workshop, but what shall I advise them to-do?

Thank you I`m new to these game, I want the engine to get in good condition and work for many years.

Cool

So your point I only need to grinding the valves?
I believed it was normal also to grinding the valve seat also?
Work:
1. grinding valve
2. grinding valve seat
Parts:
1. Will you advise to replace the valves with new one? any point?
2. Oil seal?
3. more ?
Have I control now ?

Don't take it to just any shop. They can trash the head.

I understand it`s a shop with good references.
But what part do I need ?

Only the oil seal?

Oil seal only at first, and have the shop grind the valves and then check the seats through careful inspection and lapping to check the seat contact area. If the seat shows a good contact then you don't need to grind them.
