7.1 Spark plug inspection
The spark plug is important engine components, which should be
checked periodically.
1. Remove the cap (1), and use the tool (3) remove the spark plug cap
(2), and Insert the tool (5) through the hole from the outside of the
cover.
2. Insert the handlebar (4) into the tool (5) and turn it counterclockwise to
remove the spark plug.
3. Check for discoloration and remove the carbon. The porcelain insulator
around the center electrode of spark plug should be a medium-to-light
tan color.
4. Check the spark plug type and gap.
Standard Spark Plug:
TORCH-A5RTC/E6TC/E6RTC
Spark Plug Gap: 0.6-0.7mm (0.024-0.028in)
TIP: The spark plug gap should be measured with a wire thickness
gauge and, If necessary, adjusted to specification.
5. Install the spark plug.
Spark Plug Torque: 12.5 N*m (1.25 kgf*m, 9 lbf*ft)
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.
6. Install the spark plug cap and spark plug cover.
