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 vehi-
cle is ridden normally).
TIPIf 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 vehicle. 2. Check the spark plug for electrode erosionand excessive carbon or other deposits, and
replace it if necessary.

grime from the spark plug threads.
2. Install the spark plug with the spark plug wrench, and then tighten it to the specified
