Guy said it was bored .40 over with ten hours on it, he did the work his self, there seams to be some sorta resido around the gasket meeting surfaces on the out side, but it was dried up and wouldnt come of by scratching it, theres one small crack in the plastics by the raditor, the rad is dented in some near the bottom, it starts in one kick, when i rode it there was a rattle it wasnt coming from the engine but you could easily hear it, there were no knocks or anything sounded good, but the left foot peg area was wobbling but the bolts wernt in the whole way but he said they wouldnt go in further after he put the nerf bars on, also the part where you screw the throttle cable in is broken so ill have to order a new one
