2. With the engine stopped, check
the oil level through the level win-
dow located at the lower part of
the left side crankcase cover.
NOTE:

Wait a few minutes until the oil level
settles before checking.

Carburetor adjustmentThe carburetors are important parts of
the engine and require very sophisti-
cated adjustment. Most adjustments
should be left to a Yamaha dealer who
has the professional knowledge and
experience to do so. However, the idle
speed may be adjusted by the owner
as part of routine maintenance.
EC000095
CAUTION:
The carburetors were set at the
Yamaha factory after many tests. If
they are changed, poor engine per-formance and damage may result.

Idle speed adjustmentNOTE:A diagnostic tachometer must be usedfor this procedure.
1. Attach the tachometer. Start the
engine and warm it up for a few
minutes at approximately 1,000 to
2,000 r/min. Occasionally rev the
engine to 4,000 to 5,000 r/min.
The engine is warm when it quick-
ly responds to the throttle.
1. Throttle stop screw2. Set the idle to the specified en-
gine speed by adjusting the throt-
tle stop screw. Turn the screw in
direction a to increase engine
speed and in direction b to de-
crease engine speed.NOTE:If the specified idle speed cannot be
obtained by performing the above ad-justment, consult a Yamaha dealer.Standard idle speed:
1,150 ~ 1,250 r/min

inspectionThere should be a free play of 4 ~
6 mm at the throttle grip. If the free play
is incorrect, ask a Yamaha dealer to
make this adjustment.
EAU00637
Valve clearance adjustmentThe correct valve clearance changes
with use, resulting in improper fuel/air
supply or engine noise. To prevent
this, the valve clearance must be ad-
justed regularly. This adjustment how-
ever, should be left to a professional
Yamaha service technician.

Cable inspection and
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.

Front fork inspectionVisual check
EW000115
WARNING
Securely support the motorcycle sothere is no danger of it falling over.
Check for scratches or damage on the
inner tube and excessive oil leakage
from the front fork.
Operation check
1. Place the motorcycle on a level
place.
2. Hold the motorcycle in an upright
position and apply the front brake.
3. Push down hard on the handle-
bars several times and check if
the fork rebounds smoothly.
EC000098
CAUTION:
If any damage or unsmooth move-
ment is found with the front fork,consult a Yamaha dealer.
EAU00794
Steering inspectionPeriodically inspect the condition of
the steering. Worn out or loose steer-
ing bearings may be dangerous. Place
a stand under the engine to raise the
front wheel off the ground. Hold the
lower end of the front forks and try to
move them forward and backward. If
any free play can be felt, ask a
Yamaha dealer to inspect and adjust
the steering. Inspection is easier if the
front wheel is removed.

CAUTION:
Do not over-tighten the screws asthe lens may break.
EAU01579
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.
