SERVICE INFORMATION
GENERAL INSTRUCTIONS
· Gasoline is very dangerous. When working with gasoline, keep sparks and flames away from
the working area.
· Gasoline is extremely flammable and is explosive under certain conditions. Be sure to work in
a well-ventilated area.
· 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 reassembly.
· 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 shop towel to
prevent foreign matters from entering.
· The carburetor air jets and fuel jets must be cleaned with compressed air.
· 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.
