Who would be interested in buying it?

cool.  thanks for all your replies. this is interesting stuff.

i mentioned the single because i have visions of a Royal Enfield sport bike...

well I 'd be willing to try and stab in just about any kind of engine so if a royal enfield sport tickles your giblets then so be it.

that sounds fresh, you'll make my wife jealous.

So I did a bunch of hunting and I got what I think is a good average for a used 125cc engine and came up with $3350...no warranty, though, so you'd learn how to rebuild top-ends! haha  Well you'd have to learn how to do that anyway.
