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 follow-
ing 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.
EAU17123
0–1000 km (0–600 mi)
Avoid prolonged operation above 4500
r/min. NOTICE: After 1000 km (600
mi) of operation, the engine oil and
final gear oil must be changed, and
the oil filter cartridge or element re-
placed.
[ECA10332]
1000–1600 km (600–1000 mi)

WARNING
EWA14522
Always stop the engine using
the main switch. When the en-
gine stop switch has been used
in an emergency, be sure to ap-
ply the front or rear brake while
the main switch is still on, as the
clutch automatically disengag-
es a few seconds after the en-
gine is turned off, and the rear
wheel will move freely.
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.

WARNING

Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the de-
tent to allow any residual pressure to escape. When the hissing sound has stopped, press down on the capwhile turning it counterclockwise, and then remove the cap.
TIPIf coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolantas soon as possible.
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
