OPERATION AND IMPORTANT RIDING POINTS

EAU16830
Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1000 km (600 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances. Dur-
ing this period, prolonged full-throttle
operation or any condition that might
result in engine overheating must be
avoided. Fuel consumption, tips for reducing
Engine break-in
EAU16820
Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:●
Avoid high engine speeds during
acceleration.
●
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 traf-
fic lights or at railroad crossings).
EAU16951
0 ~ 150 km (0 ~ 90 mi)
Avoid prolonged operation above 1/3
throttle.
After every hour of operation, stop the
engine, and then let it cool for five to
ten minutes.Vary the engine speed from time to time.
Do not operate the engine at one set
throttle position.
150 ~ 500 km (90 ~ 300 mi)
Avoid prolonged operation above 1/2
throttle.
Rev the engine freely through the gears,
but do not use full throttle at any time.
500 ~ 1000 km (300 ~ 600 mi)
Avoid prolonged operation above 3/4
throttle.
NOTICE:
After 1000 km (600
mi) of operation, the engine oil must
be changed and the oil strainer
cleaned.
[ECA10351]
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the speed occasionally.

NOTICEIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

WARNING
8 88 8
8Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.

8Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the
detent to allow any residual pressure to escape. When the hissing sound has stopped, press down on the cap
while turning it counterclockwise, and then remove the cap.TIP
If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolant
as soon as possible.
