-- Insert the valve into guide. The valve stem end must be flush with the guide. Due to differences in valve stem diameter, only use intake valves in intake valve guides, and exhaust valves in exhaust valve guides.

-- Determine the tilting clearance.

Wear limit: 0.5 mm.

-- If the wear limit is exceeded, measure using new valves.

-- Replace the cylinder head if the wear limit is still exceeded.

NOTE:

The valve guides cannot be replaced.
