Sure, you can do it!
Here's what I would do. Get a note pad and a pen. Write down the sequence that you remove things, such as 1. Remove seat, 2 Remove gas tank, etc. Use your phone or camera to take pictures before and after you remove something, this will help greatly with things like wire and cable routing. Bag and tag parts with their respective hardware, such as foot pegs, carburetor, etc., to keep from things from getting mixed up.
And just remember, if it came apart then it will go back together. Just reverse the order that you disassembled it.
Good luck and we are here to help you if you get stuck or have any questions.
