1. Fuel . Make sure the fuel is turned on. If it is, check the fuel level. If the fuel tank is empty, that could be the reason why the bike won't start.
2. Choke. Make sure the choke is turned on. If the engine is cold, the choke needs to be on to provide extra fuel for starting.
3. Spark plugs. Check the spark plugs to make sure they are clean and properly gapped. If the spark plugs are fouled or worn, they will need to be replaced.
4. Air filter. Check the air filter to make sure it is clean. A dirty air filter can restrict airflow and cause the engine to run lean.
5. Battery. Check the battery to make sure it is fully charged. A weak battery will not provide enough power to start the engine.
6. Starter. Check the starter to make sure it is working properly. If the starter is not working, the engine will not be able to crank over.
7. Fuel pump. Check the fuel pump to make sure it is working properly. If the fuel pump is not working, the engine will not be able to get fuel.
If you have checked all of these things and the bike still won't start, you may need to take it to a mechanic for further diagnosis.
