First off welcome to the club. You will find that a 2stroke is a finicky beast but when tamed properly (ie maintained/jetted/etc) it will prove to be one awesome ride. A few pictures in the thread here will help us help you in seeing how the bike is set up.
Your best bet is to start with the service manual if you have it or buy a Clymer repair manual. It will give you the best baseline understanding of your bike and the standard maintenance and repair. It also gives you a guide of what to check before and after each riding session and what to keep an eye on during your ride.
