Engine break-in There is never a more important period
in the life of your engine than the period

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 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.
EAU45581
0–150 km (0–90 mi)
Avoid prolonged operation above 1/3
throttle.
150–500 km (90–300 mi)
Avoid prolonged operation above 1/2
throttle.
500–1000 km (300–600 mi)
Avoid prolonged operation above 3/4
throttle. NOTICE: After 1000 km (600
mi) of operation, be sure to changethe engine oil and final transmission
oil, and to clean the oil strainer.
[ECA16501]1000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.NOTICE
ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
EAU17213
Parking When parking, stop the engine, and
then remove the key from the main
switch.
WARNING
EWA10311
Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them and be burned.
Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn, increasing the
risk of a fuel leak and fire.
Do not park near grass or other
flammable materials which
might catch fire.
