Spark Plug - Baja motorsports DOODLE BUG Manual Del Operador

WARNING:
Before inspecting, cleaning, or servicing the mini bike,
shut off engine, wait for all moving parts to stop, ensure
engine switch is in OFF position and disconnect the spark
plug wire. Failure to follow these instructions can result in
serious personal injury or property damage.

SPARK PLUG

Your mini bike is equipped with an NGK BP5H or Torch E5T
spark plug. To determine if the standard spark plug is in good
condition, check the color of the plug's center electrode in-
sulator after vehicle operation. A brown color indicates that
the plug is correct. A white or dark insulator indicates that the
engine may need adjustment or another plug type may be
needed. Consult your authorized dealer or Baja Motorsports
if your plug insulator is not a light brown color.
NOTE: This mini bike uses a resistor-type spark plug to avoid
jamming electronic parts. Improper spark plug selection may
cause electronic interference with your mini bike's ignition
system, resulting in the vehicle performance problems. It
could also have an incorrect fit or heat range for your en-
gine, which could cause severe engine damage and void the
warranty. Use only recommended spark plugs: NGK BP5H,
Torch E5T, or suitable equivalent.
To install a spark plug, turn it in as far as possible with your
fingers, then tighten it with a wrench about 1/2 turn past
finger tight (if the spark plug is new) or 1/4 turn past finger
tight (if you are reinstalling the old spark plug). Be careful
not to cross-thread the spark plug, which could damage the
aluminum threads of the cylinder head.
To maintain a proper functioning spark plug, keep the plug
free of carbon. Remove carbon from the plug with a wire or
pin and adjust the gap to 0.028-0.031 in. (0.7-0.8 mm) for
good ignition. Use a thickness gauge to check the gap.
MAINTENANCE
NOTICE:
Keep the spark plug hole covered while the spark plug
is removed so that dirt does not enter the open hole. Dirt
entering the spark plug hole in the cylinder could damage
engine parts that move.
CHANGING/ADDING ENGINE LUBRICANT
Engine lubricant has a major influence on engine perfor-
mance and service life. Engine lubricant level should be
checked before each use of the mini bike.
For best engine performance, change the lubricant every 20
to 40 hours of operation. In dirty and dusty areas, the lubricant should be changed more often.
Reference the chart below for the appropriate engine lubricant
to use based on the temperature range in your area.
NOTE: In very cold weather [below 5°F (15°C)], use
SAE10W-50 for good starting and smooth operation.
ENGINE
LUBRICANT
TEMP.
Always use a 4-stroke motor lubricant that meets or exceeds
the requirements for API service classification SJ. Check
lubricant level before each use.
NOTE: Non-detergent or 2-stroke engine lubricants will dam-
age the engine and should not be used.
To check lubricant level:
 Park vehicle on level ground and lower side stand.
 Unscrew the oil cap/dipstick and remove.
 Wipe dipstick clean; re-seat and rethread in hole.
 Remove the dipstick and inspect the lubricant level. Level
should be between the minimum and maximum marks on
the dipstick.
 If lubricant is below minimum mark on dipstick, add lu-
bricant until level falls between minimum and maximum
marks on the dipstick.
To change engine lubricant:
Lubricant should be changed while the engine lubricant is still
warm, but not hot. This allows the lubricant to drain quickly
and completely.
Do not change engine lubricant while it is hot. Accidental
contact with hot engine lubricant could result in serious
burns.
