Thats a load of crap. Crank balance has nothing to do with one side of the engine to the other. It has to do with reciprocating weight. The reason it is not recommended has nothing to do with balance. It is because you have no heavy reciprocating mass to resist kickback. And when it does kickback (and it will) you can smash the kickstart gear and destroy its housing and your case. This is only the case with some motors because of kickstart design. The monster motor is one. There are also plenty of guys who do run inner rotor and lighten slinger. There are also plenty of guys who run one with the crank mounted clutch. Honda guys have been doing it for years.
EDIT -Just think about what your saying.. do you think the balance is correct with an inner rotor on one side and a full size slinger on the other? The balance from one side to the other was closer with the flywheel on. Shaving the slinger after rotor install actually brings the balance closer again. It has to do with the reciprocating weight on the bottom end to help keep the motor spinning at low revs and to resist kickback.
