And also dump that gas out of the tank, never take someone elses assurance the gas is ok...You do not even know what the premix ratio is for that gas or how old it is since I am betting it is the usual gasoline with ethanol in it which breaks down quickly.
For breakin purposes on a new motor, you want to mix around 5.5 ounces of conventional 2 stroke oil to one gallon of Ethanol free gasoline if it is available where you live...Then shake it vigourously in a gas jug dedicated to just your bike before pouring it into the tank.
Anytime you refill that gas tank from the jug you will also need to shake it...each and everytime.
