B. Engine Lubrication
You must change the oil in the crankcase after the first 5 hours of operating your new
engine (see Fig. 7) and after 10 hours of use thereafter. This will insure proper lubrication of
internal parts and prevent costly repairs due to excessive wear.
a. Remove drain plug located on the right rear side
of engine. Tip kart backwards slightly by blocking the
front tires and drain oil into suitable container.
b. Remove and clean oil screen.
c. Replace drain plug and tighten securely.
Place kart in a level position.
d. Refill crankcase (approximately 1-1/4 quarts)
to top of filler neck with SAE 10W40 oil.
e. Check oil level before each use of kart or after
each 10 hours of operation. Add oil to bring up to
proper level. Do not mix various grades of oil.
C. Spark Plug
a. Remove the spark plug and inspect it each time you
change the oil. (Use a spark plug wrench.) Keep the
electrodes clean and free of carbon. The presence of
carbon or excess oil will greatly reduce proper engine
performance. If possible, check the spark plug gap
(area between electrodes) using a wire feeler gauge.
This specification is 0.6~0.7mm.
b. Before installing the spark plug, coat threads lightly
with graphite grease, if possible, to ensure easy removal
in the future.
c. It is advisable to replace the spark plug at least once
Used oil must be disposed of at a proper collection center
