Installing valves
Fig. 4
Apply oil to valve stern and insert valves into valve
guides.
Note:
Minor damage to the valve seat can be
eliminated by lapping using valve lapping
paste. New valves must always be lapped
until an even valve seat has been
achieved. Machine valve seat insert if nec-
essary.
Turn cylinder head over and insert valve spring
washers. Screw off valve assembly lever.
