5. Check the oil pressure. Check the oil
pump, oil leakage, and oil strainer if out
of specification.
Oil pressure (reference data):
650 kPa (6.5 kgf/cm
idle speed (700 r/min)

Checking the oil pressure sensor

1. Connect the test harness (3 pins) to the
oil pressure sensor.
2. Start the engine and warm it up for 5 min-
utes.
3. Measure the oil pressure sensor input
voltage. Check the wiring harness con-
nection or replace the ECM if out of spec-
ification.
4. Measure the oil pressure sensor output
voltage. Replace if out of specification.

Checking the valve clearance

1. Remove the flywheel magnet cover and
ignition coil cover 1.
2. Disconnect the ignition coil couplers 2
and spark plug caps 3, and remove the
ignition coil bracket 4, spark plugs, and
cylinder head covers 5.
3. Turn the flywheel magnet clockwise and
align the "1TDC" mark a on the flywheel
magnet with the pointer b, and check
that "I" marks c and d on the driven
sprockets are aligned with marks e and
f.
