Engine lubrication symptom diagnosis
Oil pressure check
Check the engine oil pressure periodically. This will give a good indication of the condition of the moving parts.
| Note before checking the oil pressure, check the following.
|
- Start the engine and check if the oil pressure indicator light is turned on. If the light stays on, check the oil pressure indicator light circuit. If the circuit is ok, check the oil pressure in the following manner.
- Remove the left side cowling. Refer to “exterior parts removal and installation” in section 9d .
- Remove the oil pressure switch lead wire (1) and oil pressure switch (2).
- Install the special tools to the mounting hole of the oil pressure switch.
Special tool (a): 09915–74521 (adapter hose) (b): 09915–17410 (oil pressure gauge adapter) (c): 09915–77331 (oil pressure gauge (1000 kpa))
- Install the oil pressure switch (2) to the adapter.
- Warm up the engine as follows: summer: 10 min. At 2 000 r/min winter: 20 min. At 2 000 r/min
- after warming up, increase the engine speed to 3
000 r/min (observe the tachometer), and read the oil
pressure gauge.
If the oil pressure is lower or higher than the specification, the following causes may be considered.
Oil pressure specification 100 – 400 kpa (1.0 – 4.0 Kgf/cm2, 14 – 57 psi) at 3 000 r/min, oil temp. 60 °C (140 °f)

|
- Stop the engine and remove the oil pressure gauge and attachment.
- Reinstall the oil pressure switch. Refer to “oil pressure switch removal and installation” .
- Check the engine oil level. Refer to “engine oil and filter replacement” in section 0b .
- Install the left side cowling. Refer to “exterior parts removal and installation” in section 9d (page 9d- 6).

Carrying a passenger
Carrying a passenger, when done
correctly, is a great way to share
the joy of motorcycling. You will
have to alter your riding style
somewhat since the extra weight
of a passenger will affect handling
and braking. You may also need
to adjust tire pressures and suspension;
please refer to the ...
If a collision is imminent, do something
Many riders fear locking up their
brakes or haven't learned to
swerve to avoid an accident.
Many inexperienced riders (and
too many seasoned riders) use
only their rear brake in an emergency,
resulting in unnecessary
impacts in some cases and
unnecessarily high impact speeds
