• 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.

work in a well-ventilated area.
