Operation and important riding points

EAU15952

Engine break-in

There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the fol-
EWA10272 lowing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 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.
0–1000 km (0–600 mi)
Avoid prolonged operation above 1/3
throttle. NOTICE: After 1000 km (600
mi) of operation, be sure to replace
the engine oil and final transmission
oil.
[ECA11662]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 1/2
throttle.
1600 km (1000 mi) and beyond
EAU16842
The vehicle can now be operated nor-
mally.
NOTICE
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
