Shadow throttle

Hello, this topic has certainly been read by everyone once, but unfortunately I couldn’t find it here yet really…at least no solution. I got into the family of the moped riders quite new and since I am still under 25 (only in November) I will probably have to drive my baby first throttled, with which we are already on the topic: I would like to do this myself, however, have no idea how this can be done, but I want to save myself the money, it To do it in a workshop. For me, riding a motorcycle also means to be able to screw on your machine; if you don’t learn it, you just have to teach yourself and how to do it best? Just start my request to an experienced screwdriver: help me I want to install a throttle, but don’t know what I have to do for it and the www has not been really helpful to me to date. Cool would have been for example a guide with pictures or a Tex I would like to thank your Manuel in advance.
