Replacement Carburetor Jets

After many hours of research, I was nearly certain that the jets in the Seca II carburetor (Mikuni BDS26) were a N102 main jet and a VM28 pilot jet. Oizarod's jetting exercise has pointed out that this is not correct. So I need help. What are the appropriate jets to order for the Seca II carburetor?

I suspect the correct jets are the N100 and the VM28 based on measurements (8mm head on the stock main and a 2mm bleed on the stock pilot). What do you all think or have you used that work?
