- Weak battery: The battery may not have enough power to turn over the engine. Try charging the battery or replacing it with a new one.
- Bad starter: The starter may be damaged or not receiving power. Check the starter motor and solenoid for damage or loose connections.
- Faulty ignition switch: The ignition switch may not be making good contact, preventing power from reaching the starter. Check the ignition switch for damage or loose connections.
- Engine is seized: If the engine is seized, it will not turn over even with a good battery and starter. Try to turn the engine over by hand using the kickstarter. If the engine is seized, you will need to have it repaired by a qualified mechanic.
- Pop starting with compression release: If the bike is pop-started while the compression release is engaged, it will not start because the piston will not be able to compress the air-fuel mixture. Make sure the compression release is disengaged before trying to start the bike.
