SPEEDOMETER
If the speedometer, odometer or trip meter does not function
properly, inspect the speedometer sensor and connection of
coupler
1. If the speedometer sensor and connection are all
right, replace the meter with a new one.

• Remove the seat. (! 6-4)
• Remove the fuel tank side covers. (!6-5)
• Remove the fuel tank. (!4-52)
• Remove the air cleaner box.
• Disconnect speedometer sensor coupler.
• Remove the speedometer sensor
2 by removing its mounting
bolt.
• Connect 12 V battery, 10 kΩ resistor and the multi circuit
tester as shown in the right illustration.

• Under above condition, if a suitable screwdriver touching the
pick-up surface of the speedometer sensor is moved, the
tester reading voltage changes (0 V → 12 V or 12 V → 0 V). If
the tester reading voltage does not change, replace the
speedometer sensor with a new one.
NOTE:
The highest voltage reading in this test will be the same as that
of battery voltage (12 V).
