valve stem and the valve guide.

Install the valve into the cylinder head
Turn the valve till valve face and the valve seat are

For good effective, knock the valve seat lightly while
turning the valve back and forth with two hands.
Smear fine grinding agent on valve face, and then
repeat the above steps.
After grinding each time, wipe the grinding agent on
