I recently picked up two 650sx's. One is stock and the other is not. I am not sure what is done to the second, the guy I got it from simply said it has a "big bore" motor. It has a pipe and a different head on it. Side exhaust on it ('89) sounds great. It has different bars and ride plate. It also has a trim lever and cable that is cut off on the back. The trim mechanism is missing and this is the nozzle that is on it. With the top part missing this thing is really light in the nose and porposes so bad it is barely rideable. I ordered a stock nozzle but am wondering if anyone is familliar with this set up and if I can get parts for it to get the trim lever operational again. Also any help identifying the aftermarket parts is appreciated. I am not new to pwc but these are our first standups. My teenage boys are addicted and already wanting to mod the other ski.
