SPARK PLUG
« Remove the spark plug.
Carbon deposit
Spark plug gap ;
09900-20803 : Thickness gauge
Spark plug gap
Standard : 0,7-0.8 mm
Electrode's condition
" Check to see a worn or burnt condition of the electrode. If it
is extremely worn or burnt, replace the plug. Also replace the
"plug if it has @ broken insulator, damaged thread, etc.
Heat range
NGK or DENSO should be used as the standard. However,
the heat range of the spark plug should be selected to meet
the requirements of speed, actual load, fuel and etc. Proper
heat range would be indicated if insulator was LIGHT BROWN
in color. If it is blacked white, it should be replaced by a cold
type plug NGK CR9E or DENSO U27ESR-N and if blacked by
carbon, by a hot type plug NGK CR7E or DENSO U22ESR-N.
