Is there any official thing that I must do to be a part of this? I have found the site to be useful. I have an ´83GSX 750 ES, but it says GS 750 ES on the side panel. What do I really have? Is there a difference? I don´t know a lot about it, but am learning...I have put about 500 miles per week on it in the last four weeks I´ve had it. Addicted. Will learn much soon. Thanks! zuma
