Modern Vespa

I have an lxv125 06, and randomly started running terribly and struggling to gain speed and revs, I took the bike to pieces and found a crack in the cylinder head, so I had a garage replace the head and install the mallossi 190 kit. Since then the bike hasn't started, I gave the garage just the engine block to work on just so I could transport it too and from. I've used a spare working ignition coil and brand new spark plug and the bike just won't spark, another issue I'm having is finding a replacement cdi for the ac19i unit as it has 14 pins plus the immobiliser, the only ones I can find online are 8 pin with no immobiliser. Can anyone help please I'm at wits end with this bike

I'm also looking for a performance cdi the only ones I can find are standard or don't fit
