Keep in mind that braking on a
wet road is much more difficult.
Ride slowly down a hill, as bra-
king downhill can be very diffi-
cult.
EAU16830
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 engi-
ne wear and polish themselves to the
correct operating clearances. During this
period, prolonged full-throttle operation
or any condition that might result in engi-
ne overheating must be avoided.
EAU17150
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.
ECA10370
CAUTION
After 1000 km (600 mi) of operation,
the transmission oil must be chan-
ged.
1000 km (600 mi) and beyond
Avoid prolonged full-throttle opera-
tion. Vary the engine speed occasio-
nally.
