SERVICE INSTRUCTIONS
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.
E
c. Replace the drain plug and tighten securely. Place the kart in a
level position.
d. Refill the crankcase (approximately 11/4 pint) 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. Before installing the spark plug coat the threads lightly with graphite
grease if possible, 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.
