To be honest, the amount of detail you are asking for/expecting is 1), difficult to gather into one cohesive whole, and 2), somewhat unnecessary.
While it is good to learn the ins and outs of your bike and engine, it's a bit much to expect to know everything there is to know before even assembling your kit.
Most of what you NEED to know is related to a few categories: maintenance, repair, tuning and how to ride. When I say how to ride, I mean this. Two strokes have many tuning capabilities that can get the engine to perform in different ways. Depending on how it's tuned, riding it in a way that it's not tuned for can sometimes be bad for the engine.
As you go along, you will begin to learn things. You will start learning how to ride from day one, becoming more intuitive of your surroundings and riding accordingly. This is something no book can teach.
You will learn tuning as you read through the forums and decide what you want your bike to do. There are limits, but there are some modifications which range from the simple external mods to the extreme internal modifications that can increase these limits. But the farther you push, the riskier it can be if you don't know what you're doing. Don't go digging into the internals of the engine until you have a very good idea what you're doing and a high level of understanding regarding tuning.
Maintenance and repair. You will learn some of this right away, the rest as you go and we are here to help. With no prior mechanical experience, your first build is not likely to come out "pristine" without help. Fortunately, that's what we are here for. Some parts are likely to fail during assembly, some will need to be replaced and some can be creatively repaired. We can suggest some creative repairs, as some are safe and acceptable and others are not.
