Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1,000 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
1,000 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.
EAU17010
0–500 km (0–300 mi)
Avoid prolonged operation above 1/3
throttle.
500–1,000 km (300–600 mi)
Avoid prolonged operation above 1/2
throttle.
CAUTION:
ECA11150
After 1,000 km (600 mi) of operation,
the engine oil must be changed, and
the oil filter element replaced.
1,000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.
CAUTION:
ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

ans or children are not likely to
touch them.
