SERVICE INFORMATION
GENERAL INSTRUCTIONS
• Do not bend or twist control cables. Damaged control cables will not operate smoothly.
• When disassembling fuel system parts, note the locations of O-rings. Replace them with new
ones during assembly.
• Before float chamber disassembly, loosen the drain screw to drain the residual gasoline into a
clean container.
• After the carburetor is removed, plug the intake manifold side with a clean towel to prevent
foreign matters from entering.
• Remove the vacuum diaphragm before cleaning the carburetor air and fuel passages with
compressed air to avoid damaging the vacuum diaphragm.
• When the motorcycle is not used for over one month, drain the residual gasoline from the float
chamber to avoid erratic idling and clogged slow jet due to deteriorated fuel.
• The pilot screw is factory pre-set and no adjustment is necessary. During carburetor
disassembly, note the number of turns of the pilot screw and use as a reference when reinstalling
it.
• A tachometer must be used when adjusting the engine speed.
• Turn the pilot screw in or out slowly to obtain the highest engine speed.
