What was the last air-cooled in-line 4 from Big K?

I was thinking maybe it was the Zephyr 550/750 but it seems to me they made something after that. Were any of them FI?

I have a nice red Zephyr 750 in my "get to this some day" shed.

1100 Zeph was the last big aircooled four but the engine has no real lineage to the earlier Z900/1000/1100 engines.
The GPZ1100 B1/B2 and GPZ1100A Unitracks and GPZ750 turbo were injection.
The rest were VM slide or CV carbs.

I think the 2005 KZ1000 P24 is one of the later ones.
