8. PERIODIC MAINTENANCE:
Spark plug inspection
TIP:
If a torque wrench is not available when installing a spark plug; a good estimate of
the correct torque is 1/4-1/2 turn past finger tight. However, the spark plug should
be tightened to the specified torque as soon as possible.

The spark plug is an important
engine component which
should be checked periodically.
1. Remove the cap ① and spark
plug cap ②.
2 . Insert the handlebar ③ into
the tool ④ and turn it
counterclockwise to remove the
spark plug.
3. Check for discoloration and
remove any carbon deposits.
The porcelain insulator around
the center electrode of the spark
plug should be a medium to
light tan color.
4. Check the spark plug type
and gap.
Standard Spark Plug:
E6TC E6RTC
BP6HS / BPR6HS (NGK)
L87YC /R L87YC (CHAMPION)
W16FP / W16FPR (DENSO)
W6BC / WR6BC (BOSCH)
If needing EMC Certification,
engine must use E6RTC spark
plug.
Spark Plug Gap:
0,6-0,7mm
TIP:
The spark plug gap should be
measured with a wire thickness
gauge and, if necessary, adjust.
5. Install the spark plug.
Spark Plug Torque: 20.0 Nm.
6. Install the spark plug cap and
spark plug cover.
