Do not attempt to diagnose such problems
yourself. Instead, take the ATV to a Yamaha
dealer. 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.
