You can find yourself in an emergency
the moment something goes wrong
with your motorcycle. In dealing with
any mechanical problem, take into
account the road and traffic conditions
you face. Here are some guidelines
that can help you handle mechanical
problems safely.
Tire Failure
You will seldom hear a tire go flat.
If the motorcycle starts handling
differently, it may be a tire failure. This
can be dangerous. You must be able to
tell from the way the motorcycle reacts.
If one of your tires suddenly loses air,
react quickly to keep your balance. Pull
off and check the tires.
If the front tire goes flat, the steering
will feel "heavy." A front-wheel flat is
particularly hazardous because it affects
your steering. You have to steer well to
keep your balance.
If the rear tire goes flat, the back of
the motorcycle may jerk or sway from
side to side.
If either tire goes flat while riding:
• Hold handgrips firmly, ease off the
throttle, and keep a straight course.
• If braking is required, gradually
apply the brake of the tire that isn't
flat, if you are sure which one it is.
• When the motorcycle slows,
edge to the side of the road,
squeeze the clutch and stop.
Stuck Throttle
Twist the throttle back and forth
several times. If the throttle cable is
stuck, this may free it. If the throttle
stays stuck, immediately operate the
engine cut-off switch and pull in the
clutch at the same time. This will remove
power from the rear wheel, though
engine sound may not immediately
decline. Once the motorcycle is "under
control," pull off and stop.
After you have stopped, check the
throttle cable carefully to find the source
of the trouble. Make certain the throttle
works freely before you start to ride again.
Wobble
A "wobble" occurs when the front
wheel and handlebars suddenly start
to shake from side to side at any
speed. Most wobbles can be traced to
improper loading, unsuitable accessories
or incorrect tire pressure. If you are
carrying a heavy load, lighten it. If you
can't, shift it. Center the weight lower
and farther forward on the motorcycle.
Make sure tire pressure, spring pre-
load, air shocks and dampers are at the
settings recommended for that much
weight. Make sure windshields and
fairings are mounted properly.
Check for poorly adjusted steering;
worn steering parts; a front wheel that
is bent, misaligned, or out of balance;
loose wheel bearings or spokes; and
worn swingarm bearings. If none of
these is determined to be the cause,
have the motorcycle checked out
thoroughly by a qualified professional.
Trying to "accelerate out of a
wobble" will only make the motorcycle
more unstable. Instead:
• Grip the handlebars firmly, but
don't fight the wobble.
• Close the throttle gradually
to slow down. Do not apply the
brakes; braking could make the
wobble worse.
• Move your weight as far forward
and down as possible.
• Pull off the road as soon as you
can to fix the problem.
