Keihn 1200 SI16 carbs - which z or bike?

[zed9]

These 34mm keihn carbs were fitted to a very poor condition Z900 A4 inport purchased from a company that says "runs on easy start" (year right!).

Which z if any are these from or bike as the only 34mm carbs fitted to zeds i have seen have a pull choke not a leaver. Cams are standard and pistons seem to be too looking through plug hole.

Fitted 26mm carbs, refurbished bike and was inspected while applying for V5 which arrived last week so happy daze .
