 SERVICE INFORMATION
 GENERAL INSTRUCTIONS
 · During crankcase separation, do not separate the crankcase halves with an iron hammer to avoid
   crankcase deformation or damage.
 · After separation, be careful not to damage the right and left crankcase mating surfaces to avoid
   oil leakage.
 · Replace the gasket with a new one during reassembly of the crankcase halves.
 · After transmission system disassembly, make sure that the gear shifting operation is normal
   before reassembly of the remaining parts.
 · Apply engine oil to the transmission system and crankshaft before reassembly.
