 SERVICE INFORMATION
 GENERAL INSTRUCTIONS
 · The cylinder head can be serviced with the engine installed in the frame. Coolant in the radiator
   and water jacket must be drained first.
 · When assembling, apply molybdenum disulfide grease or engine oil to the valve guide movable
   parts and valve arm sliding surfaces for initial lubrication.
 · The valve rocker arms are lubricated by engine oil through the cylinder head engine oil passages.
   Clean and unclog the oil passages before assembling the cylinder head.
 · After disassembly, clean the removed parts and dry them with compressed air before inspection.
 · After removal, mark and arrange the removed parts in order. When assembling, install them in
   the reverse order of removal.
