well good luck with the old girl. i have no idea what you are doing either... you didn't mention much about the bike itself. get some sea foam in the carbs with a syringe, after you drain them and let it soak. clean the tank out too, lots of info here on the subject. the tires need replaced if it has been sitting that long, for sure, even if not bald. get an agm battery and some new ngk plugs and crank her over, if it runs warm it up and replace the oil and filter right away. best bet is to replace all fluids and lube the splines. just surf the sight, you came to the right place.
oh and since you are young, take the rider safety course, and ride with some experienced riders if possible, they will have a lot of advice. make sure you search the site, learn all you can, practice emergency moves (you will need them sooner than later) and wear some protective gear.
my best advice,
1)make a habit of using BOTH brakes and your gearbox to slow down at EVERY stop so it becomes natural
2) look at every cage as though it is some *%#@%& idiot driving while eating a bowl of soup, texting, and changing a cd. because some of them are.
3) watch out for wild life, pets, kids, etc especially at dawn and dusk.
good luck with the bike!
