I don't think it will mess up anything.
There are needle bearings in the assembly between the driven cup and the driving clutch shoes.
Those are not supposed to be turning at any speed faster than idle and only for short periods. When the clutch is engaged, there's no motion between the two assemblies; the needle bearings don't move at all.
If you drag a scoot behind, you'll have those bearings spinning at many times their design speed for much, much longer than intended. Probably they'll burn up after an hour or so...what then? Maybe you'll be spinning the engine and never know it; more likely you'll shred the drive belt. In any event it'll be messy and expensive.
