Sorry, got generations mixed up. Let me check with SV650 rider down road from here. She had this exact problem couple weeks ago. Tried her CDI box in other bike and it worked. Measured her crank-sensor at correct ohms, so that was good too. They were looking at borrowing scope next and tracing signal upstream on harness.

Couple things to check:

1. Power to CDI box?

2. Model-year of swapped-in engine? It has flywheel/crank-trigger teeth pattern for carbed engine and not EFI? How many teeth on outside of flywheel?
