It will run without it being plugged in, but if you remove the assembly you wont be able to start it as the starter clutch is all part of the rotor assembly on the back. You can tell quite easily if the bearings are shot simply, by stripping the rotor and spinning by hand. What need to be checked is wear on parts of the replacement rotor to ensure they're correct tolerance and the bearings aren't spinning, in their rebates or on the shafts.
As for back firing, normally crap exhaust systems, air leaks, not or badly mapped fuel system, cheap replacement high flow air filters or a mixture of all of it. So often I see all manner of after market crap on bikes which claim to increase power when in fact they do the opposite, remember noise doesn't equal power and power doesn't always mean better.
It's were the power increase is in the range and how it's delivered that makes all the difference.
