No eBay APP ID and/or Cert ID defined in Kunena configurationThe one in your link has 46mm spacing between mounting bolts.
The 650's is 44mm.

I bought one of these manual petcocks for my '78 KZ650 C2.
Haven't installed it yet, will in the Spring when I fire her up again.
Not the best looking fuel valve, but works well as confirmed by another 650 rider.
It goes on reserve much earlier though I hear.

Vacuum petcocks.
Z1Enterprises.com should have a Suzuki petcock that will work. assuming they still carry it.
For OEM a KZ1000P petcock should work. I'm pretty sure it's 44mm, but ask before buying.

I would go with the Tour Max petcock linked earlier, or something similar - I'm sure your mounting hole spacing is 44mm.

EDIT: I wouldn't go too cheap on this though. I've tried a couple $15 ebay taps and they may as well have been sieves.

Yeah I was wondering about that. I bought the rebuild kit and its all new, so no reason it wont work. Found the port between the #1 and #2 carb meant for the line to the petcock, according to the internets. Im going to try it and see. I was also wondering can you just remove the diaphragm part and plug the input port? Probably. Either way, going stock, to see what happens. Also replaced my cam cover gasket yesterday, my shop is -4 Celsius right now so that sucked.

EDIT: This petcock has failed on me.
At just under 500 KMs, when set to ON, it barley flows.
When set to OFF, it constantly drips.
The lever is getting hard to turn.
Ethanol in the gas may be a contributing factor.
Haven't taken apart the petcock yet.
