ok ive read all the threads about the petcock mod/rebuild but it never talks about the rubber parts on the selector side of the petcock.... theres a O-RING and SELECTOR PORT gasket in there that wears out just like the rest. the vacumn diaphram looks new but it still seeps gas past. im thinking the selector gasket in the front half is bad (round with 4 holes in it) .. the petcock is apart and cleaned. the selector gasket looks old and is semi-hard .... the girl that ownes the bike tried the XS650 gasket set but its not even close in size....:crazy: so where can i get the other rubber parts needed for this petcock ? thanks lance
