Engine Break-In; Parking - Yamaha YZF-R15A Owner's Manual

OPERATION AND IMPORTANT RIDING POINTS

Engine break-in

There is never a more important peri-
od 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 engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheating
6
must be avoided.
0–500 km (0–300 mi)
Avoid prolonged operation above
5000 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
7500 r/min.
Rev the engine freely through the
gears, but do not use full throttle at
any time. NOTICE: After 1000 km
(600 mi) of operation, the engine oil
must be changed, the oil filter car-
tridge or element replaced, and the
oil strainer cleaned.
1000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.
NOTICE
● Keep the engine speed out of
EAU16981

If any engine trouble should
occur during the engine break-
in period, immediately have a
Yamaha dealer check the vehi-
cle.

Parking

WARNING
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 ve-
hicle may overturn, increasing
the risk of a fuel leak and fire.
Do not park near grass or other
flammable materials
might catch fire.
