The one in the diagram is the replacement for yours (as far as I know). It looks just like the one I replaced on my 650L.

The one you have is the same one on my bike when I got it. Don't think it was original. That being said, when you replace, get one fromn Z1, not an OEM part (which suck).

The photo shows the early style petcock - same as on my '79 550E. I’ll measure the distance between mounting holes later tonight if that will help you id the correct part.

As far as OE verses aftermarket from Z1, my vote goes for OE. I haven’t been impressed with much of the K&L stuff (petcock mfr.), although it’s not junk either. OE stuff is pretty solid and hard to beat for quality.
