“broken in”. Therefore, it is ad-
visable before doing any high-
speed riding to ride conserva-
tively for approximately 100 km
(60 mi) after installing a new tire.
●
The tires must be warmed up
before a high-speed run.
●
Always adjust the tire air pres-
sure according to the operating
conditions.
EAU21962
Cast wheels To maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.●
The wheel rims should be checked
for cracks, bends, warpage or oth-
er damage before each ride. If any
damage is found, have a Yamaha
dealer replace the wheel. Do not
attempt even the smallest repair to
the wheel. A deformed or cracked
wheel must be replaced.
●
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.

Adjusting the clutch lever free
play The clutch lever free play should mea-
sure 10.0–15.0 mm (0.39–0.59 in) as
shown. Periodically check the clutch le-
ver free play and, if necessary, adjust it
as follows.
To increase the clutch lever free play,
turn the clutch lever free play adjusting
bolt at the clutch lever in direction (a).
To decrease the clutch lever free play,
turn the adjusting bolt in direction (b).1. Clutch lever free play adjusting bolt

4. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal,
including chrome- and nickel-plat-
ed, surfaces.
5. Use spray oil as a universal clean- er 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 completely before storing or covering it.
WARNING
EWA11131
Contaminants on the brakes or tires
can cause loss of control.●
Make 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 ac-
etone, and wash the tires with
warm water and a mild deter-
gent. Before riding at higher
speeds, test the motorcycle’s
braking performance and cor-
nering behavior.
NOTICE
ECA10800
●
Apply spray oil and wax spar-
ingly and make sure to wipe off
any excess.
●
Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.
●
Avoid using abrasive polishing
compounds as they will wear
away the paint.
TIP●
Consult a Yamaha dealer for ad-
vice on what products to use.
●
Washing, rainy weather or humid
climates can cause the headlight
lens to fog. Turning the headlight
on for a short period of time will
help remove the moisture from the
lens.
EAU26182
Storage Short-term
Always store your motorcycle in a cool,
dry place and, if necessary, protect it
against dust with a porous cover. Be
sure the engine and the exhaust sys-
tem are cool before covering the motor-
cycle.NOTICE
ECA10810
●
Storing the motorcycle in a
poorly ventilated room or cover-
ing it with a tarp, while it is still
wet, will allow water and humid-
ity to seep in and cause rust.
●
To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
Long-term
Before storing your motorcycle for sev-
eral months:1. Follow all the instructions in the “Care” section of this chapter.

72. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
3. Perform the following steps to pro- tect the cylinders, piston rings, etc.
from corrosion.a. Remove the spark plug caps and spark plugs.
b. Pour a teaspoonful of engine oil into each spark plug bore.
c. Install the spark plug caps onto the spark plugs, and then place
the spark plugs on the cylinder
head so that the electrodes are
grounded. (This will limit spark-
ing during the next step.)
d. Turn the engine over several times with the starter. (This will
coat the cylinder walls with oil.)
WARNING! To prevent dam- age or injury from sparking,
make sure to ground the
spark plug electrodes while
turning the engine over.
[EWA10951]
e. Remove the spark plug caps from the spark plugs, and then
install the spark plugs and the
spark plug caps.
4. Lubricate all control cables and the pivoting points of all levers and
pedals as well as of the side-
stand/centerstand.
5. Check and, if necessary, correct the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
6. Cover the muffler outlet with a plastic bag to prevent moisture
from entering it.
7. Remove the battery and fully charge it. Store it in a cool, dry
place and charge it once a month.
Do not store the battery in an ex-
cessively cold or warm place [less
than 0 °C (30 °F) or more than 30
°C (90 °F)]. For more information
on storing the battery, see page
6-33.
TIPMake any necessary repairs before
storing the motorcycle.
