Yamaha Moto4 Won't Start

If your Yamaha Moto4 four-wheeler will not start up, you will have to troubleshoot the four-wheeler to figure out what is wrong with it. There are a variety of problems that can prevent your four-wheeler from cranking, and they vary from simple fixes to problems that require major repairs or a trip to a mechanic specializing in repairing four-wheelers.

      Check your battery. If you just rode your four-wheeler in the last day or two and now it will not start up, there is a chance your battery is dead. Check the switch for the headlights to make sure you did not leave it on, then check your battery's connection and wires. Hook a battery tester or charger up to your battery and see if it is fully charged or running too low to start your four-wheeler.

      Check the gas in your Yamaha Moto4. Just because your four-wheeler had enough gas to drive back to the house doesn't mean it has enough gas to crank back up. Check the gas tank to see how much fuel is in the four-wheeler. If you can not tell, add some fuel and see if your Yamaha Moto4 will start.

      Check your spark plugs to make sure your four-wheeler is still getting enough fire to crank. This may be the problem if you recently submerged your four-wheeler in water or it has been sitting in one location for a long time.

      Check your carburetor to make sure it is not stuck in one position or damaged. If the carburetor is not working properly, your Yamaha Moto4 will not get enough gas and may be unable to start.

      Check the air filter and make sure it is in the proper position. If the air filter on a Yamaha Moto4 is not in the proper position, the four-wheeler will not start.
