Maintenance Fundamentals
Fuses
Fuses protect the electrical circuits on your
motorcycle. If something electrical on your
motorcycle stops working, check for and
replace any blown fuses.
#
Inspecting and Replacing Fuses
Turn the ignition switch to the
to remove and inspect fuses. If a fuse is blown,
replace with a fuse of the same rating. For fuse
ratings, see "Specifications."
NOTICE
Replacing a fuse with one that has a higher
rating greatly increases the chance of damage to
the electrical system.

Blown fuse
If a fuse fails repeatedly, you likely have an
electrical fault. Have your motorcycle inspected
by your 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.

Selecting the Engine Oil
