do you want a sensibloe answer?unlike the p*n*s who has already answered you sad little sh*t.ok take the left hand engine cover off leave the kick start bolted to the shaft ,you will see a pulley on the left called a variator and a pulley on the right called the clutch bell undo the nut on the end of the variator its tight so you will need either an impact gun or a tool to hold it still while you undo it,then pull off the outside of the variator and pull the bel out of the way try to pull the belt tight soit pulss down intot he rear pulley it will make it easier to refit, then take off the rest of the variator some rollers may fall out but dont worry,on the back of the variator you will see 3 screws undo them and take off the plate behind it (restrictor)then check the rollers are ok they are 6 little roll shaped things clean them and put a little bit of grease on them as they dont roll very well anyway just do alot of sliding,put on the outside cover and the 3 screws and refit it all use some loctite on the nut on the end of the crank as they come loose and make sure you do it up tight.
