GIVE SAFETY THE RIGHT OF WAY
EAU00021
Motorcycles are fascinating vehicles, which can give you an unsurpassed feeling of power and
freedom. However, they also impose certain limits, which you must accept; even the best motorcycle
does not ignore the laws of physics.
1
Regular care and maintenance are essential for preserving value and operating condition of your
motorcycle. Moreover, what is true for the motorcycle is also true for the rider: good performance
depends on being in good shape. Riding under the influence of medication, drugs and alcohol is, of
course, out of the question. Motorcycle riders—more than car drivers—must always be at their mental
and physical best. Under the influence of even small amounts of alcohol, there is a tendency to take
dangerous risks.
Protective clothing is as essential for the motorcycle rider as seat belts are for car drivers and
passengers. Always wear a complete motorcycle suit (whether made of leather or tear-resistant
synthetic materials with protectors), sturdy boots, motorcycle gloves and a properly fitting helmet.
Optimum protective wear, however, should not encourage carelessness. Although full-coverage
helmets and suits, in particular, create an illusion of total safety and protection, motorcyclists will
always be vulnerable. Riders who lack critical self-control run the risk of going too fast and are apt to
take chances. This is even more dangerous in wet weather. The good motorcyclist rides safely,
predictably and defensively—avoiding all dangers, including those caused by others.
Enjoy your ride!

PRE-OPERATION CHECKS
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspection, to check the following points before each ride.

Even with the transmission in
●
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long distances. The transmission is
properly lubricated only when
the engine is running. Inadequate lubrication may damage
the transmission.

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
Thoroughly warm up the engine.
●
Shift up swiftly, and avoid high en-
●
gine speeds during acceleration.
Do not rev the engine while shift-
●
ing down, and avoid high engine
speeds with no load on the engine.
Turn the engine off instead of let-
●
ting it idle for an extended length
of time (e.g., in traffic jams, at traffic lights or at railroad crossings).
EAU01128
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1,600 km. For this reason, you should read the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1,600 km. The various parts in the engine wear and polish themselves to the
correct operating clearances. During
this period, prolonged full-throttle operation or any condition that might result
in engine overheating must be avoided.

Checking the spark plugs
The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic maintenance and lubrication chart. In addition,
the condition of the spark plugs can reveal the condition of the engine.
The porcelain insulator around the center electrode of each spark plug should
be a medium-to-light tan (the ideal color when the motorcycle is ridden normally), and all spark plugs installed in
the engine should have the same color.
If any spark plug shows a distinctly different color, the engine could be defective. Do not attempt to diagnose such
problems yourself. Instead, have a
Yamaha dealer check the motorcycle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.

Troubleshooting
Although Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur during operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems yourself. However, should your motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the motorcycle
properly.
Use only genuine Yamaha replacement parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
