lubrication
EW000112
WARNING
Damage to the outer housing of ca-
bles may lead to internal rusting
and interfere with the cable move-
ment. Replace damaged cables as
soon as possible to prevent unsafeconditions.
Lubricate the cables and cable ends. If
a cable does not operate smoothly,
ask a Yamaha dealer to replace it.
Recommended lubricant:
Engine oil
EAU00773
Throttle cable and grip lubri-
cationThe throttle twist grip assembly should
be greased at the time that the cable is
lubricated, since the grip must be re-
moved to get at the end of the throttle
cable. After removing the screws, hold
the end of the cable up in the air and
put in several drops of lubricant. With
the throttle grip disassembled, coat the
metal surface of the grip assembly with
a suitable all-purpose grease.

Supporting the motorcycleSince the Yamaha XVS650/XVS650A
has no centerstand, follow these pre-
cautions when removing the front and
rear wheel or performing other mainte-
nance requiring the motorcycle to
stand upright. Check that the motor-
cycle is in a stable and level position
before starting any maintenance. A
strong wooden box can be placed un-
der the engine for added stability.
Front wheel service
To stabilize the rear of the motorcycle,
either use a motorcycle stand or place
a motorcycle jack under the frame in
front of the rear wheel to prevent it
from moving from side to side. Then
use a motorcycle stand to elevate the
front wheel off of the ground.
Rear wheel service
Use a motorcycle stand or motorcycle
jack to elevate the motorcycle so the
rear wheel is off the ground. Alterna-
tively, two jacks can be placed under
the frame or swingarm.

1. Clean your motorcycle with cold
water and soap after the engine
has cooled down.

ECA00012
CAUTION:
Do not use warm water since it in-
creases the corrosive action of the

salt.
2. Be sure to apply a corrosion pro-
tection spray on all (even chrome-
and nickel-plated) metal surfaces
to prevent corrosion.
After cleaning
1. Dry the motorcycle with a cham-
ois or an absorbing cloth.
2. Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally in-
duced discoloring of stainless-
steel exhaust systems can be re-
moved through polishing.)
3. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all (even chrome-
and nickel-plated) metal surfaces.
4. Use spray oil as a universal clean-
er to remove any remaining dirt.
5. Touch up minor paint damage
caused by stones, etc.
6. Wax all painted surfaces.
7. Let the motorcycle dry completely
before storing it or covering it.

EWA00001
WARNING

Make sure that there is no oil or wax
on the brakes and tires. If neces-
sary, clean the brake discs and lin-
ings with a regular brake disc
cleaner or acetone, and wash the
tires with warm water and mild
soap. Then, carefully test the motor-
cycle for its braking performance
and cornering behavior.
ECA00013
CAUTION:

l
Apply spray oil and wax spar-
ingly and wipe off any excess.
l
Never apply oil or wax on rubber
and plastic parts, but treat them
with a suitable care product.
l
Avoid using abrasive polishing
compounds as they wear away
the paint.
NOTE:

Consult a Yamaha dealer for advice on
what products to use.
