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 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.
