Periodic maintenance and adjustment
TIP
Be sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.
NOTICE
 In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of "CD" or oils of a high-
er quality than specified. In
addition, do not use oils labeled
"ENERGY CONSERVING II" or
higher.
 Make sure that no foreign mate-
rial enters the crankcase.
15. Check the filler cap O-ring for
damage, and replace it if neces-
sary.
16. Install and tighten the oil filler cap.
17. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
TIP
After the engine is started, the engine
oil level warning light should go off if
the oil level is sufficient.
NOTICE
If the oil level warning light flickers
or remains on even if the oil level is
correct, immediately turn the engine
off and have a Yamaha dealer check
the vehicle.
18. Turn the engine off, and then
check the oil level and correct it if
necessary.
19. Check the dipstick O-ring for
damage, and replace it if neces-
sary.
