Get a hot rods crank nothing else!!! A word of advise unless your talking to a banshee specific builder to handle machine work and build you will have problems I've seen more than one come through my door from a local shop that was terrible a whole bunch of parts off eBay slammed together. Pick one guy to get everything from do it once do it rite,you can go broke saving money

You need to post some pics. The "one cyld with 2 bores" leads to the assumption they are aftermarket cylds. Start posting pictures and any numbers/letters you're seeing.

There are part numbers stamped on top of the pistons but you may have to take some emery cloth to them to be able to see it. They will be kind of faint

 

People on here have already told you, there is part numbers on the connecting rods on the crankshaft to identify what you have. Such as the "29L"

 

Posting pictures is the best way to get better help. You can use Photobucket or Tapatalk. Your choice on which you choose.

Piston. Above orientation arrow. 16503-10. Below arrow. S50-520F6800.

Crank is welded. Then on the cylinder, under the LEFT reed cage housing is K1143. Under the RIGHT housing someone used an engraver and engraved what looks like 1958. Hopefully pics will load. If not, this is the best I can do.

Ok. Tried uploading pics from my phone and can't figure out how to do it. The dome has the number 19 on the side of it. So I assume 19cc domes. Looked at crank case a little better. And I looks like the cases have been hand clearances for the crank. I'll try to log on to the computer later today and see if I can upload the pics that way.

That goes without say, however I am the 2nd owner if this bike. I have no idea who built this engine before me. So I'd like to identify all the parts I'll be replacing. That way I can upgrade them or do a direct replacement of them.
