I thought about using the mini forum, but this beast is not exactly a mini.
Please help me get this beast jetted!

The bike belongs to a friend. She is quite small and wanted something to play around on. Being a typical motorcyclist, stock was not enough!
The bike now has a 74cc high performance kit (Head, cylinder, piston, pipe silencer) and a POS!!!! Dell'orto carb measuring a huge 19mm.
The kit came with a 95 main jet. The jet is so far off I cannot tell if it is rich or lean. The plug is BLACK, but the bike will not rev with a load on it. On the stand it is ok, but not with my fat ass driving it.
I dropped down to the 75 main that was stock in the original 14mm carb.. I am still getting a black plug, but it will now rev to 8000. I am thinking of trying the optional 71 jet. Still, how could the larger piston require leaner jetting especially after adding a larger carb???? Apparently this kits works well at sea level with a 95 main. The bike also uses oil injection , so I have no idea what ratio it is running at.
Buy some more jets, right??? WRONG!!!! The closest main is in oregon. They will cost about 10.00 each, if available.
This is one of the coolest bikes I have ever seen. I would really like to get this running for her. Any and all advise would be appreciated.
Studboy, I fully expect you to participate in the jetting experience. I will buy the pepsi if you will pry yourself off of the pocket bike.
Rich and Eric, I hope you will consider helping me. Should you decline, I will be forced to send the engine to you. I will then call hourly and ask to pick your brain, is it done yet, can I bore it to 82cc's, or , is a turbo available.
Overall this bike is cool, except for the fact it is spanish. It would be way easier to find bultaco parts.
