Have you checked the 2000 parts manual? The 97 models came with DVS. Since it is the same basic motor as yours chances are it has DVS. Download the 2000 parts manual from the mother site and check. The DVS kit is generally for 01 an up models. Be sure what year your bike actually is. Post a pic or give a description of the motor and we can tell you. Does your shifter have lightening holes drilled in it?
