Removal and Installation" in Section 9D (Page 9D-
1).
2) Hold the motorcycle in an upright position on a level

The oil level measurement may become
inaccurate unless the motorcycle is held
upright as the motorcycle inclination affects
the oil level.
3) Start and run the engine at idling speed for three
minutes.
NOTE
Do not run the engine at a speed higher than
idling, otherwise the oil level to be inspected
may be affected.
4) Stop and leave the engine standstill for two minutes.
Thereafter if oil flows out when the engine oil level
check bolt (1) is removed, the oil level is appropriate.
If oil is excessive, let oil flows out of the oil level hole.
If oil still does not come out, tighten the oil check
bolt, remove the filler cap (2) and pour an adequate
amount of recommended oil.
WARNING
!
When removing the oil filler cap to avoid the
risk of being burned, do not touch the
