B. Engine Lubrication
You must change the oil in the crankcase after the first 5 hours of operating (See Fig.7)
and after every 10 hours of use thereafter. This will insure proper lubrication of the
internal parts and prevent costly repairs due to excessive wear
a. Remove the drain plug located on the right rear side of
the engine. Tip the kart backwards slightly by blocking
up the front end and drain the oil into suitable
container.
b. Remove and clean the oil filter.
c. Replace the drain plug and tighten securely. Place the
kart in a level position.
d. Refill the crankcase (approximately 0.9qt) to the
top of the filler neck with SAE 10W40 oil.
e. Check the oil level before each use of the kart or
after each 10 hours of operation. Add oil when
necessary to keep the level between the bottom of the
dipstick and the "0" mark. 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). The
electrodes should be kept clean and free of carbon.
The presence of carbon or excess oil will greatly
reduce 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. If available, before installing the spark plug coat the
threads lightly with graphite grease to ensure easy
removal next time the spark plug needs inspection.
c. It is advisable to replace the spark plug at least once a
year to ensure easy starting and good engine
performance
