hi, a mini dirt bike idential to this a few months ago. i am wanting to start purchasing parts to upgrade it, though i dont have a clue what to buy and what each part does. a friend said something about buying a 70cc kit for it, is that the same as a big bore kit?
i have found a few parts which i believe to be good, can you people please tell me more about what they actually do and more to the point will they make the bike faster (top speed/acceleration)
