Testing Oil Pump
Pressure
NOTE: The engine must be warmed up to the speci-
fied temperature for this test.
1. Connect the Tachometer to the engine or utilize the
LCD (if equipped).
2. Connect the Oil Pressure Test Kit to the oil pressure
test port.
CF264C
NOTE: Some oil seepage may occur when installing
the oil pressure gauge. Wipe up oil residue with a
cloth.
3. Start the engine and run at 3000 RPM. With the oil
temperature at 60° C (140° F), the oil pressure gauge
must read 1.2-1.5 kg/cm
2
(17-21 psi).
NOTE: If the oil pressure is lower than specified,
check for low oil level or a defective oil pump.
NOTE: If the oil pressure is higher than specified,
check for too heavy engine oil weight (see General
Information), clogged oil passage, clogged oil filter,
or improper installation of the oil filter.
Vacuum Pulse Fuel Pump
The vacuum pulse fuel pump is not a serviceable compo-
nent. If the pump fails, it must be replaced.
TESTING
1. Disconnect the fuel pump/carburetor hose at the fuel
pump; then connect a hose and suitable pressure
gauge to the fuel pump output fitting.

2. Start the engine. Fuel pump pressure should read
0.18-0.25 kg/cm
2
(2.5-3.5 psi).

REMOVING
1. Remove the seat; then remove the three clamps
securing the gas hoses and vacuum hose and discon-
nect the hoses.
! WARNING
Whenever any maintenance or inspection is made on
the fuel system during which there may be fuel leakage,
there should be no welding, smoking, open flames, etc.,
in the area.
AT THIS POINT
Prior to removing the vacuum pulse fuel pump, the fol-
lowing check should be performed to determine that
removal is necessary.
