1. Low Battery: Check your battery's voltage to ensure it has sufficient power to start the motorcycle.
2. Faulty ignition switch: The ignition switch may be faulty, so try turning the key back and forth a few times or even wiggling it to see if it starts. If it does, you might need a new ignition switch.
3. Clutch issue: Make sure the clutch is fully disengaged by pulling the lever all the way in. If the clutch is not fully engaged, the bike won't go into neutral.
4. Faulty neutral switch: Check the neutral switch, as a faulty switch could cause the bike not to recognize when it is in neutral.
5. Low oil level: Ensure that the motorcycle's oil level is sufficient, as low oil levels can sometimes prevent the bike from shifting into neutral.
6. Drive chain issues: Make sure the drive chain is properly tensioned and lubricated, as chain problems might hinder shifting into neutral.
7. Faulty Starter System: If the battery voltage is sufficient and the ignition switch seems to be working properly, the starter motor, solenoid, or related wiring might be faulty, preventing the bike from starting or going into neutral.
If none of these troubleshooting solutions help resolve the issue, consider having the bike evaluated by a professional mechanic.
