CAUTION: Never turn off the ignition
switch on a long hill. This may cause the
spark plug to foul, in addition to being un-
safe.
NOTE:
When using engine braking for long periods,
it is very important not to exceed maximum
recommended rpm (tachometer red zone). It
is also necessary to open the throttle occa-
sionally because the engine relies on the fuel
for internal cooling.
Stopping
There are several ways to stop. Pulling in the
clutch lever and twisting the throttle grip in
the close direction will permit you to gradual-
ly glide to a stop.
Downshifting through the gears, using the
drag of the engine to slow down is another.
However, the best method, and the one most
universally used, is to use both engine com-
pression (downshifting through the gears as
the machine slows) and the front and rear
brakes.
When stopping, gradually apply the rear brake
while twisting the throttle grip in the closed
direction. After the rear brake starts to take
hold, gradually apply the front brake. As the
machine continues to slow, shift down
through the gears using engine compression to
aid the slowing effect. When shifting down,
watch the tachometer to see that the engine
does not over-rev.
NOTE:
During periods of inclement weather such as
snow, rain, sleet, or ice or on poor road sur-
faces where traction is minimal, or in a sharp
corner, IT IS NOT ADVISABLE TO FIRMLY
APPLY THE FRONT BRAKE. While it is true
that the front brake supplies the greater por-
tion of braking power, it is also true that
