My Kawasaki FX730V calls for NGK BPR4ES plugs, what I'm Finding is the BPR4ES-11, what is the eleven on the end of the number mean, or is this BPR4ES-11 a totally different plug?

That is a pre gapped plug and the 11 is the gap code

The gap for -11 is .044". This means that this plug needs to have the gap closed up to I think .030" for use in a FX730.
Special sparkplug gap pliers when used will hold the "J" tang and keep it perpendicular to the center electrode while closing up the gap to the preset opening.

Does NGK have a chart online that shows plug number break down?

Thanks

You can get a BPR4ES without the #11 preset gap Right?
