To check the spark plug

 

1. Check that the porcelain insulator around the

center electrode of the spark plug is a medi-
um-to-light tan (the ideal color when the ATV
is ridden normally).

NOTE:

 

If the spark plug shows a distinctly different color,
the engine could be operating improperly. Do not
attempt to diagnose such problems yourself. In-

 

stead, have a Yamaha dealer check the ATV.

2. Check the spark plug for electrode erosion

and excessive carbon or other deposits, and

replace it if necessary.

 

To install the spark plug

 

1. Measure the spark plug gap with a wire thick-

ness gauge and, if necessary, adjust the gap
to specification.

 

1.  Spark plug wrench

Specified spark plug:

NGK/CR7HSA

Spark plug gap:

0.6–0.7 mm (0.024–0.028 in)

 

1.  Spark plug gap
