where to find parts for the 2004 GS500F?
it is so hard to find
i mean all i want is an exhaust
and maybe a few other things
i'm new, plz recommend some parts and ideas of what i can do to my bike
is putting on a turbo a good idea?

You might still be able to buy a wileyco off of ebay and maybe Srinath has a flange laying around.  I think you're a little off basis by asking if you should put a turbo on your GS; why wouldn't you just buy a faster bike?

i love my GS500F so much i want to keep it as long as possible
(just kidding)  but this is my first bike, i did everything on this bike
anybody from NY, hit me up, maybe we can start a group in NY!!

Gotta turbo the first bike!  

Get some riding around town under your belt.  Then take some track days and learn what really fast riding is like - and most importantly, what really fast riders are like.  Then decide what you want to do, bikewise.
