Take care not to damage the fuel hoses when raising the
fuel tank.
The plug gap is adjusted to 0.6 - 0.7 mm (0.02 - 0.03 in)
The gap is correctly adjusted by using a thickness gauge. When
carbon is deposited

the spark plug, remove the carbon with
a
s~ark
plug cleaning machine or by carefully using a tool with
a pointed end. If the electrodes are extremely worn or burnt,
replace the plug. Also replace the plug if it has a broken
insulator, damaged thread, etc.
NGK JR9B as listed in the table should be used as the standard
plug. However, the heat range of the plug should be selected
to meet the requirements of speed, actual load, fuel, etc. If the
plugs need be replaced, it is recommended that ones having
a heat range closest to the standard plug in the table be
selected. Remove the plugs and inspect the insulators. Proper
heat range would be indicated if all insulators were light brown
in color. If they are baked white, they should be replaced by
a cold type NGK JR 1OB

CAUTION:
Confirm the thread size and reach
when replacing the plug. If the reach
is too short, carbon will be deposited
on the screw portion of the plug hole
and engine damage may result.
NOTE:
uR"
type spark plug is installed for
some specifications. "R" type spark
plug has a resister located at the center
electrode to prevent radio noise.
