be held responsible for property
damage or personal injury that may
result from improper handling.
8Do not tamper with or attempt
to open the gas cylinder.
8Do not subject the shock
absorber to an open flame or
other high heat sources, other-

MOTORCYCLE CARE AND STORAGE
7 After cleaning
1. Dry the motorcycle with a
chamois or an absorbing cloth.
2. Immediately dry the drive chain
and lubricate it to prevent it from
rusting.
3. Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally
induced discoloring of stainless-
steel exhaust systems can be
removed through polishing.)
4. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal, includ-
ing chrome- and nickel-plated,
surfaces.
5. Use spray oil as a universal
cleaner to remove any remaining
dirt.6. Touch up minor paint damage
caused by stones, etc.
7. Wax all painted surfaces.
8. Let the motorcycle dry complete-
ly before storing or covering it.

8Make sure that there is no oil
or wax on the brakes or tires.
If necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or
acetone, and wash the tires
with warm water and a mild
detergent.
8Before operating the motorcy-
cle test its braking perfor-
mance and cornering behav-
ior.

8Apply spray oil and wax spar-
ingly and make sure to wipe
off any excess.
8Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.
8Avoid using abrasive polish-
ing compounds as they will
wear away the paint.
NOTE:
Consult a Yamaha dealer for advice
on what products to use.
