Recommended shift points
(for Switzerland only)The recommended shift points are
shown in the table below.CF-25ENOTE:@ When shifting two gears down from 4th
to 2nd, bring your motorcycle to a
speed of 35 km/h. @

Tips for reducing fuel
consumptionYour motorcycle’s fuel consumption
depends to a large extent on your
riding style. The following tips can help
reduce fuel consumption:l
Warm up the engine before riding.
l
Turn off the starter (choke) as
soon as possible.
l
Shift up swiftly and avoid high en-
gine speeds during acceleration.
l
Do not double-clutch or rev the en-
gine while shifting down and avoid
high engine speeds with no load
on the engine.
l
Turn off the engine instead of let-
ting it idle for an extended length
of time, i.e. in traffic jams, at traffic
lights or railroad crossings.
EAU01128
Engine break-inThere is never a more important period
in the life of your motorcycle than the
period between zero and 1,600 km. For
this reason we ask that you carefully
read the following material. Because
the engine is brand new, you must not
put an excessive load on it for the first
1,600 km. The various parts in the en-
gine wear and polish themselves to the
correct operating clearances. During
this period, prolonged full throttle oper-
ation, or any condition which might re-
sult in excessive heating of the engine,
must be avoided.

them to the specified torque.
6. Apply a light coat of engine oil to
the O-ring of the new oil filter.
NOTE:@ Make sure the O-ring is seated proper-
ly. @
7. Install the oil filter and tighten it to
the specified torque with an oil fil-
ter wrench.
8. Pour only 2.5 L of oil into the oil fill-
er hole, then install the oil filler cap
and tighten it.
9. Start the engine and rev it several
times.
10. Stop the engine and remove the
oil filler cap.11. Gradually fill the oil tank with the
remainder of the recommended oil
quantity while checking the level
on the dipstick.

CAUTION:@ l
Do not put in any chemical addi-
tives. Engine oil also lubricates
the clutch and additives could
cause clutch slippage.

Be sure no foreign material en-
ters the crankcase.

WheelsTo ensure maximum performance,
long service, and safe operation, note
the following:l
Always inspect the wheels before
a ride. Check for cracks, bends or
warpage of the wheel. Be sure the
spokes are tight and undamaged.
If any abnormal condition exists in
a wheel, consult a Yamaha dealer.
Do not attempt even small repairs
to the wheel. If a wheel is de-
formed or cracked, it must be re-
placed.
l
Tires and wheels should be bal-
anced whenever either one is
changed or replaced. Failure to
have a wheel balanced can result
in poor performance, adverse han-
dling characteristics, and short-
ened tire life.
l
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it to
develop its optimal characteristics.

WARNING
@ l
Check the brake lever free play.
Be sure the brake is working
properly.
l
A soft or spongy feeling in the
brake lever can indicate the
presence of air in the brake sys-
tem. This air must be removed
by bleeding the brake system
before the motorcycle is operat-
ed. Air in the system will cause
greatly diminished braking ca-
pability and can result in loss of
control and an accident. Have a
Yamaha dealer inspect and
bleed the system if necessary.

CAUTION:Be sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled
“Energy Conserving”) contain anti-friction additives which
will cause clutch and/or starter clutch slippage, resulting in
reduced component life and poor engine performance.
