I am another newbie and am excited about getting another bike. I hear alot of people talking about mods to the gs. I am getting a 1991 gs and want to get a solo tail and a ducati monstor fairing for it does anyone know where I can get these?

Welcome!

The only thing I can think of for a solo tail is to order an Airtech CBR600F2 or R6 track plastics, but search on that here first.  The Ducati bugscreen is probably available from...Ducati...or you can search fleabay, or craigslist.org.

Thanks!
