after i noticed a big crack at the neck of my '96 XR600 frame, i took it to a friend of mine who has 20 years of welding experiance. after he took it apart and looked into it, he is convinced that it is a factory defect. any one ealse have this problem? a honda rep told me that it DOES NOT HAPPEN and that it DID NOT HAPPEN (he thinks i made it up?) on the phone. now i own a yamaha, and am looking into a cannondale. i would like to get a new frame. does anyone have a frame for sale, or maybe a parts bike with good frame and bad motor? if so, let me know. thanks.
