Plastics, rear swing arm streched, axle, chain, gaurds and cosmetic stuff (screws, washers-everything swapped out to new when I bought it). twin carb (I'd guess most of you run the same based on your sigs)-no boost bottle. no speedo-so I dont have an actual top speed recorded. Not scary fast-but enough to hurt a spectator. Ive got a list of everything I spent at home-I should make a list if I ever sell it....
