Inspection
The spark plug is an important engine compo-
nent and is easy to inspect. The condition of the
spark plug can indicate the condition of the en-
gine.
The ideal color of the porcelain insulator
around the center electrode is a medium-to-
light tan for a vehicle that is being ridden nor-
mally. You should periodically remove and in-
spect the spark plug because heat and deposits
will cause the spark plug to slowly break down
and erode. If electrode erosion becomes exces-
sive, or if carbon and other deposits are exces-
sive, you should replace the spark plug with the
specified plug. Measure the spark plug gap with
a wire thick- ness gauge and, if necessary, ad-
just the gap to specification.
