Valve Grind

1. Lubricate the valve seat using a fine-grained paste.
2. Lift the valve rhythmically from the seat with a commercially available valve grinding tool in order to distribute the paste.

3. Check the contact pattern on the valve head and in the cylinder head.
4. Clean the valves, valve guides and the cylinder head.

4. Ensure that there is no crater line burns on the valve cone.
5. The valve may be reground only two times. Do not grind the valve stem end.
6. Ensure that the angle at the valve face is 45 degrees.
7. Inspect the assembly height of the intake valves and exhaust valves.
