I can hear the starter but it isn't turning the motor over any suggestions?

If the starter on a Suzuki LTZ 400 is making noise but not turning the motor over, possible causes include:

1. Faulty starter clutch behind the flywheel.
2. Issues with the starter reduction gears located behind the three-bolt cover on the stator side.
3. Faulty starter relay or poor contact at the relay.
4. Loose or disconnected starter motor lead wire.
5. Open circuit or improper connector contact in the wiring harness.
6. Faulty ignition switch, engine stop switch, neutral switch, or starter button.

The loud pop could also indicate mechanical failure in one of these components.
