FUEL, ENGINE OIL
AND COOLANT
RECOMMENDATION
FUEl
Use un leaded gasoline with an oc-
tane rating of91 or higher (Re-
search method). Unleaded gaso-
line can extend spark plug life and
exhaust components life.
If pinking or knocking is experi-
enced, substitute higher octane
grade gasoline or another brand,
because there are differences be-
tween brands.
ENGINE Oil
Use a premium quality 4-stroke
motor oil to ensure longer service
life of your motorcycle. Use only
oils which are rated SE, SF or SG
under the API service classifica-
tion. The recommended viscosity is
SAE 10W-40. If a SAE 10W-40
motor oil is not available, select an
alternative according to the follow-
ing chart.

COOLANT
Use an anti-freeze compatible with
aluminum radiator mixed with dis-
tilled water only at the ratio of
50:50.
WATER FOR
MixiNG
Use distilled waten:JnfY.Water oth-

ANTI-FREEZE
The coolant performs
as
rUst inhibi-
tor and water pump lubricant as
well as anti-freeze. Therefore the
coolant should be used at all times
even though the atmospheric tem-
perature in your area does not go
down to freezing ~oint.

NOTE: Mixing of anti-freeze should
be limited to
60
%.
Mixing beyond
it would reduce its efficiency. If the
anti-freeze mixing ratio is below
30% rust inhibiting performance is'
greatly reduced. Be sure to mix it
above 30% even though the atmo-
spheric temperature does not go
down to freezing point.
BREAK-IN (RUNNING-IN)
The opening explains how impor-
tant proper break-in is to achieve
maximum life and performance
from ybur new Suzuki. The follow-
ing guidelines explain proper break-
in procedures.
MAXIMUM ENGINE SPEED
RECOMMENDATION
This table shows the maximum
recommended engine speed dur'
ing the break-in period.
Initial
800 km
Below
(500 miles)
7000 r/min
Up to
1600 km
. Below
(1000 miles)
10000 r/min
Over
1600 km
Below
(1000 miles)
16500 r/min
VARY THE ENGINE SPEED
The engine speed should be varied
and not held at a constant speed.
This allows the parts to be "load-
ed" with pressure, and then un-
loaded, allowing the parts to cool.
This aids the mating process of the
parts. It is essential that some
stress be placed on the engine
components during break-in to en-
sure this mating process. Do not,
though, apply excessive load on
the engine.
AVOID CONSTANT lOW SPEED
Operating the engine at con~tant
low speed (light- load) can cause
parts to glaze and not seat in. Allow
the engine to accelerate freely
through the gears, without exceed-
ing the recommended maximum
limits. Do not. however, use full
throttle for the first 1600 km (1000
miles) ..
25
AllOW THE ENGINE OIL TO CIR-
CULATE BEFORE RIDING
Allow sufficient idling tirtie after
warm or cold engine SHIrt Up be-
fore applying load or reVVing the
engine. This allows time for the
lubricating oil to reach all critical
engine components.
OBSERVE YOUR FIRSt AND
MOST CRITICAL SERVICE
The initial service (1000 km main-
tenance) is the most important ser-
vice your motorcycle will receive.
During break-in operation, all of the
engine components will have mat-
ed together and seated. Mainte·
nance required as pari of the initial
service includes correction of all
adjustments, tightening of all fas-
teners and replacement of dirty oil.
Timely performance of this service
will help make sure you get the
best service life and performance
from the engine.
ACAUTION
The 1000 km (600 miles) service
should be performed as outlined in
the INSPECTION AND MAINTE-
NANCE section of this Owner's
Manual. Pay particular attention to
the CAUTION AND WARNING in
that section.
