Page 45 2-24 PERIODIC MAINTENANCE BRAKE FLUID LEVEL CHECK • Keep the motorcycle upright and place the handlebars straight. • Check the brake fluid level relative to the lower limit lines on the front and rear brake fluid reservoirs. • When the level is below the lower limit line, replenish with brake fluid that meets the following specification.
Page 46 PERIODIC MAINTENANCE 2-25 Rear brake The extent of brake pad wear can be checked by observing the grooved limit line A on the pad. When the wear exceeds the grooved limit line, replace the pads with the new ones. (!9-63) Replace the brake pads as a set, otherwise braking performance will be adversely affected.
Page 47 2-26 PERIODIC MAINTENANCE AIR BLEEDING FROM BRAKE FLUID CIRCUIT Air trapped in the brake fluid circuit acts like a cushion to absorb a large proportion of the pressure developed by the master cyl- inder and thus interferes with the full braking performance of the brake caliper.
Page 48: Tires
PERIODIC MAINTENANCE 2-27 REAR BRAKE • Bleed air from the rear brake system in the same manner as front brake. # Air bleeder valve: 7.5 N·m (0.75 kgf-m, 5.5 Ib-ft) NOTE: The only of between operation from bleeding the front brake is that the rear master cylinder is actuated by a pedal.
Page 49: Steering
2-28 PERIODIC MAINTENANCE TIRE PRESSURE If the tire pressure is too high or too low, steering will be adversely affected and tire wear will increase. Therefore, main- tain the correct tire pressure for good roadability and a longer tire life. Cold inflation tire pressure is as follows. % Cold inflation tire pressure Solo riding: Front: 250 kPa (2.50 kgf/cm , 36 psi)
Page 50: Rear Suspension
PERIODIC MAINTENANCE 2-29 REAR SUSPENSION Inspect every 12 000 km (7 500 miles, 24 months). • Remove the under cover. ($9-41) Inspect the rear shock absorber for oil leakage and check that there is no play in the swingarm. Replace any defective parts if necessary.

Page 54: Sds Check
PERIODIC MAINTENANCE 2-33 SDS CHECK Using SDS, take the sample of data from the new motorcycle and at the time of periodic maintenance at your dealership. Save the data in the computer or by printing and filing the hard copies. The saved or filed data are useful for troubleshooting as they can be compared periodically with changes over time or failure conditions of the motorcycle.
Page 55 2-34 PERIODIC MAINTENANCE Data at 3 000 r/min under no load Approx. 3 000 r/min Check the water temperature. XX ˚C ˚ Check the manifold absolute pressure #1. XX mmHg Data at the time of racing ˚ Check the manifold absolute pressure #1 in according with the throttle valve opening.

Page 204: Precautions In Servicing
FI SYSTEM DIAGNOSIS PRECAUTIONS IN SERVICING When handling the component parts or servicing the FI system, observe the following points for the safety of the system. ELECTRICAL PARTS CONNECTOR/COUPLER • When connecting a connector, be sure to push it in until a Click click is felt.
Page 205: Fuse
FI SYSTEM DIAGNOSIS • When connecting meter probe from the terminal side of the coupler (where connection from harness side not being possi- ble), use extra care not to force and cause the male terminal to bend or the female terminal to open. Connect the probe as shown to avoid opening of female ter- minal.
Page 206 FI SYSTEM DIAGNOSIS • When disconnecting and connecting the ECM, make sure to turn OFF the ignition switch 1, or electronic parts may get damaged. INCORRECT • Battery connection in reverse polarity is strictly prohibited. Such a wrong connection will damage the components of the FI system instantly when reverse power is applied.
Page 207: Electrical Circuit Inspection Procedure
FI SYSTEM DIAGNOSIS 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 circuits are as follows. As the cause can exist in the connector/coupler or terminal, they need to be checked carefully.
Page 208 FI SYSTEM DIAGNOSIS Continuity check • Measure resistance across coupler B (between A and C in the figure). If no continuity is indicated (infinity or over limit), the circuit is open between terminals A and C. 1 ECM • Disconnect the coupler B and measure resistance between couplers A and B.
Page 209 FI SYSTEM DIAGNOSIS SHORT CIRCUIT CHECK (WIRE HARNESS TO GROUND) • Disconnect the negative cable from the battery. • 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.
Page 210: Using The Multi-Circuit Tester
FI SYSTEM DIAGNOSIS USING THE MULTI-CIRCUIT TESTER • Use the Suzuki multi-circuit tester set (09900-25008). • Use well-charged batteries in the tester. • Be sure to set the tester to the correct testing range. USING THE TESTER • Incorrectly connecting the + and - probes may cause the inside of the tester to burnout.
Page 211: Fi System Technical Features
5-10 FI SYSTEM DIAGNOSIS FI SYSTEM TECHNICAL FEATURES INJECTION TIME (INJECTION VOLUME) The factors to determine the injection time include the basic fuel injection time, which is calculated on the basis of intake air pressure, engine speed and throttle opening angle, and various compensations. These compensations are determined according to the signals from various sensors that detect the engine and driving conditions.
Page 212: Compensation Of Injection Time (Volume)
FI SYSTEM DIAGNOSIS 5-11 COMPENSATION OF INJECTION TIME (VOLUME) The following different signals are output from the respective sensors for compensation of the fuel injection time (volume). SIGNAL DESCRIPTION ENGINE COOLANT TEMPERATURE SEN- When engine coolant temperature is low, injection time (vol- SOR SIGNAL ume) is increased.

12-2 EMISSION CONTROL INFORMATION EMISSION CONTROL SYSTEMS FUEL INJECTION SYSTEM VZR1800 motorcycles are equipped with a fuel injection system for emission level control. This fuel injection system is precision designed, manufactured and adjusted to comply with the applicable emission limits. With a view to reducing CO, NOX and HC, all of the fuel injection volumes are stringently controlled with the programmed injection maps in the ECM by varying engine conditions.
Page 536: Crankcase Emission Control System
EMISSION CONTROL INFORMATION 12-3 CRANKCASE EMISSION CONTROL SYSTEM The engine is equipped with a PCV system to prevent discharging crankcase emissions into the atomo- sphere. Blow-by gas in the engine is constantly drawn into the crankcase, which is returned to the combus- tion chamber through the PCV (breather) hose, air cleaner and throttle body.
