Hi Peter, don`t just put the shim back in because it was there before, I would build up the bottom end without the shim and with the distance piece in place between the upper rear bolt holes, then check the end float by levering the flywheel over to one side and then the other side a dial indicator is best but you can do it with slip gauges and feelers, you really want a minimum .015″ much over this then you need to start using shims, If you only need to use one shim I would use it on the right side this goes towards keeping the primary chain away from the N/S crankcase, best of luck.
