Tips for reducing fuel con-
sumption
Fuel consumption depends largely on
1
your riding style. Consider the following
tips to reduce fuel consumption:
2
●
Avoid high engine speeds during
acceleration.
● Avoid high engine speeds with no
3
load on the engine.
●
Turn the engine off instead of let-
4
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
5
fic lights or at railroad crossings).

Engine break-in

There 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.
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.

EAU16830 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.
EAU16951
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the speed occasionally.
NOTICE
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
