Tips for reducing fuel con-
sumption
Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
G
Shift up swiftly, and avoid high en-
gine speeds during acceleration.
G
Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.
G
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).
OPERATION AND IMPORTANT RIDING POINTS
EAU16810

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.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided.
0–500 km (0–300 mi)
Avoid prolonged operation above 6000
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 engine at one
set throttle position.
EAU16830
500–1000 km (300–600 mi)
Avoid prolonged operation above 8000
r/min.
Rev the engine freely through the
gears, but do not use full throttle at any
time.
CAUTION:
After 1000 km (600 mi) of operation,
the engine oil must be changed, the
oil filter cartridge or element re-
placed, and the oil strainer cleaned.
1000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.
CAUTION:
