BIG question is , Did the bike run before it was tore down??? If you know anything about the engine, that will be of great benifit to you.
It the engine still together?

How many miles, did it smoke, knock, leak, does it have decent compression???
My guess is if it is all there and you can turn it over by hand it will be cheaper to have it gone through by a competent engine builder/shop.
Re use all parts that you can.
A good shop can tell you if the heads and valves,pistons, can be reused, etc,etc. It engine is all there and still together you can do a compression check your self.
If it were me and the bike has an elec. start I would keep IT. If you are planning on riding it elec is the way to go. If you want it more show than go, then strip everything off . IMO

The first thing I would recommend is a good service manual, then search for a good engine rebuild manual for harley sportster. You will need head and valve work. I think your bike was used in the leaded fuel days ,hardend seats at least.
