What did Ian do to save you some headaches, tell you that there is a search feature or that there is a wiki. Those are things you could have figured out on your own.
Dumb questions are the ones that are asked without any prior knowledge of what you are doing. They make an abundance of kits for puch motors, but instead of trying to find that out, you wasted some of your time asking an open ended question, can you put a 70cc kit on this motor, I dont know, are you really qualified to attempt it if you cant figure out that they sell tons of kits for the bike you wanna put them on.
