Maintenance Fundamentals
NOTICE
Replacing a fuse with one that has a higher
rating greatly increases the chance of damage to
the electrical system.
If a fuse fails repeatedly, you likely have an
electrical fault. Have your scooter inspected by
your authorised dealer.
Engine Oil
Engine oil consumption varies and oil quality
deteriorates according to riding conditions and
time elapsed.
Check the engine oil level regularly, and add the
recommended engine oil if necessary. Dirty oil
or old oil should be changed as soon as
possible.
