OPERATION
EBU31880Read the Owner’s Manual carefully to be-
come familiar with all controls. If there is a
control or function you do not understand,
ask your Yamaha dealer.
WARNING
EWB03290Failure to familiarize yourself with the con-
trols can lead to loss of control, which
could cause an accident or injury. EBU35720Engine break-inThere is never a more important period in the
life of your vehicle than the period between 0
and 20 hours.
For this reason, we ask that you read the fol-
lowing material carefully. Because the engine
is brand new, you must not put an excessive
load on it for the first several hours of opera-
tion. During the first 20 hours, the variousparts in the engine wear and polish them-
selves to achieve the correct operating clear-
ances.
During this period, prolonged full-throttle op-
eration or any condition that might result in
excessive engine heating must be avoided.
However, momentary (2–3 seconds maxi-
mum) full-throttle operation under load does
not harm the engine.
Each full-throttle acceleration sequence
should be followed with a substantial rest pe-
riod for the engine, by cruising at lower r/min
so the engine can rid itself of the temporary
build-up of heat. If any abnormality is noticed
during this period, consult a Yamaha dealer.
0–10 hours:
Avoid prolonged operation above 5300 r/min.
Allow a cooling-off period of 5 to 10 minutes
after every hour of operation. Vary the speed
of the vehicle from time to time. Do not oper-
ate it at one set throttle position.UB5J7CE0.book Page 1 Thursday, November 26, 2020 1:37 PM

it with coolant as soon as possible,
otherwise the cooling system will not
be protected against frost and corro-
sion. If water has been added to the
coolant, have a Yamaha dealer check
the antifreeze content of the coolant
as soon as possible, otherwise the ef-
fectiveness of the coolant will be re-
duced.
[ECB01012]
6. Install the panel when finished servicing
the vehicle. To change the coolant
The coolant must be changed at the intervals
specified in the periodic maintenance chart.
Have a Yamaha dealer change the coolant.
WARNING! Never attempt to remove the
radiator cap when the engine is hot.

Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you.
[EWB03460]
Place a thick rag over the cap and remove the cap slowly to allow any re-
maining pressure to escape.
TIP Tap water can be used in an emergency. Ch ange to the recommended coolant as soon as
possible.
 The engine will tend to overheat if the radiator is caked with mud, or if air was not properly bled
from the cooling system. Wait until the
engine has cooled.
Check the coolant level in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See TIP.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.
