1-6 GENERAL INFORMATION
ENGINE COOLANT
Use an anti-freeze/engine coolant compatible with an aluminum radiator, mixed with distilled water only.
WATER FOR MIXING
Use distilled water only. Water other than distilled water can corrode and clog the aluminum radiator.
ANTI-FREEZE/ENGINE COOLANT
The engine coolant perform as a corrosion and rust inhabit as well as anti-freeze. Therefore, the engine
coolant should be used at all times even though the atmospheric temperature in your area does not go down
to freezing point.
Suzuki recommends the use of SUZUKI COOLANT anti-freeze/engine coolant. If this is not available, use an
equivalent which is compatible with an aluminum radiator.
LIQUID AMOUNT OF WATER/ENGINE COOLANT
Solution capacity (total): 2 400 ml (2.5/2.1 US/lmp qt)
For engine coolant mixture information, refer to cooling system section. (
5-2)
Mixing of anti-freeze/engine coolant should be limited to 60%. Mixing beyond it would reduce its
efficiency. If the anti-freeze/engine coolant mixing ratio is below 50%, rust inhabiting performance
is greatly reduced. Be sure to mix it above 50% even though the atmospheric temperature does
not go down to the freezing point.
BREAK-IN PROCEDURES
During manufacture only the best possible materials are used and all machined parts are finished to a very
high standard but it is still necessary to allow the moving parts to “BREAK-IN” before subjecting the engine to
maximum stresses. The future performance and reliability of the engine depends on the care and restraint
exercised during its early life. The general rules are as follows.
• Keep to these break-in procedures:
Initial
800 km ( 500 miles): Below 7 000 r/min
Up to 1 600 km (1 000 miles): Below 10 500 r/min
Over to 1 600 km (1 000 miles): Below 14 000 r/min
• Upon reaching an odometer reading of 1 600 km (1 000 miles) you can subject the motorcycle to full throttle
operation. However, do not exceed 14 000 r/min at any time.
CYLINDER IDENTIFICATION
The four cylinders of this engine are identified as No.1, No.2, No.3
and No.4 cylinder, as counted from left to right (as viewed by the
rider on the seat).
