Sorry, but I'm not finding any working links in all the search results for this, but does anyone know where I can buy a 17T front sprocket for the first "gen" GS500? It seems something changed along the way so I don't know if the newer sprockets will fit the front countershaft on the older bikes.
EDIT: Nevermind, didn't realize that Amazon had JTF565.17 sprockets. Thanks for viewing anyway, guys.

amazon works as well.
