Spark Plug - Yamaha RD250 Betriebsanleitung

Spark plug
Cleaning and gap adjustment: Clean the
electrodes and adjust the gap every 500 ~
1,000 miles (1,000 ~ 1,500 km).
Checking the condition of the spark
plug: If the spark plug is correct, the
insulator will be relatively clean and have
a tan color. If the plug is sooty, it should
be replaced with a hotter type. If white,
replace it with a colder type.
