Just wondering, but does the gas gas sprockets cross reference with any other bikes? I want to keep stock gearing but my local parts unlimited dealer isn't having much luck finding sprockets for the Gasser. He found a stamped steel rear from sunstar but it is a 49 instead of a 48 and we're having no luck finding fronts... I'm hoping to run just a basic sunstar aluminum rear with steel front and DID chain but so far we're spinning in circles.
