Flywheel Magneto
Stator Installation
Route the wires according to the Cable, Wiring, and Hose
Routing section in the Appendix chapter.
Install the stator and tighten it.
Torque - Stator Bolts: 7.0 N·m (0.7 kgf·m, 61 in·lb)
Install the crankshaft sensor and wiring holder [A].
Run the magneto leads under the holder and sensor.
Torque - Crankshaft Sensor Bolts: 7.0 N·m (0.7 kgf·m, 61
in·lb)
Apply silicone sealant around the circumference of the
wiring grommet.
Set the stator wiring grommet [B] securely in the notch
[C].
Install the magneto cover (see M agneto Cover Installa-
tion).
Flywheel Magneto Inspection
There are three types of magneto problems: short, open
(wire burned out), or loss in flywheel magnetism. A short
or open in one of the coil wires will result in either a low
output, or no output at all. A loss in flywheel magnetism,
which may be caused by dropping or hitting the flywheel
by leaving it near an electromagnetic field, or just by ag-
ing, will result in low output.
Check the magneto output voltage, do the following pro-
cedures.
Push down the stopper [A] and remove the magneto lead
connector [B].
Connect the hand tester [A] to the connector [B] as shown
in the t able 1, using the needle adapter set [C].
Start the engine.
Run it at the rpm given in the table 1.
Note the voltage readings (total 2 measurements).
Special Tool - Needle Adapter Set: 57001–1457

If the output voltage shows the value in t he table, the mag-
neto operates properly.
If the output voltage shows a much lower reading than that
given in the table indicates that the magneto i s defective.
To check the stator coil resistance as follows.
Stop the engine.
Disconnect the auxiliary leads.
Connect the hand tester as shown in the table 2.
Note the readings (total 2 measurement).
