How do you start a 70cc baja dirt bike?

To start a 70cc Baja dirt bike, first ensure the bike is in neutral and the kill switch is in the "run" position. Next, turn on the fuel valve and pull the choke lever if the engine is cold. Then, kick-start the bike using the kick starter or press the electric start button if available. Finally, once it starts, gradually release the choke as the engine warms up.
