how do i replace a drivebelt speedfight?

take the left hand cover off the engine,there are two main components in there a variator which is bolted to the end of the crankshaft and a clutch which is bolted to a shaft which makes the rear wheel turn arpund ,remove both of these and then you can simply fit the new belt,you may need an air impact gun or a holding tool for keeping the variator still while you undo the nut, ok hope thats helps
