Too Much Motor Oil

[manimal]

Is there any potential damage running the motor with too much oil (over filling)? If any, what are some expected results?

The amount that you overfill and the design of the engine determine the ill effects.
Basically not much happens unless you add enough oil that the crankshaft hits the oil as it revolves on each stroke of the cylinders.
The crankshaft will  then cause the oil to froth and the lubrication capability of the oil will be degraded by the air entrapped in the froth.
Too much froth and the oil pump may quit pumping.  But usually that is pretty much extra oil.  The design of the crankshaft and the oil pan size and shape define the maximum oil level which is a lot more than the designated operating oil level.

But it is best to suck some out or remove it via the oil drain plug. 
Easiest may be to remove the spin-on oil filter (if that is what your bike uses)and drain the oil out of it.

You won't find a better answer.
