Yoy will find on the 750 Sport the chain adjustment figure on the swinging arm is incorrect, if you adjust the chain to the given figure it will be as tight as a fiddle string when the suspension is compressed, best way is to set it to a figure of about 50mm slack then compress the suspension untill the arm axle shaft and centre of the engine sprocket are in alignment and check it adjusting acordingly. hope that is of some help.
