125-200cc CR144 what’s needed?

If I am getting an OE cylinder and head from 144 kit with the powervalves what else do I need?
The main issue I think I might have is using the 2009 up kit with my 2000 lower half. Anything change with power valve control? Do I need the newer CDI or should the ignition curve be the same? I was looking at getting an HPI CDI or a JD for later KTM so I can go dual map. Fast by Ferraci sold out of theirs and they no longer offer mapping changes.

Thanks in advance for any advice!
