ENGINE OIL
Engine Oil Level Check
Check the engine oil level each day before
operating the motorcycle.
The oil fill cap/dipstick (1) is at the rear of
the right crankcase cover and contains a
dipstick for measuring the oil level. Oil level
must be maintained between the upper (2)
and lower (3) level marks on the oil fill cap/
dipstick.
1. Hold the motorcycle upright on firm
level ground.
2. Start the engine and let it idle for 3—5
minutes.
3. Stop the engine. After 2—3 minutes,
remove the oil fill cap/dipstick, wipe it
clean, and reinsert the oil fill cap/
dipstick without screwing it in. Remove
the oil fill cap/dipstick. The oil level
should be between the upper and lower
level marks on the oil fill cap/dipstick.

4. If required, add the specified oil (see
page 55) up to the upper level mark. Do
not overfill.
5. Reinstall the oil fill cap/dipstick. Check
for oil leaks.
Running the engine with insufficient oil can
cause serious engine damage.
