There are several "safety" switches involved in the starter circuit. You have to have the transmission in neutral or the sidestand up and the clutch lever pulled in. These switch combinations go through a diode pack to enable the starter relay under the tank. This relay sends switches on the solenoid switch behind the right side cover if one of the above conditions are met, the run/stop switch is on, the ignition is on, and the starter button is pushed. There are also 2 or 3 fuses involved.
