Tips for reducing fuel con-
sumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
●Turn the starter (choke) off as
soon as possible.
●Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
●Do not rev the engine while shif-
ting down, and avoid high engine
speeds with no load on the engi-
ne.
●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 cros-
sings).

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 following 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 themsel-
ves to the correct operating clearan-
ces. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAUS1560
0–500 km (0–300 mi)
●Avoid prolonged operation above
4000 r/min.
●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 engi-
ne at one set throttle position.500–1000 km (300–600 mi)
●Avoid prolonged operation above
6000 r/min.
●Rev the engine freely through the
gears, but do not use full throttle
at any time. NOTICE:After 1000
km (600 mi) of operation, the
transmission oil must be chan-
ged.
[ECA10370]
1000 km (600 mi) and beyond
●The vehicle can now be operated
normally.
ECA10310
●Keep the engine speed out of
the tachometer red zone.
●If any engine trouble should
occur during the engine break-
in period, immediately have a
Yamaha dealer check the vehi-
cle.
