I have replaced all the bearings in the chain case and on the secondary drive clutch side. There are spacer washer that are used to adjuct the secondary drive. The inside dimension of all the washers are the same size. The problem is that when I place a spacer on the left side of the secondary clutch, its diamater is larger than the diameter of the aluminium sleve of the clutch. Is ths normal? I am afraid that as the clutch and washer rotate, the washer will damage the end of the aluninium sleve.
