Disconnect the magneto lead wire coupler.
●
Start the engine and keep it running at 5,000 rpm.
●
Using a pocket tester, measure the AC voltage
between the three lead wire. If the tester reading is as
follows, magneto is in good condition.

STARTER SYSTEM
The starter system is shown in the diagram below: namely, the starting motor, starter relay, starter switch and battery.
Depressing the starter switch (on the right handlebar switch box) while squeezing the front or rear brake lever energizes
the relay, causing the contact points to close which connects the starting motor to the battery.
