8-31 Periodic Maintenance and Adjustment
Instead, take the ATV to a dealer. You should
periodically re-move and inspect the spark
plug because heat and deposits will cause
the spark plug to slowly break down and
erode. If electrode erosion becomes
excessive, or if carbon and other deposits
are excessive, you should replace the spark
plug with the specified plug.
Specified spark plug:
DR8EA (NGK)
Installation
1. Measure the electrode gap with a wire
thickness gauge and, if necessary, adjust
the gap to specification.
Spark plug gap:
0.023-0.027 in (0.6 - 0.7 mm)
2. Clean the gasket surface. Wipe off any
grime from the threads.
3. Install the spark plug and tighten it to the
specified torque.
a. Spark plug gap
Tightening torque:
Spark plug:
17.5 Nm (1.75m·kgf, 12.7ft·lbf)
NOTE:
If a torque wrench is not available when you
are installing a spark plug, a good estimate of
the correct torque is 1/4 to 1/2 turn past
