2004 GS500F mods

[sbloom67]

Ok, I have had this bike now for a month now and its fun to drive, but and I do say but.  I can not find a replacement for the stock exhaust, the windshield or a jet kit.  The dealer told me there wer a lot of changes over the 2002 model and there is nothing to replace anything yet.  I have also called everyone and anyone on my own and have not found anything.  How long does it take for these aftermarket items to come out ?
