TIPService the air filters more frequently when
operating in wet or dusy environments. Whenever air filter maintenance is performed:
check the air inlet for obstructions and the
air filter case for dirt and foreign matter.
check the air filter case check hoses for dirt
or water and clean as necessary.
check the air filter cas e joints and the rub-
ber joints to and from the throttle body for
proper fit and sealing.
tighten all fittings securely to avoid the pos-
sibility of unfiltered air entering the engine.NOTICEECB02270Never operate the engine with the air filter
element removed. Doing so would allow
unfiltered air to enter, causing rapid en-
gine wear and possible engine damage. Additionally, the fuel injection system
would be affected, resulting in poor engine
performance and possible overheating.
Clean the primary air filter as follows.
1. Remove panel C (page 8-10).
2. Remove the air filter case cover by turn- ing the air filter case cover lock counter-
clockwise.TIPMake sure that the match mark on the cover
lock is aligned with the open match mark on
the air filter case cover.

sure the lining thickness. If a brake pad is
damaged or if the lining thickness is less than
1.0 mm (0.04 in), have a Yamaha dealer re-
place the brake pads as a set.
The wheels need to be removed to check the
brake pads. (See pages 8-54, 8-56 for wheel

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.
TIPIf it is difficult to get the recommended coolant, tap water can be used temporarily, provided that
it is changed to the recommended coolant as soon as possible. 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
