SPARK PLUG INSPECTION
The spark plug is an important engine component and is
easy to inspect. The condition of the spark plug can
indicate the condition of the engine. The ideal color on
the white insulator around the center electrode is a
medium-to-light tan color for a scooter that is being
ridden normally. Do not attempt to diagnose any problems
yourself. Instead, take the scooter to a dealer. You should
periodically remove 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:
C7HSA(NGK), A7RTC(CHN)
Before installing the spark plug, measure
the electrode gap with a wire thickness
gauge, adjust the gap to specification if
necessary.
SPARK PLUG GAP:
0.6-0.7MM
When installing the plug, always
clean the gasket surface and use a
new gasket. Wipe off any grime
from the threads and tighten the
spark plug with your fingers first,
then later with a torque wrench.
