•Battery connection in reverse polarity is strictly prohibited. Such a wrong connection will damage the components of the FI and ABS systems instantly when reverse power is applied.
I718H1000004-01
•Removing any battery terminal of a running engine is strictly prohibited. The moment such removal is made, damaging counter electromotive force will be applied to the electronic unit which may result in serious damage.
I310G1000011-01
00-5 Precautions:
•Before measuring voltage at each terminal, check to make sure that battery voltage is 11 V or higher. Terminal voltage check with a low battery voltage will lead to erroneous diagnosis.
I310G1000012-01
•Never connect any tester (voltmeter, ohmmeter, or whatever) to the electronic unit when its coupler is disconnected. Otherwise, damage to electronic unit may result.
•Never connect an ohmmeter to the electronic unit with its coupler connected. If attempted, damage to ECM or sensors may result.
•Be sure to use a specified voltmeter/ohmmeter. Otherwise, accurate measurements may not be obtained and personal injury may result.
Electrical Circuit Inspection Procedure
While there are various methods for electrical circuit inspection, described here is a general method to check for open and short circuit using an ohmmeter and a voltmeter.
Open circuit check
Possible causes for the open circuit are as follows. As the cause can exist in the connector/coupler or terminal, they need to be checked carefully.
•Loose connection of connector/coupler
•Poor contact of terminal (due to dirt, corrosion or rust, poor contact tension, entry of foreign object etc.)
•Wire harness being open.
•Poor terminal-to-wire connection.
When checking system circuits including an electronic control unit such as ECM, ABS control unit/HU, etc., it is important to perform careful check, starting with items which are easier to check.
1)Disconnect the negative (–) cable from the battery.
2)Check each connector/coupler at both ends of the circuit being checked for loose connection. Also check for condition of the coupler lock if equipped.

“A”: Check for loose connection |
3)Using a test male terminal, check the female terminals of the circuit being checked for contact tension.
Check each terminal visually for poor contact (possibly caused by dirt, corrosion, rust, entry of foreign object, etc.). At the same time, check to make sure that each terminal is fully inserted in the coupler and locked.
If contact tension is not enough, rectify the contact to increase tension or replace. The terminals must be clean and free of any foreign material which could impede proper terminal contact.

Voltage check
If voltage is supplied to the circuit being checked, voltage check can be used as circuit check.
1)With all connectors/couplers connected and voltage applied to the circuit being checked, measure voltage between each terminal and body ground.
2)If measurements were taken as shown in the figure and results were listed in the following, it means that the circuit is open between terminals “A” and “B”.
Voltage between
“A” and body ground: Approx. 5 V “B” and body ground: Approx. 5 V “C” and body ground: 0 V
3)Also, if measured values are as listed following, a resistance (abnormality) exists which causes the voltage drop in the circuit between terminals “A” and “B”.
Voltage between
“A” and body ground: Approx. 5 V
“B” and body ground: Approx. 5 V – 2 V voltage drop
“C” and body ground: 3 V – 2 V voltage drop

Short circuit check (Wire harness to ground)
1)Disconnect the negative (–) cable from the battery.
2)Disconnect the connectors/couplers at both ends of the circuit to be checked.
NOTE
If the circuit to be checked branches to other parts as shown, disconnect all connectors/ couplers of those parts. Otherwise, diagnosis will be wrong.
00-7 Precautions:
3)Measure resistance between terminal at one end of circuit (“A” terminal in figure) and body ground. If continuity is indicated, there is a short circuit to ground between terminals “A” and “C”.

Fuel and Oil Recommendation
B718H10101005
Fuel (For USA and Canada)
Use only unleaded gasoline of at least 87 pump octane (R/2 + M/2) or 91 octane or higher rated by the research method.
Gasoline containing MTBE (Methyl Tertiary Butyl Ether), less than 10% ethanol, or less than 5% methanol with appropriate cosolvents and corrosion inhibitor is permissible.
Fuel (For Other Countries)
Gasoline used should be graded 91 octane (Research Method) or higher. Unleaded gasoline is recommended.
Engine Oil (For USA)
Oil quality is a major contributor to your engine’s performance and life. Always select good quality engine oil.
Suzuki recommends the use of SUZUKI PERFORMANCE 4 MOTOR OIL or equivalent engine oil. Use of SF/SG or SH/SJ in API with MA in JASO. Suzuki recommends the use of SAE 10W-40 engine oil. If SAE 10W-40 engine oil is not available, select and alternative according to the chart.
0A-5 General Information:

I310G1010005-01
Brake Fluid
Specification and classification: DOT 4
! WARNING
Since the brake system of this motorcycle is filled with a glycol-based brake fluid by the manufacturer, do not use or mix different types of fluid such as silicone-based and petroleum-based fluid for refilling the system, otherwise serious damage will result.
Do not use any brake fluid taken from old or used or unsealed containers.
Never reuse brake fluid left over from a previous servicing, which has been stored for a long period.
Front Fork Oil
Use fork oil SS8 or an equivalent fork oil.
Engine Coolant Recommendation
B718H10101011
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 inhibitor 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 antifreeze/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)
3 250 ml (3.4/2.9 US/Imp qt)
For engine coolant mixture information, refer to “Engine Coolant Description in Section 1F (Page 1F-1)”.
! CAUTION
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
B718H10101006
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.
1)Keep to these break-in engine speed limits:
Speed limits
Initial 800 km (500 miles): Below 4 500 r/min Up to 1 600 km (1 000 miles): Below 7 000 r/min Over 1 600 km (1 000 miles): Below 9 500 r/min
2)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 9 500 r/ min at any time.
Cylinder Identification
B718H10101007
The four cylinders of this engine are identified as #1, 2, 3 and #4 cylinder, as counted from left to right (as viewed by the rider on the seat).
