4-2 NOTE:
Pre-operation checks should be made each time the motorcycle is used. Such an inspection can be thoroughly accomplished
in a very short time; and the added safety it assures is more than worth the time involved. If any maintenance service or
adjustment is needed, consult the chart above to refer to the pages in which the service or adjustment is described.
1. The engine, exhaust pipe, and muffler will be very hot after the engine has been run.
Be careful not to touch them or to allow any clothing item to contact them during inspection or repair.
2. If any item is not working properly, have it inspected and repaired before operating the motorcycle.

4-5 Tires
To ensure maximum performance, long service, and safe
operation, note the following:
1. Tire air pressure
Always check and adjust the tire pressure before
operating the machine.
Tire inflation pressure should be checked and adjusted
when the temperature of the tire equals the ambient air
temperature.
Tire inflation pressure must be adjusted according to
total weight of cargo, rider, passenger and accessories
(fairing, saddlebags, etc. if approved for this model),
and vehicle speed.

Always wipe off spilled fuel immediately with a dry and

Make sure there is sufficient fuel in the tank.
Do not overfill the fuel tank. Avoid spilling fuel on the
hot engine. Do not fill the fuel tank above the bottom of
the filler tube as shown in the illustration or it may
overflow when the fuel heats up later and expands.

Total:
10.6 l ( 2.33 Imp gal, 2.80 US gal)
Reserve:
1.0 l ( 0.220 Imp gal, 0.264 Us gal)
Your Yamaha engine has been designed to use regular
unleaded gasoline with a pump octane number ([R+m]/2)
of 86 or higher, or research octane number of 91 or higher.
If knocking or pinging occurs, use a different brand of
gasoline or premium unleaded fuel. Unleaded fuel will give
you longer spark plug life and reduced maintenance cost.
If unleaded gasoline is not available, then leaded regular
gasoline can be used.
Gasohol
There are two types of gasohol; gasohol containing ethanol
and that containing methanol. Gasohol containing ethanol
can be used if ethanol content does not exceed 10%.
Gasohol containing methanol is not recommended by
Yamaha because it can cause fuel system damage or
vehicle performance problems.

5-7Engine Break-in
There is never a more important period in the life of your
motorcycle than the period 1.000Km. For this reason we
ask that you carefully read the following material. Because
the engine is brand new, you must not put an excessive
load on it for the first several hours of running.
During this period, prolonged full throttle operation, or any
condition which might result in excessive heating of the
engine must be avoided.
1. 0 ~ 150 Km:
Avoid operation above 1/3 throttle. Stop the engine and
let it cool for 5 to 10 minutes after every hour of
operation. Vary the speed of the motorcycle from time
to time. Do not operate it at one set throttle position. Your motorcycle’s fuel consumption depends to a large
extent on your riding style. The following tips can help
reduce fuel consumption.
1. Warm up the engine before riding.
2. Turn off the starter lever as soon as possible.
3. Shift up swiftly and avoid high engine speeds during
acceleration.
4. Do not double-clutch or rev the engine while shifting down
and avoid high engine speeds with no load engine.
5. Turn off the engine instead of letting it idle for an extended
lenght of time, i.e. in traffic jams, at traffic lights or railroad
crossings.Tips for reducing fuel consumption

5-8 2. 150 ~ 500 Km:
Avoid prolonged operation above 1/2 throttle. Allow the
machine to rev freely through the gears, but do not use
full throttle at any time.
3. 500 ~ 1,000 Km:
Avoid cruising speeds in excess of 3/4 throttle.
CAUTION:
After 1,000Km of operation, be sure to replace the
engine oil.
4. After 1,000 Km:
Avoid prolonged full throttle operation. Vary speeds
occasionally.Parking
When parking the motorcycle, stop the engine and remove
the ignition key. Turn the fuel cock to “OFF” whenever
stopping the engine.
CAUTION:
If any engine trouble should occur during the break-in
period, consult a Yamaha dealer immediately.
The muffler and exhaust pipe are hot. Park the
motorcycle in a place where pedestrians or children
are not likely to touch the motorcycle. Do not park the
motorcycle on a slope or soft ground; the motorcycle
may fall over.
