(6) INTAKE AND EXHAUST VALVES
Take the following points into account when
mounting the intake and exhaust valves on the
cylinder head.
NOTE1: Replace the valve with a new one if
it shows signs of wear. (Refer to the
"STANDARD REPAIR TABLES" on
page 71 and 72.)
NOTE2: Carefully scrape off any carbon deposits
on the combustion chamber. Apply oil to
the valve stems before mounting the intake
and exhaust valves. Insert the valves in
the cylinder head and place it on a level
workbench. Next, mount the valve springs,
the spring retainers and collet valves.
(Mount the stem seal on the intake valve
guide.)
