Hi mate, I would get it checked out to be 100% sure that it is the chains just to be sure. I got my my parts from TPS rather than GSF. Here is a link to the guide in the premium members section for changing chains & it includes the part numbers as well. You will also need coolant & a clutch if your changing that as well. http://www.vr6oc.com/e107_plugins/forum/forum_viewtopic.php?107739 If you have no one to do the work then Tonyvrsc has done mine & quite a few other members so drop him a pm if you want more info.
