aqaron thet are called rollers not bearings,they are in the case that the kickstart mech is in.there CANT be a chain in there only a drive belt ?so if you have the cover of and you can see the belt then you can also see a variator which is the round thing on the left and the clutch on the right,so take the nut off the end of the crankshaft which is in the middle of the variator it will be tight and you will have to hold the variator still or use an impact gun to take it off then take big round plate off and then pull the belf out the way and then you can take the back of the variator off by pulling it towards you,the rollers are in the back ,if there is a metal plate with 3 screws in it then undo it and change the rollers if the plate is missing then just take them out and swap them,i would leave the plate with the 3 screws in it off and dont fit it back on as this is a restrictor and will go faster top end if you leave it out,then just put it all back together again,easy peasy :)
