They should come with all instructions and everything you need. May be cheaper to buy your own tools than to pay someone. Then if you get a moped, you can work on it yourself. I wouldn't have bought that kit. The money you payed I'm guessign about 200 or more, could have been used to buy or save for a ped. Try selling that kit. It will only cause trouble. Of course I'm basing this on what I've heard. I wanted to buy one, researched it, and quickly changed my mind. If they were higher quality, it would be kinda cool.
