Cylinder Head Assemble - Suzuki XL7 2007 Service Manual

1D-186 Engine Mechanical:
6. If the maximum height specification is exceeded, a
new valve should be installed and the valve stem
height re-measured.
CAUTION
!
DO NOT grind the valve stem tip. The tip of
the valve is hardened and grinding the tip will
eliminate the hardened surface causing
premature wear and possible engine damage.
CAUTION
!
DO NOT use shims in order to adjust valve
stem height. The use of shims will cause the
valve spring to bottom out before the
camshaft lobe is at peak lift and engine
damage could result.
7. If the valve stem height still exceeds the maximum
height specification, the cylinder head must be
replaced.
