There are also three (3) pair of unmarked
lines. They indicate the Full Advance firing
range for each cylinder.

The above procedure i s recommended for set-

information i s provided so that the position of
the static pointer can be verified using a degree

D. Battery
A poorly maintained battery will deteriorate quickly.
The battery fluid should be checked a t least once a
month.
1. The level should be between the upper and
lower level marks. Use only distilled water for
refilling. Normal tap water contains minerals
which are harmful to a battery; therefore, re-
fill only with distilled water.
2. Always make sure the connections are correct
when installing the battery. The red lead i s for
the (+) terminal and the black lead is for the
terminal. Make sure the breather pipe i s
(-)
properly connected, properly routed, and is
not damaged or obstructed.
NOTE:
The battery must be charged before
using to insure maximum performance. Failure
t o properly charge the battery before first use,
or a low electrolyte level, will cause premature
failure of the battery.
Charging current: 1.4 Amps
Charging hours: 10 hrs.
E. Spark Plug
The spark plug indicates how the engine i s operating.
If the engine is operating correctly. and the machine
is being ridden properly, the tip of the white insulator
around the positive electrode of the spark plug will be
a medium tan color. I f the insulator is very dark brown
or black color, then a plug with
might be required. This situation is quite common
during the engine break-in period. If the insulator tip
shows a very light tan or white color or is actually
pure white and glazed, or if electrodes show signs of
melting, then a spark plug with a colder heat range is
required. Remember, the insulator area surrounding
the positive electrode of the spark plug must be a
medium tan color. I f it is not, check carburetion,
timing and ignition adjustments.
