    All machines do not carry oil

     

    This engine does not come equipped with an ignition system (CDI). Additionally, all engines undergo an oil-draining process before leaving our factory. Therefore, without an ignition system and with no oil remaining inside the engine, you will need to add engine oil (4T oil) during the initial setup after purchase.
