If thats all it did then your kinda lucky if you can see it that way. You should be able to get a new sleeve, piston and rod for about 50 bucks (estimation) depending on what motor you have. If you have an expesive motor i would rebuild it but if the motor is not so expesive it would prolly be good to just get a new motor. But if u do decide to rebuild the motor make sure that you get all the little pieces of metal out of the crank case. Flush the crank case out with some fuel. You will just have to make sure you get all the metal pieces out before you reabuild and run the engine again Well what ever you decide to do good luck
